An extension cord for electric saw how to fix. Mark PRS

CENTED ELECOMPILS: characteristics, operation, choice

Electric chain saw. an indispensable assistant with a variety of household and professional tasks. There is no special difference between the functioning of the power plant and the chainsaw. The difference is only in the type of engine. Many users positively speak about the operation of an electric drive, noting the ease of use and maintenance, the lack of need to refuel saw equipment with fuel and a long service life with proper use with proper use. Since it is correct to saw with an electric saw?

Before sawing, the equipment must be assembled. As a rule, the power unit itself is delivered in the collected form. Separately in the box there is a guide tire, a chain and a set of necessary keys for assembling and servicing a saw. When installing the chain on the tire, you need to be careful, since it is sharply sharpened.

It is important to observe safety measures and work in special gloves.

The setting of the chain itself is correct from the tire tip. Mount the tire with a chain on the bolts, start the chain on the asterisk and check the correct direction of the cloves of the chain. If the direction coincides with what is indicated on the lid, put it on and twist the fastener nut with the key that comes in the kit.

How to bring a cheap extension cord to mind

The article provides a real example of finalizing a cheap extension cord by enhancing electrical contacts and replacing the wire. The result was a good and reliable extension cord, in no way inferior to expensive analogues.

Currently, more and more portable electrical devices and tools are produced. These are electric drills, corner grinders, jigsaws, screwdrivers, scissors and the list can continue for a long time. For them, often for work, extension cords are required. And there are plenty of this product in today’s market: from cheap to expensive.

Extension cords that are more expensive can meet all the necessary requirements, and which are hardly cheaper. But since they are, then of course the people also buy them. Maybe they don’t know which is better, which is worse, and maybe for financial reasons. And once having bought cheap goods, he ceases to work normally, namely, as they say, “phase, that is, then it is not”.

The main reason that a cheap extension cord works poorly. poor.quality contact of a fork with a socket. Work with such an extension cord can annoy even “not irritable”. Take a hurry to throw away such an extension cord, it can be “brought to mind” and after refinement, he will “not yield” to his expensive in its parameters.

For example, I just have such an instance: a cheap extension cord. The length of the wire is three meters, a section of 0.5 mm2, a cash register for three consumers. “flies” poorly.

First we remove the top lid of sockets. There you can see two rows of contacts that are: two independent copper stripes, with roundings for the electrodes of the fork inserted into special grooves so that they do not “move away”. With this design, it is hardly possible to achieve, hard and reliable electrical contact.

We take out all these details and solder the network cord (if it is soldered). We take one group of contacts, fold with each other. how they should stand in the corps. And wrap the places between the roundings with a sticky tie out 2-3 boots. Now these details do not scatter, then the ends of these contacts are well plugged with tin using a soldering iron.

Then we wrap the tossed ends with a copper with a single.core wire with a cross section of 0.3. 0.5mm2 and solder to toss places. Next, we will replace the extension cord itself with a larger section. I had a piece of 2.5 meters. three residential and 2.5mm2 with a recent installation, so I will use it for the future extension cord. I use all the veins, which means one of the wires will have a larger section. We clean the ends and solder to the edges of the contact groups and the resulting design, already monolithic, insert into its place.

Until you closed the lid, you can try, as the fork is included in the outlet, with some non-coincidences you can fit and correct the roundings in the outlet. I assure you, the contact will be quite dense. the fork will be enough to be inserted into the outlet. After making sure that everything works “right, we close the lid. It remains to put a good fork at the other end.

You can also be wrapped with a copper wire (bandage) and also break the places that were wrapped with island. Island. a kind of indicator, after a long work, you can look at its condition by removing the lid from the outlet.

And a small parting word: since the forks “ours and euro” are distinguished by the diameter of the electrodes, for the forks of “ours”, determine some place, marking in any way. Here is such a finalization option. This is my personal, I think there are plenty of such craftsmen.

I photographed some points for clarity, if there is something unknown in the text.

This is how a factory execution socket is arranged:

We wrap the sites in the middle with electrical tape:

We wrap the middle sections with electrical tape. So everything looks after changes:

The contact parts of. It turned out a good and reliable extension cord.

This is what the extension cord turned out. Maybe someone will use my advice.

Operation Rules

During the operation of an electric extension cord, it is recommended to adhere to the following precautions:

  • Before use, inspect all nodes on the integrity of the insulating layer;
  • Do not exceed the rated currents for which the wire is designed;
  • Do not twist or bend conductive veins;
  • prevent the cable from entering the flooring, on the thresholds of the doors, etc. D.;
  • Avoid moisture penetration on the contact part.

Simple rules, you can make an extension cord with your own hands, which will meet your needs. At the same time, you do not need to have special skills and bear significant financial costs.

How to make a reliable extension cord (carry)

Both in everyday life and enterprises, it is often necessary to include electrical appliances in that part of the room or outside the rooms where there is no socket, from which you can power the necessary electrical appliance. This problem is easy to solve with the help of an extension cord, the so.called “carrying”.

In addition to the function of the extension cord. that is, the possibility of turning on the electrical appliance at a certain distance from the plug outlet, the carrying performs the branch of one plug connector into several, which is relevant if it is necessary to include several electrical appliances in one outlet in one outlet. For example, to include a computer to the computer’s network, several outlets are needed to connect a monitor, system unit, audio equipment, printer, router, etc.D.

Exteravators for technical needs are also widely used, which are used to connect various power tools and devices to a network.

The modern assortment of extension cords offers various options with different number of plug connectors, power, quality and, accordingly, price.

Which extension cord to choose?

The fact is that quite often it comes across not only poor.quality, but not at all corresponding to the declared characteristics extension cords. Such an extension cord will not work for a long time, especially if it is planned to use it to power a large load. The operation of low.quality extension cords can lead to a fire, the defeat of people with electric shock. What then to do in this situation?

In order to be sure that the extension cord is quite reliable and will not fail at the most inopportune moment, it is necessary to make it yourself. It is not difficult to make a carrier, the main thing is to choose the right structural elements correctly. Below we consider in more detail how to make a reliable extension cord (carrying).

Calculation of the required extension power power

For the manufacture of the extension cord, it is necessary to have a plug, a wire of the required length and a block of sockets for the required number of steam plugs. number of sockets in the block. To select these structural elements, it is necessary to be primarily guided by the power value (load current), which will proceed on this extension cord when electrical appliances are included in it.

Before choosing an extension cord, it is necessary to analyze whether it is possible to include these electrical appliances through an extension cord in a one or another outlet. That is, first of all, it is necessary to evaluate the condition of the home wiring. Very often situations arise when, after including an extension cord with several sufficiently powerful electrical appliances, electrical wiring is damaged.

A socket can be damaged, which includes an electrical appliance, wire (cable), which nourishes this outlet or contact connections in an intermediate distribution box or distribution panel. In this case, the extension cord can be good and quite reliable.

When choosing the extension power power, it should also be taken into account that almost all the sockets installed in everyday life have a nominal current 16 A. Accordingly, the maximum power of the extension cord, as well as the load included in it, should not exceed this value.

If it is necessary to turn on the larger load, it is necessary to use another outlet, also taking into account the features of one or another part of the electrical wiring.

Fix extension cord

For example, the extension cord must be used to turn on the electric heater and TV. The power of the heater la. 2000 watts, TV. 100 W, that is, the total power that will flow according to the extension cord is 2100 W, which corresponds to the load current of almost 10 A.

We analyze the state of the electrical wiring, especially the outlet, in which the carrying will be included. Particular attention should be paid to the quality of the plug connectors of the outlet.

If they have insufficient rigidity, then they will bask, the fork included in this outlet will also heat up. As a result, with a prolonged flow of load, there is a high probability of failure, both the socket itself and the fork for carrying. Perhaps this malfunction will not immediately make itself felt, but it can show herself at the wrong time, for example, when there is no one in the house, a fire may occur.

In order to understand how reliable the skeleton slot connector is, it is necessary to check for the heating of the carrying fork in which the electrical appliance of the relatively high power was long included (in this case, the electric heater). In this case, the more the fork is heated, the worse its contact connection with the socket connectors.

The same goes for a block of sockets for carrying. One of the most common causes of damage to extension cords purchased in the store are poor.quality plug connectors, which do not provide reliable contact with the forks of electrical appliances included in the carrying for carrying. In order to avoid such situations, it is necessary to choose more reliable blocks of sockets. with spring.loaded plug connectors. Such connectors provide a reliable connection of the power supply fork with a socket and during operation, as a rule, do not worsen their operational characteristics.

Also, when choosing a block of sockets, it is necessary to pay attention to the rated current of the load, which is indicated on their body. But besides this, the conductive elements of the outlet themselves must correspond to these characteristics.

Almost all blocks of sockets indicate a rated current of 16 A, but in fact, these sockets do not always withstand even 10 A. Therefore, before purchasing it is better to unscrew two screws and see what this product is inside is.

In addition, it is necessary to pay attention to the reliability of the terminals to which the supply cable is connected. In this case, the larger the area of ​​contact of the connected wire, the more reliable the contact connection will be.

The body of the unit block itself should be constructively reliable, without large gaps and with a reliable fastening of the back cover, so that during operation the possibility of touching a person to the live parts is excluded.

The next, no less important stage. correct selection of wires for carrying. When choosing wires, they are guided by criteria such as the type of wire, its cross section, length and number of cores. As for the type of wire, in this case, a flexible copper wire is selected, which has a double insulation layer.

Which extension cord to choose for home, garage, cottages. 5 rules.

The extension cord is the same necessary element of email.wiring in the house, like sockets, switches and other equipment.

In the store you can find dozens of their varieties. Which of them to choose and what parameters to pay attention to first of all.

Remember that the longer the carrying, the greater the voltage losses. For household appliances, the optimal length of the extension cord from 3m to 7m.

At the same time, the load can be connected to them with a capacity of not more than 3.5 kW (up to 16a) at the same time. It depends on the cross.section of the wire.

By the way, a lot of socket nests are needed not to simultaneously connect a large number of devices, but in order not to constantly pull the fork, thereby protecting from loosening the contacts.

Section of the wires for connecting the load of room equipment (TV, computers, refrigerators) choose at least 0.75mm2.

Many do not know, but all extension cords must be made and comply with GOST R 51539-99 (IEC 61242-95). It is called “extension cords and similar purposes on cable coils”. You can download here.

Here are the regulated sections of the wire for extension cords according to this standard:

Wire brand. most often PVS with polyvinyl chloride insulation.

In this case, the diameter of the wire itself (not a separate core) is advisable to have from 5mm and above. If not so, the manufacturer most likely saved on something-either on copper or on isolation.

A brand of kg can also be used, instead of PVS. It is more resistant to negative temperatures and changes in weather conditions. For street or garage use, such a choice will be more correct.

Pull PVS several times on the concrete floor, and its isolation will come to an end. Kg of more racks to such operating conditions. Other cable brands are also applicable:

Here are suitable sections of wires for high.quality carrying, and that in them you can safely include without the risk of overheating (refrigerators, washing machines, TV, drills, corner grinders, heaters, etc.D.):

Unfortunately, in factory execution, you will practically not find household extension cords with a section of 2.5 mm2 in stores. Unless these will be bobbins or coils of large length, from 50 meters and above.

And then, an increased section here is necessary first of all for the sake of reducing voltage losses, and not to connect a higher power.

Therefore, such models (with wires 2.5mm2, 4mm2 and higher) are often made on their own.

For more powerful devices, such as inverter welding machines, there is already a completely different class of products.

A quality model must have protection against stretching and bending the wire.

This applies to both the connector with the fork and the place of entering the conductors into the extension casing.

Never work with twisted wires. Firstly, this will sooner or later lead to damage to the veins, and secondly, such a cable will elementarily heat up.

Keep in mind that extension cords withstand the nominal load, only with a completely unrestrained cable. On the case, sometimes special icons are applied, with a maximum current with a wrapped wire and an unwound.

Before buying an extension cord, look at which fork is:

If the fork is not cast, and it can be disassembled, that is, the risk of running into a dubious product. It is such forks that is easiest to make a handicraft.

For the production of whole, at least some professional equipment is needed.

In addition, if your equipment with a fork without euro.distribution, then an extension cord with a Euro.zoom is contraindicated to you. The use of Euroadapers and adapters in this case significantly increases the transition resistance.

And also violates the grounding system, which can lead to the defeat of email.current. Some devices and tools are connected without grounding is elementaryly dangerous.

The transition resistance of one contact in the new model should be no more than 0.05m. During operation, it can worsen up to 0.1.

For what devices during the repair do you need construction carrying

Most often, wire extensions are used to connect manual power tools. So, carrying is usually needed for:

  • drones;
  • Shurovurtov;
  • Electrolobzikov;
  • Gaykovrtov;
  • sneakers;
  • soldiers;
  • milling mills;
  • Electronics.

Often more powerful devices are also connected to the carrying: welding machines, peorators, chipping hammers, corner grinders. Much less often, the coils-units are used for overall, almost stationary equipment: concrete mixers, compressors.

As an intermediate node, the device can also be used. Other carrying is connected to it. However, usually there is no need for this-the coil-extension, depending on the model, allows you to connect devices at a distance of up to 50 meters.

As a rule, carrying to tools and equipment with a capacity of up to 3 kW are calculated. When choosing, you need to take into account the maximum load. Electric plants are enough for a model of up to 1.3 kW. The power of the welding machine is higher, respectively, you will have to use a more expensive unit reelier.

The most common sections of wires in carrying

The permissible load level largely depends on the diameter of the cable on the extension cable. In addition, the cross section affects energy efficiency: increased allows you to reduce voltage loss. However, the rule “the more, the better” when choosing a carrying does not work. You can determine the optimal section, focusing on several points:

  • voltage;
  • current strength or total power of the tools;
  • type of wire by the number of cores and the material of the conductor;
  • terms of Use.

On an industrial extension cable, a 0.75 mm² cable is not found. this is an option for household equipment. Builders usually use wires with a cross section of the following values ​​(mm²):

Similar dimensions allow you to connect tools with a total capacity of up to 3.5 kW. They are ideal for energy networks 220 volts. The last two types are designed for use with the grounding circuit.

The length of the cord matters. if it exceeds 40 meters, it is better to buy an extension cable with a diameter of 2×2.5 or 3×2.5mm². The voltage drop in the carrying in the case of a powerful load will be lower.

When a network voltage is 380 volts, it is worth taking a closer look at 4×1 sizes.5, 5×1.5 mm².

Consider operating conditions. For example, if welding is carried out by an electrode of up to 3 mm, the cross.section of the veins is 2×2.5 mm² or 3×2.5 mm². In this case, the coil should have grounding. When welding with an electrode of 4 mm in intensive mode. without pauses. you need a diameter of 4 mm².

Each on the farm has several carrying vehicles. both to connect electrical appliances in residential premises, and for the work by a power tool on the street. Carries often help us out. after all, sockets are far from everywhere. But when using carrying, and especially carriers on coils, it is important to comply with the safety requirements and recommendations of manufacturers.

Why is it better to use extension cords on the coils and which model to choose for repair and work in the garden?

When using power tools or household devices that eat from the network, you sometimes literally feel “on a short leash”. And if you can’t do without an extension cord even inside the house, then there is nothing to say about work in the yard or in the garden.

Suburban household requires the application of hands almost constantly. You always need to drill somewhere, attach something, fix, assemble-strive. At the same time, the powerful length of the cord in power tools is usually not enough to reach the nearest outlet to reach the nearest outlet. And if, for example, in the basement or in the attic, the outlets are not provided at all, then you can’t do anything without an extension cord-you have to lay wires along the premises and stairs, involuntarily placing the “traps” for households along the road. The use of electric saws and welding machines in the construction of fences and arbors, mini-mine for cleaning paths and facades, cutting the lawns with electric lawnsions forces electric shoes to pull elongating cables from the house around the site and each time to unwind, and then wind them on hand, simultaneously and analyzing the nodes.

To save users from all these inconveniences, manufacturers produce extension cords on coils (drums) specially designed for internal and outdoor work. Such cables will not be confused underfoot (they can be rewinded exactly as much as necessary), as well as to break through, forming creases, which can lead to a short circuit. Due to the well.thought.out construction of the case, the coils are firmly on the ground or on any solid surface. In addition, it is easy and convenient to transport and store them: unlike those who strive to fall apart, they do not take up much space.

Schneider Electris offers as many as 5 groups of extensions on Thorsman coils designed for domestic or professional use and capable of providing users with the maximum level of security during work both inside and out of buildings. Devices are compact, have an attractive innovative design and ergonomic pens to roll cable and carry. An important advantage of models is the presence of a LED voltage on outlets and built-in thermal protection from overload.

Coilly.type extensors with automatic cable upcoming are a thing, of course, convenient, but for the time being for the time. The spring on which the operation of such a system is based sooner or later weakens, and this will not happen with a mechanical view

Products in the plastic frame of Thorsman Compact are light (weigh only 2.6 kg, overall dimensions 25 × 26 × 16 cm) are equipped with three-resistant HO5 VVF PVC cable with a length of 15 m and are equipped with four open sockets with grounding. The cross.section of the wires is 1.0 or 1.5 mm², which means nominal power up to 2.0 and 2.6 kW, respectively. Such extension cords have the degree of IP20 protection and are optimal for domestic use of indoors. There is one street device among them (IMT33136 model), in which the nests are covered from moisture from the hit with special lids.

For work at home, models on a metal frame with an elongated wire (20 and 25 m) Thorsman Classis are also offered. The cable in them is also a three.core, with a section of 1.5 mm², has a vinyl shell and provides a load up to 2.6 kW.
