Tipi cut darts

Rozmir pererazu straight-cut dart has a standard value. For a square rod, vikoristovuvanny large transformers, the thickness is 1.35 - 5.9 mm, width 3.8 - 14.5 mm.



The width of the joint and the width can be different, but the value may correspond to the norms of GOST 6324 - 52. Krіm tsgogo, it is practically impossible to inject on the eye a smaller beak of such a dart from a larger one.
An important part of the winding is a coil of the winding rod around the shear to the magnetic core. Fallow according to the nominal tension of the navantage strum is selected and required overtime coil. A round drіt is suitable for small strums, for a large strum, choose a straight-cut drіt. When preparing the windings, it is possible to vicorate a sprat of paralleled darts to increase the rethread of the darts.
The number of turns of the winding should be determined by the magnitude of the voltage. Coils of the winding are assembled into coils, electrical attachments can be folded from multiple windings or coils (transformers, motors), or better than one (throttles, electromagnets). At the process of winding the coil, the turns are superimposed on one by one (orders of winding), or one on the other (balls). The method of winding determines the type of winding as a result of winding.

Thin choice of winding rod

When choosing a brand, the choice should be made according to such criteria

1. Required class of heating capacity. For windings with high swedishness, the wrapping is not suitable for windings with enamel insulation, oskіlki temperature is higher than 160 - 170 degrees Celsius, the building will melt the cold ball.
2. The tovshchina of the insulating ball is allowed. The greatest amount of insulation can be combined with fibrous insulation. However, voicing them in the minds increased water content carelessly.
3. Vimogi to the necessary level of mechanical strength, moisture resistance, frost resistance and frostiness in the influx of chemical speeches.

Criteria for the capacity of winding wires

Fallen waters and brands of drotu are released from the bays, drums and coils. Winding the dart can be equal, unacceptably twisting turns. The ball of isolation can be equal, the presence of sweat to the ball is not allowed. The rows of windings are guilty but are equal and narrow, without enlightenment and ribbing. Admissible pouring of enamel at specific points is strictly regulated by the accompanying documentation.
Paper wrap drums and cats with a dart. For packing bays, we use matting or sackcloth. The coils dodatkovo fit into the boxes, it is permissible to carry 80 kg if they are not guilty.

On the skin bay, coils or drums, the wrapper is given a label with information about the brand of dart, virobnik, vase and diameter of the winding dart. It is necessary to save the wire in closed areas with low water level.

and rich other mechanisms.

Conducting windings on the vіdmіnu vіd іnshih іv іv provіdnіkіv yak іє yak іє іє іє є є є є є ї її її ії її її її її її її ії її ії ії ії ії ії ії ії ії ії ії ії її Use an even thin wire for windings and use a small ball of insulation. Ultra-thin winding conductors are manufactured using special technology for manufacturing especially thin conductors and electrical insulation materials.

Trivaly hour winding darts scrambled exclusively with middle ones. Today, for them, aluminum and other alloys are often vicorous, which may have a significant opir. Aluminum allows you to protect the road that scarce copper.

Classification

Winding rods are classified according to the material of insulation, the shape of the cut and the material lived.

Insulation material

Winding wires are prepared with advancing types of insulation:

1. Fibrous.
2. Enamel.
3. Combined.

fibrous

Provid, what can fibrous insulation, can promote mechanical strength. The thickness of the fibrous insulation is large and can reach up to 0.4 mm per piece. The chemical stability and moisture resistance of such darts is not high.

Fibrous insulation of wires, which are used for rewinding electric motors and rewinding oil coils, can include paprika, bavovnyana fabric, glassware, as well as asbestos fibers, lavsan, shovk. Qi fibers and fabrics are superimposed in a sprat of balls on a braided panchokha.

Emaleva insulation

The enameled insulation material is vinyl flex, metalvin, organosilicon base, polyether terephthalic acid, polyurethane.

Winding drіt, coating with special enamel, electrical strength, resistance to water, aggressive chemical speech. The peculiarity of the enamel winding wires is that the thickness of the insulated ball is too small (the maximum thickness is 0.09 mm). The value of enameled drotu PEL is small;

High-compact enamelled PETV, as well as PET-155, is used for windings of electric motors up to 100 kilowatts. Wire, enamel coating, grades PET-155 are victorious for a new series of electric motors; Emale darts can also have a high thermal stability, and keep the temperature up to 155 degrees.

Combined

Winding conductors with combined insulation for their parameters are in the intermediate position between the two types of darts. Combination type of insulation includes sprat balls. The outside cover is made up of fibrous material, and the inside cover is enamel. For example, wire PELSHO means: wire copper winding with insulation, seam and lacquer enamel.

As a conductor of leaks with heat-resistant varnish and coating with fiberglass, this marking is to avenge the letter “K”. This type of drotu, having become popular due to its high arrogance, is victorious for electric motors in pidio-transport mechanisms, including ship cranes.

Recut form

Winding darts have two forms of overcutting:

1. Round.
2. Rectangular.

A round cut of the dart victorious in various spheres. Such a wire may have high technical and electrical characteristics.

Diagrams of straight-cut cross-sections of darts are standardized. Such a wire is often used for transformer windings. The thickness of the straight drives reaches 5.9 mm, and the width is up to 14.5 mm.

Spivvіdshenie tsikh rozmіrіv can be different. And deakі nedolіki, scho vorazhayutsya zastosuvannі winding dartіv flat pererіzu. When it is wound on the bay, there is a great opportunity to damage the insulation, and also, with small cuts, it is visually important to cut the smaller side of the cut into the larger one.

In case of a winding, an important element is a coil of a conductor near the core. For the straining of the struma, the necessary resection of the drota is selected. Round drіt zasvychivayut vikoristovuєtsya for small vanity, and straight-cut drіt zastosovuyut for more high vanity.

Material strumovedchoї lived

Most of the winding wires are made from the following materials:

1. Mid.
2. Aluminium.

The middle rods for windings are folded to the greater part of all wires that are released. Stink mayut maly pitomy opir, I mean wag. Vartist medium darts temple.

In the rest of the hour, the replacement of the middle wires for the windings began to vikoristovuvaty aluminum wire, which significantly lay behind the rail, may be less varty, but may be more high-pittomy opir, it is equal to the middle conductor.

Markuvannya

For the recognition of the drota, it is necessary to mark the mark, as it means that the material lived that isolation.

• On the back of the letter there is a letter "P" for the mid dart, and means "provided".
• For the recognition of aluminum and medium darts, for example, the marking is the letter “A”, for example, PEVA.
• How the vein is crushed with alloy, what can be greater nursery opir, then the designation is additional letters, for example, HX - nichrome, M - manganin, Do - constantan.
• To identify a soft conductor, put the sign "M", for a hard one - "T". For example, wire PEMT - medium wire from hard darts, and wire PEMM - from soft darts.

Letters for identification of insulation

• EM - high quality polyvinyl enamel.
• EL - olive base.
• EV - high-comity polyvinyl acetate enamel.
• L - lavsan.
• Sh - natural seam.
• B - yarn for babies.
• Oh, one ball.
• C - fiberglass.
• ShK - capron.
• D - two balls.

How to mark the cost of the 2nd letter “P”, it means that the insulation is like a spit. Provid PPF equipment with insulation from the view of fluoroplastic sleeving.

For marking combined insulation, symbols should be in the order of the balls, starting from the inside. PELSHO - drіt medny, enamel on an oil basis and a single-ball suture braid.

Wimogi

1. Winding conductors are covered with equal insulation. Allowed at certain points of sweating up to the mark and size of the dart.
2. Drіt is transported in bays, drums and bobbins, fallow type of types and brands. The conductor in such packages can be wound evenly and narrowly, without twisting turns. The number of airborne dart in the bay or kotushtsі may be confirmed by the expansion and march of the dart.
3. Packings are to be packed with paper, the building is to protect the insulation from the door during the transportation time. The largest load of the box with a wire is not responsible for the load of 80 kg.
4. A label is applied to the drum of that coil from the designation of the picking plant, masi, standard size and brand of the wire, as well as other parameters.

How to choose winding rods for dvigun

The necessary wire for rewinding electric motors is subject to the improvement of the thermal stability class, the insulation ball, which is allowed, by those other powers.

The minimal tovshchina to the sphere of isolation is carried out by enamel conductors. Їх vikoristovuyut at the advanced vіdsotku zapovnennya groove under the hour of winding. The smooth surface of the insulation makes it easier to lay it in the grooves, and the small thickness when moving the heat transfer ensures protection from overheating.

The selection of enameled wires may be consistent with the same types of varnishes and retailers that are victorious in a particular business, or for these brands of varnishes, which the business can provide. Іsnuyut rozchinniki ta lacquers, yakі zdatnі zruynuvati enamel. And also, when heated up to 170 degrees, the insulation becomes plastic, which does not allow stasis for the windings of the rotors, which are wrapped with a large winding shvidkistyu.

The maximum thickness of the insulated ball can be used for winding with a combinable and fibrous ball. Її vikoristannya zaboronyaetsya for windings, scho in an aggressive human middle. For such purposes, it is necessary to add winding darts, equipped with glass insulation, and a small amount of insulation imposes a ring of winding darts on such darts. I want for thermostability droti with glass insulation suitable for similar winding classes. When attaching a winding dart, it is necessary to ensure that the dart of the same type of size should be deposited in the brand. When it comes to the repair of low-voltage electrical machines, the price of the cost is more than a part of the financial costs for the repair. At the link with cim, it is necessary to change the technical and economic factors of choice, so that the price of the technical parameters.
