Abstract
The utility model belongs to the technical field of electrical equipment and particularly relates to a multi-strand transposed conductor with multiple connected sections. The transposed conductor comprises naked copper flat wires, a film layer, an insulating layer and soldered joints; the naked copper flat wires of 2 to 4 wire gauges are connected into a copper flat wire via the soldered joints inthe narrow side direction; the film layer is applied outside the copper flat wire so as to form an enameled copper flat wire; a certain amount of enameled copper flat wires are arranged in two linesby wide side contact; the upper surface and the lower surface of the two lines of enameled copper flat wires change the same direction and the same position along the narrow side; and the insulating layer is wrapped outside each enameled copper flat wire. When applied to a oversize transformer, the utility model has the advantages of great reduction of load losses, temperature increase of windinghot spot, compact structure and simpler and more convenient coiling, thereby improving the safety and reliability; and a transformer winding made of the transposed conductor of the utility model has the advantages that the electrical performance can be improved, the capacitance is distributed more uniformly, and the space is saved, thereby facilitating miniaturization of products, increasing the mechanical strength, balancing the ampere turn and enhancing the anti-shortcircuit capability of the products.
Description
Technical field
The utility model belongs to the electric equipment technical field, is specifically related to a kind of many radicals more piece transposed conductor that joins.
Background technology
So-called transposed conductor is meant that the enameling copper strap wire that is generally 5～71 odd number roots with certain radical is combined into two row that wide face is in contact with one another, on request on two row enamelled wires and below do the same transposition that turns to along leptoprosopy, and make multilayer with electrician's insulating paper strip and closely hold composition continuously, be exclusively used in and make big capacity high voltage transformer or other electrical equipment winding.At present, the wire gauge of every of this transposed conductor enameling copper strap wire (thick, the wide specification of line) is the same.The plumb joint of transposed conductor enameling copper strap wire seldom and staggers naturally mutually, and this is to guarantee that the electric property of transposed conductor is desired.
Summary of the invention
The purpose of this utility model is to provide a kind of many radicals more piece transposed conductor that joins, and is used to make the Transformer Winding that property requires, and carries the needs of electricity to satisfy the big capacity of ultra high voltage.
The many radicals more piece that the utility model proposes transposed conductor that joins, comprise bare copper flat wire 1, paint film layer 2, insulating barrier 3, plumb joint 4, the bare copper flat wire 1 of 2～4 kinds of wire gauges connects into a copper strap wire by plumb joint 4 in the leptoprosopy direction, copper strap wire is coated with paint film layer 2 outward, constitute enameling copper strap wire, the enameling copper strap wire of some is lined up two row by wide contact, on two row enameling copper strap wires and below do the same transposition that turns to along leptoprosopy, its outer insulating barrier 3 that holds.
In the utility model, mode or the spiral mode of staggering of intersecting adopted in the distribution of plumb joint 4.Described intersection stagger mode be distance between the plumb joint of adjacent two enameling copper strap wires greater than 500mm, the weld zone length of each sections is less than 2000mm; Described spiral mode is for being divided into n root enameling copper strap wire the m group, and the m of an every group of enameling copper strap wire plumb joint all is arranged in order, and the distance between adjacent two plumb joints 4 is 400mm.
In the utility model, because every enameling copper strap wire has multiple wire gauge, so just increased the plumb joint of transposed conductor greatly, its quantity reaches n * (m-1) individual (n is bare copper flat wire 1 radical in parallel, and m is a hop count).If by industry standard JB6758 requirement, the plumb joint of adjacent two enameling copper strap wires will keep more than the 500mm,, leak electricity between anti-principal vertical line to guarantee the wire insulation distance.
The length of the utility model weld zone can be limited within the 1000mm, makes the plumb joint that faces mutually between the different wire gauges of two copper strap wires keep satisfactory distance again, thereby guarantees the electric property of transposed conductor.
The utility model manufacture method is as follows, when the m nodel line rule of the n root enameling copper strap wire of transposed conductor are joined, its plumb joint 4 intersects the mode of staggering mutually by mode shown in Figure 3, make the distance 500mm at least between the plumb joint of adjacent two enameling copper strap wires, the weld zone length of a sections is no more than 2000mm.
The plumb joint of each sections weld zone of enameling copper strap wire also can be by spiral arrangement, it is one group promptly with 5 enameling copper strap wires, (example) is divided into the n/5 group to copper strap wire, and each 5 plumb joint organizing enameling copper strap wire all is arranged in order, and the distance between adjacent two plumb joints is 400mm.This weld zone length is 2000mm like this.Plumb joint by the plane width of cloth to expansion as shown in Figure 2.
The beneficial effects of the utility model are:
After oversize transformer adopts the utility model, can significantly reduce load loss, winding focus and heat up, make that structure is compact more, coiling is easier, thereby security reliability is improved.Both satisfy the electrical characteristic requirement of Transformer Winding, and made plumb joint that suitable length is arranged again, guaranteed the weld strength requirement.By the Transformer Winding that the utility model transposed conductor is made, can improve the equipment electric property, make capacitance profile even, conserve space helps the miniaturization of product; Simultaneously can increase mechanical strength, make ampere-turn equilibrium, strengthen the anti-short circuit capability of product.
Description of drawings
Fig. 1 is the utility model cross-sectional illustration.
Fig. 2 is that the plane width of cloth that the plumb joint distribution of a weld zone is arranged in a spiral manner illustrates to expansion.
Fig. 3 is that the plane width of cloth that the plumb joint distribution of a weld zone is arranged with interleaved mode illustrates to expansion.
Number in the figure: 1 is bare copper flat wire, and 2 is paint film layer, and 3 is insulating barrier, and 4 is plumb joint.
Embodiment
Further specify the utility model in conjunction with the accompanying drawings below by embodiment.
Embodiment 1: certain transformer, its transposed conductor will be formed with 25 enameling copper strap wires, and the end to end composition of lead of every copper strap wire requirement multiple (n kind) different wire gauges, supposes n=4.Then in the middle of this transposed conductor 3 plumb joint zones are arranged, there are 75 plumb joints in whole plumb joint zone.Thickness * width requirement that its 4 kinds of wire gauges are pressed copper strap wire is as follows: 1.18 * 7.3 (mm), 1.4 * 7.3 (mm), 1.6 * 7.3 (mm), 1.4 * 7.3 (mm).When making this transposed conductor, distribute by interleaved mode arrangement design plumb joint shown in Figure 2, can make the distance that staggers between the plumb joint of adjacent two copper strap wires be 500mm, each plumb joint length is 60mm, to guarantee its weld strength, each weld zone length is 1000mm.All the other technologies are identical with routine.The transposed conductor solder joint of Zhi Zuoing is intensive thus, but the weld zone insulation property are good, and is perfectly safe, guarantees the safe handling of winding.
