Abstract

The utility model discloses a lead structure for a dry type transformer. The lead structure comprises a connector body; the end part of the connector body is provided with a packing groove; a conducting wire is located in the packing groove; and a welding flux is filled in the packing groove. The lead structure for the dry type transformer has the advantages that on one hand, the welding quality is ensured, and the phenomenon that crystal grains are coarse and massive due to quick cooling after being heated to be close to the melting point during welding is effectively reduced; and on the other hand, the generation of cracks and burrs at a welded part is reduced, so that the circumstances that the welded part is subjected to point discharge during use are avoided, the partial discharge quantity is effectively reduced, and the service life of the transformer is prolonged.

Description

A kind of pin configuration of dry-type transformer
Technical field
The utility model belongs to the power transformer technical field, particularly a kind of pin configuration of dry-type transformer.
Background technology
High-voltage connection copperhead welding is widely used on the dry-type transformer, is called the patent of " the continuous productive process device of transformer high-low pressure wire bonds and assembling " like the disclosed key name of utility model patent of Chinese patent numbers 200920199794.3.This patent discloses a kind of transformer high-low pressure wire bonds and assembly line flow process device; It comprises that the low-voltage lead welding, the high-voltage connection that are used for transformer are fixed, high-voltage connection welds and the work roll table of high-low pressure lead wire insulation operation; Be used to place transformer a plurality of pallets, be used to transport the transport vehicle of transformer, the boom hoisting that can transformer be sling between work roll table and transport vehicle; Wherein the pallet sliding fit is on work roll table; Transport vehicle is located at the next door of work roll table; The device of slinging is arranged on that working roll is understood and the top of transport vehicle, but above-mentioned patented technology is to use the operating efficiency that could embody itself down and process advantage easily producing in batches, and but under many specifications, output is few and the work-yard is not enough situation; The operability of above-mentioned patent will reduce; Thereby for satisfy in many specifications, output is few and the work-yard is not enough, as realizes the welding of high-voltage connection copperhead under the situation about making an experiment, and need design a kind of pin configuration of novel dry-type transformer.
The utility model content
The purpose of the utility model is to provide a kind of and improves the quality of welding, effectively reduces the pin configuration that welding position crystal grain is thick, reduce the dry-type transformer of crackle and burr; Comprise joint body; Packing groove is offered in said joint body end; Lead is positioned at said packing groove, fills scolder in the said packing groove.
Preferably, the material of said joint body is a copper.
Preferably, said scolder be distributed in said lead around.
Preferably, said packing groove is shaped as cuboid.
Behind the employing said structure, the utlity model has following beneficial effect: guaranteed the quality of welding on the one hand, be heated near cooling fast behind the fusing point when effectively reducing, caused the thick phenomenon of crystal grain owing to welding; Reduce welding position crackle and burr on the other hand and produce, thereby avoid this welding position in use the situation of point discharge to occur, effectively reduce partial discharge quantity, increase the useful life of transformer.
Description of drawings
Fig. 1 is the structure chart of the utility model;
Fig. 2 be the utility model Fig. 1 front view;
Among the figure: 1-scolder 1; The 2-joint body; The 3-lead; The 4-packing groove.
Embodiment
Come the utility model is done further detailed explanation below in conjunction with accompanying drawing and specific embodiment.
Referring to Fig. 1-shown in Figure 2, the utility model provides a kind of pin configuration of dry-type transformer, comprises joint body 2, and packing groove 4 is offered in said joint body 2 ends, and lead 3 is positioned at said packing groove 4, fills scolders 1 in the said packing groove 4; The material of said joint body 2 is a copper; Said scolder 1 be distributed in said lead 3 around; Said packing groove 4 be shaped as cuboid.
The utility model implementation procedure is: lead 3 is placed in the packing groove 4; Then with scolder 1 be filled in packing groove 4 inside conductors 3 around; Weld then, after welding completion, also cooperate and adopt cooling indirectly: the container with a filled with water is under water gradually with copper sleeve body 2 from the bottom to top, and this plumb joint structure and method have been guaranteed the quality of welding; Be heated to when effectively reducing near cooling fast behind the fusing point owing to welding; Cause the thick phenomenon of crystal grain, reduce crackle and burr and produce, thereby also avoid this position to occur the situation of point discharge in use.
The foregoing description is the utility model preferred implementation; But the execution mode of the utility model is not restricted to the described embodiments; And other any do not deviate from change, the modification done under spirit and the principle of the utility model, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection range of the utility model.
