Abstract
The utility model relates to a fixed structure for the high tension lead and the tapping switch of a transformer. The fixed structure comprises a high tension lead which is peripherally provided a paper insulator and a tapping switch which is provided with a connecting rack. The fixed structure is characterized in that the connecting rack made from insulation material is provided a plurality of thin-wall copper sleeves side by side; and the joint of each high tension lead is tightly inserted in the inner wall of a corresponding thin-wall copper sleeve. As a high tension paper covered round lead does not need to be wound, the fixed structure omits a nut and a bolt; when in connection, the thin-wall copper sleeve is tightly connected with the high tension lead conveniently only by outside force. Furthermore, as the thin-wall copper sleeve can be produced in batch, thereby greatly shortening the assembly time, improving the work efficiency and being good for ensuring the insulating strength of the transformer body.
Description
[technical field]
The utility model belongs to a kind of oil immersion-type distribution transformer, especially relates to the fixed structure of a kind of oil immersion-type distribution transformer high-voltage connection and shunting switch.
[background technology]
The structure of oil immersion-type distribution transformer comprises fuel tank, and the device body is fixed in the fuel tank.The high pressure winding of device body divides wiring to draw the back from coil and connects with high-voltage tap changer.Before the utility model was made, common connecting mode was that nut type connects, and took all of the end of lead-in wire around a circle at high-voltage paper earlier that is:, then snare was located on the corresponding double-screw bolt of shunting switch link, utilized the nut fastening force to realize connecting.This draw bail existing problems are: during operation, need take all of the end of lead-in wire around a circle at high-voltage paper, make trouble, complex procedures efficient is low, installation time is long, particularly prolong the aerial time of staying of transformer body, and diminished the dielectric strength of transformer.
[summary of the invention]
For overcoming the prior art above shortcomings, the utility model aims to provide the fixed structure of a kind of transformer high-voltage lead-in wire and shunting switch, after adopting this syndeton, can realize expeditiously that high-voltage paper takes all of lead-in wire and being connected of shunting switch, simple, the easy to operate efficient height of operation also helps the dielectric strength of guaranteeing transformer.
For achieving the above object, the utility model has adopted following technical scheme:
The fixed structure of this transformer high-voltage lead-in wire and shunting switch, comprise high-voltage connection and shunting switch, the high-voltage connection periphery is provided with paper insulation, shunting switch comprises a link, it is characterized in that: be provided with many thin-walled copper sleeves on the link that insulating material is made side by side, the pigtail splice of every high-voltage connection tightly is inserted between the inwall of a corresponding thin-walled copper sleeve.
Beneficial effect: lead-in wire need not be looped because high-voltage paper takes all of, and has omitted nut and double-screw bolt, during connection, only need use external force, and thin-walled copper sleeve and high-voltage connection are tightly linked together.Moreover, because the thin-walled copper sleeve can be made production in batch, greatly shortened installation time, improved operating efficiency, help guaranteeing the dielectric strength of device body.
[description of drawings]
Fig. 1 is the broken section structural representation of an embodiment of the utility model.
Among the figure: link 1, thin-walled copper sleeve 2, paper insulation 3, high-voltage connection 4, pigtail splice 5.
[embodiment]
Referring to Fig. 1.The fixed structure of this transformer high-voltage lead-in wire 4 and shunting switch, comprise high-voltage connection 4 and shunting switch, the periphery of high-voltage connection 4 is provided with paper insulation 3, shunting switch comprises a link 1, be provided with many thin-walled copper sleeves 2 on the link 1 that insulating material is made side by side, the pigtail splice 5 of every high-voltage connection 4 tightly is inserted between the inwall of a corresponding thin-walled copper sleeve 2.
During operation, earlier pigtail splice 5 is inserted in the corresponding thin-walled copper sleeve 2, then, get final product with the clamp chucking.
