Description
Technical field
The invention belongs to transformer load testing equipment field, especially a kind of transformer load test low-voltage-side adjustable short-circuit device.
Background technology
When transformer load is tested, need low-pressure side winding to have bigger through-current capability, common wire cannot meet four and connect
Requirement during line terminals short circuit, needs to carry out short circuit, at present when low-pressure side short circuit relatively frequently with low temperature with certain thickness copper bar
Structure is: clamp the both sides of four binding posts with two copper coins, and these two copper coin upper ends are clamped by multiple locking pliers.But should
Structure there is problems in that (1) copper bar size is changeless, and the transformator of different model must be used various sizes of copper
Row, causes unnecessary trouble；(2), during test, copper bar and low-pressure side line end need to be in close contact, and need with many when fixing
Individual locking pliers fastens；(3) locking pliers size is relatively big, is limited by low-pressure side line end space, there is certain barrier time fixing
Hinder；(4) fastening performance of locking pliers is very strong, and low-pressure side line end can be caused damage by misoperation, leaves hidden danger.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that rational in infrastructure, be applicable to the one of different size transformator
Plant transformer load test low-voltage-side adjustable short-circuit device.
The present invention adopts the technical scheme that:
A kind of transformer load test low-voltage-side adjustable short-circuit device, including four spaced binding posts, it is characterised in that:
All being set with a connecting seat on each described binding post, each two adjacent connection made upper end, seat upper end flanges are by flexible copper
Sheet turns on, and is respectively provided with the clamp module for clamping this side terminal in each connection seat.
And, opening is made in both sides, each described connection seat bottom face, and a horizontal groove is made in bottom surface, above this horizontal groove
Front inner wall and rear side inwall symmetry are embedded in an arc spring lamination, and the gap between these two arc spring laminations is used for accommodating described terminals
Son.
And, the horizontal cross-section of described flexible copper sheet is continuous bending type.
And, the horizontal cross-section of described flexible copper sheet is arc.
Advantages of the present invention and good effect be:
In the present invention, each of which in four binding posts of the low-pressure side of transformator is inlaid in a connecting seat, adjacent two companies
The upper end of joint chair is all turned on by flexible copper sheet, and above-mentioned flexible copper sheet can the most freely stretch, and is filled in connecting seat
Binding post is clamped by arc spring lamination, and the structure of above-mentioned flexible copper sheet is applicable to the step down side binding post of different spacing,
It is easily installed, dismantles and tests efficiently.

Son 2, the innovation of the present invention is: be all set with a connecting seat 3 on each described binding post, on each two adjacent connection seats
Hold made upper end flange 1 to be turned on by flexible copper sheet 4, in each connection seat, be respectively provided with the clamping for clamping this side terminal
Module.
In the present embodiment, opening 6 is made in both sides, each described connection seat bottom face, and a horizontal groove 8, this horizontal groove are made in bottom surface
Front inner wall and rear side inwall symmetry are embedded in an arc spring lamination 7, the gap between these two arc spring laminations and horizontal groove both sides
Bottom surface 9 be provided commonly for accommodating described binding post.In the present embodiment, the horizontal cross-section of described flexible copper sheet is continuous bending type.
The horizontal cross-section of described flexible copper sheet is arc.
In the present invention, each of which in four binding posts of the low-pressure side of transformator 5 is inlaid in a connecting seat, adjacent two
The upper end connecting seat is all turned on by flexible copper sheet, and above-mentioned flexible copper sheet can the most freely stretch, and connects institute in seat
Binding post is clamped by dress arc spring lamination, and the structure of above-mentioned flexible copper sheet is applicable to the transformer low voltage side terminal of different spacing
Son, it is simple to install, dismantle and test efficiently.
