Abstract
The invention relates to a transformer load test low-voltage-side adjustable short-circuit device. A connection seat is sleeved on each connection terminal. An upper-end convex plate manufactured at the upper ends of every two adjacent connection seats is switched on through a telescopic copper plate. A clamping module used for clamping a connection terminal of a corresponding side is arranged in each base. In the transformer load test low-voltage-side adjustable short-circuit device, each of the four connection terminals at the low-voltage side of the transformer is embedded in a corresponding base and the upper ends of every two adjacent bases are both switched on through the telescopic copper plate. The telescopic copper plates are capable of expanding and contracting freely in a specific range. Arc shrapnels in the bases clamp tightly the connection terminals. The telescopic copper-plate structure is applicable to transformer low-voltage-side connection terminals of different distances so that installation, dismounting and rapid experiment are facilitated.
Description
Technical field
The invention belongs to transformer load testing equipment field, the adjustable short-circuit device of especially a kind of transformer load test low-pressure side.
Background technology
When transformer load is tested, need low-pressure side winding to have larger through-current capability, requirement when common wire cannot meet four connection terminal short circuits, need to carry out short circuit with certain thickness copper bar, when low-pressure side short circuit, more often adopt low temperature structure to be at present: the both sides of clamping four connection terminals with two copper coins, these two copper coin upper ends clamp by a plurality of locking pliers.But there is following problem in this structure: (1) copper bar size is changeless, must adopt the copper bar of different size to the transformer of different model, causes unnecessary trouble; (2), while testing, copper bar and low-pressure side line end need close contact, fixedly time, need to carry out fastening with a plurality of locking pliers; (3) locking pliers size is larger, is subject to the restriction in low-pressure side line end space, has certain obstacle in the time of fixedly; (4) the fastening performance of locking pliers is very strong, and misoperation can cause damage to low-pressure side line end, leaves hidden danger.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide rational in infrastructure, applicable to a kind of transformer load of different size transformer, test the adjustable short-circuit device of low-pressure side.
The technical scheme that the present invention takes is:
The adjustable short-circuit device of a kind of transformer load test low-pressure side, comprise four spaced connection terminals, it is characterized in that: described in each, on connection terminal, be all set with a connecting seat, each adjacent made upper end, two Connection Block upper ends flange, by flexible copper sheet conducting, is all provided for clamping the clamp module of this side terminal in each base.
And opening is made in base end face both sides described in each, a horizontal groove is made in bottom surface, this horizontal groove top front side inwall and symmetrical setting-in one arc spring lamination of rear side inwall, the gap between these two arc spring laminations is used for holding described connection terminal.
And the horizontal section of described flexible copper sheet is continuous bending type.
And the horizontal section of described flexible copper sheet is arc.
Advantage of the present invention and good effect are:
In the present invention, each in four connection terminals of low-pressure side of transformer is all inlaid in a base, the upper end of adjacent two bases is all by flexible copper sheet conducting, above-mentioned flexible copper sheet is free-extension within the specific limits, in base, the arc spring lamination that fills clamps connection terminal, the structure of above-mentioned flexible copper sheet, applicable to the step down side connection terminal of different spacing, is convenient to install, is dismantled and test efficiently.
