Abstract
The utility model relates to a novel low-voltage short-circuiting copper bar, which comprises double copper bars and a paper clapboard arranged between the double copper bars, wherein clapboards and copper plates are alternatively arranged between the double copper bars, and are fixed tightly; the copper plates are effectively contacted with the double copper bars; the clapboards are made of an insulating material; and the edges and corners of the clapboards and the copper plates are smooth. In the novel low-voltage short-circuiting copper bar, two short-circuiting copper plates are arranged between double low-voltage copper bars, so that a small loop is formed between the double copper bars, and ring current is reduced.
Description
Technical field
The utility model belongs to transformer manufacture technology, is specifically related to a kind of novel low pressure short circuit copper bar.
Background technology
1000KV step-up transformer low-voltage coil electric current is big; Lead-in wire connects uses two copper bar structures; In order to reduce the kelvin effect of two copper bars, between two copper bars, add partition, two copper bars are connected to form the loop through winding protruding head; Simultaneously the magnetic leakage flux of copper bar region is big, causes between two copper bars circulation big.
Summary of the invention
To the problems referred to above, the utility model provides a kind of novel low pressure short circuit copper bar that can reduce circulation between two copper bars.
The utility model adopts following technical scheme: comprises two copper bars and is located at the dividing plate between two copper bars, between two copper bars, alternately be provided with dividing plate and copper coin, and fixed, copper coin well effectively contacts with two copper bars; Said dividing plate is an insulating material, and the corner angle of said dividing plate and copper coin are smooth.
Further, the thickness of this copper coin is identical with insulation thickness between two copper bars, make copper coin can with the contacting fully of two copper bars.
Dividing plate and copper coin can be located between two copper bars through the mode of bolt or welding, and copper coin just can contact with two copper bars fully like this, thereby realize the short circuit of two copper bars, form the loop, reduce circulation.
The beneficial effect of the utility model is: the utility model forms than minor loop through between the two copper bars of low pressure, adding the copper coin that the short circuit effect is played at two places, making between two copper bars, has reduced circulation.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Among the figure: 1, two copper bars, 2, dividing plate, 3, copper coin.
Embodiment
A kind of novel low pressure short circuit copper bar comprises two copper bars 1 and is located at the dividing plate 2 between two copper bars that dividing plate 2 is an insulating material, and dividing plate 2 adopts partition.Between two copper bars, alternately be provided with insulating paper dividing plate 2 and short circuit copper coin 3, every separated 500mm connects with the short circuit copper coin between two copper bars, and fixed, and copper coin is well effectively contacted with two copper bars.Wherein, the thickness of copper coin 3 is identical with insulation thickness between two copper bars 1, and the corner angle of said partition 2 and copper coin 3 are smooth.This copper coin 3 is located between two copper bars through bolt, thereby the short circuit of the two copper bars 1 of realization forms the loop.
