Abstract
The invention discloses a kind of arrangement of transformer lead, disclose a kind of arrangement of transformer high-voltage tap lead especially.The arrangement of this transformer high-voltage tap lead, comprise sub-connecting switch of transformer, high-voltage connection folder, high-voltage tap lead, it is characterized in that: the high-voltage tap lead of this transformer A, B phase winding is arranged in the front side outlet of device body, and the high-voltage tap lead of C phase winding is arranged in the rear side outlet of device body.Beneficial effect of the present invention: adopt both sides, device body front and back to go out the mode of high-voltage connection, can reduce the high-voltage connection bundle in the one-sided overall height dimension of device body, be convenient to guarantee the insulation distance between tap lead, be beneficial to heat radiation, reduced the difference in height that produces when tap lead is connected with sub-connecting switch of transformer simultaneously.Can reduce the transformer-cabinet height, reduce material usage, save a large amount of transformer oil and copper lead-in wire, be beneficial to the short and small high-power transformer of design height size.
Description
(1) technical field
The present invention relates to a kind of arrangement of transformer lead, particularly a kind of arrangement of transformer high-voltage tap lead.
(2) background technology
Present stage, the high-voltage tap lead of 35～220kV level power transformer is arranged at the homonymy of transformer body, the power transformer that this situation is more to the high-voltage tap gear, owing to decompose lead-in wire bundle broad, for guaranteeing the safe insulation distance between A, B, C three-phase tap lead, need to increase the transformer-cabinet size, increased material consumption and take up room.Be easy to generate when transformer out-phase tap lead connects with sub-connecting switch of transformer and produce cross one another phenomenon, make the insulation distance between the out-phase tap lead too small, cause the electric property of transformer to descend.
(3) summary of the invention
The present invention is in order to remedy the deficiencies in the prior art, and a kind of arrangement of transformer high-voltage tap lead attractive in appearance simple in structure, easy to operate, safe and reliable, linear is provided.
The present invention is achieved through the following technical solutions:
A kind of arrangement of transformer high-voltage tap lead, comprise sub-connecting switch of transformer, high-voltage connection folder, high-voltage tap lead, it is characterized in that: the high-voltage tap lead of this transformer A, B phase winding is arranged in the front side outlet of device body, and the high-voltage tap lead of C phase winding is arranged in the rear side outlet of device body.
Beneficial effect of the present invention: adopt both sides, device body front and back to go out the mode of high-voltage connection, can reduce the high-voltage connection bundle in the one-sided overall height dimension of device body, be convenient to guarantee the insulation distance between tap lead, be beneficial to heat radiation, reduced the difference in height that produces when tap lead is connected with sub-connecting switch of transformer simultaneously.Can reduce the transformer-cabinet height, reduce material usage, save a large amount of transformer oil and copper lead-in wire, be beneficial to the short and small high-power transformer of design height size.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is the front view of traditional high-voltage tap lead arrangement;
Fig. 2 is the front view of arrangement of the present invention;
Fig. 3 is the rearview of arrangement of the present invention.
Among the figure: 1 sub-connecting switch of transformer, 2 high-voltage tap leads folder, 3 high-voltage tap leads.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises sub-connecting switch of transformer 1, high-voltage tap lead folder 2, high-voltage tap lead 3, it is characterized in that: the high-voltage tap lead 2 of this transformer A, B phase winding is arranged in the front side outlet of device body, and the high-voltage tap lead 2 of C phase winding is arranged in the rear side outlet of device body.Adopt both sides, device body front and back to go out the mode of high-voltage connection, can reduce the high-voltage connection bundle in the one-sided overall height dimension of device body, be convenient to guarantee the insulation distance between tap lead, be beneficial to heat radiation, reduced the difference in height that produces when tap lead is connected with sub-connecting switch of transformer simultaneously.Can reduce the transformer-cabinet height, reduce material usage, save a large amount of transformer oil and copper lead-in wire, be beneficial to the short and small high-power transformer of design height size.Adopt the mode of device height, the wiring of low pressure both sides, produce the cross one another phenomenon of out-phase tap lead in the time of can effectively avoiding tap lead to be connected with sub-connecting switch of transformer, reduce the Electric Field Distribution between the out-phase tap lead, guarantee the safe insulation distance of tap lead, the difference in height of generation when reducing tap lead simultaneously and being connected with sub-connecting switch of transformer.
Claims (1)
1. the arrangement of a transformer high-voltage tap lead, comprise sub-connecting switch of transformer (1), high-voltage tap lead folder (2), high-voltage tap lead (3), it is characterized in that: the high-voltage tap lead (2) of this transformer A, B phase winding is arranged in the front side outlet of device body, and the high-voltage tap lead of C phase winding (2) is arranged in the rear side outlet of device body.
