Abstract
The utility model discloses two adjacent high-voltage cabinets, comprising a first high-voltage cabinet and a second high-voltage cabinet which are adjacent to each other, wherein the second high-voltage cabinet is internally provided with a zero-sequence current transformer, the second high-voltage cabinet is an outlet cabinet, and a three-phase cable penetrates through the zero-sequence current transformer and is connected to an inlet end in the first high-voltage cabinet and an outlet end in the second high-voltage cabinet. According to the utility model, the two adjacent high-voltage cabinets are connected through the three-phase cable, can easily meet a requirement that the outlet cabinet is attached with the zero-sequence current transformer, and also can meet requirements of power supply and distribution loads and requirements of the safety performance.
Description
Technical field
The utility model relates to high-voltage board, relates in particular to a kind of two adjacent high-voltage boards.
Background technology
At present, two adjacent high-voltage boards should adopt copper bar to carry out the connection of two cabinets under normal circumstances, not only elegant in appearance, and ampacity is identical, easy for installation, more have enough safe spaces.But, if wherein a high-voltage board is outgoing line cabinet, and with zero sequence current mutual inductor, can not adopt copper bar to connect, because the aperture of zero-sequence transformer can not meet passing of three-phase copper bar, and zero sequence current mutual inductor is due to the consideration of distribution electric current secure context, can not cancel again, will there is potential safety hazard if cancelled.
Utility model content
The purpose of this utility model is to provide a kind of two adjacent high-voltage boards, can meet the requirement that zero sequence current mutual inductor is installed, and has met again safety requirements.
The utility model adopts following technical proposals: a kind of two adjacent high-voltage boards, include the first high-voltage board and second high-voltage board of adjacent installation, in the second described high-voltage board, be provided with zero sequence current mutual inductor, the second described high-voltage board is outgoing line cabinet, threephase cable passes zero sequence current mutual inductor, the end of incoming cables in connection the first high-voltage board and the leading-out terminal in the second high-voltage board.
The utility model connects two adjacent high-voltage boards by threephase cable, can meet easily the requirement of the subsidiary zero sequence current mutual inductor of outgoing line cabinet, can meet again the needs for distribution load needs and security performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model discloses a kind of two adjacent high-voltage boards, i.e. the first high-voltage board 1 and the second high-voltage board 2, in the second described high-voltage board 2, be provided with zero sequence current mutual inductor 3, the second described high-voltage board 2 is outgoing line cabinet, threephase cable 4 passes zero sequence current mutual inductor 3, the end of incoming cables in connection the first high-voltage board 1 and the leading-out terminal in the second high-voltage board 2.The utility model connects two adjacent high-voltage boards by threephase cable, can meet easily the requirement of the subsidiary zero sequence current mutual inductor of outgoing line cabinet, can meet again the needs for distribution load needs and security performance.
Claims (1)
1. two adjacent high-voltage boards, include the first high-voltage board and second high-voltage board of adjacent installation, it is characterized in that: in the second described high-voltage board, be provided with zero sequence current mutual inductor, the second described high-voltage board is outgoing line cabinet, threephase cable passes zero sequence current mutual inductor, the end of incoming cables in connection the first high-voltage board and the leading-out terminal in the second high-voltage board.
