Abstract
The utility model discloses a heavy-current central-positioned high tension switchgear which comprises a cabinet. A zero-sequence current transformer is mounted in the cabinet, an auxiliary cabinet is arranged beside the cabinet, and the wire outlet end of a copper bar of the zero-sequence current transformer is connected into the auxiliary cabinet and independently connected with a cable. According to the utility model, a sufficient spatial safety distance is ensured, hidden troubles are reduced, and convenience is provided for installation, operation and maintenance.
Description
Technical field
The utility model relates to high-tension switch cabinet, relates in particular to a kind of large electric current central-positioned high-voltage switch cabinet.
Background technology
At present, in the central-positioned high-voltage switch cabinet outgoing line cabinet of 10KV, zero-sequence transformer is installed on bottom plate of switch cabinet.This mounting means is applicable to the mode of cable vault's cable outlet, and electric current is little conventionally, and copper bar specification used is little, has enough safe spaces to carry out the installation of cable.
But when the load of high-voltage terminal cabinet is larger, when electric current is larger, the specification of corresponding used copper bar and cable also can increase.For example vacuum circuit-breaker is 3150A electric current, and leading-out terminal dropcable is 4 of every phases, totally 12 cables.In the situation that guaranteeing that safe distance is enough, space, cable vault has taken, and does not have enough spaces to remove to install zero-sequence transformer and installing cables.
Utility model content
The purpose of this utility model is to provide a kind of large electric current central-positioned high-voltage switch cabinet, can, in the situation that guaranteeing that safe distance is enough, have sufficient space installing cables.
The utility model adopts following technical proposals: a kind of large electric current central-positioned high-voltage switch cabinet, include cabinet, zero sequence current mutual inductor is installed in cabinet, described cabinet side is provided with auxiliary cabinet, the copper bar leading-out terminal of described zero sequence current mutual inductor accesses in auxiliary cabinet, the described independent stube cable of copper bar leading-out terminal.
The utility model increases an auxiliary cabinet on existing cabinet side, copper bar is transferred in adjacent auxiliary cabinet, for independent stube cable.So not only guarantee enough space safety distances, reduced accident generation hidden danger, and facilitated fitting operation and maintenance.
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 large electric current central-positioned high-voltage switch cabinet, include cabinet 1, vacuum circuit-breaker 3, current transformer 4, earthed switch 5, lightning arrester 6, charged display device 7 are installed in cabinet 1, described cabinet 1 side is provided with auxiliary cabinet 2, the copper bar leading-out terminal 8 of zero sequence current mutual inductor 9 accesses in auxiliary cabinet 2, the described independent stube cable of copper bar leading-out terminal 8.
The utility model has not only guaranteed enough space safety distances, has reduced accident generation hidden danger, and facilitates fitting operation and maintenance.
Claims (1)
1. a large electric current central-positioned high-voltage switch cabinet, include cabinet, zero sequence current mutual inductor is installed in cabinet, it is characterized in that: described cabinet side is provided with auxiliary cabinet, the copper bar leading-out terminal of described zero sequence current mutual inductor accesses in auxiliary cabinet, the described independent stube cable of copper bar leading-out terminal.
