Abstract
The utility model discloses a central-positioned high-voltage switch cabinet, which comprises a cabinet body and a grounding switch, wherein the cabinet body is internally provided with a copper bar, an auxiliary cabinet is arranged beside the cabinet body, the grounding switch is arranged in the auxiliary cabinet, the copper bar in the cabinet body is provided with a branch copper bar, the branch copper bar is connected to the grounding switch arranged in the auxiliary cabinet through a connecting sleeve, and an outgoing line end of the copper bar in the cabinet body is connected to a cable independently. According to the utility model, the auxiliary cabinet is additionally arranged beside the cabinet body, the grounding switch is arranged in the auxiliary cabinet, the copper bar is transferred to the adjacent auxiliary cabinet and connected to the grounding switch, so that the space is sufficient when the grounding switch is operated so as to ensure the safe distance, thereby reducing the hidden danger of accident occurrence.
Description
Technical field
The utility model relates to high-voltage board, relates in particular to a kind of central-positioned high-voltage switch cabinet.
Background technology
At present, 10KV central-positioned high-voltage switch cabinet outgoing line cabinet, is as shown in Figure 1 under normal circumstances, and in the middle of earthed switch is installed to, on mounting panel, the position of rotation of the edge of a knife is towards Gui Hou cable vault.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 safety operation of ground cutter.
When the load of high-voltage terminal cabinet is larger, when electric current is larger, corresponding used copper bar specification 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 ensureing that safe distance is enough, space, cable vault has taken, and does not have enough spaces to remove to install additional earthed switch.If add isolating switch, due to limited space, safe distance is inadequate, easily causes security incident.
Utility model content
The purpose of this utility model is to provide a kind of central-positioned high-voltage switch cabinet, can make earthed switch have enough spaces, minimizing accident generation hidden danger.
The utility model adopts following technical proposals: a kind of central-positioned high-voltage switch cabinet, include cabinet, earthed switch, copper bar is installed in cabinet, described cabinet side is provided with auxiliary cabinet, described earthed switch is arranged in auxiliary cabinet, on copper bar in described cabinet, be provided with branch's copper bar, this branch's copper bar accesses the earthed switch arranging in auxiliary cabinet by joint sleeve, the independent stube cable of copper bar leading-out terminal in described cabinet.
Between described cabinet and auxiliary cabinet, be provided with intercommunicating pore, described joint sleeve is arranged on intercommunicating pore place.
The utility model increases an auxiliary cabinet on cabinet side, earthed switch is arranged in auxiliary cabinet, and copper bar is transferred in adjacent auxiliary cabinet and connects earthed switch, and earthed switch is changed to left operation by original right operation.There are when operational grounding switch so enough spaces to ensure safe distance, thereby reduced accident generation hidden danger.In cabinet, also there are enough spaces can stube cable.
Brief description of the drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
Embodiment
As shown in Figure 2, a kind of central-positioned high-voltage switch cabinet, include cabinet 1, earthed switch 3, in cabinet, 1 is provided with copper bar, described cabinet 1 is other is provided with auxiliary cabinet 2, and described earthed switch 3 is arranged in auxiliary cabinet, on the copper bar in described cabinet 1, is provided with branch's copper bar 5, this branch's copper bar 5 accesses the earthed switch 3 arranging in auxiliary cabinet 2, the independent stube cable of copper bar leading-out terminal in described cabinet by joint sleeve 4.
Between described cabinet 1 and auxiliary cabinet 2, be provided with intercommunicating pore, described joint sleeve 4 is arranged on intercommunicating pore place.
The utility model increases an auxiliary cabinet on cabinet side, earthed switch is arranged in auxiliary cabinet, and copper bar is transferred in adjacent auxiliary cabinet and connects earthed switch.Earthed switch is changed to left operation by original right operation.There are when operational grounding switch so enough spaces to ensure safe distance, thereby reduced accident generation hidden danger.In cabinet, also there are enough spaces can stube cable.
Claims (2)
