Problems solved by technology
With such a structure, although the interlocking of the rear cabinet door can realize that the rear cabinet door cannot be opened when the grounding switch is in the open state, the grounding switch can still be opened and closed when the rear cabinet door is not closed. Anti-interlock function requirements, can not prevent misoperation, there are serious safety hazards

Embodiment Construction
[0017] In order to facilitate those skilled in the art to understand the technical solution of the present invention, the technical solution of the present invention will be further described in conjunction with the accompanying drawings.
[0018] Such as Figure 1 to Figure 4 As shown, the technical solution of the present invention is a high-voltage switch cabinet anti-interlock device, including a high-voltage switch cabinet 7 and an interlock device, the high-voltage switch cabinet includes a rear cabinet door 1, and the interlock device includes an interlock plate 5 and an interlock The locking piece 5 is fixed to the grounding switch shaft 8, and the grounding switch shaft 8 drives the interlocking piece 5 to rotate to realize normal interlocking. 5 is fixed away from the side of the rear cabinet door 1. The anti-interlocking device includes a horizontal slideway 6 installed on the top of the high-voltage switch cabinet 7. The horizontal slideway 6 is vertically installe...

The invention discloses an anti-interlocking device of a high voltage switch cabinet. The anti-interlocking device comprises a horizontal slideway mounted on the top of the high voltage switch cabinet. The horizontal slideway is mounted to be perpendicular to interlocking pieces. A vertical slide rod and a return spring are arranged in the horizontal slideway. The return spring is horizontally arranged on the end part of the vertical slide rod and the horizontal slideway away from the rear cabinet door. A horizontal stop rod is arranged on the bottom of the vertical slide rod. The horizontal stop rod is arranged on the side surface of the interlocking pieces and perpendicular to the interlocking pieces. A push rod is arranged on the top of the inner side surface of the rear cabinet door. The push rod is horizontally arranged and faces the vertical slide rod. According to the anti-interlocking device of the high voltage switch cabinet, anti-interlocking of the rear cabinet door plate can be reliably realized and the grounding switch be opened only when the rear cabinet door is closed so as to prevent mistaken operation and effectively prevent potential safety hazards caused by mistaken operation.
Description
technical field [0001] The invention belongs to the technical field of high-voltage switchgear components, and more specifically relates to an anti-interlocking device for a high-voltage switchgear. Background technique [0002] In the current power system, the rear cabinet door interlock of the high-voltage switchgear is mainly composed of the rear cabinet door panel, retainer, side plate, grounding switch shaft, and interlocking piece, and the rear cabinet door interlock is mainly rotated by operating the grounding switch shaft. Rotation, the rotation of the large shaft of the grounding switch drives the interlocking piece to rotate, that is, the interlocking piece turns from the vertical state inward to the horizontal state. When the rear cabinet door is closed, the rotating interlocking piece just snaps into the block Between the cabinet door panels, so as to achieve the purpose of interlocking the rear cabinet door panels. With such a structure, although the interlocki...
