Abstract

The invention provides a switch cabinet and a multi-triggering interlocking device thereof. The switch cabinet multi-triggering interlocking device comprises a box and a locking block on a cable room door, wherein the locking block is provided with a limiting hole, a rotating piece and an elastic reset piece used for driving the rotating piece to reset are arranged in the box, the rotating piece comprises a locking portion which can be rotationally clamped into the limiting hole of the locking block, a stopping structure used for controlling the rotation of the rotating piece is also arranged in the box, the stopping structure comprises an operating arm connected with a plurality of triggering components, the rotating piece comprises a locking position, and when in the locking position, the locking portion of the rotating piece is clamped into the limiting hole. According to the switch cabinet interlocking device of the invention, the triggering components can control the opening of the cable room door via the multi-triggering interlocking device; the switch cabinet interlocking device adopts the pure mechanical structure, and is simple in structure, relatively low in cost, high in reliability and good in protection performance.

Description

technical field [0001] The invention relates to the technical field of electric power products, in particular to a switch cabinet and a multi-trigger interlocking device thereof. Background technique [0002] When the high-voltage switchgear is normally powered, the grounding switch in the high-voltage switchgear is in the open state. When the high-voltage switchgear needs to be repaired, in order to prevent the maintenance personnel from opening the live high-voltage switchgear, or to prevent the high-voltage switchgear from being disconnected. The residual charge on the equipment will cause harm to the maintenance personnel. To ensure the personal safety of the maintenance personnel, when performing maintenance on electrical equipment, the grounding switch must be closed for grounding to each equipment that may be powered and the equipment that may generate induced voltage. In order to prevent maintenance personnel from accidentally entering the charged gap when opening th...
