Isolating switch and grounding witch operating system

Abstract

The invention relates to an isolating switch and grounding witch operating system comprising a cabinet body and a cabinet door. The cabinet body is provided with an isolating switch, a grounding switch and an operating mechanism inside. The isolating switch includes a switch blade and a static contact which are hinged and fixed together. The operating mechanism includes an operating rod which is in linkage fit with an isolating shaft through a first connecting rod mechanism. The isolating shaft is equipped with a second connecting rod mechanism which is in linkage fit with the switch blade. The switch blade has a first position in which the switch blade contacts the static contact and a second position in which the switch blade contacts the grounding switch. The first connecting rod mechanism is provided with a door locking mechanism. When the switch blade is in the first position, the door locking mechanism locks the cabinet door and drives the switch blade to contact the static contact or be grounded through the first connecting rod mechanism. When the switch blade is closed, the first connecting rod mechanism drives the door locking mechanism to lock the cabinet door to prevent the cabinet door from being opened mistakenly when a solid-state insulating cabinet is working.

Description

technical field [0001] The invention relates to the field of electric power technology equipment, and more specifically relates to an operating system for a disconnector and a grounding switch in a solid insulation cabinet. Background technique [0002] At present, conventional solid insulated cabinets need to control the opening and closing states of the main switch and the grounding switch to avoid danger and damage caused by improper operation. When the cabinet door is closed, it is necessary to control whether the main switch and the grounding switch are allowed to operate, and to clarify the current state of the grounding switch. And when it is necessary to carry out maintenance operation to the switch cabinet, the cabinet door needs to be opened. At this time, for safety, the grounding switch must be grounded, and other personnel are prohibited from operating. [0003] When the solid insulation cabinet is in working state, if the cabinet door is opened at this time, d...

AI Technical Summary

Problems solved by technology

[0003] When the solid insulation cabinet is in working state, if the cabinet door is opened at this time, dangerous accidents are prone to occur. Therefore, an operating system that can prevent the cabinet door from being accidentally opened when the solid insulation cabinet is in the working state is needed. After the breaker is grounded, it can realize the opening of the cabinet door lock
