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.
