The invention provides a rear door grounded interlocking device for a high voltage switch cabinet, which is applied to the technical field of high voltage switch gears. According to the rear door grounded interlocking device, a rear door (1) is movably connected with a cabinet body of the switch cabinet; the interlocking device comprises an interlocking part (3) and a lock bolt piece (4); an open slot (5) is formed on the interlocking part (3) passing through the rear door (1); the interlocking part (3) is mounted on the rear door (1); the lock bolt piece (4) is arranged on the cabinet body of the switch cabinet; a flexible assembly (6) is arranged on the lock bolt piece (4); and when the rear door (1) is closed to the cabinet body of the switch cabinet, the flexible assembly (6) is set as a structure capable of being clamped in the open slot (5). The rear door interlocking device provided by the invention has a simple structure; the grounded interlocking device can be guaranteed to be conveniently and rapidly unlocked; the rear door grounded interlocking device has an emergency unlocking function so as to avoid the problems of damage to the switch cabinet and the like, which are caused when equipment in the switch cabinet has a fault, and the cost of the switch cabinet is saved.
Description
technical field [0001] The invention belongs to the technical field of high-voltage switchgear, and more specifically relates to a grounding interlocking device for the back door of a high-voltage switchgear. Background technique [0002] In the current power system, the grounding interlocking device of the back door of the high-voltage switchgear is mainly composed of interlocking parts and locking parts. Since the grounding interlock is welded, when the internal parts of the switch cabinet fail and the rear door needs to be opened urgently, the grounding interlock device cannot be opened conveniently and quickly, so it does not have an emergency unlocking function, which brings trouble to the maintenance of the switch cabinet and seriously Otherwise, it will cause serious damage to the switchgear and other losses. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-voltage high-voltage lock with a simple st...
