Abstract

The invention relates to an interlocking device for a cable chamber door of a high-voltage switch cabinet. The interlocking device comprises a bracket, a transmission sheet, a pin shaft, an interlocking pull rod, an interlocking rod, an interlocking pull plate and the like. When the high-voltage cabinet cable chamber door is closed, force acts on the transmission sheet to drive the interlocking pull plate and drive the interlocking rod to be inserted into a top plate circular hole of the cable chamber door. When the grounding switch is operated to be opened, the cam on the grounding switch operation shaft tightly presses the interlocking rod and cannot rebound, so that the effect of locking the cable chamber door is achieved.

Description

technical field [0001] The invention relates to the technical field of high-voltage electrical equipment, in particular to an interlocking device for a cable chamber door of a high-voltage switch cabinet. Background technique [0002] "Five-proof interlock" is the necessary equipment for high-voltage switchgear. It is a protective measure to prevent operators from entering the contact with live intervals and prohibiting any misoperation of switches. It is the last barrier to protect operators and equipment. For high-voltage switchgear The importance of is self-evident. The existing interlocking device of the cable compartment door of the high-voltage switchgear is mainly realized by the direct insertion of the operating mechanism, which can only meet the requirements of the general high-voltage switchgear. The interlocking device of the cable room door in the prior art has a single structure, and the "five-proof interlocking" is not perfect, and there are many potential saf...
