Mechanical anti-misoperation locking device for 6kV high-voltage switch cabinet

Abstract

The invention discloses a mechanical anti-misoperation locking device for a 6kV high-voltage switch cabinet, relates to the technical field of high-voltage switch control, and aims to solve the problem that a worker cannot conveniently control a revolving door from the inner side of the revolving door while opening the revolving door since an existing anti-misoperation locking device is mainly controlled through a mechanical lock and is complex to operate. The mechanical anti-misoperation locking device for the 6kV high-voltage switch cabinet comprises a cabinet body, wherein a revolving dooris rotationally arranged on the front side of the cabinet body through hinge connection; a middle frame is fixedly arranged in the middle of the inner side of the revolving door; and a control shaft is rotationally arranged at a lower position in the middle of the inner side of the cabinet body. The revolving door can be fixed through a control rack; the revolving door can be controlled from the outside through a hand wheel; the revolving door can be controlled conveniently from the inside through a knob; and after the control shaft drives a main control gear to rotate, the control rack is meshed for moving towards one side, so that the revolving door can be aligned with the inner wall of the front side of the cabinet body by using the control rack, and can be fixed by matching insertion blocks.

Description

technical field [0001] The invention relates to the technical field of high-voltage switch control, in particular to a mechanical error-proof locking device for a 6kV high-voltage switch cabinet. Background technique [0002] High-voltage switchgear is to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in closed or semi-closed metal cabinets or on the screen width according to the requirements of electrical wiring. The safe control cabinet for personal and surrounding equipment generally consists of a surrounding shell and a revolving door to form a whole. [0003] After retrieval, for example, the patent No. CN208820251U discloses a 6kV high-voltage switchgear mechanical error-proof locking device, including a cabinet, the front of the cabinet is provided with a switch mechanism, and the back of the cabinet is provided with a cable compartment door panel. It is characterized in that: No. 1 mechanical lock is installed on the switch...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a 6kV high-voltage switchgear mechanical anti-mistake locking device, to solve the problem that the currently used anti-mistake locking device proposed in the above background technology is mainly controlled by a mechanical lock, which is cumbersome to operate. When opening the door, it is inconvenient to control the revolving door from the inner side of the revolving door, and cannot remind the passing staff to close the revolving door by mistake
