Abstract

The invention discloses a mechanical error-proof locking device for a 6kV high-voltage switchgear, relates to the technical field of high-voltage switch control, and solves the problem that the currently used anti-mistake locking device is mainly controlled by a mechanical lock, and the operation is cumbersome. Sometimes, it is inconvenient to control the revolving door from the inner position of the revolving door. A 6kV high-voltage switch cabinet mechanical anti-mistake locking device, including a cabinet body; the front side of the cabinet body is twisted and connected with a revolving door; the inner side of the revolving door is fixed with an intermediate frame; the cabinet body There is a control shaft rotating at the lower part of the inner side of the inner side. By setting the control rack, the revolving door can be fixed. The revolving door can be controlled from the outside by using the hand wheel, and the revolving door can be controlled from the inside by using the knob. The control is convenient. Through the control The shaft drives the main control gear to rotate and then engages the control rack to move to one side. The control rack can be used to align the revolving door with the front inner wall of the cabinet and fix it with the insert block.

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...
