During the use of the switchgear, check it regularly to ensure safety

Switchgear (also known as complete set of switch or complete set of power distribution device) is an electrical equipment based on circuit breakers; it means that the manufacturer connects related high and low voltage electrical appliances (including control electrical appliances, protective electrical appliances) according to the requirements of electrical primary wiring diagrams. , Measuring appliances), as well as bus bars, current-carrying conductors, insulators, etc. are assembled in a closed or open metal cabinet as a device for receiving and distributing electrical energy in the power system.

The switch cabinet is an indispensable member of the electrical industry. The switch cabinet door lock is also an important part of the switch cabinet. The safety of the switch cabinet is closely related to the safety of the door lock. Therefore, during the use of the switchgear, the relevant supporting equipment should be checked in time to ensure safety!
