High voltage switchgear is the key equipment used to control, protect and distribute electrical energy in the power systems. Its accessories are important components to ensure the normal and safe operation of the distribution boxes, such as secondary socket interlocking mechanisms, bevel gear mechanisms, ZS displays, indoor electromagnetic locks, auxiliary switches, handles, door locks, door hinges, spare parts for loading vehicles, heating devices, ventilation devices, lighting devices, etc. The handles are used to open and close the switchgear doors. The door locks are used to prevent non-staff from opening the switchgear at will. The secondary socket interlocking mechanism ensures the correctness of the secondary plug-in and the device that limits the movement of the secondary line board. The bevel gear mechanism is a common gear transmission ventilation device. The indoor electromagnetic lock prevents the electric control mechanism interlocking device from electrical misoperation of high-voltage switchgear.
