The switchgear is a complete set of switchgear and control equipment. It acts as a power center and main distribution unit. Mainly used for control, monitoring, measurement and protection of power lines and main electrical equipment. It is often installed in substations, power distribution rooms, etc.
In addition to the functions, installation environment, internal structure, and controlled objects, the distribution box and the switchgear are characterized by different external dimensions. The distribution box is small in size and can be concealed in the wall and can stand on the ground. The cabinet is large, and only the equipment is in the substation and power distribution room.
The control box is used for power, lighting distribution and motor control inside and outside the building. It is suitable for indoor wall-mounted and outdoor floor-mounted power distribution equipment. Mainly used for fire pump control, submersible pump control, fire fan control, fan control, lighting distribution control, etc. The control mode has direct start control, star delta step-down start control, self-buck buck start control, inverter start control For various control methods such as soft start control, an isolating switch and a fuse switch can be used as the isolation breaking point.
The power distribution cabinet is equipped with switchgear, measuring instruments, protective appliances and auxiliary equipment in closed or semi-closed metal cabinets or screens according to electrical wiring requirements to form a low-voltage power distribution device. The circuit can be switched on or off with a manual or automatic switch during normal operation. There are many classifications of power distribution cabinets. In the event of malfunction or abnormal operation, the circuit or alarm is cut off by means of a protective device. The measuring instrument can display various parameters during operation, and can also adjust some electrical parameters to prompt or signal the deviation from the normal working state. Commonly used in various hair, distribution, and substation.
