The switchgear is used to control various devices on and off. The main components are circuit breaker contactors or starters or electronic control boards, control buttons or handles and accessories. Applications are broad. All walks of life. The switchgear is an electric device. The external line first enters the main control switch in the cabinet, then enters the sub-control switch, and each shunt is set according to its needs. Such as instrumentation, automatic control, motor magnetic switch, various AC contactors, etc., some also have high-voltage room and low-voltage room switchgear, with high-voltage busbars, such as power plants, and some also have low-cycle to protect the main equipment. Reduced load. So what are the models of the switchgear ? What are the uses? Next, the decoration of the home decoration network will be explained for you.

What are the components of the switchgear?
1. Switch cabinet - vacuum circuit breaker
"Vacuum circuit breaker" is named for its high dielectric energy due to its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing; it has the advantages of small size, light weight, suitable for frequent operation, and no need for overhaul of arc extinguishing. The application in the power grid is more popular. The vacuum circuit breaker is an indoor power distribution device in a 3～10kV, 50Hz three-phase AC system, which can be used for protection and control of electrical equipment in industrial and mining enterprises, power plants and substations, especially suitable for oil-free and less For maintenance and frequent operation, the circuit breaker can be configured in the central cabinet, double cabinet, and fixed cabinet for controlling and protecting high voltage electrical equipment.
2. Switch cabinet - microcomputer protection device
Microcomputer protection is composed of high integration, bus chipless single chip microcomputer, high precision current and voltage transformer, high insulation strength outlet intermediate relay, high reliability switching power supply module and other components. The microcomputer protection device is mainly used as a power plant, substation, substation, etc. with a voltage level of 110KV and below. It can also be used as a protection and measurement of the voltage and current of the system in the voltage level between 70V and 220V.
The above is what the small series introduces to you about the switchgear model, what are the components of the switchgear, if you want to know more about the switchgear, please continue to pay attention to our home decoration network.
