Features of intelligent low-voltage system switchgear.

1) The composition of the switch cabinet

Intelligent switchgear overturns the traditional switchgear equipment equipment method, and the power inverter power system is composed of intelligent appearance, intelligent circuit breaker, intelligent motor protector, soft starter and programmable logic controller (PLC) and other intelligent equipment It replaces the traditional power inverter system composed of master equipment (common pointer appearance, circuit breakers, relays, contactors, fuses, thermal relays).

2) The operation and control method of the switch cabinet

The traditional switchgear is only suitable for on-site manual operation. The traditional power inverter system composed of all the main electrical components is often very complicated. It uses many elements and complex wiring. It is very inconvenient for daily operation and repair; while the smart switchgear is composed of Smart equipment and circuit breakers, relays, PLCs, etc. form a power inverter power system. There are few components in the system. The smart components are connected through a communication network. The wiring is simple. It can not only operate on site, but also long-distance monitoring. If installed General packet radio service (GPRS) equipment, using a mobile phone client, users can check the real-time working status of each element in the system anytime and anywhere.

3) Intelligent capacitance compensation of the system

Equipped with a smart capacitor compensation control cabinet using smart power inverter power system, smart capacitors and smart capacitor controllers form a complete capacitor compensation smart system, which can adjust the quality of power supply in real time and supply stable power to the power supply system.

4) Man-machine interface and communication management

The intelligent power inverter power system is equipped with a control cabinet alone, which controls the communication processing machine and the man-machine interface of the equipment in the control cabinet, and the man-machine interface is connected with the communication processing machine to display the working conditions of the equipment in the system in real time. The communication processing machine is connected to all the equipment on the entire power supply system, and it is connected to the gathering control room processing machine. The four remote functions of the power inverter power system can be realized through the communication processing machine.
