Performance characteristics and application fields of power capacitor

1. Modular structure

Intelligent power capacitor is modular structure, small volume, simple field wiring, convenient maintenance, and the expansion of reactive power compensation system can be realized only by increasing the number of modules

2. High quality capacitor

The temperature sensor 91 of self healing low voltage compensation capacitor is used to reflect the internal heating degree of the capacitor, and the over temperature protection is realized

3. embedded switch module

The switch module is composed of crystal barrier, magnetic holding relay, zero crossing trigger on circuit and crystal barrier protection circuit to realize zero switching of capacitor, so as to ensure that there is no inrush impact and no operating overvoltage during switching process. The switch module has fast response speed and can be operated frequently.

4. perfect protection design

Intelligent power capacitor has the functions of power failure protection, short circuit protection, voltage phase loss protection, capacitor over temperature protection, etc., which effectively guarantees the capacitor safety and extends the equipment life

5. Advanced control technology

The control physical quantity is reactive power. The multi-point sampling technology of pre Ba Qing delay is adopted to ensure the switching of the reactive power. When the load is heavy, the reactive power is fully compensated

6. anti switching oscillation technology

The unique design principle is adopted to prevent the non compensation or over compensation field caused by the controller failure and prevent the capacitor switching oscillation

7. Automatic compensation of reactive power

Intelligent power capacitor can automatically switch on and off according to the load reactive power, dynamically compensate the reactive power, improve the power quality. The intelligent capacitor can be used by one or multiple online

8. Friendly human-computer interface

Display current, voltage, reactive power and other equipment operation parameters.

Display switch status, composite switch module failure status, communication status

It can be used to switch the debugging working state and operate automatically manually.
