Structure characteristics of power capacitor

Modular structure

The intelligent power capacitor is of modular structure with small volume, simple field wiring and convenient maintenance. Only need to increase the number of modules can realize the expansion of reactive power compensation system.

High quality capacitor

The self-healing low-voltage compensation capacitor is adopted. The temperature sensor is built in the capacitor to reflect the internal heating degree of the capacitor and realize the over temperature protection.

Embedded switch module

Intelligent power capacitor has built-in switch module. The switching switch module is composed of thyristor, magnetic holding relay, zero crossing trigger conduction circuit and thyristor protection circuit, which realizes "zero switching" of capacitor and ensures no inrush current impact and no switching overvoltage during switching. The switch module has fast response and can be operated frequently.

Perfect protection design

The intelligent power capacitor has the functions of power failure protection, short circuit protection, voltage open phase protection, capacitor over temperature protection, etc., which can effectively guarantee the safety of the capacitor and extend the service life of the equipment.

Advanced control technology

The physical quantity is controlled as reactive power, and reactive power flow prediction and delay multi-point sampling technology are adopted to ensure no oscillation during switching. In case of heavy load, the reactive power is fully compensated.

Anti switching oscillation technology

The unique design principle is adopted to prevent non compensation or over compensation caused by controller crash, and to prevent capacitor switching oscillation.

Automatic reactive power compensation

Intelligent power capacitor automatically switches on and off according to the reactive power of load, dynamically compensates reactive power and improves power quality. The intelligent capacitor can be used by a single unit or multiple units on line.

Friendly man-machine interface

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

Display switching status, composite switch module fault status and communication status.

It is convenient to realize the functions of debugging / working state switching and manual / automatic operation.
