The application of intelligent capacitor

Date of release:2019-07-05 Author: Click:

Intelligent capacitor integrates modern measurement and control, power electronics, network communication, automation control, power capacitor and other advanced technologies. The backward controller technology of traditional reactive power compensation device and the backward mechanical contactor or electromechanical integrated switch are used as switching technology of switching capacitor, and the large and heavy structure mode of traditional reactive power compensation device is changed, so that the new generation of low voltage reactive compensation equipment has better compensation effect, smaller volume, lower power consumption, lower price and cost saving More, more flexible, more convenient maintenance, longer service life, higher reliability, adapt to the higher requirements of Modern Grid Reactive compensation.


The composition of intelligent capacitor

Intelligent capacitor is designed as a modular module, which consists of high-quality capacitor, intelligent measurement and control module, switch module, line protection module and human-machine interface module.


Basic functions of intelligent capacitor

Intelligent capacitor can be used by one or multiple on-line. Instead of the conventional automatic reactive power compensation device composed of intelligent controller, fuse, composite switch or mechanical contactor, thermal relay, low voltage power capacitor, indicator lamp and other wires.


Performance characteristics of intelligent capacitor

Intelligent capacitor is modular structure, small volume, simple field wiring and convenient maintenance. Only increasing 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, and 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

The intelligent capacitor has a switch module built in. The switch module consists of thyristor, magnetic holding relay, zero crossing trigger on circuit and thyristor protection circuit to realize "zero switching" of capacitor, so as to ensure that there is no inrush current impact and no operating overvoltage during switching. The switch module has fast response speed and can be operated frequently.


Perfect protection design

Intelligent 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.


Advanced control technology

The control physical quantity is reactive power, and the reactive power flow prediction and delay multi-point sampling technology are adopted to ensure the switching of the oscillation. When heavy load is applied, the reactive power is fully compensated.


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.


Automatic compensation of reactive power

Intelligent capacitor automatically switches according to the magnitude of load reactive power, dynamically compensates reactive power and improves power quality. Intelligent capacitor can be used by one or multiple on-line.


Friendly human-computer interface

Display the operating parameters of current, voltage, reactive power and other equipment.

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

It can also realize the functions of debugging / working state switching and manual / automatic operation.


Application field of intelligent capacitor: intelligent reactive power compensation capacitor provides solutions for improving power supply factor and power grid efficiency.


The main application fields are: residential area distribution system, municipal commercial building, traffic tunnel distribution system, box transformer, complete cabinet, outdoor distribution box.
