High Voltage Reactive Power Compensation Equipment

Brief introduction
Rongxin high voltage reactive power compensation equipment is widely used in distribution wires with voltage between 10kV and 35kV. The reactive power compensation device is enabled to keep combination control of line voltage and reactive power through auto-switching of capacitor. Therefore, it is able to increase power factor of lines effectively, reduce line loss and improve voltage quality of power supply lines.

Independently developed high speed vacuum switch is adopted for capacitor switching. Our reactive power compensation equipment has its high speed switch and control power transformer placed in a stainless steel case, and automatic control box in a small control case. And then, they are installed together with a high voltage parallel capacitor and drop-out fuse, etc on a single pole to form a compact structure, which ensures convenient installation and debugging.
We can set our high voltage reactive power compensation equipment according to diversified technical demands of customers. The reactive power compensation equipment is able to conduct automatic switching of high voltage parallel capacitor banks by means of automatic judging and analyzing through seven control modes, i.e. time, voltage, time-voltage, reactive power, voltage reactive power, current and power factor.

At the same time, our reactive power compensation device has fault forecasting property before switching, thus avoiding blind switching and optimizing compensation to the greatest extent. In this way, life time of switches can be largely lengthened.
Furthermore, our reactive power compensation equipment has complete defensive functions, including capacitor delay protection, overcurrent protection, over voltage protection, low voltage protection and fault protection, etc. Additionally, the high voltage reactive power compensation equipment has wire and wireless communications functions.

Functions
1. The reactive power compensation device has auto and manual operation modes.
2. Zero-voltage-switch can be achieved, and overvoltage and inrush current are largely lowered.
3. Based on the particular case of reactive power compensation, users can select varied control methods, including time, voltage, time-voltage, reactive power, voltage reactive power, current and power factor.
4. Our high voltage reactive power compensation device conducts real time measurement and calculations of capacitor voltage, current, active power, reactive power and harmonic waves, etc.
5. The complete defensive functions of the reactive power compensation equipment include protection for overvoltage, low voltage, overcurrent, short circuit, lack of phase, etc, which ensure safe operation of equipment.
6. It sends various operating parameters and operational status to the host computer or the remote control centre through fieldbus or wireless network, and meanwhile receives information and orders from the host computer. In this way, the high voltage reactive power compensation equipment keeps supervisory control of field equipment.
7. Human-computer interaction is achieved through coordination of keyboard and liquid crystal display. As you can input set parameters and function set-up by keyboard into controllers, which work on fixed information and display the settings and operating results by liquid crystal display.

Technical features
Time dispersion of independently developed high speed vacuum switch is within 1ms.
Zero-voltage-switching drastically reduces overvoltage and inrush current.
The predictive function saves the high voltage reactive power compensation equipment from blind switching and greatly lengthens the lifetime of switches.
