Low Voltage Reactive Power Compensation Devices


Low Voltage Reactive Power Compensation Devices picture Email:inter@snta.com.cn

Function of device
1. Stabilize the voltage and enhance the voltage qualification rate;
2. Dynamic reactive compensation enhances the power factor;
3. Absorb the harmonic current, reduce the equipment temperature and prolong the service life;
4. Enhance the power factor, reduce the line loss and save the electric energy;
5. Release the transformer capacity, enhance the transformer utilization ratio and increase the active output of transformer.

Features of device

1.Through the thyristor, the automatic contactless switching of each filter bank is achieved; the filter employing the advanced thyristor flexible switching technology and special process design avoids the rush current and transient impulse generated by the conventional contactor switching and thyristor zero-cross switching, allowing the subsequent operation without discharging. This will prolong the service life of dynamic compensation system.
2. It can not only automatically trace the system reactive load variation, carry out quick reactive compensation, but also smooth the harmonic current in the power system to maintain the power factor within the specified range. Besides, the capacitor and reactor in series can avoid the harmonic magnification.
3. The filter bank switching controlled by the controller enhances the quick-response capacity of filter bank and allows the dynamic and frequent switching according to the load condition of power distribution system. The dynamic response time does not exceed 20ms.
4.The powerful functions and easy adjustment LCD controller enables the real display of system voltage, power factor, input system filter bank number and compensation current etc. It can program the power factor, overvoltage value, no-voltage value, overcurrent value, percent harmonic distortion value, switching time-lag and allows the warning functions for overvoltage, overcurrent, undercurrent and equipment temperature of 60℃ etc.
5. It can realize the three-phase switching or switching per phase according to the three-phase equilibrium load and out-of-balance load.
6. This equipment is specially designed according to the custom system to enable the evident smoothing effect and meet the national standard. The power factor after compensation is not less than 0.93.
SNTA1003 low voltage dynamic reactive compensation smoothing equipment adopts the thyristor switching electric power filter to supply a new solution to the dynamic compensation of increasing the power factor, smoothing the harmonics, stabilizing the voltage, improving the quality of electric power, saving energy and reducing the loss.
