1、Product use
Capacitor in the reactive power compensation circuit are often subject to harmonic current, inrush current and overvoltage impact, resulting in the capacitor is easy to damage. Therefore, series reactor with a certain proportion, to suppress and absorb part of harmonic, can significantly improve the reliability and stability of the power supply system, in many cases, such as harmonic content, you must matching capacitors and reactors in series.
The main function of series reactors is:
1 suppress the harmonic amplification, and filter out a certain proportion of the harmonic.
2 with the accurate collocation, the passive filter can be formed with the capacitor series and can filter out the harmonic of a certain time.
3 to inhibit the flow of the input capacitor, protect capacitor and other components.
★Special tips:
1 the loop of series reactors can still play a reactive power compensation, but the capacity of the compensation is less than the series reactor, and the capacity of the series reactor is reduced..
2 series reactor will increase the voltage on the capacitor. The capacity of the series reactors is determined by the increase of the number of the reactors.. This must be taken into account when selecting a capacitor model.
