Series reactors are connected in series to power capacitors. They suppress harmonics in the power grid and prevent problems caused by unusual events such as transient overcurrent and overvoltage that are generated by opening and closing of power capacitors. The series reactors are fire-resistant because the coils are molded using epoxy resin.
After the reactor is connected in series with the capacitor, it can effectively suppress the harmonic amplification, improve the voltage waveform of the system, increase the power factor of the system, and effectively suppress the closing inrush current and operating overvoltage, effectively protecting the capacitor. Model and meaning
age and power factor reduction. Therefore, series reactors need to be installed at the front end of capacitors to suppress and absorb harmonics, protect capacitors, and avoid the influence of harmonic voltage and impulse voltage and current, Improve power quality, improve system power factor an
Reactor capacity = matching capacitor capacity x reactance rate. For example, if 50kvar capacitor is connected in series with 7% reactor, then reactor capacity = 50kvar x 7% = 3.5kvar. Reactance ratio refers to the ratio of reactance value of series reactor to capacitance reactance value of capacitor bank.
The common reactors used in the power system areseries reactors and parallel reactors. The series reactor is mainly used to limit the short-circuit current, and it is also used in series or parallel with the capacitor in the filter to limit the higher harmonics in the power grid.
One of the unwanted effects is the overheating of capacitor banks that are needed to maintain the power factor within the parameters required by the power authority, with a resulting, significant reduction in the average working life. The ideal solution is to insert block reactors in series with capacitor banks.
