Input and output reactors for variable frequency speed regulation: During the use of frequency converters and speed governors, they are often impacted by surge currents and voltages, which can seriously damage their performance and service life. Therefore, input reactors should be installed in front of them to suppress surge voltages and currents, protect frequency converters and speed governors, extend their service life, and prevent harmonic interference, At the same time, due to the frequency conversion method used by the frequency converter and governor for speed regulation, high order harmonics and waveform distortion are often generated during speed regulation, which can affect the normal use of the equipment. Therefore, an output reactor must be installed at the output end to filter out harmonic voltage and current, improve the quality of the power grid. Our factory produces input and output series reactors, Made of high-quality imported silicon steel sheets and high-quality copper wire through advanced technology, it has the characteristics of small volume, low temperature rise, and no noise. The reactors supporting the frequency converter include: input AC reactors, output AC reactors, DC reactors, etc. Our company's reactors are fully matched with imported and domestic frequency converters from Siemens, ABB, Hitachi, Toshiba, and other brands.
