Variable frequency speed control with and output reactor: in the using process of frequency converter and speed governor, they will often suffer from the surge current and surge voltage impact, and may lead to serious damage to their performance and service life, so the reactor is needed to install in front of them to suppress the surge voltage and surge current, protect the frequency converter and speed governor, extend its service life and prevent the harmonic interference. At the same time, since the control of frequency converter and the governor is realized by frequency conversion, so it often produces high-order harmonics and waveform distortion which will affect the normal use of equipment. Therefore, an output reactor must be installed in the output for filtering out harmonic voltage and harmonic current and improving the quality of the grid. The and output series of reactor produced by our company use high-quality imported silicon steel sheet and copper wires by the advanced technology from refining and have the advantages of small volume, low temperature rise, no noise and so on. The following are the related technology indexes.
