DC reactor DCL is mainly used in industrial/factory automation control system, installed in the inverter, speed regulator and power grid, input reactor between, used to suppress the surge voltage and current generated by the frequency converter, governor, etc. , and to attenuate the system to a greater extent, in the use of high-order harmonics and distortion harmonics in the frequency converter and governor, it is often impacted by surge current and surge voltage, which can seriously damage the performance and service life of frequency converter and speed reducer, it is used to restrain surge voltage and surge current, to protect frequency converter and governor, to extend their service life and to prevent harmonic interference, therefore, high-order harmonics and waveform distortion are often produced during speed regulation, which will affect the normal use of equipment. Therefore, it is necessary to install an incoming line reactor at the input end to improve the power factor of the frequency converter, number and suppress harmonic current, filter harmonic voltage and harmonic current, improve power quality converter DC reactor DCL-120 application conditions.

1, power supply has obvious interference to other equipment (interference, overvoltage) power supply phase voltage imbalance 1.8% of the rated voltage

2, extremely low impedance line (power transformer is more than 10 times the rated value of the converter)

3, in a line to reduce line current installed a large number of converters

4, use COSP (power factor) correction capacitance or power factor correction unit
