Description

Inverter and converter in use, often by the surge current and surge voltage from the impact, would seriously damage the inverter and the governor's performance and service life, so to install in front of the input reactance device, to suppress the surge voltage and surge current, protect the inverter and the governor, extending its life and prevent harmonic interference, and because the inverter and the governor's approach is the use of variable frequency speed control, so governor, he often will produce high-order harmonic distortion and the resulting waveform will affect the normal use of the device, this shall be the installation of a line input reactor to improve the inverter power factor and harmonic current suppression, filter harmonic voltage and harmonic current and improve power quality.

I. Features
1 power supply for other devices have significant interference (interference, over-voltage);
2 power supply voltage phase imbalance> 1.8% of rated voltage;
3 low impedance line (power transformer for the drive rating more than *0 times);
4 in a line to reduce line current and the installation of a large number of frequency;
5 Enter the reactor using cosφ (power factor) correction capacitors or power factor correction unit.
