Copper wirewind input and output reactor to prevent harmonic interference

Brief introduction of three-phase input reactor:

1.The input reactor is a current limiting device, used on the input side of the drive, protect AC drive from transient over-voltage. There is lower surge and peak current, increase the true power factor, control the harmonic of the network and improve the action of the input current waveform.

2.There are two kinds of such reactors:Reactor reference voltage drop Ud= 2%, used for the frequency converter without feeding unit operation.Reactor reference voltage drop Ud= 4%, used for the frequency converter with feeding unit and automatic transformer operation, also used for the system of Uk less than 1% operation.

3.Testing standard:Rated operation voltage: 400VAnti-electric strength:  iron core winding 3000VAC/50HZ/5Ma, 10S no arcing breakdownInsulation resistor:  iron core winding 1000VDCΩ, insulation resistance ≥100mΩReactor noise:  less than 65dB( test with the reactor horizontal distance of 1meters)Product operation standard:  GB19212.1-2008  GB19212.21-2007  GB1094.6-2011

4. Application industry: inverter industry, crane, windlass, smelt, rolling equipment, port device, tower crane.
