Characteristics of output reactors
2023-04-14
Output reactor, also known as motor reactor, is used to limit the capacitive charging current of the motor connection cable and to limit the voltage rise on the motor winding to within 54OV/us, generally the power of 4-90KW inverter and motor cable length exceeds 50m, the output reactor should be set, it is also used to passivate the inverter output voltage (steepness of the switch) and reduce the components in the inverter (such as IGBT). e.g. IGBTs) and to reduce disturbances and shocks to the components in the inverter. Output reactors are mainly used in industrial automation system engineering, especially where inverters are used, to extend the effective transmission distance of the inverter and to effectively suppress the instantaneous high voltage generated when the IGBT module of the inverter is switched on and off.
Instructions for the use of output reactors: In order to increase the distance between the inverter and the motor you can thicken the cable appropriately, increase the insulation strength of the cable and try to use non-shielded cables.
Characteristics of the output reactor:
1, suitable for reactive power compensation and harmonic control;
2, the main function of the output reactor is to compensate the effect of the distributed capacitance of the long line and to suppress the output harmonic current;
3、Effectively protect the inverter and improve the power factor, can stop the interference from the grid and reduce the pollution of the grid by the harmonic currents generated by the rectifier unit.
