Product description
The series of dry iron core inlet and outlet reactors are used in series with the input and output ends of the frequency converter to serve as the incoming line reactor and the outgoing line reactor of the frequency converter. When the inverter is working, it will generate large harmonics, mainly in 5, 7, 11 and 13 times. The harmonic content is very high. If the line reactor is not installed, the service life of the inverter and other equipment will be greatly shortened. When the harmonic interference is severe, some equipments will not operate normally. After adding the line reactor, the harmonic content will be greatly reduced, the power factor of the power grid will be improved, and the safe operation of the inverter crying and other loads will be ensured to ensure other The equipment is not affected by harmonic interference; the addition of the line reactor can passivate the steepness of the inverter output voltage (switching frequency) and reduce the disturbance and impact of the power components in the inverter. Moreover, the reactor can effectively suppress the inrush current of the circuit at the moment of load closing, and protect the inverter device and other components in the circuit from overcurrent impact.

Features
1. The power supply has obvious interference to other equipment (interference, overvoltage)
2. Power phase-to-phase voltage imbalance > 1.8% of rated voltage
3, the impedance of the line is very low (power transformer is more than 10 times the rated value of the inverter
4. A large number of inverters installed on one line to reduce the line current
5. Use COS? (power factor) correction capacitor or power factor correction unit
