22: Reactors are used vacuum dipping process, the high temperature bake curing. Coil has good
insulation properties, the overall mechanical strength, moisture resistance;
23: Coil is F, H class insulation system, greatly improving the reliability of long-term operation;
24: Low temperature, low loss, low cost, utilization rate;
25: The input reactor to limit the form of harmonic wave feedback circuit. They can also be reduced
because of the converted DC Link Capacitor input rectifier caused by AC current and frequency;
baseline reactor pressure drop UD = 2%, with a feeder unit for the drive and automatic operation
of the transformer, but also for uk <1% of the system operation.
Functions:
1. Reduction of harmonic wave,Improvement of the power factor.
2. Over-voltage restriction and clean the power grid.
3. Reducing the stress caused by noise to motorextended the life span of motor.
4. Improvement of low-frequency conduction emission/sensitivity.
