30 hp dc reactor for sale, 22kW, 1 phase, dc reactor for inverter, the role of the reactor is to increase the power factor and reduce the instantaneous impact.
Features1. Improve the input current wave caused by capacitor harmonics.2. Reduce and prevent rectifier bridge damage and capacitors.3. Overheating due to a surge in current.4. Improve the power factor and reduce the AC pulse of the DC bus.5. Limit transient changes in system voltage.
Dimension (unit: mm)Tips: Smooth wave reactor function
The smooth wave reactor is an important component in the rectifier circuit. The main role in the intermediate frequency power supply is1. Limit the short-circuit current. (When the inverter thyristor is commutated at the same time, it is equivalent to a direct short-circuit of the rectifier bridge load.) Short-circuit without a reactor.2. Suppress the impact of intermediate frequency components on the power frequency grid.3. The filtering effect (the rectified current has an AC component; the high-frequency alternating current does not pass through a large inductor) makes the rectified output waveform continuous. If it is not continuous, there will be a time when the current is zero. At this time, the inverter bridge stops working, causing rectification. Open bridge phenomenon.4. The input power of the parallel inverter circuit has a reactive component throughput. The input circuit of the inverter bridge must have an element reactor for energy storage.
