Introduction:

The 10kV power purification device obtains 27.5kV input power from the secondary side of the traction transformer and provides a 10kV power supply meeting the requirements of railway power quality to the distribution substation after isolation, voltage reduction, voltage stabilization, and purification. The 10kV power supply can supply power to the substation, self-closing, and through the line.

Characteristics:

1. Dynamic voltage stabilization: Real-time compensation of input side voltage difference, elimination of voltage fluctuation on 10kV feeder, and solving the problem of three-phase voltage imbalance at the same time;

2. Active filtering: Automatically detect the harmonic content of input voltage, and inject reverse harmonics with the same magnitude into the output feeder through the coupling transformer to offset the voltage harmonics from the traction side;

3. Standby bypass: It has an automatic bypass power supply function to maintain the continuity of the system power supply.

Typical application:

        Power transformer + coupling transformer                                                   Step-down transformer

Bidirectional converter + HV cabinet
