Power background:

1), high voltage 35KV side traction rectifier inverter device generated by the high harmonics, the dominant harmonic is 11 times, 13 times, 23 times 25 times;

2), low side of the natural power factor is low, the work of the night load reactive power and harmonic fluctuations;

3), high pressure side of the natural power factor is higher, due to the long supply line, at night when the load is low when the phenomenon of power backwards;

Recommended solution:

1), the harmonic using APF active filter through the step-up transformer directly connected to the 35KV below the bus, filter high harmonics.

2), reactive power compensation using HDVG through 10KV step-up transformer connected to the bus below 35KV, two-way adjustment of power factor to prevent reactive power back.

Customer benefits:

Reduce the harmonic content, and ensure the safe and stable operation of the power supply system of the metallurgical industry;

Power factor safety upgrade, to avoid the fines caused by reactive power;

Energy saving, reduce harmonic content, to avoid equipment malfunction.

reduce manufacturing cost
