南山煤矿新井谐波治理方案探讨

Nan Shan Coal Mine New Well Overtone Government Plan Ciscussion

鹤矿集团南山煤矿供电系统中,含有大量谐波源。其中主要谐波源负载为新井3 m25绞车和副井绞车。由于可控硅整流产生大量谐波,整流变和硅整流间的电缆发烫,曾有测量仪器乱码等现象,消除谐波危害,现就新井谐波源负载分别进行谐波治理。

In the crane ore group Mr. Nan coal mine power supply system, includes the massive overtone source. And the main overtone source load is the new well 3 meters 25 winches and the auxiliary shaft winch. Because the silicon- controlled rectifier rectification produces the massive overtones, the rectification changes with the silicon rectification the electric cable feels hot, once had phenomena and so on metering equipment additive device, the harmonic cancellation harm, presently separately carries on the overtone government on the new well overtone source load.
