摘要
针对一些煤矿使用中性点直接接地的三相电源向井下供电的问题,提出了用零序电抗器对三相电源的中性点接地进行隔离和对线路分布电容进行补偿的方法。
In view of the problems existed in the use of three-phase power supply with neutral-point directly earthed for supplying power to the underground in some coalmines, a method using zero-sequence reactor to isolate the neutral-point earthing of three-phase power supply and compensate the line distributed capacitance is put forward.
