摘要
针对天铁110kV变电站频繁发生短路故障问题,实践中摸索出根据主变10kV侧电流的变化,计算短路故障电流,准确推断故障点位置的方法,迅速排除故障恢复正常供电。
In view of the trouble that short circuit occurred frequently in 110kV transfer substation,the method that uses change of 10kV side current of the main transfer substation to calculate the current of short circuit and infer accurate trouble point position and remove the trouble rapidly has been found out in practice to recover power supply.
