摘要
通过对一起单芯电力电缆线路敷设不规范造成线路保护跳闸事故的原因分析,提出单芯电力电缆的不同排列方式对电缆阻抗、电缆屏蔽层感应电压和电缆线路零序电流的影响,并制定了整改措施。
Through the analysis on the cause to result in the power transmission line protection trip operation by a single core cable with its laying quality below the standard, this paper expatiates the different effect of the different array mode of the power cable to the cable impedance, shielding layer induced vohag and zero-order current and the improvement measure are also given.
