摘要
对110 kV单回路高压单芯电缆线路正常工作情况下金属护套产生的感应电压进行计算,并结合110 kV XLPE电力电缆工程设计中的典型实例,采取金属护套交叉互联接地方式,将电缆线路全长分成3等分段或3的倍数分段,限制高压单芯电缆护套感应电压,确保电缆的安全运行,减少运行损耗,效果良好。
This article analyzes the induction voltage in metal sheath of 110kV single-loop high-voltage single-core cable under normal operating conditions, and introduces a typical example in the engineering design of 110kV XLPE power cables.The measure of metal sheath cross-connected grounding can limit the induction voltage in metal sheath of high-voltage single-core cable,so as to ensure the safe operation of the cable,reduce operating loss and achieve good effects.
