摘要
分析了两起 10 k V单相电力电缆因金属屏蔽层中环流引起的故障。给出了几种常见敷设方式下单相电缆金属屏蔽层感应电压的幅值计算公式 ,计算结果与实测值较为吻合。提出了电缆安全运行的建议。
In this paper, two cable faults, due to circulating current in metal shield of electrical cables, are introduced. The calculation formulae for induced voltage in metal shield under different structure are given and calculation results are compared with measured results.
