Abstract

This paper concerns the effect of configuration of high voltage power cables on induced voltages in their metallic sheaths. One, two or three cables per phase and phase sequence of the cables are considered. Computing of the voltages was performed for a normal operation and in case of earth fault. Various ways of the sheaths bonding are considered as well. Shock hazard and voltage stress of non-metallic outer sheath of cables are evaluated. Favourable configurations of the power cable system are indicated.

高压电力电缆系统中感应护套电压的计算机辅助分析
本文研究了高压电力电缆结构对金属护套内感应电压的影响。考虑每相一根、两根或三根电缆以及电缆的相序。计算了正常运行和接地故障情况下的电压。同时还考虑了护套的各种粘结方式。对电缆非金属外护套的冲击危险性和电压应力进行了评价。指出了电力电缆系统的有利配置。
