摘要
高压单芯电缆在工程实践中,往往因为客观条件的限制,需采用金属护层单点接地方式。因此,需对电缆金属护层正常运行及接地短路时的护层感应电压进行分析计算,并针对云南特殊的环境要求,提出相应的处理意见和建议。
Because of the limits of the objective conditions, the high voltage single cable is always applied to the single point grounding mode. So, we need to promote the induced voltage analytical calculation of the metal jacket on power cables in cases of normal operation and grounded short circuit operation, and we promote the relevant opinions and suggestions aim at the special environmental requirements of Yunnan Province.
