高压单芯电缆外护套烧蚀故障分析

Analysis on Ablation Fault of Outer Sheath of High Voltage Single Core Cable

高压单芯电缆在供电中发挥着非常重要的作用。研究表明,高压电缆会因其护套外产生悬浮电压或环流等因素,引起电缆外套的烧损,从而引发安全事故,影响供电网络的安全运行。所以,非常有必要研究高压电缆护套烧蚀机理及应该采取的相应保护措施。

High voltage single core cable plays a very important role in power supply.The research shows that the high voltage cable will cause the cable jacket burning because of the factors such as suspension voltage or circulating current,which will lead to safety accidents and affect the safe operation of power supply network.Therefore,it is very necessary to study the ablation mechanism of high voltage cable sheath and the corresponding protective measures.
