摘要
随着电网建设与改造不断深入,近年来交联电缆已广泛应用在架空线路改入地、新建变电站配网出线中,电缆的故障也随之增多,其中电缆受潮引起绝缘降低是导致电缆故障的重要因素。通过对交联电缆从制造到运行维护全过程可能受潮的原因分析,提出了防止交联电缆受潮的措施。
With the development of power grid construction and renovation gradually in recent years, the cross linked cable has been utilized extensively in different aspects, such as changing overhead lines into underground lines and being used as outlet line of newly - built substation etc. Therefore, the cable faults increase accordingly. Experiences indicate the main factor which causes the cable faults is insulation degradation caused by cable wetting. The wetting reasons that may exist in the process of manufacture, operation and maintenance are analyzed and the preventive measures are proposed in order to prevent wetting.
