摘要
直流电缆作为直流输电系统中的主要载流部件,其运行状态关系着地铁牵引供电系统的稳定性。以广州地铁6号线高架段直流1 500 V高压电缆击穿故障为例,分别从电缆运行工况、故障原因探究、预防措施制定等方面展开论述,并简述电缆故障测试仪、超声波检测仪在地铁的应用,为同类型的地铁1 500 V直流电力电缆的安全运行提供参考。
The DC cable is the main carrier of the DC transmission system, and its running state is related to the stability of the metro traction power supply system. Taking the DC1500 V high voltage cable breakdown fault in Guangzhou metro line 6 elevated section as an example, the paper explores and discusses the aspects respectively of cable operation condition, causes of failures, preventive measures, and briefly introduces the use of the cable fault tester and the ultrasonic detector in metro, and provides reference for metro safe operation of same type of DC1500 V electric cable.
