摘要:
区间直流电缆短路故障将引起大范围正线停电，一旦发生必将影响列车运行。尽快解决区间直流电缆短路故障，缩短停电时间，对正常行车意义重大。分析了地铁直流电缆短路故障发生的原因，说明了故障点初判及处理的原则；详细介绍了抢修作业前的准备工作及抢修人员安排；阐述了故障应急处理程序，并重点描述了故障点确定及处理的相关事宜。该方案可有效节约故障处理时间，提高处理效率。
Abstracts:
Metro interval DC power cable fault will cause large-scale power failure on the main line and have serious impact on subway operation. It is significant for train safe operation to solve the short circuit fault and cut down the power failure time. In this paper, the causes of DC cable short circuit fault are analyzed, the principle of fault points preliminary detection and treatment is explained. Then, the preparations for rush repair and staffing, the emergency processing program are introduced in detail, the identification of the fault points and matters related to the emergency response are emphasized, so as to save the time for fault treatment and enhance the handling efficiency.
