摘要
结合军粮城牵引变电所等多所跳闸事件,从地铁或轻轨牵引直流供电系统设置的框架泄漏保护、DDL、双边联跳保护、排流柜等多种角度分析事件的起因,并提出了设计、运营维护改进和预防建议。
According to the accidents of in junliangcheng substations, the causes are analyzed from the following points of views of frame leakage protection, DDL, two way inter- tripping, current drainage cabinet and so on, which were equipped in DC traction power supply system of subway and light rail. The improvement and preventative suggestion about design and maintenance are also brought forward.
