广州地铁三号线车厂线邻区3A6、3B6区在停电情况下,常有验电有电的现象,这是接触网残压所致。接触网残压直接威胁着人身安全,本文通过不同条件下测量数据和理论推断,分析接触网残压产生原因,结合现场情况研究出具体措施,大大削减接触网残压。
Subway Line 3A6,3B6 of Guangzhou Metro Line 3 depot in the case of power outages, often have the phenomenon of electricity and electricity, which is caused by the contact network residual pressure. Catenary residual pressure is directly threatening personal safety. Based on the measured data and theoretical inference under different conditions, this paper analyzes the causes of residual voltage on catenary and studies the specific measures to reduce the residual voltage of catenary.
