复线接触网的感应电压危及施工人员生命安全 ,影响施工质量和进度。为了找到限制复线接触网感应电压的措施 ,对广州—深圳电气化铁道第三接触线 (以下简称第三线 )上的感应电压进行了实测 ,发现第三线悬浮状态时的感应电压可达 3 0 0 0V以上 ;第三线测试区段的一端或两端接地且相邻高速接触线 (以下简称高速线 )上无电力机车时第三线的感应电压基本可以忽略 ,当高速线上有电力机车时第三线感应电压瞬时超过数百伏。
The induced voltage of double line contact network endangers the life safety of construction workers and affects the construction quality and progress. In order to find out the measures to limit the induced voltage of the contact line of the double line, the induced voltage on the third contact line of Guangzhou-Shenzhen Electrified Railway (hereinafter referred to as the third line) was measured and found that the induced voltage of the third line in the suspended state can reach 3000V ; Third line test section of one or both ends of the grounded and adjacent high-speed contact line (hereinafter referred to as the high-speed line) on the third line when the induction voltage is almost negligible when high-speed line electric locomotive induction when the third line Voltage transient over hundreds of volts.
