摘　　要：高速铁路电力贯通线采用单芯电缆敷设在轨道两侧的电缆槽内,由于受电气化铁路和自身通过的交变电流的影响,电缆金属护套产生的感应电压已经严重影响了运营维护人员的人身安全和电力设施的安全运行。本文重点研究了高速铁路电力贯通线单芯电缆的金属护套感应电压的各种影响因素,通过理论分析并结合CDEGS仿真计算软件,建立不同运行电流下的牵引供电系统及电力贯通线仿真计算模型,对单芯电缆护层保护器接地方式、电力贯通线电缆自身通过的电流、电缆的长度以及不同运行电流下的牵引供电系统等因素进行了仿真分析。The high-speed railway power transmission lines adopt single conductor cable to be laid in the cable tank on both sides of the track.Due to the effects of electrified railway and the alternating current passed through itself,the inductive voltage produced by metal sheath of cable has seriously affected the personal safety of operation and maintenance personnel and the safe operation of power facilities.This paper focuses on the study of various factors affecting the metal sheath induced voltage of single conductor cable in the high-speed railway power transmission line.Through theoretical analysis and CDEGS simulation calculation software,the traction power supply system and power transmission line simulation calculation model under different operating currents are established,which includes factors such as the grounding methods of single conductor cable sheath protector,current through the power transmission line itself,the length of the cable and the traction power supply system with different operating currents are simulated and analyzed.
