| 摘 要： | 当高速公路平行接近共用走廊的多回超高压输电线路时，高速公路机电系统的通信光缆和低压电缆需面对输电线路短路故障时产生的强大磁感应和地电位升的考验。为保障高速公路机电系统的安全运行，提出综合防护方案，包括输电线路上架设良导体架空地线，机电系统的通信光缆采用无金属光缆，低压电缆尽量远离输电铁塔以及采用高耐压电缆并加装过电压保...

| Abstract: | When expressway is adjacent to the corridor in which multi-circuit extra high voltage AC(EHVAC) transmission lines are arranged,the communication optical fiber and low voltage cables in electromechanical system of the expressway have to be faced with strong magnetic induction and earth potential rise while short-circuit fault occurred in the transmission lines.To ensure the secure operation of electromechanical system of the expressway,a synthetical protection scheme is proposed,which includes erecting over... |
