摘要:
针对国内地铁运营时钢轨电位过高和钢轨电位限制装置频繁动作的问题，从直流牵引供电系统建模的角度出发，通过多种情况下钢轨电位的仿真计算，研究了单向导通装置和钢轨电位限制装置对正线钢轨电位的影响规律。仿真结果表明，单相导通装置的导通会使正线和车辆段的钢轨电位升高，钢轨电位限制装置的闭合会抬高其它较远处区间的钢轨电位。
Abstracts:
Aiming at the high rail potential and frequent actions of rail over-voltage protection device during the metro operation in China, from the perspective of DC traction power supply system modeling, the influence of track unilateral connecting device and rail over-voltage protection devices on rail potential of main lines is studied through the simulative calculation of rail potential under different conditions. The results show that the rail potential on main lines is higher when the track unilateral connecting devices are reversely conducted, and the actions of rail over-voltage protection device will increase the rail potential in other distant regions.
