track return circuit

基本解释

An impedance bond is an interface transformer providing a path for a return propulsion current on electrified railway and a signal current of a track circuit.
扼流变压器是电气化牵引回流和轨道信号电流之间的接口器件。
Considering the earth return of the high-speed railway track circuit, a fast and simplified formula for calculating the mutual impedance is studied in this paper.
考虑大地影响，推导了相邻轨道电路互阻抗简化表达式。
In electric railway track circuit, the two steel tracks are both transmission line of the track signal and return line for electric locomotive tractive current back to electric substation.
在电气化铁路轨道电路中，两条钢轨即是轨道信号的传输线，又是电力机车牵引电流返回变电所的回流线。
