track return circuit

基本解釋

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.
扼流變壓器是電氣化牽引回流和軌道信號(hào)電流之間的接口器件。
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.
考慮大地影響，推導(dǎo)了相鄰軌道電路互阻抗簡(jiǎn)化表達(dá)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.
在電氣化鐵路軌道電路中，兩條鋼軌即是軌道信號(hào)的傳輸線，又是電力機(jī)車牽引電流返回變電所的回流線。
