地下交越导体的阻性耦合

Resistive Coupling of Crossing Buried Conductors

为研究交流电气化铁路与地下导体任意交越时阻性耦合的影响，以Ｅ．Ｄ．Ｓｕｎｄｅ地中导体传输特性理论为基础，通过忽略地下导体的反作用，推出阻性耦合影响下，与交流电气化铁道任意交越的地下导体上的感应电流公式，并以垂直情况为例验证了Ｅ．Ｄ．Ｓｕｎｄｅ的结果。

To study the effect of resistive coupling between alternative electrified railway and near buried conduct crossing with any angle. Based on E . D. Sunde ' s theory on transmission of buried conduct and the omission of buried conduct reaction , approximate formula of current on buried conduct due to resistive coupling between alternative electrified railway and underground conduct crossing with any angle is given. When alternative electrified railway and underground conduct crossed with right angle , the formula is simplified to the result given by E. D. Sunde.
