| 摘 要： | 目前带回流线的直接供电方式在电气化铁道中被广泛采用。本文应用电磁耦合原理对带回流线的直接供电方式牵引网进行了分析计算,就回流线截面对牵引网电流分配、弱电线路的屏蔽效果和牵引网阻抗等各方面的影响进行了计算,结合回流线价格对回流线截面的选择进行了技术经济比较,为实际工程中回流线截面的合理选择提供了依据。

| Abstract: | The mode of TRNF is widely used in the electric railway recently. In this paper the calculation of the traction power system of TRNF was made applying electric-magnetical coupling method, the relations of the current distribution, screening effect of the traction power system to the communication line and the impedance of the overhead contact line via cross section of the return current wire are discussed. Then the reasonable selection method of the return current wire by technical and economical comparation is given. |
