摘要
分析现行等阻抗钢轨引接线的设计缺陷;根据电磁学的涡流效应原理,提出了基于导线涡流效应的等阻抗引接线的设计;建立了基于导线涡流效应的等阻抗引接线等效电路和数学模型,分析了基于导线涡流效应的等阻抗引接线工作原理。实验结果表明基于导线涡流效应的等阻抗引接线在交流电气化区段能可靠的实现阻抗相等之目的,而且制造简单、维护方便。
The design defects of equal impedance track lead were analyzed. According to the principle of eddy current effect in Electromagnetism, a design of track lead with equal impedance based on wire eddy current effect was brought forward and a mathematic model of the equal electric circuit was built to ana- lyze the working principle of track lead with equal impedance. Experiment results indicated that track lead with equal impedance based on wire eddy current effect could realize equal impedance in an alternate electrified district and has the advantages of simplicity in manufacturing and convenience in maintenance.
