摘要
介绍了西安地铁直流牵引供电系统中轨道回流的特性,并对运营线路中发生的较为典型的道岔转辙机产生电火花现象进行了分析;结合直流牵引供电系统的特点,为消除道岔转辙机发生电火花现象的处理措施提出了建议。
In this paper,the characteristics of track return current in traction DC power supply system of Xi'an metro are introduced,the typical electric spark phenomenon on metro line turnout switch machine is analyzed.Combines with the characteristics of DC traction power supply system,corresponding treatment suggestions are put forward to eliminate the electric spark phenomenon of the turnout machine.
