摘要:
机车通过电分相时，在不同位置其运行状态互换过程中有可能会产生电磁震荡和过电压。过电压可能会导致车顶损坏、接触网的绝缘被击穿等，从而影响机车的安全运行。文章针对这些问题，研究机车过牵引网电分相的电路参数，利用PSCAD/EMTDC仿真软件建立"机车-牵引网-电分相"的联合仿真模型，并模拟过分相的过程。得出机车在过分相过程中出现电弧放电的地方产生可能过电压，可为抑制过电压提供理论依据。
Abstract:
When a locomotive passes through the electric phase division, it may generate electromagnetic shock and over voltage in the process of changing its operation state in different positions. The over-voltage may cause damage of the roof and breakdown of the catenary insulation, etc., which will affect the safe operation of the locomotive. In view of these problems, this paper studies the circuit parameters of locomotive going through electrical sectioning of the traction network. PSCAD/EMTDC simulation software was used to establish the joint simulation model of "locomotive-traction network-electric separation",which simulates the process of locomotive going through electrical sectioning. It is concluded that the locomotive may produce over-voltage where arcing occurs in the process of locomotive going through electrical sectioning of the traction network,which provide a theoretical basis to suppress the over-voltage.
