减小动车所机车测试环线电磁干扰的研究

Research on Reducing Electromagnetic Interference on Locomotive Test Loop in EMU Depot

根据银川动车所内机车测试环线的故障情况,建立系统模型,分析测试环线在实际使用过程中所受的电磁干扰;提出"8"字交叉环线、加装空扼流变压器以及在一侧钢轨接缝处加装绝缘的解决方案,减小了电磁干扰影响,解决了机车ATP上码不稳定的问题。

According to the fault situation of locomotive test loop in Yinchuan EMU depot,the system model is established to analyze the electromagnetic interference on the test loop in actual operation. The solution of opposed blade type cross loop, installing air choke transformer and installing insulator at the joint of one side rail is put forward, which reduces the influence of electromagnetic interference and solves the problem of unstable locomotive ATP’s code.
