摘要
基于积分方法对接触网与控制电缆之间的电磁耦合进行分析,推导出控制电缆上感应电压的计算公式。在AT供电方式下,分别仿真了机车受电弓与接触网接触和分离两种不同情况下,控制电缆末端的感应电压。从仿真结果可以看出,当机车与接触网接触和分离时,控制电缆上的感应电压发生突变,而且谐波很多,感应电压很大。因此接触网对控制电缆的电磁干扰能够引起接触网开关的误动。
Based on the integral method analyzes the electromagnetic coupling between the control cable and the catenaries, a calculation formula of control cable' s inductive voltage has been deduced. Under the conditions of the AT power supply and simulation of the locomotive by the pantograph and the catenary contact and separate two different circumstance are presenfed. The end' s inductive voltage of control cable was simulated. From the simula- tion' s conclusion, the control cable' s induced voltage mutated and many harmonics and the induction voltage is very large, when the contact and separation of the locomotive with the catenary. Catenary cable control electromag- netic interference cause malfunction of the catenary switches
