摘　　要：在全路车站邻线干扰整治过程中,南昌局集团公司管内动车所高压脉冲轨道电路叠加ZPW-2000电码化区段在下调入口电流降低邻线干扰后,发生多次车载掉码现象。通过对掉码区段现场测试分析与邻线干扰仿真分析,针对动车所内区段长度较短的特点,采用去除区段内的补偿电容器后,提高电码化入口电流的方式,为解决动车所内高压脉冲电码化区段车载掉码和邻线干扰问题提供新的思路。When eliminating interference from adjacent lines for all the target stations,onboard code missing occurred many times after lowering entrance currents to reduce such interference in sections with high-voltage pulse track circuits and overlay ZPW-2000 coding in EMU depots under the control of China Railway Nanchang Group Co.,Ltd.In this paper,based on fi eld tests,an analysis of the codemissing sections and a simulation analysis of adjacent line interference,and taking into consideration the short lengths of the sections in EMU depots,a new idea is provided to solve the problems of onboard code missing and adjacent line interference in the high-voltage pulse coding sections in EMU depots.
