摘要
依托津秦客运专线信号电缆的现场实测条件,结合既有电气化铁路通信线路受电磁影响的经典理论分析,详细论证并布置了信号电缆单、双端接地对比测试方案,获得了近百趟列车的丰富可靠数据,实现了在不同接地方式下,高速铁路现场实测信号电缆芯线受电磁影响的详细测试和分析。
Based on the field test conditions of Jin-Qin high-speed railway signal cable and combined with classical theoretic analysis of electromagnetic influences on communication lines in electrified railway, the author expounded the scheme of comparative test for single and double grounding of signal cables in detail. Reliable and abundant data has been collected through nearly a hundred of field tests. Detailed testing and analysis of electromagnetic effects on signal cable core wire could be conducted in different modes of grounding
