摘要
介绍了"和谐"系列电力机车传动系统和接地检测装置,包括HXD1、HXD2、HXD3这3种车型。比较分析了3种车型接地故障检测方法并说明了各自的优缺点。通过仿真进行比较,结果表明HXD1和HXD3接地检测系统符合正常运用的要求,HXD2机车接地时可能出现两点接地,其接地检测有必要改进。
The drive system and grounding detection equipment of HXD serial locomotives were introduced, which included HXol, HXD2 and HXD3. Grounding detection method of three locomotives were compared, and the advantage and disadvantage of each were studied. Comparison was performed by simulation and the results showed that the grounding detection of HXDI and HXD3 meet with the require- ments of operation and that of HXD2 should be modified because of possible two-point grounding.
