摘要
电力机车在通过过分相区时,主要有三种方式,其中车载自动过分相是目前应用较多的一种方式。对机车辅助系统和列供系统的供电方式进行了简要分析,其主要的供电方式有牵引变流器中压供电和主变压器绕组供电两种。对几种典型机车过分相过程中辅助系统和列供系统的供电情况进行了试验分析,得出在机车通过过分相区时,列供系统和辅助系统都不断电是目前比较理想的方式。提出通过优化升级实现对现有机车的辅助系统和列供系统的升级改造具有重要意义。
There are mainly three ways for electric locomotives to pass neutral section,whereby on-board auto-passing of neutral section is the mostly used scheme. Power supply modes of the locomotive auxiliary system and the train power supply system were briefly analyzed.Traction converter middle-voltage power supply and main transformer windings power supply were two main approaches. Power supply situation of the auxiliary system and train power supply system in the process of typical locomotive passing neutral sections were tested and analyzed,and it was concluded that the ideal way was to maintain uninterrupted power supply for both systems. It is of great significance to propose that the existing locomotive auxiliary system and train power supply system be optimized and upgraded.
