摘要
针对目前和谐型机车在冬季雾霾天气运用过程中,出现车顶高压设备"雾闪"并造成绝缘降低的现象,从雾箍天气对高压电气设备绝缘的影响、防"雾闪"技术改进等方面进行了分析论述,提出了改进思路。
Aiming at the phenomenon of HV device fog flash and lower insulation during HX locomotive operated in haze weather of winter, this paper makes the technical analysis for haze weather affecting insulation of HV electric device, analyzes the technical modification of anti--fog flash, and also puts forward the design improvement.
