本文分析了东风_8型机车在电阻制动工况下发生活接地是由于ZC接触器断电时励磁绕组产生的高电势造成的,提出了增设ZC接触器延时断开的措施。
This paper analyzes the live grounding of the DF_8 locomotive under the condition of resistance braking due to the high potential generated by the excitation winding when the ZC contactor is de-energized, and puts forward the measures to delay the opening of the ZC contactor.
