摘　　要：简述了武汉铁路局HXD1B型机车BVAC.N99D型主断路器(简称HVB)反馈信号丢失故障概况,分析了HVB反馈信号丢失的故障机理,通过改进反馈信号线路设计,增加中间继电器及连接线路形成一条HVB分断反馈信号旁路,替代原有HVB断开反馈信号传输路径,提升了信号传输的迅捷性,保障了HVB运用的稳定性、可靠性。The general situation of feedback signal loss of BVAC.N99 Dhigh voltage breaker(HVB for short)of HXD1B locomotive of China Railway Wuhan Bureau Group Co.,Ltd.is briefly described.The failure mechanism of HVB feedback signal loss is analyzed.By improving the design of feedback signal circuit,added intermediate relays and connecting lines to form a bypass of HVB breaking feedback signal to raplace the original transmission path of HVB disconnection feedback signal,the rapidity of signal transmission is improved,and the stability and reliability of HVB operation are ensured.
