摘　　要：为提升HX_(D)1D型机车主断路器的运用可靠性,文章基于数字延时控制电路的结构与原理,在主断路器合闸前、合闸过程中和合闸后三种情况下,对电压上升沿时间过长或负脉冲干扰等特殊工况下的数字延时模块的控制边界开展试验研究,并针对主断路器无法合闸的情况提出了相应建议。In order to improve the reliability of the main circuit breaker of HXD1D locomotive, based on the configuration and principle of digital delay control circuit, this paper studies the control boundary of digital delay module under special conditions such as long time of voltage rising edge or negative pulse interference before,during and after the closing of the main circuit breaker, and corresponding suggestions are put forward for the situation that the main circuit breaker cannot be closed.
