摘　　要：高速铁路无砟轨道区段安装通过信号机在国内尚无先例,针对高速铁路无砟轨道、AT供电条件下的信号机安全距离不能满足相关规范要求的问题,分别从信号机安全距离、信号机显示等方面进行分析研究,提出采用降低信号机高度满足信号机距离带电体安全距离的解决方案。Because there was no precedent in China about installing the passing signals at ballastless track of high-speed railway, the purpose of this study was to solve the problem： the distance of signals under AT power supply mode at ballastless track of high-speed railway could not meet the safety distance requirement of relevant standard code. Meanwhile this paper made an analysis and study from relevant aspects, including signal safety distance, signal display distance and so on. Eventually, this paper put forward the solution in which the height of the signals should be lowered so as to meet the requirement of safety distance between the signal and the charged body.
