近几年以来,我国的铁路信号技术发展迅速,电子元器件已经被普遍运用到现代信号技术设备之中。现代信号系统之中最主要也最常用的两种系统是计算机联锁系统和区间无绝缘移频自动闭塞系统。本文主要结合实际,详细分析了铁路信号系统的结构和电力牵引供电系统的结构,具体研究了牵引供电系统产生干扰信号的原因以及干扰信号如何进入铁路信号系统的渠道,积极地寻求措施,从而加强信号系统设备抗干扰性能方面的施工方法。
In recent years, China’s rapid development of railway signaling technology, electronic components have been widely used in modern signal technology equipment. Two of the most important and most commonly used systems in modern signaling systems are computer interlocking systems and range-free automatic frequency-shift blocking systems. In this paper, the structure of the railway signal system and the structure of the electric traction power supply system are analyzed in detail in this paper. The causes of the interference signal generated by the traction power supply system and how the interference signal enters the channel of the railway signal system are studied in detail. Signal system equipment anti-jamming performance aspects of construction methods.
