计算机联锁和ZPW-2000A四显示自动闭塞设备作为铁路信号自动控制主体设备,在技术上产生了跨越式的进步,在电源方面也与以往的车站和区间信号设备有本质的不同。本文针对计算机联锁和ZPW-2000A四显示自动闭塞设备电源混线故障进行了分析,并区分电源线间混线和电源与地线混线两种情况,提出了相应的故障处理方案,有效消除了计算机联锁与ZPW-2000A设备电源混线的安全隐患。
Computer interlocking and ZPW-2000A four display automatic blocking device as the main control device of railway signal has made a leap-forward progress in technology and is also different in power from past station and interval signal devices. In this paper, computer interlocking and ZPW-2000A four display automatic blocking device power supply line fault analysis, and to distinguish between the power line mixed power and ground and power line two kinds of situations, put forward the corresponding fault handling program, effectively eliminate Computer interlocking and ZPW-2000A equipment power supply line of the security risks.
