微机保护是通过微型计算机构成的各种电力保护的一种手段和方法,是通过高可靠性、高灵敏度和高选择性来对铁道线路进行检测和保护的一种方法。电气化铁道已经得到大面积的推广应用,对保障铁路运输的安全畅通发挥了巨大作用。现总结了电气化在铁道运输过程的相关保护措施和一些常见的故障类型,通过对工作经验的总结提出了在研制新一代微机保护时应注意的技术问题。 Microcomputer protection is a means and method of various power protection formed by a microcomputer and is a method of detecting and protecting a railway line with high reliability, high sensitivity and high selectivity. The electrified railway has been widely popularized and applied, which has played a great role in ensuring the safe and smooth development of railway transportation. Now summed up the electrification of the railway in the transport of the relevant protective measures and some common fault types, through the summary of work experience proposed in the development of a new generation of computer protection should pay attention to the technical issues.
