zpw-2000A轨道电路故障案例分析研究 摘 要 中国高速铁路时代的来临，使人民的生活也越来越方便，交通设备的安全性也成为了人们关注的重点。因为人为控制安全隐患较多，就需要通过自动化控制来提高设备安全性。在我国铁路的起步阶段，信号传输系统极为简单以及落后，依靠人工瞭望，人工驾驶等等，其安全系数非常之低。列车运行也应时代需要，对自动化控制的要求也逐步提升。但在实际运行过程中，设备需要解决的问题也变得复杂和繁多，这就需要我们熟悉了解设备的性能和技术特点来快速、准确的处理故障。因此笔者通过对在我国铁路建设之中使用较多的自动闭塞系统所使用到的ZPW-2000A型轨道电路加以分析，概括其结构情况、如何进行运作以及各组成部分所产生的效用，另外对该电路比较多见的问题也加以阐述。并希望通过本文的描述可以对提高电务维修人员的业务水平及经验的累积。 文章通过下面四个部分对本文所研究的轨道电路加以分析研究。第一部分，对文章涉及到的研究的背景以及目的加以说明；第二部分，对本文所研究的轨道电路加以简要说明，包含其构成部分以及如何进行运作；第三部分，详细分析了对本文所研究的轨道电路所具备的电气特点；第四部分，对于本文所研究的轨道电路比较多见的问题加以分析，同时提出解决问题的办法。 关键词 自动化控制；ZPW-2000A；故障处理 西南交通大学网络教育毕业设计（论文） 第 PAGE 3页 Abstract With the advent of Chinas high-speed railway era, peoples life has become more and more convenient, and the safety of transportation equipment has become the focus of peoples attention. Because there are many hidden dangers in human control, it is necessary to improve the safety of equipment through automatic control. In the early stage, Chinas railway signal technology was very backward. Train operation should also meet the needs of The Times, and the requirements for automatic control are gradually improved. But in the actual operation process, the problems to be solved by the equipment also become complex and various, which requires us to be familiar with the performance and technical characteristics of the equipment to quickly and accurately deal with the fault. This paper mainly introduces the composition, working principle and functions of zpw-2000a track circuit in automatic block system of railway equipment, and analyzes some common equipment faults. It is hoped that the description in this paper can improve the professional level and accumulation of experience of electrical maintenance personnel. This paper describes the zpw-2000a track circuit mainly from the following three aspects. 1. Brief introduction of zpw-2000a track circuit, including its system composition and working principle; 2. The electrical characteristics, test metho
