第 PAGE IV页 题 目ZPW-2000A型轨道电路的原理和技术条件 摘 要 ZPW-2000无绝缘轨道电路换装施工是全路第五次提速调图工程中最重要，最紧迫的信号工程，此次工程要求高、任务重、工期短，而且全路没有现成的开通测试项目集经验。通过对ZPW-2000无绝缘轨道电路的开通，维护测试，我们认为该轨道电路技术指标的测试调整是开通过程中最关键的无绝缘轨道电路的开通，维护测试，我们认为该轨道电路技术指标的测试调整是开通过程中最关键的一个环节，也是日常维护工作中的最重要的一个环节。 本论文主要阐述了ZPW-2000A无绝缘轨道电路是通过仿真技术开发的，是我国目前最先进的无绝缘、对信息移频轨道电路，其传输安全性、传输长度、可靠性、可维修性能较好，对器材的安装标准和系统指标要求十分严格。 本论文主要阐述了ZPW-2000A无绝缘移频自动闭塞系统的特点、构成、原理说明、区间通过信号机的设置、补偿电容的设置、闭塞区分电路等。 通过本次设计，初步掌握了ZPW-2000A的工作原理、故障处理步骤、方法、内容。 关键词 ZPW-2000A；无绝缘；轨道电路 Abstract ZPW-2000 jointless track circuit device construction is region fifth speed-increasing and rescheduling project the most important, the most urgent signal engineering, the engineering requirements, the task is heavy, short construction period, and the whole region without off-the-peg opening test project experience. Based on the ZPW-2000 jointless track circuit is opened, maintenance and test, we think that the track circuit testing adjustment is opened during the most critical of jointless track circuit opening, maintenance and test, we think that the track circuit testing adjustment is opened during the most crucial link, and daily maintenance in the work of one of the most important links. This paper mainly expounds the ZPW-2000A jointless track circuit is through the simulation technology development, is currently Chinas most advanced without insulation, on information frequency shift track circuit, the transmission security, the transmission length, reliability, good performance of equipment repair, installation standard and system of indicators are very strict. Through this design, the preliminary master ZPW-2000As working principle, fault processing steps, methods, content Key words ZPW-2000A; jointless track circuit; 目 录 TOC \o 1-3 \u 第1章 绪 论 PAGEREF _To\h 1 第2章ZPW-2000A无绝缘移频自动闭塞系统概述 3 2.1 ZPW-2000A 概述 3 2.2 ZPW-2000A型无绝缘移频自动闭塞系统特点 3 2.3 ZPW-2000A型无绝缘轨道电路系统构成 PAGEREF _To\h 4 2.3.1 室外部分 PAGEREF _Toc606
