关键词ZPW-2000A；无绝缘；轨道电路AbstractZPW-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 China's 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-2000A's working principle, fault processing steps, methods, contentKey words ZPW-2000A; jointless track circuit;目录第1章绪论 (1)第2章ZPW-2000A无绝缘移频自动闭塞系统概述 (3)2.1ZPW-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 (4)2.3.1 室外部分 ..................................... 错误!未定义书签。
