浅谈大同站改造特殊过渡施工

A Brief Discussion on the Special Transition Construction of Datong Station Transformation

针对大型枢纽车站大同站站场改造,信号专业同步实施微机联锁改造工程。其中既有站设备为6502电气集中,室外直流电动转辙机,改造后室外为三相交流液压转辙机。通过和几个成熟信号施工过渡方案比对,设计出最合理方案,即采用交流液压转辙机过渡代替其他方案,以实现较大枢纽车站短时间高难度改造,达到信号施工过渡安全、优质、高效、经济的目的。

In view of the station reconstruction of Datong station, which is a large hub station, the signal specialty synchronously implements the microcomputer interlocking reconstruction project. The existing station equipment are 6502 electric centralization and outdoor DC electric switch machine, and after transformation the outdoor hydraulic switch machine is three phase AC. Through comparing with several mature signal construction transition schemes, the most reasonable scheme is designed, that is, alternating current hydraulic switch machine is used to replace other schemes,so as to realize the short time and high difficulty transformation of the larger hub station, the purpose of safety, high quality, high efficiency and economy of signal construction transition can be achieved.
