在列车密度和速度不断提高、站内调车作业日益增多的情况下,采用人工扳道的电锁器联锁车站,已难以适应运输的要求。正逐步以电气集中联锁取代之,并同时进行站场改造,增加车站到发线和咽喉区道岔组数。在站场分步改造过程中,对于新铺设且又要在施工过渡期间投入运用的道岔,先安装转换锁闭器交付使用,然后在电气集中换装开通时,再更换成电动转辙机。按照传统的施工方法,安装装置将一起更换。由于电锁器联锁车站的咽喉区无信号机和轨道电路,车站由电锁器联锁改为电气集中联锁的换装开通要点期间,主要工
With the increasing density and speed of trains and the increasing number of shunting operations inside the station, it is difficult to adapt to the requirements of transportation by using interlocking stations with manual switchboards. Electricity is gradually being gradually replaced by an interlocking system, and at the same time, the station will be rebuilt to increase the number of turnout lines in the stations and the throat area. During the step-by-step transformation of the station yard, switch traps installed newly and put into operation during the construction transition should be installed and put into use first, and then be replaced with electrical switch machines when the electrical switchover is started. According to the traditional construction method, the installation device will be replaced together. Because the electric lock interlocking station no signal and track circuits in the throat area, the station by the electric lock interlock to electric focus on the interlocking dressup opening period, the main work
