一、前言采用臂板电锁器联锁的车站,在我国铁路信号设备中占很大比重。尤其是在半自动闭塞区段,更是被广泛采用。过去设计时,臂板电锁器的结线方式,均参照部批8001电线器联锁結线通用图进行设计。我们利用该通用图,已先后在我局锦承、叶赤等线共设计了单双导线臂板电锁器联锁,有出站和无出站信号的11个车站。经过两年以来现场实际使用,大家反映部8001电锁器联锁结线通用图结线复杂,手柄接点使用过多,现场维修困难,维修工人不易掌握。尤其在电路中还设有架空外线混线设备,在使用中容易起副作用,使臂板信号开放后发生自动复起现象。根据以上这些缺点,经我处信号设计人员的共同研究,大胆提出了一种适用于平行道岔多,且具有交流电源车站的新结线方案——即在结线中采用锁闭继电器的方案(参阅图2)。此种结线方式,
I. INTRODUCTION The station that uses the interlocking arm lock system accounts for a large proportion of the railway signaling equipment in our country. Especially in the semi-automatic block section, it is widely used. In the past design, arm padlock connection method, are part of the batch reference 8001 wire interlock interlock design. We use the common map, has been in our office Jin Cheng, Ye Chi line design a total of single and double wire arm interlock, with outbound and outbound signals 11 stations. After two years since the actual use of the scene, we reflect the Ministry of 8001 interlock lock wiring common wiring complex, excessive use of the handle contacts, on-site maintenance difficulties, maintenance workers not easy to grasp. Especially in the circuit also has overhead outside the line of mixed equipment, easy to play in the use of side effects, the arm plate signal automatically after the phenomenon of opening up. Based on these shortcomings, the joint study of the signal designers I boldly proposed a new junction scheme for parallel stations with AC power stations - that is, the use of a latching relay in the junction See Figure 2). Such a connection method,
