摘　　要：目前S700K转辙机在城市轨道交通领域应用广泛,但其机内的速动开关因单个故障率高极大影响了S700K转辙机的稳定性,也成为影响地铁运营的一个重要设备隐患。为此,提出对五线制S700K转辙机速动开关进行并联的优化方案,以提高设备的可用性和稳定性。Currently,Siemens S700 Kswitch machine has been widely used in the field of urban rail transit.Its stability has been affected seriously due to the high rate of single failure of its internal high-speed switch,which becomes a key hidden trouble of equipment for the operation of urban rail transit.To this end,we put forward an optimized scheme of the high-speed switch transformed in parallel of the five wire S700 Kswitch machine in order to improve the availability and stability of the equipment.
