1前言科吉富道岔是由法国引进的一种高速道岔(简称VPM法岔),它主要由尖轨锁闭检查器、芯轨锁闭检查器、密贴检查器组成。VPM用于高速道岔尖轨处,保证道岔尖轨的纵向伸缩。在道岔表示电路中,串联了VPM的接点,将道岔锁闭信息反馈给计算机联锁系统。具有锁闭检查、持续锁闭力强、工作稳定等特点。2小组概况合肥电务段高速道岔联合攻关小组概况,见表1。
1 Introduction KOJI FUDUTU is a kind of high-speed turnout introduced by France (VPM). It mainly consists of a rail-locked checker, a rail-locked checker and a close-in checker. The VPM is used at the sharp rail of the high-speed switch to ensure the longitudinal extension and contraction of the switch rail. In the switch circuit, the VPM contacts in series, the switch lock information feedback to the computer interlocking system. With lock check, continuous locking force, work stability and so on. 2 Group Overview Hefei electricity section of high-speed turnout research team summary, Table 1.
