一直以来渡线道岔均被作为双动道岔进行控制,从电锁器联锁、电气集中,直到计算机联锁,渡线道岔双动被认为是天经地义的。渡线道岔为何必须双动,其根源就是从安全角度考虑。图1渡线道岔示意图图2复示分道岔示意图如图1所示,当办理A、D间进路时,1、3号道岔均必须转换到反位,此时1 All along, the turnout has been controlled as a double-action turnout, interlocking from the electric lock, electrical concentration, until the computer interlocking, turnout turnout is considered to be perfectly justified. Why turnout turnout must be double-action, its root is from a security point of view. Figure 1 schematic diagram of the turnout Figure 2 shows the turnout schematic diagram shown in Figure 1, when dealing with the way between the A, D, 1, 3 turnout must be converted to the anti-bit, this time 1
