吉林局梅河口车辆段试制成功一套电动防护信号光电自动控制器,光电自动控制器是列检电动防护信号为了确保行车安全的配套装置。该光电自动控制器,是由磁感应轨道电路、光电发送装置、光电接收装置、GK-4光控器、控制继电器(A、B、C、D 4个)等部分组成。其工作原理是:安设在电动脱轨器所在地点的轨道两侧的光电发送装置和光电接收装置,平时不工作,当机车车辆通过磁感应轨道电路时,使磁感应轨道继电器工作,控制继电器A、B、C按次序开始工
Jilin Bureau Meihekou Vehicle Section trial success of a set of electric protection signal photoelectric automatic controller, photoelectric automatic controller is to check the electric protection signal in order to ensure driving safety of the matching device. The photoelectric automatic controller is composed of a magnetic induction track circuit, a photoelectric transmitting device, a photoelectric receiving device, a GK-4 light controller and a control relay (A, B, C and D). Its working principle is: installed in the location of the electric derailment on both sides of the optical transmission device and optical receiving device, usually do not work, when the locomotive through the magnetic track circuit, the magnetic induction track relay, control relays A, B C starts to work in order
