采用自动控制原理,对自动接地装置的隔离开关状态、电网接地状态等信息进行检测,利用PLC逻辑编程控制、IC卡、机械连锁等技术,实现对电力机车整备作业场的安全挂接(撤)地线的远程操作及安全联控。执行电路采用继电器联锁控制的电器设计,自动挂接地线装置设计成电机驱动的摇杆机构,机械臂采用双四杆机构,保证电力机车整备作业场接挂地线的自动化。
Using automatic control principle, the automatic grounding device isolation switch status, power grid ground state and other information to be detected, the use of PLC logic programming control, IC card, mechanical interlocking technology to achieve the safety of electric locomotive maintenance work (withdrawal) Ground the remote operation and safety control. The implementation of the circuit using relay interlock control of electrical design, automatic connection grounding device designed as a motor-driven rocker mechanism, the robot arm with dual four-bar mechanism to ensure that the electric locomotive preparation site to connect to the ground automation.
