The invention discloses an overhead line electric locomotive anti-electric shock device based on a PLC architecture, the device is installed in an electric locomotive rectifier cabinet, the rectifier cabinet is internally divided into three parts, and the three parts are respectively a main circuit switch part, a transformation rectification part and a control part. The interior of the rectifier cabinet is divided into three connection areas according to the arrangement of components, and the first connection area is connected with a switching power supply, a PLC, an air switch, a control transformer, an intermediate relay KA1 and other components from left to right. The second connection area is connected with an isolation switch, an over-current relay, a fast-melting fuse and other components from left to right. The third connecting area is composed of a rectifier tube, a main transformer and other components which are electrically connected through connecting wires.
