Discussion on Troubleshooting of S700K Switch Control Circuit Faults

S700K electric switch machine is one of the commonly used switch equipment for railway transportation and plays an important role in increasing the efficiency of railway transportation. In everyday use, faults in the five wires of an S700K switch often cause failure in switch transition or loss of switch indication. Because of the complexity of the circuits, it is more troublesome to fix the errors. In this paper, on the basis of field experience, the types of failures caused by five-wire faults are listed and analyzed one by one, with a view to shortening the delay time and restoring the order of transportation as soon as possible.
