摘要： PROBLEM TO BE SOLVED: To provide a device and a method for preventing wear of a trolley cable capable of reliably preventing wear of the trolley cable by the necessary minimum operation, and minimizing damages even when an accident such as ground fault occurs.
SOLUTION: The device comprises first and second current measuring instruments 4A, 4B which are fitted to overhead trolley contact wires 2A, 2B located at both ends of an air section 3 for changing the first overhead trolley contact wire 2A and the second overhead trolley contact wire 2B to measure the currents Ia, Ib running in the air section 3; a making switch 6 which is connected to the overhead trolley contact wires 2A, 2B to change the open state and the short-circuit state between the overhead trolley contact wires 2A, 2B; and a control unit 7 which inputs the measurement values of the currents Ia, Ib and the potential difference V, and changes the making switch 6 in the short-circuit state when satisfying the wear caring conditions D1-D9 in which the wear of trolley cables 2At, 2Bt is cared in the air section 3.
