Abstract

PURPOSE: To provide an apparatus enabling to detect the vehicle that has caused trouble from one end of a train, by impressing oscillation voltage on the adjacent line extended in parallel with grounding trouble detecting cable, and measuring the voltage induced in the trouble detecting cable.
CONSTITUTION: In case that grounding trouble is caused with jumper socket 30 of control circuit 41 for controlling air-blast circuit breaker of vehicle 1', connecting cord 7 is extended from pressurizing output terminal 7' of detector 6 to terminal 3 of adjacent line 42. At the same time, output terminal 8' for grounding vehicle body is connected to grounding terminal 5 while input terminal 9' is connected to trouble detecting cable 41. Trouble detecting oscillation voltage is impressed from terminal 7' onto adjacent line 42, and voltage induced at input terminal 9 is measured. Since induction voltage corresponding to the distance from the position of terminal 4 to position 30 where trouble is caused is developed at the terminal 9, the position 30 can be detected from the measured voltage. With such an arrangement, it is enabled to detect vehicle that has caused trouble, with no need of detaching the train circuit.
