地絡位置標定方法及び地絡位置標定システム
Document Type and Number:
Japanese Patent JP6962879
Kind Code:
B2
Abstract:
To provide a ground-fault position locating method capable of easily locating a ground-fault position when a ground fault occurs while reducing an installation cost of a ground-fault position locating device.SOLUTION: Each of a plurality of propulsion coils 7 includes a conductor 71 and a semiconductive layer 74. A conductor part 16 is formed of a plurality of conductors 71 serially connected with each other, and a semiconductive layer part 17 is formed of a plurality of semiconductive layers 74 connected to each other. When a ground fault occurs, a voltage is guided to the plurality of propulsion coils 7 by causing a vehicle 2 to run in a feeding section PS in a state that an inverter 11 and the plurality of propulsion coils 7 are disconnected, and a ground fault position is located on the basis of a measurement value of a voltage V1 between the conductor part 16 and the semiconductive layer part 17 measured when the voltage is guided.SELECTED DRAWING: Figure 8
