Title:
CORROSION DIAGNOSTIC METHOD AND CORROSION DIAGNOSTIC DEVICE
Document Type and Number:
Japanese Patent JP2019082369
Kind Code:
A
Abstract:
To provide a corrosion diagnostic method and corrosion diagnostic device for increasing the accuracy of the corrosion diagnosis of an electric wire.SOLUTION: An exciting coil 11 and a detection coil 12 are disposed on an electric wire so that the central axis is along the radial direction of the electric wire 2. The exciting coil 11 and detection coil 12 are moved along a circumferential direction Y1 and a longitudinal direction Y2 of the electric wire 2. Thus, the exciting coil 11 and detection coil 12 are disposed at a plurality of different points on the electric wire 2. A control unit 17 integrates the outputs of the detection coil 12 detected at the plurality of different points, and diagnoses the corrosion state of the electric wire 2 on the basis of the integration value.SELECTED DRAWING: Figure 6
