ABNORMALITY MONITORING DEVICE OF TROLLEY WIRE, ABNORMALITY DETECTION METHOD AND ABNORMALITY ANALYSIS PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an abnormality monitoring device of a trolley wire or the like which can detect a variety of kinds of abnormalities related to the trolley wire or a pantograph by an arc which is generated at a contact point between the trolley wire and the pantograph of an electric railway, an abnormality detection method and an abnormality analysis program.;SOLUTION: An abnormality monitoring device of a trolley wire comprises: a plurality of wire-separation measurement instruments 11 to 13 which are arranged at intervals in a vehicle traveling direction of the trolley wire 4, and detect arcs which are generated at contact points between the trolley wire 4 and a pantograph; and a calculation device 14 which determines an abnormality of the trolley wire between detection zones by comparing a generation pattern of the arcs which are detected by the wire-separation measurement instruments 11 to 13 with a reference generation pattern of the arc.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
