ABSTRACT: If the pantograph of an urban rail transit train stays at the insulating anchor joint for a long time, it will cause a prolonged discharge between the pantographs, which may burn or even break the contact wire and interrupt the power supply. In order to prevent similar faults from happening in the future and provide references for other urban rail transit operation and construction units, this paper analyzes the principle and hazards of the fault caused by the train stopping in the power supply not-allowed zones from the perspective of principle, as well as the extent of the fault’s impact. Meanwhile, it proposes relevant measures and methods to prevent the train from stopping in the power supply not-allowed zones from two aspects: the design of not-allowed zones signs and driving restrictions in the not-allowed zones.
