The power supply method when the feeder fault occurs in the power supply arm

Abstract

The invention provides a power supply method of feeder fault of power supply arm, which comprises: receiving the feeder fault information; identifying faulty feeder according to the feeder fault information; if the feeder is positive feeder, switching the power supply method of the power supply arm from AT power supply mode to the direct and backflow power supply mode. The power supply method of feeder fault of power supply arm solve the problem that electric locomotives on the railroad are impassable when experts check and repair the fault of feeder after feeder fault, which reduces the impact on railway traffic in feeder fault and utilizes that the power supply arm can keep supplying power to railway in feeder fault so that the operation of the electric locomotive won't be affected.

Description

technical field [0001] The invention relates to the field of railways, in particular to a power supply method when a feeder fault occurs to a power supply arm. Background technique [0002] The connection line of the Dazhun-Shuohuang Railway--Zhunchi Railway is powered by AT power supply. Since it was put into operation in 2015, statistical analysis of the failures of the power supply arm found that the feeder has a high probability of failure. The number of work areas set up is small, for example, 3 work areas are set up for 172 kilometers, and each work area governs about 60 kilometers of lines. When the feeder fails, the staff needs to spend a lot of time to find the fault. , The electric locomotives on the railway are impassable, and the investigation and repair takes a long time, so the failure of the feeder has a great impact on railway transportation. Contents of the invention [0003] Based on the above problems, the present invention proposes a power supply metho...

AI Technical Summary

Problems solved by technology

[0003] Based on the above problems, the present invention proposes a power supply method when a feeder failure occurs in the power supply arm, which solves the problem that the electric locomotive on the railway cannot pass when the feeder fails, and when the fault of the feeder is checked and repaired, the problem is reduced. The impact of feeder failure on railway transportation has been eliminated, and the power supply arm can continue to supply power to the railway when the feeder fails, so as not to affect the operation of electric locomotives
