Fault test method and detection system for alternating-current electric switch machine

Abstract

The invention discloses a fault test method and a fault detection system for an alternating-current electric switch machine, and the method mainly comprises the steps: collecting the sucking-up and falling-down states of a relay of each sub-combination TDF and a relay of a total combination TDD of the switch machine through an electromagnetic sensor; the core processor is utilized to check and determine the fault point of the switch machine point by point according to the contact position information of each relay and the sucking and falling states of each relay of the sub-combination TDF and the relay of the total combination TDD, and feeds back the judgment result to the display in real time, so that the method can replace manual judgment of the fault condition, and is higher in speed and more convenient to operate. The working efficiency is greatly improved, the fault judgment cost is reduced, and smooth railway transportation is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of fault detection of railway systems, and in particular relates to a fault testing method and detection system of an AC electric switch machine. Background technique [0002] A railway turnout is a line connection device that allows rolling stock to transfer from one track to another, and is usually laid in large numbers at stations. The turnout switch machine is a switching device for a turnout, which can be used to switch a turnout or lock a turnout. The failure of the turnout switch machine may lead to the derailment of the train on track, resulting in huge economic losses and casualties. [0003] With the development of railway technology, the technology of railway turnout conversion has appeared. The turnout control circuit is the key equipment to realize the switchover of the railway switch. Through the combination of the indoor switch control circuit and the outdoor switch machine, the switchover c...
