Catenary Suspension State Inspection Research Of High Speed Railway Overhead Contact System

Rapid development of high speed railway in China, long routing link up one after another is bound to bring new operation organization pattern change.In order to meet the need of transportation, equipment management unit must adopt advanced technology and equipment, to improve the efficiency of maintenance, guarantee the stability of the equipment.At present, the high-speed railway catenary suspension state detection research mainly focused on the technical level, there arn’t comprehensive and systemic research about application for field devices and combination with production organization.This article in view of the existing catenary inspection standard, technology principle, combining with all kinds of devices in catenary suspension state detection aspects of practical application, analysis and evaluate detecting technology. Emphasis on 1c and 4c, from the system structure, technical principle, to the actual application situation, the existence question, and the improved method, integrating theory with practice, discuss the optimization of inspection organization pattern.At the same time comparative study on detection of the rules of the new and old catenary maintenance rule, combine with the current equipment technical conditions, the production organization pattern, exploring the optimization under new maintenance rules, the catenary suspension state in order to improve the detection mode, and put forward effective suggestions for field application.
