Reasearch On Detector For Catenary Suspension State In Heavy Haul Railway

Catenary,which is erected along the railway line,is an important power supply equipment for electrified railways,the catenary equipment is prone to abnormal state because of its complex and changeable geographic environment,line conditions and weather conditions.With the continuous development of electrified railways,the requirements for safety of railway transportation are higher and higher,while,the safety of heavy haul railways is of great significance to the national economy.On the premise of the continuous development of power supply 6C technology,the author takes Daqin Railway as the research object,and on the basis of the existing catenary suspension state detector,through the actual testing,improves the device to meet the actual operation needs.Firstly,the research describes the background of catenary suspension detector and the technical conditions that the equipment should meet.Then,the structure of detector with basic function is introduced.Through on-line detection,the problems existing in the process and results are analyzed and solved one by one,and the detector is continuously improved,so that it has stable and comprehensive detection function.After that,the effect of the application of the device is analyzed,and the value of the device is elaborated,so as to solve the problems of difficult and inefficient inspection of catenary equipment under normal operation conditions of Heavy-haul Railway and realize high-speed inspection of catenary.
