Research On The Improvement Of Catenary Maintenance Mode

Railway traction power supply system is a subsystem of the whole railway system.The catenary system is a vulnerable to the influence of multiple system which power to the electric locomotive without any standby.Catenary of safe and reliable operation is the key to the safe and reliable operation of the electrified railway.It’s a very important driving device which play an important role in aspects of energy consumption In the protection of railway transportation safety, improve the transportation efficiency, reduce transportation.Since China railway electrification developed in our country,catenary mode, has experienced the failure of maintenance, the cycle and state trim phase. Maintenance mode appeared a lot of change. The operation of the high-speed railway catenary maintenance with the "prevention first, heavy repair" for the guidelines, according to the principle of "cycle detection, state maintenance".It take the way of combined cycle and state trim group assignments.The operation main body is still in the workshop and shift of the minimum operating unit.This operation mode security risk point, low working efficiency, to take up more manpower resource requirement for high, personal quality and operation effect, already cannot satisfy the requirement of railway rapid development.In this paper, on the basis of theoretical analysis, by way of research, through the period of catenary operation of realism, inquiry, investigation means to master the current power supply workshop practices, working procedure, regulation, personnel management, overall analysis of the existing catenary maintenance mode. And according to the related theory to decompose, analysis, and put forward the corresponding improvement Suggestions, combining the situation of China’s current rapid development of high speed railway, take advantage of both state repairing, following in the service of the railway transportation as the ultimate goal, on the basis of exploring to remove existing maintenance mode cost manpower, financial resources, inefficient ills such as a new mode of maintenance.Using the high speed railway power supply security detection monitoring system, innovation of catenary operation organization structure, a new model of planning can improve the catenary inspection efficiency, to ensure that the whole power supply system in does not affect the premise of the train operation, guarantee a safe and reasonable maintenance and maintenance. In this paper, the catenary current maintenance mode has carried on the detailed research and discussion, compared the previous done some of the maintenance model, at the same time, the system analysis of the current catenary maintenance exist some disadvantages, and finally, in improving the catenary maintenance mode, improve the ability of railway transportation, improve the catenary safety reliability are proposed.
