Catenary Insulator Filth On-line Monitoring Technology Research

With the accelerating speed of railway electrification,especially the rapid development of high-speed railway.The locomotive of railway realize the electric traction basically,but no standby power for electric locomotive.Once the electric power interrupt event by catenary,it will lead to the whole train without power supply that will trigger mass incidents easily.And now the development direction of railway is high speed and overloading.The demand of Pantograph catenary relationship is higher and higher,The power supply reliability requirements is higher and higher.And catenary insulation parts is important to guarantee the reliability of the power supply.The catenary insulation parts contain much insulator which is over 95%.The stand or fall of insulator performance is directly related to the reliability of catenary power supply.Reasonably selecting a better technical and economic effect and the intensity of labor method for insulator monitoring,that the railway power supply department in the aspect of insulator cleaning establish a scientific,accurate and timely cleaning solution is into a prominent research topics.On the issue,research the application of high voltage power grid insulation online monitoring technology of several cities in China deeply and look up a large amount of instance data.Researching and analyzing the insulator smudgy monitoring method of the whole railway system power supply.Researching and discussing particularly the insulator filth on-line monitoring technology of railway power supply catenary.First of all,analyzing the insulator dirt monitoring method of the current railway power supply departments at this thesis.Summarizes the deficiency existing in the current technology.Researching and discussing the feasibility,applicability,scientific of insulator filthy on-line monitoring technology on the railway power supply catenary from the point of technology.According to the concept of science and technology ensure the safety.In compliance with the principles of advanced technology,reasonable economy,intelligent technology.To do the selection and optimization,and software development for catenary insulator on-line monitoring device.To do the field test and revision of technical parameters.Formulate insulator impurity reference level.To provide important reference gist for catenary insulator cleaning of railway power supply system.
