According to the development direction of intelligent traction power supply system and the trend of information digitalization of catenary,a new intelligent catenary architecture is designed.A new type of fiber-optic composite load-bearing cable is researched and developed,which solves the connection problem of this type of load-bearing cable at the joint of anchor section and develops the corresponding device mechanism.On the basis of theoretical analysis of distributed monitoring technology,through mathematical analysis and laboratory verification,the wide-area monitoring and early warning technology of intelligent catenary real-time state based on wide-area optical fiber sensing technology and optical fiber composite load-bearing cable is studied.In the National Railway Test Center,a real-life test verification platform has been set up,which proves the feasibility of the technology and the feasibility of the project.
