Description
Technical field
The utility model belongs to the technical field of electric power system, specifically, relates to a kind of overhead rigid suspension contact system electricity segmental structure.
Background technology
At present, in the track traffic electric power system, overhead contact system all is to adopt built on stilts flexible suspension, at overlap and track switch place, the gravity type boat davit compensation of casting anchor need be set, it is big to take up room, for the high capacity track traffic, need to use catenary and auxiliary feeder, complex structure, and the load to civil engineering structure requires height, and the line service amount is big.
Summary of the invention
In order to overcome in the current track traffic electric power system, the shortcoming of built on stilts flexible suspension contact net system, the present utility model provides a kind of overhead rigid suspension contact system electricity segmental structure, it is a kind of electric segmented model that is suitable for built on stilts " Π " shape rigid suspension catenary of track traffic, it is simple in structure, safe and reliable, the anxiety little, that contact line conducting wire does not have axial force, nothing broken string, easy for installation that takes up room safeguard that the pantograph-catenary current collection characteristic is good easily.This up-to-date technology has been filled up domestic blank, is flowed in Chinese track traffic in the development of technology to have epoch making significance, has obtained substantial economics and social benefit.
The technical solution of the utility model is achieved in that overhead rigid suspension contact system electricity segmental structure, comprises parts such as bus duct, online lead-in wire, disconnector, section insulator, online switch; Near two bus duct anchor section ends traction substation are provided with another bus duct, form the segmentation of insulated overlap electricity, this another bus duct and above-mentioned two bus ducts are arranged in parallel, be separated by 300 millimeters, and one of them of another bus duct and above-mentioned two bus ducts is connected with the online lead-in wire, has disconnector on the online lead-in wire; Between two bus duct anchor section ends on the connection wire and the line of turning back, breaking insulator is set, forms electric segmentation.
Between two online switches of electric segmentation, the over zone feeding switch is set, can realizes over zone feeding in case of necessity.
The utility model is simple and reliable, and function realizes convenient, and cost is low, and easy for installation, can guarantee that motorcycle pantograph steadily passes through.
