Chinese standard contact network system

Abstract

The invention provides a Chinese standard contact network system which is formed by mutually connecting a plurality of anchor sections. Each two anchor sections are connected to form an anchor sectionjoint, an electrical connection device is arranged at each anchor section joint, a central anchor device is arranged in the middle of each anchor section, each anchor section comprises a force bearing rope, a contact line arranged below the force bearing rope, a plurality of forward positioning columns and a plurality of reverse positioning columns, a plurality of integral droppers are connectedbetween each force bearing rope and the corresponding contact line, and two ends of each force bearing rope and the corresponding contact line are connected with an anchor lowering compensation device. The system is excellent in performance, capable of meeting using requirements of contact networks of 400km, 350km, 250km, 200km and 120km per hour, convenient in part combining and easy in part replacement and has application prospect of unifying and standardizing contact network systems.

Description

technical field [0001] The invention belongs to the field of contact nets. Background technique [0002] By the end of 2017, the operating mileage of my country's electrified railways reached 87,000 kilometers, including 25,000 kilometers of high-speed railways. The scale of the road network continues to expand, which puts forward higher requirements for the catenary equipment. my country's electrified railway catenary has various installation types, complex structures, and various parts specifications. Under the same use conditions and functional requirements, the types and types of parts and components reach several or even dozens of types, which are suitable for design, construction, manufacturing, operation and maintenance and industry. Management brings great difficulties, it is difficult to improve the overall quality of the project from the source, and there are still problems such as the low service performance of individual parts and the use of foreign standards and...

Problems solved by technology

my country's electrified railway catenary has various installation types, complex structures, and various parts specifications. Under the same use conditions and functional requirements, there are several or even dozens of types and types of parts and components. Management brings great difficulties, it is difficult to improve the overall quality of the project from the source, and there are still problems such as the service performance of individual parts is not high, and the materials of some parts follow foreign standards and grades, etc., to develop a catenary with uniform parts and excellent performance The system needs to be solved urgently
