Embodiment Construction

[0056] An embodiment of the present invention is described in conjunction with accompanying drawings 1, 2, 3, 4, 5, 6, 7, 8, 9, 10.

[0057] A high-speed electrified railway catenary system is formed by interconnecting multiple anchor sections. Each anchor section includes a wrist arm positioning device 34 , an anchor compensating device 35 , an electrical connection device 36 , a string hanging device 37 , a central anchoring device 38 and a wire fork 39 . The lower anchor compensation device 35 is arranged at both ends of each anchor section, the central anchor knot device 38 is arranged at the middle of each anchor section, and the electrical connection device 36 is arranged on the inner side of the lower anchor compensation device 35, between the lower anchor compensation device 35 and the center. Between the anchoring devices 38 , each anchor segment is provided with a plurality of arm positioning devices 34 and string hanging devices 37 . The distance between two adjace...

Abstract

The invention is concerned with a contact net system of high-speed electrical railroad made of some anchoring segments connecting with each other. Each anchoring segment relates to positioning device to wrist and arm, anchoring compensator, electric connecting equipment, suspension bowstring equipment and mid-point anchor equipment. The anchoring compensator sets at the two ends of each anchoring segment and the mid-point anchor equipment sets at the middle part of each anchoring segment. The connecting equipment of electricity sets at the inside of anchoring compensator and between the anchoring compensator and mid-point anchor equipment. Each anchoring segment has some positioning devices to wrist and arm and suspension bowstring equipments. It is fit to sustain, suspend, locate, machine, electric connecting and terminal anchoring to contact net system of electrical railroad with 200km / h, 50Hz single-phase and 25kV alternating current.

Description

technical field [0001] The utility model relates to a high-speed electrified railway catenary system, which is suitable for the high-speed electrified railway system with an hourly speed of 200km / h. Background technique [0002] In the early stage of the development of catenary components for electrified railways, they only simply meet the needs of safe operation, and the tension of catenary wires and catenary cables is relatively small: the catenary cable of the main line is 14.7kN; the contact line of the main line is 8.5kN; the catenary parts are all separate Design, production, and use do not consider the system relationship between various products, such as mutual cooperation. The parts are designed by different design units and manufactured by different production units. When used, they are installed and matched by the construction unit to form a system. There are many unreasonable factors in the interface between products, which affect the flow quality and running spe...
