Embodiment 1

[0037] like figure 1 As shown in the figure, a catenary suspension structure suitable for a large current carrying capacity electrified railway is formed by interconnecting several anchor sections, and the anchor sections include two supporting force cables 1, a suspension chord 2, a contact line 3 and a suspension point 4; The adjacent anchor segments are connected by anchor segment joints 5 .

[0038] The load-bearing cable 1 is supported by a plurality of the suspension points 4 , and the load-bearing cable 1 suspends the contact line 3 through the suspension string 2 . like figure 2 As shown, the load-bearing cable 1 and the contact wire 3 are electrically connected through a horizontal electrical connection 7; the upper end of the horizontal electrical connection 7 is respectively connected with the two support cable 1 through two wire clips, and the lower end is connected by a soft copper strand The wires are connected to the contact wires 3 .

[0039] like image 3...

Embodiment 2

[0044] The top view of the installation of the contact wire 3 and the bearing cable 1 is as follows Figure 5 shown, and the contact line 3 and the bearing cable 1 are arranged in broken lines along the length direction of the anchor section (ie the direction of the center line 9 of the pantograph) on the horizontal plane projection (that is, the suspension points 4 are sequentially distributed on the receiving The two ends of the pantograph center line 9); the suspension points 4 are arranged on the steel column, and the span between the adjacent suspension points 4 is not more than 55m. The vertical distance between the suspension point 4 and the contact line 3 is 950 mm.

[0045] The lower anchor compensation device 10 corresponding to the bearing cable 1 at the same end of each anchor segment and the lower anchor compensation device 10 corresponding to the contact line 3 are arranged at intervals, and the corresponding distance is 50m.

Abstract

The invention relates to the technical field of electrified railway contact net systems, in particular to a suspension structure suitable for a large-current-carrying-capacity electrified railway contact net. The number of the carrier cables in the overhead line system is increased, the multiple anchor sections are sequentially connected for combination, the structure is simple, the modular design facilitates establishment and maintenance, the construction and operation cost is reduced, and the defects in the prior art are overcome; therefore, the current-carrying capacity of the overhead line system is improved, and the situation that the requirement for clearance of a tunnel is increased due to the arrangement of a reinforcing line is avoided; meanwhile, system fault factors possibly generated due to the fact that a large number of electric connection, copper-aluminum transition wire clamps and the like are increased are avoided; therefore, the construction cost of an electrified railway is greatly reduced, and meanwhile, the reliability of the overhead line system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of an electrified railway catenary system, in particular to a catenary suspension structure suitable for a large-capacity electrified railway. Background technique [0002] With the rapid development of my country's electrified railway, the railway line has extended to the vast land of the motherland, the terrain is complex, and the transportation needs are different. Higher requirements are put forward for the running speed and traction quality of the train. Electrified railway has become an important direction of development. Electrified railways often have high traffic density and large slopes on the route. It is required that the catenary system that supplies power to running trains must have a high current-carrying capacity, which can guarantee a large current-carrying capacity of more than 1000A for 20 minutes. Based on the current standard single order The current-carrying capacity of the conductor ca...
