Current-carrying adjustable integral hanger

Abstract

The invention belongs to an application device for suspending a contact wire on a catenary in an electrified railway contact net, in particular relates to a current-carrying adjustable integral hanger. The current-carrying adjustable integral hanger is characterized in that an aluminum hanger clamp (2) for the catenary is clamped and connected on an aluminum-clad steel aluminum stranded conductor catenary (1), a hanger clamp (9) for the contact wire is connected on a kufil alloy contact wire (10), the aluminum hanger clamp (2) for the catenary and the hanger clamp (9) for the contact wire are eudipleural structures, structural members are locked with each other by locking bolts (5), two ends of a copper-magnesium alloy hanger wire (6) are provided with a copper alloy connecting clamp (8) and a copper-aluminum transition connecting clamp (3), the copper alloy connecting clamp (8) penetrates the hanger clamp (9) for the contact wire and is fixed by a wire pressing tube (7); and the copper-aluminum transition connecting clamp (3) penetrates the aluminum hanger clamp (2) for the catenary and is fixed by the locking bolt (5). The current-carrying adjustable integral hanger can help solve the copper-aluminum transition between the aluminum hanger clamp for the catenary and the copper magnesium alloy hanger wire and avoid electrochemical corrosion between the copper and the aluminum.

Description

technical field [0001] The invention belongs to a device used when an electrified railway catenary is suspended on a catenary cable, in particular to a current-carrying adjustable body suspension string. Background technique [0002] At present, in some sections of my country's electrified railway catenary, the catenary cables are made of aluminum-clad steel-aluminum stranded wire, and the contact wires are copper-silver alloy contact wires. One is the non-current-carrying type, the suspension string is made of stainless steel suspension string, the suspension string clamp of the catenary cable is made of insulating sliding type or aluminum alloy material, and the suspension string clamp of the contact wire is made of copper alloy. This overall suspension string cannot carry current. The other is the current-carrying type, the suspension string is made of copper-magnesium alloy suspension wire, the suspension string clamp of the load-bearing cable is made of aluminum alloy, a...

Problems solved by technology

[0003] In order to overcome the defect that the copper-aluminum transition of the existing current-carrying suspension strings is prone to electrochemical corrosion, the present invention provides a current-carrying adjustable body suspension string, which can well solve the problems of the aluminum suspension strings of the load-bearing cables. The copper-aluminum transition problem between the clip and the copper-magnesium alloy suspension string avoids electrochemical corrosion between copper and aluminum
