Overhead line system attach wire sliding insulation spacer device

Abstract

The invention discloses an overhead line system attach wire sliding insulation spacer device. The spacer device is arranged on a pre-hinged guard line (5), an attach wire (4) is arranged on the lower end, used for insulation between spacer wires; the spacer device comprises a steer wheel set (1), an insulation spacer (2) and a pre-hinged suspension clamp (3); the steer wheel set (1) is hung on the pre-hinged guard line (5) and is in sliding state, the top end of the insulation spacer (2) is connected in a hinged mode with the steer wheel set (1), the lower end of the insulation spacer (2) is connected in a hinged mode with the pre-hinged suspension clamp (3), the pre-hinged suspension clamp (3) is fitted in a clamping mode with the attach wire (4). The problem is solved when short circuit occurs because of inadequate insulation distance between two wires caused by the large swing amplitude of the vertically arranged attach wire of the electrification overhead line system of high speed railways in windy regions, the amplitude of vibration is effectively reduced, the strain of wires and the abrasion of the connection parts are eased, and the problems of contortion and the like by different displacements caused by different linear expansions due to different specifications of double diversion wires are effectively prevented by the slide mode design.

Description

technical field [0001] The invention relates to the technical fields of mechanical structure and traffic engineering, in particular to the technical field of railway electrified catenary, and in particular to a sliding insulating spacer device for additional conductors of the catenary. Background technique [0002] Ordinary area (the ordinary area here refers to the windless area, or the small wind can not affect the railway catenary, also known as the non-wind area) the railway catenary has two additional conductors of different voltages or the same voltage, and the double additional conductors of different circuits are vertical Arrangement, wind deflection will occur during operation, resulting in insufficient insulation distance. In the strong wind area in the northwest or in the AT power supply mode of the coastal railway, the vibration between the positive feeder and the protection line erected on the same pole is frequent. Often, the two additional wires vibrate greatl...

Problems solved by technology

[0006] The object of the present invention is to provide a sliding insulating spacer device for additional conductors of the catenary, which solves the large swing of the additional conductors vertically arranged in the electrified catenary of the high-speed railway in the windy area and the short circuit caused by the insufficient insulation distance between the two conductors. effectively reduce the vibration swing, alleviate the fatigue of the wire and the wear of the connecting parts, and the sliding design can effectively avoid the torsion caused by the difference in the amount of movement caused by the different specifications and different line expansions of the double support.
