Overhead line system additional wire suspension device and overhead line system strut device

Abstract

The invention relates to the technical field of railway electrification overhead line systems, and provides an overhead line system additional wire suspension device and an overhead line system strutdevice. The overhead line system additional wire suspension device comprises an insulator (10), a long hanging ring (20) and a wire clamp device (30) used for clamping an additional wire, wherein theinsulator (10) is rod-shaped, one end of the insulator (10) is provided with a mounting surface (11), the mounting surface (11) is perpendicular to the axial direction of the insulator (10), the other end of the insulator (10) is connected with the long hanging ring (20), and the bottom end of the long hanging ring (20) is connected with the wire clamp device (30). The rod-shaped insulator not only plays a role in insulation and isolation, but also plays a role in supporting, so that the insulator can be mounted on a strut of the overhead line system through the mounting surface, an insulatorstring is not required to be arranged any more, the swinging of the additional wire caused by the insulator string is avoided, and fatigue of the additional wire and abrasion of connecting parts arerelieved.

Description

technical field [0001] The invention relates to the technical field of railway electrification catenary, in particular to a catenary additional wire suspension device and a catenary support device. Background technique [0002] In order to improve the capacity of railway transportation, comprehensively utilize power resources, reduce environmental pollution, and achieve the purpose of less investment and better results, my country has accelerated the construction of electrified railways, especially the construction of high-speed railways. The catenary positive feeder, power supply line and reinforcement line are important components of the electrified railway traction power supply system. The traction substations, switching stations, and divisional stations distributed along the line all have several kilometers of power supply lines. Parallel lines and reinforced lines are installed on lines with long power supply arms, steep slopes, and many roundabouts; AT power supply mod...
