Damping spacing bar clamped more firmly

Abstract

The invention provides a damping spacing bar clamped more firmly, and relates to the technical field of high-voltage electricity power fittings. The damping spacing bar comprises a square supporting part and four wire clamps arranged on the square supporting part, wherein the wire clamps are in a hook shape, hooks of two wire clamps at the upper end of the square supporting part face downwards, hooks of two wire clamps at the lower end of the square supporting part face upwards, and the wire clamps on the same side are connected through a connector. The damping spacing bar is simple in structure and reasonable in design, and by means of the hooks opposite in pairs, the spacing bar is prevented from falling off to a certain degree and stability is enhanced; meanwhile, upper and lower wires are tensioned to a greater degree through the connector on the same side under the circumstance that the damping spacing bar does no fall off, the damping spacing bar is clamped on the wires more forcefully and is not prone to shaking, and damage to the wires is reduced.

Description

Technical field: [0001] The invention relates to the technical field of high-voltage electric fittings, in particular to a more firmly clamped damping spacer bar. Background technique: [0002] Wire splitting is a wire erection method adopted by the ultra-high voltage output circuit to suppress corona discharge and reduce line reactance, that is, each wire is composed of several sub-wires with smaller diameters, and each sub-wire is spaced at a certain distance and arranged in a symmetrical polygon. arrangement. The spacer is the main fitting in the split wire structure. There are three, four, five and six main types in different applications. The basic tasks of the spacer are: (1) to suppress the vibration of the breeze (2) to prevent the whip between the wires Hit (3) to suppress the vibration of the second gear. At present, the damping spacer is used most, which has better vibration-absorbing performance than the rigid spacer. [0003] However, in use, due to the vibra...

[0003] However, in use, due to the vibration of the wire caused by the breeze and the vibration of the sub-gap caused by the strong wind, the right angle will cause the wire to fatigue and be damaged, and it is more likely to loosen the fastener and indirectly cause the wire to wear. The damping spacer uses the elasticity of the rubber element to obtain all Stiffness required to allow full mobility while maintaining split wire geometry
