Anti-oscillation interphase hardware tool for double bundle conductor

Abstract

The invention belongs to the field of overhead power transmission lines, in particular to an anti-oscillation interphase hardware tool for a double bundle conductor. The anti-oscillation interphase hardware tool for the double bundle conductor comprises a compound insulator, sub-lead spacers and grading rings, wherein one end of the compound insulator is hinged with one sub-lead spacer by a ZBD-type clevis, and the other end thereof is hinged with the other sub-lead spacer by a right-angle clevis; a turn buckle is arranged between the right-angle clevis and the sub-lead spacer, and the two ends of the compound insulator are respectively provided with one grading ring. The anti-oscillation interphase hardware tool realizes the stepless adjustment of length, can avoid the defect that a bulb falls out, and has the advantages of better stress intensity, more flexible rotation, compact structure, convenient installation and operation, wide applicable scope and the like.

Description

Technical field [0001] The invention belongs to the field of overhead power transmission lines, and particularly relates to an anti-galloping fitting for two split conductors. Background technique [0002] Icing and galloping of overhead transmission lines has always been a thorny issue that seriously threatens the safe and stable operation of transmission lines. When the wire is icing and dancing, the wires of each phase will have different waveforms and irregular vibrations of different phases, and it is very easy to cause interphase or relative air breakdown flashover (especially for compact transmission lines). Long dancing time will cause power transmission. Vicious accidents such as damage to line fittings, ground conductors, poles, etc., galloping have brought great harm to the safe operation of transmission lines. [0003] The existing interphase spacer rod matching connection fittings can only achieve a few length adjustments, and cannot achieve stepless adjustment. Moreo...

AI Technical Summary

Problems solved by technology

[0003]The existing interphase spacer matching connecting fittings can only realize the adjustment of several lengths, and cannot realize stepless adjustment, and most of the connecting fittings use balls when connecting insulators. The connection method of the head ball socket is prone to the phenomenon that the ball head falls off during the line operation, and there are safety hazards in construction

For example, the Chinese utility model patent with the notification number CN201243187Y discloses an adjustable conductor interphase spacer. An adjustment plate and a connecting plate are arranged between the insulator end fittings. By adjusting the fixed position of the adjustment hole on the adjustment plate, it can adapt to And to make up for the error of wire sag installation, but because this kind of connecting fitting adopts the structure of the adjustment hole, there will still be a blind area in the adjustment, so when the phase spacing of the wire needs to be fine-tuned, the spacer is still not competent, and This structure is mainly used in multi-split conductors. Due to the special structure of the fittings used in the two-split conductors, the interphase spacer is not suitable for two-split conductors; in addition, most of the spacers and insulators in the prior art use spherical hinges. connection, but the ball joint connection is prone to the phenomenon that the ball head falls off when the line is running, and the rotation is not flexible enough. Therefore, it is urgently needed for those skilled in the art to develop a device that can not only steplessly adjust the interphase spacing of the sub-conductors, but also has high Safe one-shaped interphase anti-dancing fittings, which can be used in various split forms, especially for two split sub-conductors
