Abstract

The invention belongs to the field of overhead transmission lines, in particular relates to transverse l-shaped alternate anti-oscillation hardware. The transverse l-shaped alternate anti-oscillation hardware comprises a composite insulator 1 and a sub-conductor spacer 2, wherein one end of the composite insulator 1 is hinged with the sub-conductor spacer 2 through a ZBD-type hanging board; the other end is hinged with the sub-conductor spacer 2 through a right-angle hanging board 4; and a turn buckle 5 is arranged between the right-angle hanging board 4 and the sub-conductor spacer 2. The anti-oscillation hardware can realize stepless adjustment of length and the flexibility of rotation, and has the advantages that: the structure is compact, the anti-oscillation hardware is convenient to install and operate and the application range is wide.

Description

technical field [0001] The invention belongs to the field of overhead power transmission lines, and in particular relates to an in-line anti-dancing fitting. Background technique [0002] Ice-coated galloping of overhead transmission line conductors has always been a thorny problem that seriously threatens the safe and stable operation of transmission lines. When the ice-covered conductor dances, the conductors of each phase will vibrate irregularly with different waveforms and different phases, and it is very easy to cause phase-to-phase or phase-to-ground air breakdown flashover (especially for compact transmission lines). Vicious accidents of damage to line fittings, ground wires, pole towers, etc., galloping have brought great harm to the safe operation of transmission lines. [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 ...

Problems solved by technology

When the ice-covered conductor dances, the conductors of each phase will vibrate irregularly with different waveforms and different phases, and it is very easy to cause phase-to-phase or phase-to-ground air breakdown flashover (especially for compact transmission lines). Vicious accidents of damage to line fittings, ground wires, pole towers, etc., galloping has brought great harm to the safe operation of transmission lines

[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
