Anti-corona aluminum tube spacer bar

Abstract

The invention provides an anti-corona aluminum tube spacer bar. The anti-corona aluminum tube spacer bar consists of a wire clamp 1a and a wire clamp 1b which are same completely and are inverted oppositely. The anti-corona aluminum tube spacer bar is characterized in that the wire clamp 1a and the wire clamp 1b are hook-shaped wire clamps, two ends of the wire clamp 1a and two ends of the wire clamp 1b are circular arcs same in radius, the length of the circular arcs at one end are 3 / 4 of circumference length, and the length of the circular arcs at the other end are 1 / 4 of circumference length. The thickness of the wire clamp 1a and the wire clamp 1b is identical to the radius of the circular arcs. The circular arcs at two ends of the wire clamp 1a and at two ends of the wire clamp 1b form a round hole 4a and a round hole 4b which are used for installing aluminum tubes, and the opening positions of the round hole 4a and the round hole 4b are located at the upper portion and the lower portion of the anti-corona aluminum tube spacer bar. Compared with the prior art, the anti-corona aluminum tube spacer bar is good in anti-corona performance, simple in structure and convenient to install. A water discharging port is reserved to prevent water accumulation. In addition, functions of spacing, suspension and heavy hammer installation can be achieved.

Description

technical field [0001] The invention relates to an anti-corona aluminum tube spacer, in particular to an anti-corona aluminum tube spacer for an overhead transmission line, belonging to the technical field of overhead transmission line hardware. Background technique [0002] Jumper wires are used to connect the tension sections of high-voltage transmission lines. When the voltage level is low, the wires of the adjacent tension sections are generally connected by flexible wires; as the voltage level increases, the sag of the jumper also increases, in order to meet the electrical requirements of the tower body after the jumper is wind deflected. gap, the length of the cross-arm of the tower needs to be lengthened. Therefore, reducing the jumper sag and its windage offset is an effective way to reduce the size of the strain tower, and the jumper sag and offset are mainly determined by the jumper or the way of fixing the jumper. In order to reduce the size of the tower head as...

AI Technical Summary

Problems solved by technology

The aluminum tube jumper is mainly composed of several parts: aluminum tube, aluminum tube joint, aluminum tube spacer, suspension spacer, heavy hammer, aluminum tube terminal drainage fittings, drainage clamp, jumper insulator string, etc., rigid The part is composed of two parallel aluminum tubes. In order to maintain the distance between the aluminum tubes and facilitate the suspension, aluminum tube spacers are used. The opening of the ordinary aluminum tube spacers currently used is at the middle of the outer side of the aluminum tubes. The opening of the aluminum tube spacer is prone to visible corona during the operation of the UHV transmission line, which will cause corona power loss, radio interference, TV interference and noise interference
