Composite material light energy-saving conductor spacer

Abstract

The invention discloses a composite material combination type light energy-saving conductor spacer, which is formed in the way that a frame (1), a cross shaft sleeve (3), a wire clip body (4) and a cover plate (7) are all made of fiber composite materials on the basis of a common conductor spacer. The conductor spacer adopts the fiber composite materials and a specially optimized structure, does not generate hysteresis lag or eddy-current loss, does not generate corona, is free of corona noise and electromagnetic energy loss, and is obvious in energy saving effects. The conductor spacer is high in mechanical strength, stable in grip power, waving resistant and small in maintenance cost. By means of special optimized structure design, the conductor spacer effectively prevents abrasion caused of connection of different materials of connection joints, improves abrasion resistance, prolongs service life, is light in weight and convenient to construct and install, saves electric energy and is remarkable in economical and social benefits.

Description

technical field [0001] The invention relates to a spacer bar, in particular to a lightweight energy-saving spacer bar made of composite material. Background technique [0002] In overhead power transmission and transformation lines, traditional cast iron spacers cannot solve the problems of bulkiness, large hysteresis and eddy current loss, corona and noise. In order to solve the above problems, the development demand for a new generation of lightweight energy-saving spacers is becoming more and more Urgent, and there are many new technologies and new products. Among them, a number of related Chinese invention patents and utility model patents for spacers have been disclosed. Their structural materials are different, and to a certain extent, they achieve the purpose of energy saving and circuit protection. The Chinese Patent Publication No. is CN101447657A, and the invention patent titled "Polymer Alloy Buffer Type Lightweight Spacer" discloses a spacer formed by precision...

Problems solved by technology

There are two problems in this method: first, polyamide is more expensive and difficult to promote, and this material can be recycled, but in view of the special geographical environment where electric power fittings are located, the recyclable amount is small and difficult to recycle Second, the non-magnetic steel used in this electric power fitting is difficult to produce and has not been widely promoted

The Chinese patent publication number is CN1560876A, and the invention patent named "Ultra-high voltage transmission line spacer rubber damping part" uses EPDM rubber to replace iron components. Ethylene propylene rubber has low cohesive energy due to the lack of active groups in its molecular structure. In addition, the rubber material is easy to bloom, and the self-adhesiveness and mutual adhesion are very poor. After treatment, the vulcanization speed and adhesive performance of ethylene-propylene rubber can be improved, but the mechanical strength is reduced.

Existing materials only solve part of the problem, only belong to the experimental stage, and have no practical application
