Description

Six-split high-strength spacer

Technical Field

The utility model belongs to the technical field of power transmission and transformation gold utensil is made, in particular to six split high strength conductor spacers.

Background

The conductor spacer used at present can be divided into five types for two, three, four, six and eight conductors according to the grades of the power transmission and transformation circuit and the number of the split conductors. The normal use of the spacer is related to the operation safety of the transmission line. However, the line conductor is subjected to wind force and the like under natural conditions, so that the insulator and the spacer are easily damaged due to the fact that the conductor is easily subjected to string movement (waving, breeze vibration and the like) and twisting movement, and potential safety hazards are brought to a power transmission line.

Due to the fact that wind power acts on the tensile load of the spacer, the spacer is not stressed uniformly, corresponding anti-skidding structures are absent in the places where the wires are in contact with the spacer, or the anti-skidding structures are unreasonable in design, so that the anti-skidding structures are separated, the spacer is finally caused to slide and move on the wires, the relative distance between the split wires is changed, discharging tripping is caused, and after the spacer is waved for a long time, a line fitting, an insulator, the wires, a pole tower and the like are damaged, and the most serious power transmission accident is caused.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects existing in the prior art, the utility model provides a simple structure, six divisions high strength conductor spacer of reasonable in design.

The utility model provides a specific technical scheme does: the utility model provides a six split high strength conductor spacers, its includes hexagon center frame and fastener body, hexagon center frame has six installation angles, and every ann corner passes through cross axle sleeve and evenly distributed's six fastener body near-end fixed connection, hexagon center frame and six fastener body near-ends correspond the department and open there is the arc slotted hole, fastener body near-end still simultaneously with through round pin hub connection between the arc slotted hole of this frame, fastener body distal end is the type hemisphere, and its outside is smooth curved surface, and inboard half wall hole for making the wire pass through, half wall hole is downthehole to inlay and is equipped with the rubber pad, the rubber pad is the semicircle form, two tip that the rubber pad upper surface is close to the semicircle form all are equipped with the anticreep arch, half wall hole's relevant position has seted up the corresponding cross slot with the anticreep arch.

Further optimization and improvement of the scheme are as follows: the spacer is made of high-strength aluminum alloy.

Further optimization and improvement of the scheme are as follows: and the outer side of the wire clamp body is also provided with two preformed armor rod mounting bosses.

Further optimization and improvement of the scheme are as follows: and a rubber column and a gasket are arranged between the cross shaft sleeve and the frame to increase damping.

Compared with the prior art, the utility model discloses the beneficial effect who brings does: the utility model can effectively prevent the spacer from sliding on the conductor by additionally arranging the rubber pad in the semi-wall hole, so that the spacer can more stably support the split conductor; secondly, the anti-falling bulge is arranged, so that the rubber pad can be effectively prevented from falling off from the half-wall hole; the high-strength aluminum alloy is adopted as a material, has the characteristics of small density, high strength, good processing performance, excellent welding performance and the like, improves the performance of the spacer, and prolongs the service life of the spacer.
