Improved stay insulator

Abstract

The invention belongs to the technical field of power equipment, and particularly relates to an improved stay insulator which comprises an umbrella skirt and a fixing fitting. The fixing fitting comprises two mounting plates, incomplete gears, racks and internal threaded cylinders are mounted on the mounting plates, and threaded rods are rotatably mounted in the internal threaded cylinders; mounting cylinders are fixedly connected to the incomplete gears, a plurality of threaded holes are evenly formed in the mounting cylinders in the circumferential direction of the mounting cylinders, threaded columns in the radial direction of the mounting cylinders are mounted in the threaded holes in a threaded fit mode, and arc-shaped plates are rotatably mounted at the inner ends of the threaded columns; rubber strips matched with the surfaces of stay wires are fixedly arranged on the inner surfaces of the arc-shaped plates, and guide rods which are parallel to the threaded columns and in sliding fit with the mounting cylinders are fixedly mounted on the outer surfaces of the arc-shaped plates. According to the improved stay wire insulator, the included angle between the stay wires at the two ends of an umbrella skirt can be adjusted, the stay wires can be limited after being fixed, friction between the stay wires and the arc-shaped plates during shaking is avoided, and it can be guaranteed that the tension progress of the stay wires is kept consistent all the time.

Description

technical field [0001] The invention belongs to the technical field of power equipment, and in particular relates to an improved guyed insulator. Background technique [0002] The guyed insulator is a special insulation control, including the shed and the fittings at both ends of the shed. The guyed insulator can play an important role in the overhead transmission line. Installing the stay wire insulator on the stay wire of the distribution line can effectively prevent the accidental electrification of the stay wire and realize the insulation between the stay wire and the ground. The existing guyed insulators have the following problems during use: (1) The angle between the guyed wires at both ends of the shed is always 180°, which cannot be adjusted according to the actual working conditions; (2) The ends of the guyed wires are wound on the fittings , when the cable itself is shaken by the wind force, there will be friction between the cable end and the hardware. Long-term...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides an improved guyed insulator, aiming to solve the following problems in the use of current guyed insulators: (1) The included angle of the guyed wires at both ends of the shed is always 180°, which cannot be adjusted according to actual working conditions ; (2) The end of the cable is wound on the hardware. When the cable itself is shaken by the wind force, there will be friction between the cable end and the hardware. Long-term friction will cause the strength of the cable end to be damaged, and seriously cause the cable end to be damaged. Falling off from the hardware; (3) When the pull wire is inevitably elongated or contracted by the external temperature, it will affect the tension of the pull wire
