Problems solved by technology

[0002] Traditional disk insulators are glued together with iron caps, steel feet, and porcelain or glass core disks with cement glue. Similarly, when the insulator is subjected to cold and heat changes, the porcelain or glass parts are subject to greater compressive stress and shear stress, so the insulating part is easy to open or be broken down to form a zero-value insulator
The zero-value detection of ceramic core insulators must be inspected one by one on the tower, which requires a lot of manpower and material resources, and the accuracy is not high, so that there are hidden dangers of accidents caused by lightning strikes and pollution flashovers in the line, and the glass core will self-explode , needs to be replaced by climbing the tower, considering the comprehensive consideration of manual inspection, replacement cost and power failure loss caused by power failure, the comprehensive price will continue to rise with the increase of operating time

Abstract

The invention discloses a disc-shaped suspension type composite insulator and a manufacturing method thereof, the disc-shaped suspension type composite insulator comprises a steel foot, a cylindrical head, a core disc and an iron cap are sequentially arranged on the outer side of the upper portion of the steel foot, the lower portion of the core disc is connected with an umbrella skirt, and the disc-shaped suspension type composite insulator is characterized in that the cylindrical head and the core disc are of an integrated structure. The beneficial effects are that the problems that the iron cap and the steel leg need to be maintained in a water pool, the process is tedious and the yield is low when the iron cap and the steel leg are cemented into a whole through a cement adhesive in the prior art are solved, the one-time forming process is simple, the yield is high, the weight is light, and the safe operation of a power grid is better ensured.

Description

technical field [0001] The invention relates to the technical field of insulators for transmission lines, in particular to a disk-shaped suspension composite insulator and a manufacturing method thereof. Background technique [0002] Traditional disc insulators are glued together with iron caps, steel feet, and porcelain or glass core discs with cement adhesive. Similarly, when the insulator is subjected to cold and heat changes, the porcelain or glass parts are subject to greater compressive stress and shear stress, so the insulating part is easy to open or be broken down to form a zero-value insulator. The zero-value detection of ceramic core insulators must be inspected one by one by climbing the tower, which requires a lot of manpower and material resources, and the accuracy is not high, so that there are hidden dangers of accidents caused by lightning strikes and pollution flashovers in the lines, and the glass core will self-explode , It needs to be replaced by climbi...
