Enhanced composite insulator umbrella skirt sheath

Abstract

The invention provides an enhanced composite insulator umbrella skirt sheath, which consists of the following ingredients in parts by mass: 95 to 105 parts of methyl vinyl silicone rubber, 4 to 6 parts of ferric oxide, 4 to 6 parts of hydroxy silicone oil, 1.5 to 2.5 parts of sulfurizing agents, 58 to 77 parts of ceramic powder, 62 to 83 parts of aluminum hydroxide and 1 to 3 parts of coloring agents. The ceramic powder is proportionally added in the umbrella skirt sheath, and the ceramic powder is obtained through crushing the recovered waste and abandoned ceramic insulator ceramic bodies and processing the recovered waste and abandoned ceramic insulator ceramic bodies into powder. The ceramic powder is added into the umbrella skirt sheath to be used as reinforcing agents for totally replacing white carbon black and partially replacing aluminum hydroxide, and the mechanical intensity and the electric performance of the silicon rubber can be improved. The waste and abandoned ceramic insulator ceramic bodies are effectively utilized to be used as raw materials for producing the umbrella skirt sheath, the reasonable cyclic utilization of the resources are realized, and good economic benefits and environment benefits are realized.

Description

technical field [0001] The invention relates to an electrical component, in particular to a shed sheath of a reinforced composite insulator for a power transmission line, and belongs to the technical field of electric power. Background technique [0002] The line insulator is one of the main components of the transmission line. Its function is to support the wire, prevent the current from returning to the ground, and increase the creepage distance. Its performance has an important impact on the safe and stable operation of the power grid. Line insulators are mainly divided into three categories: composite insulators, ceramic insulators and glass insulators. From the perspective of market application, although composite insulators are a rising star, they are showing an increasing trend year by year both in terms of output and voltage level. Composite insulator is a new type of insulator with rapid development. It has many advantages, such as small size, light weight, small s...

Problems solved by technology

Due to the large intermolecular distance and weak intermolecular force of silicone rubber, the mechanical strength of silicone rubber itself is not high, and the hardness and wear resistance are poor. cause economic loss

[0004] At present, the insulators used on power lines will be considered for full-line replacement if their service life reaches 20 years. A considerable part of the replaced insulator
