A composite insulator

Abstract

The invention relates to a combined insulator and belongs to the technical field of high-voltage line auxiliary parts. The invention solves the problems that the existing insulators have insufficient tensile strength and physical resistance needs to be improved. The invention includes an insulator body for electrical isolation; positioning platforms arranged on both sides of the insulator body for clamping and positioning; a strengthening ring that becomes an internal reinforcing rib between the positioning platforms; The shed shed on the outside of the insulator body and the reinforcing ring and provides protection for it; the lightning protection voltage ring set on the outside of the positioning platform for lightning protection; the positioning platform on the front side is provided for fixing high-voltage lines The mounting seat; the positioning platform on the rear side is provided with a fixing seat for installing and positioning the insulator; the reinforcing ring is evenly provided with a plurality.

Description

technical field [0001] The invention relates to a combined insulator and belongs to the technical field of high-voltage line auxiliary parts. Background technique [0002] The transmission line is an important part of the power system and the main artery of the power system, used to connect the power grid and transmit electric energy. Transmission lines often need to be exposed to the wild, and even need to cross mountains and wilderness and extend vertically and horizontally. The probability of being attacked by lightning during thunderstorm season is high. Line lightning protection has always been a key and difficult issue in the industry. At the same time, transmission lines also require better support, which can be exposed for a long time without being corroded and oxidized. At present, transmission lines generally use insulators for lightning protection and strength support. Insulators require high strength and need to be used for a long time and support high-voltage li...

AI Technical Summary

Problems solved by technology

If under the specified operating voltage, lightning overvoltage and internal overvoltage, there will be no breakdown or flashover along the surface; under the specified long-term and short-term mechanical load, no damage or damage will occur; After long-term operation under electric load and various environmental conditions, there will be no obvious deterioration: At present, most insulators are directly cast, and it is often difficult to replace and replace parts. At the same time, the effect of anti-electricity and mechanical properties need to be further improved.
