Problems solved by technology

However, in long-distance, high-altitude, high-cold regions, strong icing, complex terrain and climate conditions, the probability of encountering icing on lines is very high, which will lead to deformation, cracking and aging of composite insulators, degradation of electrical performance, and prone to ice flash and pollution. Lightning accidents seriously endanger the safe operation of transmission lines, which is a very important and arduous challenge

Abstract

The invention relates to a semiconductor anti-thunder ice combined porcelain insulator which is formed by combining an anti-thunder ice cover and a ceramic column type insulator. The anti-thunder ice cover is coated with metal oxide semiconductor glaze, and the metal oxide semiconductor glaze is formed by adding a certain amount (about 30%-35%) of conductive metal oxide tin, nickel and chromium into common electric porcelain glaze, so that the anti-thunder ice cover has special electric energy heat conduction performance, the surface resistivity is 100-110 ohms, and the surface resistivity is between an insulator and a conductor. According to the present invention, heat is generated at a normal temperature of 25-30 DEG C through the current of an overhead line, the surface voltage heat is uniformly distributed, snow and rain cannot stay, and the surface of a needle cover is always kept dry, so that the special structure of the insulator has the advantages of high insulation, high stain resistance, high strength, high durability and extremely high effect of improving an effective value of wet flashover withstand voltage of ice, snow and rainstorm, and the reliability of power transmission safety of a power grid line is ensured.

Description

technical field [0001] The invention relates to the technical field of power equipment for power transmission and transformation empty rack lines, in particular to a semiconductor lightning protection and ice combined porcelain insulator for electrical components. Background technique [0002] The future power grid will develop towards a smart grid. Based on the UHV power grid as the backbone grid and the strong power grid with coordinated development of power grids at all levels, use advanced communication, information and control technologies to build a network centered on informatization, automation and interaction. The characteristic intelligent grid ensures the safety and reliability of power supply. However, in long-distance, high-altitude, high-cold regions, strong icing, complex terrain and climate conditions, the probability of encountering icing on lines is very high, which will lead to deformation, cracking and aging of composite insulators, degradation of electri...
