Problems solved by technology

[0004] Among the relevant patents that have been applied in China, the patent "A Glass Insulator" (application number: 201210349297.3, publication date: 2013-01-16) discloses a composition formula of a glass insulator with good stability, but due to the Sintering after powder, high brittleness and poor bonding force, unable to retain basic working performance after zero-degree self-explosion, and because the powder remelting destroys the tempering effect and surface compressive stress brought by rapid cooling of the glass, the mechanical properties are poor and The service life is short (the surface compressive stress can significantly improve the service life), on the other hand, there is no toughening agent added, so the glass insulator has

Abstract

The invention discloses a toughened glass insulator and a fabrication method thereof. The insulator at least can resist lightning steep slope peak 6,000kV/s and can stand repeated circulation impact of -50 to 50 DEG C in a standard load condition, a standard load can be still supported after self explosion at 0 DEG C, the surface pressure stress is not lower than 150Mpa, the impact strength of an U-shaped gap is not lower than 20J/cm<2>, and the light transmittance is not lower than 98%. On the basis that lead glass belonging to toughened glass, lanthanum oxide and bismuth oxide which are used for improving chemical stability and light transmittance of glass are added, zirconium oxide and titanium oxide which are used for improving acid and alkali resistance, light transmittance and radiation protection capability of the glass are also added, and the toughened glass insulator is finally fabricated through tempering under the protection of nitrogen. The toughened glass insulator has the advantages of good electrical property, high automatic fracture toughness, high light transmittance, good integrated mechanical property, long service lifetime and good economy.

Description

technical field [0001] The invention relates to the field of electronic components, in particular to a toughened glass insulator and a manufacturing method thereof. Background technique [0002] An insulator is a special insulating control that can play an important role in overhead transmission lines. [0003] In the early years, insulators were mostly used for utility poles, and gradually developed in the high-voltage wire connection tower with a lot of disc-shaped insulators hanging at one end. It is to increase the creepage distance, usually made of glass or ceramics, called insulators. Insulators play two basic roles in overhead transmission lines, namely supporting wires and preventing current from returning to the ground. These two roles must be guaranteed; at the same time, insulators should have sufficient electrical insulation strength, moisture resistance and high temperature resistance. [0004] Among the related patents that have been applied for in China, the ...
