Abstract

The invention relates to the technical field of porcelain insulators, and provides a toughening column type porcelain insulator and a preparation method thereof. The insulator is provided with an insulator body and an insulating layer, and a base material, a filler and a pore forming agent are adopted, so that it is ensured that sintered ceramic contains some fine open pores, the combination of the insulator body and other insulating materials is facilitated, and the strength of the insulator body is not affected; the insulator body is soaked in insulating slurry to obtain the insulating layer, so that the air holes are closed, the strength is ensured, and the insulating property is also improved. By using the raw material with relatively high Al2O3 content, the structure of the obtained insulator is more compact, the stress concentration of the insulator is effectively reduced, and the strength of the insulator is improved; zirconium oxide composite nanoparticles are added to serve as a dispersion phase to reinforce and toughen a matrix, so that the fracture toughness and bending strength of the insulator are improved; and by adding a water reducing agent, the fluidity of the slurry is enhanced, and the surface quality of the sintered insulator is ensured.

Description

technical field [0001] The invention relates to the technical field of porcelain insulators, in particular to a toughened column type porcelain insulator and a preparation method thereof. Background technique [0002] An insulator is a device installed between conductors of different potentials or between a conductor and a component at ground potential, capable of withstanding voltage and mechanical stress. An insulator is a special insulation control that plays two basic roles in overhead transmission lines: it is used to support and fix the busbar and live conductors, and to provide sufficient distance and insulation between live conductors or between conductors and the earth. Insulators are used to increase the creepage distance, commonly used are porcelain insulators and fiberglass insulators. The high-voltage insulators used in high-voltage transmission lines have the following requirements: they are divided into electrical load and electrical performance requirements,...
