Problems solved by technology

Most of the existing insulator manufacturers still follow the principle of proximity, using a relatively high proportion of low-quality clay, adding some quartz sand, and not adding or adding a very small amount of low-quality bauxite to produce suspension porcelain insulators. The result is: after firing The performance of porcelain is poor, the strength of porcelain is generally low, and the dispersion of porcelain insulators is large, which seriously threatens the safe operation of the power grid.

Abstract

The invention discloses a formula of high-strength porcelain for manufacturing of a suspension porcelain insulator. The high-strength porcelain consists of the following ingredients in parts by weight: 25-55 parts of clay, 10-45 parts of bauxite and 8-25 parts of feldspar, wherein clay consists of the following ingredients in parts by weight; 10-30 parts of ashtree clay produced in Shulan County, Jilin Province, 1-15 parts of Faku clay produced in Faku County, Shenyang Province, Zhongxin clay produced in Kuancheng County, Chengde City, 1-20 parts of Jiayao clay produced in Xinhui District, Jiangmen City, 1-10 parts of Guangdong white clay produced in Qingyuan City and 1-8 parts of Guangdong black clay produced in Huizhou City. Through adoption of the formula, the drying intensity can be improved, the drying difficulty of clay can be reduced, the bending strength and the performance of fired porcelain can be improved, the electromechanical failure load dispersity of the insulator can be reduced, and the running security of a grid can be improved.

Description

technical field [0001] The invention belongs to the technical field of electric porcelain, and in particular relates to a high-strength porcelain formula for manufacturing suspension porcelain insulators. Background technique [0002] With the development of the national economy, the construction of the power grid is also in full swing. As an important part of the power grid, transmission and transformation lines have higher and higher requirements for the quality and reliability of insulators. Therefore, it is urgent to study a reliable and high-strength porcelain insulator. Most of the existing insulator manufacturers still follow the principle of proximity, using a relatively high proportion of low-quality clay, adding some quartz sand, and not adding or adding a very small amount of low-quality bauxite to produce suspension porcelain insulators. The result is: after firing The performance of porcelain is poor, the strength of porcelain is generally low, and the dispers...
