High-voltage electric porcelain plastic packaging process

Abstract

The invention provides a high-voltage electric porcelain cementing technique, which is formed by three parts, that is, cementing preparation, cementing and cementing maintenance and hardening. The cementing preparation process is characterized by carrying out cleaning processing on porcelain members and accessories, and applying a buffer protection coating onto each porcelain member and each accessory; the cementing process is characterized by carrying out preparation and use of cement adhesive, carrying out cementing positioning, and pouring the cement adhesive into the insulator porcelain members and the accessories to realize cementing; and the cementing maintenance and hardening process is characterized by carrying out early-stage maintenance and hardening treatment, and post-hardeningtreatment. The technique improves structure temperature stress state due to difference of thermal expansion coefficients among porcelain, metal and the cement adhesive, can relieve the impact of abnormal stress impact on an insulator, can enable the cement adhesive to have high fluidity, facilitates cementing of workers, improves efficiency and quality of the cementing work, meets requirement forhigh strength in cementing of a large-scale porcelain sleeve and reduces time in test, package and factory delivery after cementing of the porcelain sleeve.

Description

technical field [0001] The invention relates to the technical field of production technology of high-voltage power transmission products, in particular to a high-voltage electrical ceramic glue-fitting process. Background technique [0002] Adhesive binding is the most widely used assembly type of electric porcelain products at present. It mainly refers to: using the gelling or solidification characteristics of the adhesive, filling the gap reserved between the porcelain parts and the metal accessories through the adhesive, connecting and forming a mechanical assembly. The assembly and production technology of products with electrical and other characteristics that meet the requirements of use. [0003] The production process design and implementation of the glue binding of electric porcelain products and the management level and operation skills are directly related to the product quality, output, production cycle and economic benefits. The basic technological process of gl...

Problems solved by technology

[0003] The production process design and implementation of the glue binding of electric porcelain products and the management level and operation skills are directly related to the product quality, output, production cycle and economic benefits. The basic technological process of glue binding production is currently used in the glue binding process of electric porcelain products In the actual use process of cement adhesive, the fluidity of cement adhesive is poor, which is not conducive to the glue installation of workers, the maintenance cycle is long, and the maintenance process is too cumbersome, resulting in waste of energy, high cost, and the strength level cannot meet the requirements. Glued products are prone to cracks and breaks

The amount of cement used in traditional cement binders is very large, resulting in high cost of cement binders
