Abstract

The invention provides a manufacturing method of a ceramic composite insulator with high electromechanical performance, and relates to the technical field of insulators. The manufacturing method of the ceramic composite insulator with the high electromechanical performance comprises the following steps: grinding an insulator core rod raw material to enable the particle size of each component to be 300-320 meshes, removing iron in the insulator core rod raw material, uniformly mixing the insulator core rod raw material with a cosolvent, a defoaming agent and an emulsifying agent, and squeezing mud to obtain a mixed mud cake; extruding the mixed mud cake in a vacuum pug mill to obtain a mud section, stably transferring the mud section to a shade drying area, keeping a gap between the height of the mud section and a hanging burning head, and keeping the mud section to have a certain shrinkage space, naturally drying in the shade for 4-5 days, and drying until the moisture is 1-2% to obtain a green body; by optimizing the particle level, improving the texture fineness and ensuring the quality stability, the product has the advantages of high mechanical strength, good electrical performance, no insulation aging, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of insulators, in particular to a method for manufacturing a ceramic composite insulator with high electromechanical performance. Background technique [0002] The ceramic composite insulator was removed after several years of operation for mechanical strength tests, and it was found that there were different degrees of mechanical strength decline. Some of the mandrels slipped under the rated mechanical load, and some mandrels came out of the end fittings. The reason for fracture: due to problems in the structure and process of the end connection, due to the creep characteristics of the mandrel and the aging of the material. During long-term operation, due to the combined effect of atmospheric environment, electric field, mechanical force, etc., the glass fiber in the mandrel will experience mechanical fatigue, the epoxy resin material will age, and the connection between the end fittings and the mandrel wil...
