Preparation method of high-strength aluminum oxide suspension insulator and porcelain insulator structure
The invention discloses a preparation method of a high-strength aluminum oxide suspension insulator and a porcelain insulator structure, wherein the preparation method comprises the following steps: 1, adopting the following blank raw materials in percentage by mass: 20-30% of industrial aluminum oxide, 15-25% of feldspar, 20-25% of ball clay, 20-25% of clay granules with the granularity of 20-40 meshes and 3-5% of SrCO3; 2, sanding the blank raw material to obtain blank particles with the diameter of 3-5 microns; 3, sequentially carrying out ball milling, impurity removal, moisture control, drying, fettling, drying, glazing and sintering on the blank particles obtained in the step 2 to obtain an aluminum oxide porcelain insulator body; 4, processing the aluminum oxide porcelain insulator body into the shape that the outer contour of the longitudinal section is in a rounded rectangle shape and the inner contour is of an arch-shaped structure; and assembling the porcelain head with a steel foot to obtain a porcelain insulator structure. The prepared porcelain insulator has the advantages of high production qualification rate, stable mechanical performance, stable electrical performance and the like, and meets the requirement of safe operation of a high-voltage line.
本发明公开了一种高强度氧化铝悬式绝缘子的制备方法及瓷绝缘子结构，包括以下步骤：步骤1：采用如下质量百分比的坯料原料，包括工业氧化铝20～30％、长石15～25％、球土20～25％、黏土粒料20～25％和SrCO33‑5％，其中，黏土粒料的颗粒度在20‑40目；步骤2：对坯料原料进行砂磨，得到直径为3‑5微米的坯料颗粒；步骤3：对步骤2得到的坯料颗粒依次进行球磨、除杂、水分控制、干燥、修坯、烘干、上釉、烧结得到氧化铝瓷绝缘子本体；步骤4：将氧化铝瓷绝缘子本体制作为纵截面外轮廓呈圆角矩形状且内轮廓呈拱门状结构，作为瓷头，将该瓷头与钢脚进行组装，得到瓷绝缘子结构；制备得到的瓷绝缘子具有生产合格率高、机械性能稳定、电气性能稳定等优点，满足高压线路安全运行要求。
