摘 要:浇注工艺是决定柱式绝缘子质量优劣的关键。通过真空浇注工艺制备了两种1 100 kV GIS用柱式绝缘子,研究了模具结构对1 100 kV GIS用柱式绝缘子浇注成型过程的影响,提出卧式浇注模具结构,并分析了模具浇口位置、壁厚、排气槽等因素对控制柱式绝缘子质量的重要性,对提高柱式绝缘子质量稳定性具有指导意义。

Abstract: The casting process is the key to determine the quality of the column insulator. Two types of 1 100 kV GIS column insulators were prepared by vacuum casting. The influence of the mold structure on the casting process of 1 100 kV GIS column insulators was studied. The horizontal casting mold structure was proposed, and the location of the mold gate factors such as wall thickness, exhaust grooves, etc. are important for controlling the quality of column insulators and have guiding significance for improving the quality stability of column insulators.
Key words: epoxy resin; 1 100 kV GIS; post insulator; mold structure; quality stability
