摘 要：澆注工藝是決定柱式絕緣子質量優劣的關鍵。通過真空澆注工藝制備了兩種1 100 kV GIS用柱式絕緣子，研究了模具結構對1 100 kV GIS用柱式絕緣子澆注成型過程的影響，提出臥式澆注模具結構，并分析了模具澆口位置、壁厚、排氣槽等因素對控制柱式絕緣子質量的重要性，對提高柱式絕緣子質量穩定性具有指導意義。
關鍵詞：環氧樹脂；1 100 kV GIS；柱式絕緣子；模具結構；質量穩定性

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
