摘 要：澆注工藝是決定柱式絕緣子質(zhì)量優(yōu)劣的關(guān)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(jié)構(gòu)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(jié)構(gòu)，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(zhì)量的重要性，對提高柱式絕緣子質(zhì)量穩(wěn)定性具有指導(dǎo)意義。
關(guān)鍵詞：環(huán)氧樹脂；1 100 kV GIS；柱式絕緣子；模具結(jié)構(gòu)；質(zhì)量穩(wěn)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
