摘　　要：通过对国内外绝缘油技术标准的概述,指出高压互感器用绝缘油的技术要求。针对目前国内常用的5种高压互感器绝缘油,在使用性能上进行对比分析。结果表明:1#、2#绝缘油是负析气性绝缘油,适用于高压互感器;3#、4#、5#绝缘油是正析气性绝缘油,不适用于高压互感器;在芳烃含量、抗析气性能、产气性能、油泥溶解性能和氧化安定性的平衡上,1#绝缘油的综合性能最好,析气性最低,氧化安定性最好。The technical standards of insulating oil at home and abroad were summarized and the technical requirements of insulating oil for high voltage instrument transformer were pointed out.The using properties of five kinds of insulating oils commonly used in high voltage instrument transformer in China were compared and analyzed.The results show that No.1 and No.2 insulating oils are negative gassing insulating oil,which are suitable for high voltage instrument transformers.No.3,No.4,and No.5 insulating oils are positive gassing insulating oil,which are not suitable for high voltage instrument transformers.On the balance of aromatics content,gassing properties,gas production properties,sludge solubility,and oxidation stability,No.1 insulating oil has the best comprehensive performance,the lowest gassing,and the best oxidation stability.
