摘　　要：变压器油中溶解气体可由高分子膜自动分离,不同分子膜对不同气体的渗透性能差异很大。研究几种高分子膜的透气、机械与耐热性能的结果表明,微孔聚四氟乙烯膜各种性能优良,且已运行4年,尼龙管柬透气性最好但国内应用刚刚起步。The dissolved gases in the transformer oil can be separated automatically with high polymer membranes. However, the permeability of different membranes are quite different for different gases. This article discusses the permeability, high temperature endurance, mechanical stability and characteristics that are suitable for online chro-matograpgy of the transformer incipient faults of high polymer membranes.
