摘　　要：油中溶解气体分析是变压器状态检测最为常见且可靠的方法,油气分离技术则是溶解气体分析中重要的一环。在油气分离技术中,渗透膜是一种较为新颖且颇具前途的分离技术。相较于传统的油气分离方法,渗透膜技术具有结构简单、体积较小、免于维护等优点,因此该方法是油中溶解气体分析研究的热点之一。该文首先对近年来应用于油气分离的高分子渗透膜材料及其结构进行了综述;然后,结合现有研究对几种常见的不同类型的高分子渗透膜进行归纳、总结和对比;最后,在总结当前研究的基础上,提出并讨论高分子渗透膜在变压器油中溶解气体分析领域中未来的发展方向。Dissolved gas analysis(DGA)is the most approved method for transformer insulation state detection.Meanwhile,oil-gas separation technique plays a significant part in DGA.For oil-gas separation,membrane technique is considered as a novel and promising method.Compared with conventional methods,membrane technique possesses several merits,such as simple structure,small size and maintain-free.Therefore,it has become the focus in DGA field.A review of recent researches about polymers membranes applied in DGA was provided in this paper,which included research status of both the material and the structure of polymers membranes.Then,the characteristics of several typical polymers membranes were summarized for comparison.Lasty,based on current research results,the development trends of polymers membranes for DGA were proposed.
