电力设备在雨雪等特殊环境下,设备表面及其连接处往往会因吸收水分而影响绝缘性能造成线路事故。应用聚合物绝缘防水材料涂敷在设备表面,可降低水分对电力设备绝缘性能的影响,从而保障设备的安全运行。综述了目前聚合物基防水材料的研究现状,讨论了材料种类、结构及性能差异,并提出了针对电力设备防水绝缘需求聚合物基防水材料应具备的结构特点及功能,以期为该类材料在电力设备运行维护领域的研发与应用提供依据。
In the special environment with rain and snow,the electric equipment surface and its connections were covered by the water,resulting in the insulation failure and the destruction of the power system.To maintain the grid security,the polymer insulating waterproof materials were coated on the surface to prevent the influence of water on the insulate properties of the equipment.Here the progress of polymer-based waterproof materials was summarized,and discussed the relationship of the property,structure and kinds of the materials.The molecular structures and functional properties of the materials were proposed for their development and application in the area of waterproof insulation of electrical equipment.
