综述了目前国内外绝缘材料沿面闪络的研究现状,介绍了沿面闪络试验研究采用的典型电极结构和测量方法,沿面闪络传播途径、发光强度等特性变化,以及不同外界条件对沿面闪络发展特性的影响,提出了绝缘材料表面沿面闪络试验及理论研究需要深化和拓展的方向,为改善设备的绝缘和改进线路设计提供理论依据。

The research status of surface flashover of insulating materials at home and abroad was reviewed. The typical electrode structures and measuring methods used in surface flashover test, the varia-tion of propagation path and light intensity of surface flashover, and the effect of different external conditions on the surface flashover development were introduced. The further study directions of surface flashover experiments and theoretical research were put forward, which could provide a new theory evidence for improving the equipment insulation and the design of transmission line.
