Abstract

In order to study the performance of the modified epoxy resin in the operating environment, the epoxy resin samples after surface modification treatment, including ozone oxidation treatment and electron beam irradiation treatment, were subjected to electric-heat-gas combined aging experiments. The surface flashover voltage was measured regularly, and the infrared spectrum and surface trap characteristics of the aged samples were compared. The surface flashover voltages of three kinds of samples show a downward trend with aging time. The samples which have been surface modified still have better performance in surface flashover voltage than that have not been modified. The sample oxidized by ozone has the highest surface flashover voltage both aged and unaged.
