N2 - The intrinsic defects (μm ∼mm) at the metal-insulating material interface such as inevitable metal tip, may cause electric field distortion and partial discharge under electrical stress, which has become the main cause of insulation failure of power equipment. In this paper, an atmospheric pressure micro-plasmajet (μ-APPJ) with hexamethyl disiloxane (HMDSO) was used to treat the tip defects at the interface between copper metal and epoxy resin (Cu-EP), and the electrical properties of the Cu-EP interface were studied by flashover voltage and partial discharge. The results show that the intensity of the main spectral lines of the emission spectrum decreases first and then remains stable with the increase of HMDSO addition, and it reaches the best effect at 5 mL/min. The direct treatment of Cu-EP interface defects can significantly enhance the discharge intensity of μ-APPJ and improve the decomposition efficiency of HMDSO. After μ-APPJ treatment, the electrical properties of the Cu-EP interface are significantly improved, the PD initial voltage increased by 44.4%, and the average discharge charge decreased by 68.7%. In addition, the breakdown strength was also increased by 38% (from 6. 7S to 9.36 kV) after μ-APPJ treatment.
