| 摘 要： | 介绍了一种用于脉冲功率装置真空绝缘子的环氧树脂基复合材料的研制机理、制备过程和典型性能。初步测试结果表明，添加一定量的水合氧化铝颗粒可以使环氧树脂材料的表面电阻率由5×1016 Ω降低为6×1011 Ω，这一特性有利于释放由于沿面闪络等原因沉积在真空绝缘子表面的电荷，从而使材料在脉冲电压下的沿面闪络电压有所提高，实验得到在上升沿400 ns的脉冲电压作用下， 沿面闪络电压可从17 kV 提高到 28 kV。

| Abstract: | A new kind of epoxy compsite for vacuum insulator of the pulsed power devices is developed. The preparation process and the test result of the composite sample are presented in this paper. Some samples with different weight percentage are developed for the test. From the result, we can get that loading a quantity of hydrated alumina powder into the epoxy can decrease the surface resistivity from 5×1016 Ω to 6×1011 Ω. And using this method favors releasing the residual charge that deposited in the insulator surface during flashover. As a result, the flashover voltage of the epoxy composite is increased from 17 kV to 28 kV at same experiment condition. |
