摘　　要：为了驱动中高阻抗的高功率微波源,建造了油介质Blumlein型加速器Spark-05,其真空绝缘子界面为设计的难点之一。为了减小体积和结构简单,确定了真空界面采用径向绝缘结构,利用静电场有限元程序计算了界面上的电场分布,通过调整均压环和屏蔽环的形状使电场分布更加均匀,真空界面上沿面场强和三结合点处场强均得到了有效的控制,在1MV实验中工作稳定。Spark- 05 was built for conducting researches on medium/high impedance high power microwave sources. The interface between oil and vacuum was one of the keys to the system design. For reasons of compactness and simplicity, a disk type vacuum insulator was adapted. Electrostatic field along the insulator surface was calculated. By adjusting the position of the shielding rings, electric fields were well distributed, and the fieM around the triple junction was controlled. The insulator worked well in 1MV experiments afterwards.
