Lastly, by means of a mass of experiments on the vacuum interrupter arrangements with single break or triple breaks in series, the breakdown voltage improvement factor, breakdown statistical property and electric distribution in breaks are researched.

• 因此；应该通过设计最大限度地提高多断口真空开关各断口的电压分布均匀性；从而提高其击穿电压增益倍数；最大限度地发挥多断口真空开关的优势。 本研究还设计和制作了40.；5kV电压等级的光控模块式真空开关单元样机；进行了样机的动作精度实验。
