摘要(Abstract)：

为向基于光控模块的多断口真空断路器的静态、动态绝缘特性设计提供参考,建立三维有限元分析模型,计算126 kV U型布置的三断口真空断路器的静态电位分布和真空灭弧室内部的电场分布。利用110 kV振荡型合成试验回路,进行低电压、小电流三断口串联断路器样机的开断试验,测量三断口的瞬态恢复电压分布。计算和试验结果表明:三断口真空断路器的静态和动态电压分布不均匀,高压端断口的静态分压超过65%,串联样机进行试验时底部可以不安装支架;高压端断口的动态分压(瞬态恢复电压峰值)超过60%,1 000 pF均压电容可以满足低电压、小电流开断均压要求,高电压、大电流开断情况需进一步验证。
