摘　　要：随着新能源技术的发展,开关电器正向高技术参数、高电压等级、大容量方向发展。真空灭弧室作为真空开关的核心,其绝缘设计分析至关重要。采用蒙特卡罗方法模拟金属蒸气和带电粒子在真空灭弧室内分布,采用电场影响域方法对含金属蒸气和带电粒子的真空灭弧室本体构建复杂网络拓扑模型,计算分析网络统计特征,找到绝缘薄弱关键点。The time-dependent distributions of metal vapor uum interrupter （ VI）, were mathematically described with the and charged particles, emerging in the 4.5 kV vac- complex network topology mode/ based on electric field influence domain, theoretically analyzed in electrodynamics and numerically simulated in Monte Carlo method the key weak insulation spots. The statistical characteristics of the complex network with the different opening widths, including the average path-length, clustering coefficient and degree distribution, were calculated. The simulated results show that the complex network possesses the features of a typical small-world network. For example, the small average path-length reveals that a weak electric-field fluctuation results in a strong glow discharge ; the degree distribution is consistent with the VI＇ s insulation configuration, because break-down of- ten occurs at the node,where degree-distribution is high inside VI＇s shield cover
