高压真空熔断器

Gaoya dianqi, 1986
本文结合真空电弧的纵向磁场特性、分析了真空熔断器的燃弧特性和熄弧原理,从熔化特性出发分析其弧前过程,总结真空熔断器的优点,提出了一些具体的可能实现的产品方案。认为发展较高电压等级,大额定电流的真空熔断器,对提高目前高压熔断器产品的水平有积极作用,也是今后高压断器产品发展方向之一。

基于SSA-SVR和NSGA-Ⅲ的含铁心真空灭弧室纵磁触头优化设计

Gaoya dianqi
在高压真空断路器中，触头结构设计对磁场分布特性以及抑制电动斥力引发的对断路器运行的动态失稳具有关键作用。为此，本研究建立了杯状纵磁触头3D有限元模型，并通过融合支持向量回归(SVR)与麻雀搜索算法（SSA），以触头片开槽长度L1、宽度L2、径向旋转角度θ1、杯座厚度W、斜槽上下旋转角度θ2以及斜槽高度H六个关键结构参数作为输入，以电动斥力F、电流峰值时中心平面有效磁场占比S和过零时中心点磁滞时间t0分别为输出，构建了SSA-SVR高精度预测模型；最后通过NSGA-Ⅲ生成Pareto前沿 ...
