纵磁式真空断路器的十年经验

Gaoya dianqi, 1988
一、前言 一些研究人员曾经证实:对真空电弧外施一个纵磁场,可以增进其断流容量,并阐明了稳定电弧的最佳磁场与电弧电流和触头间隙之间的关系。 作者所进行的研究,使纵磁场触头得以实用化,并制成了装有纵磁场触头的真空断路器。十年来,我们在研制高电压和大容量真空断路器的同时,利用这种纵磁触头生产了各种额定参数的真空断路器 ...

基于ELM与MOGWO的真空灭弧室结构优化设计

Gaoya dianqi
灭弧室作为真空断路器的核心，其电场分布与内部结构设计紧密相关。文中首先研究均压屏蔽罩、悬浮屏蔽罩结构、屏蔽罩与触头的间距以及触头形状变化对灭弧室电场分布的影响，发现场强在悬浮屏蔽罩端部、触头端部及悬浮屏蔽罩与触头之间的区域出现集中现象。为进一步改善灭弧室电场分布情况，文中提出了一种基于极限学习机（ELM）与灰狼算法（MOGWO）相结合的方法对灭弧室重要结构参数进行优化设计，建立了以悬浮屏蔽罩的斜坡上方长度L1、端部卷边半径R、卷边角度θ、屏蔽罩与触头表面距离L2和触头端部曲率半径r为输入，电场强度最大值、
