Gaoya dianqi直流组合电器可以将短路故障电流由真空横磁转移开关转移至并联断路器或熔断器上完成开断，在直流配电网中具有应用潜力。为了得到适用于直流组合电器的真空开关触头设计，文中研究了外施横向磁场下真空电弧在卍字型横向磁场触头上稳定阶段的弧隙中磁场分布和电弧受力规律。基于有限元仿真方法，结果显示卍字型横磁触头与外施磁场叠加后将改变电弧附近磁场分布特性，当电弧处于卍字型触头上的某些位置时，其受力特性不利于电弧快速向触头边缘运动。而电弧在越过卍字型触头开槽时受力变化可能使电弧运动偏转，延长电弧的稳定阶段时间 ...

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 ...
