纵磁场触头设计要点分析

An Analysis of Designing Points about the Contactor in Relation to the Longitudinal Magnetic Field

从建立纵磁场触头的数学模型出发，分析了真空开关纵磁场触头线圈及触头面上引弧区的设计规律。

Starting from an establishment of a mathematical model on the contactor in relation to the longitudinal magnetic field, the paper analyzes the regulation and law for designing the area introducing electric arc to result from the surface of the contactor and its contacting coils in the longitudinal magnetic field of a vacuum switch.
