分断电弧在固定触头中嵌入的磁体形成的径向磁场的作用下旋转。它们在DC42V电阻电路中产生。当触点闭合时，电路电流在5A到21A之间变化。用于旋转断开电弧的径向磁场的强度改变。电弧持续时间进行了研究。然后分析了分断电弧周期性旋转开始时的旋转频率、电弧长度和洛仑兹力，探讨了分断电弧旋转所需的条件。得到了以下结果。当断路电弧的旋转运动开始时的电弧长度L随着电路电流的增加而在恒定的磁通密度下几乎恒定。电弧长度L随着径向磁场的磁通密度的增加而减小。当弧长L达到由磁通密度决定的某一值时，断开电弧开始旋转运动。旋转频率和洛仑兹力随电路电流的增加而线性增加。
Break arcs are rotated with the radial magnetic field formed by a magnet embedded in the fixed contact. They are generated in a DC42V resistive circuit. The circuit current when the contacts are closed varies from 5A to 21A. The strength of a radial magnetic field for rotating break arcs changes. Arc duration is investigated. Then rotational frequency, arc length and Lorentz force when the periodic rotation of break arcs starts are analyzed to investigate the conditions required to rotate break arcs. The following results are obtained. The arc length L when the rotational motion of the break arc starts is almost constant at a constant magnetic flux density with an increase in circuit current. The arc length L decreases with an increase in the magnetic flux density of the radial magnetic field. The rotational motion of break arcs starts when the arc length L reaches a certain value determined by magnetic flux density. Rotational frequency and Lorentz force increase linearly with an increase in circuit current.
