| 摘 要： | 研究了由外部接线产生的磁场对真空电弧的影响.这一横向磁场会将电弧吹向弧隙外侧,削弱了真空灭弧室的开断能力.因而提出了一种磁屏蔽罩,以避免真空电弧受到外部磁场的影响.试验结果表明,该磁屏蔽罩可有效地提高真空灭弧室的开断性能.

| Abstract: | The influence of the magnetic field generated by external circuit on the vacuum arc is studied. Such horizontal magnetic field will make the arc move out of the electrode gap,and reduce the interrupting ability of the vacuum interrupters. A kind of magnetic shield case,which can prevent the arc from being affected by the external magnetic field,is developed in this paper. The experimental results show this magnetic shield case can improve the interrupting performance effectively. |
