低压永磁真空开关
摘要
一种低压真空开关,它主要由低压真空开关泡和永磁操作机构组成,低压真空开关泡固定于开关基座上,动触头通过操作杆同基座相连接,永磁体与基座的吸合和分离通过一个线包的电流通断来控制,从而完成真空开关触头的合分。这种开关具有安全可靠、通流能力大、灭弧能力强、弹跳小、分合闸时间稳定、使用寿命长等突出优点。在供用电系统中使用该开关,可有效地提高开关和用电器的运行可靠性。

1.一种低压永磁真空开关,由真空开关泡和永磁操作系统构成,其特征在于:真空开关泡(1)的动触头(2)同操作杆(3)相连接,操作杆(3)连接一基座(4),基座(4)在线包(6)不通电流时吸合于永磁体(5)上,开关处于分闸状态,当线包(6)通电流时,基座(4)同永磁体(5)分离,动触头(2)向静触头运动,闭合开关,这时电流可在接线端子(7)和接线端子(8)之间流通,从而完成开关的合闸过程。
