Abstract

一种电动隔离开关，属于电力设备领域，其包括电动操作机构（8）和触头室（9），触头室（9）设置有动触头（15）、静触头（16）、接线端子、灭弧室及传动机构（14），灭弧装置具有多个灭弧栅片（4、5、6）和用于安装灭弧栅片（4、5、6）的绝缘支撑件，灭弧栅片（4、5、6）具有安装部和接纳部，接纳部设置有用于分割电弧的分流部（1），分流部（1）包括贯穿接纳部的通孔（3）和凸出接纳部的斜舌（2），斜舌（2）设置在通孔（3）远离电弧入口端的一侧且朝电弧入口端延伸，斜舌（2）与接纳部表面的夹角为锐角，斜舌（2）的根部与接纳部连续，接纳部沿电弧的传播方向设置一个或者多个分流部（1）。有益效果是：1.相同的空间内一束长弧被分割出更多的短弧；2.弧隙电压锐减，大大地降低了弧隙电弧重燃的机会。
