Abstract

一种灭弧栅片，属于电力设备领域，其具有用于安装的安装部和用于接纳电弧的接纳部，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）。该方案的有益效果：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；3.只需在灭弧栅片上加工分流部（1）而无需增加其他灭弧零件即可实现开关的高效灭弧性能；4.分流部（1）可在灭弧栅片冲裁成型工艺中一起完成，几乎不增加成本；5.无需改变现有开关整体尺寸即可完成开关灭弧性能的升级。
