(1)闸刀开关的作用
闸刀开关是一种手动配电电器。主要用来隔离电源或手动接通与断开交直流电路,也可用于不频繁的接通与分断额定电流以下的负载,如小型电动机、电炉等。
闸刀刀开关是经济但技术指标偏低的一种刀开关。闸刀开关也称开启式负荷开关。
(2)外型与结构
图 是它的外形与结构图,它主要有:与操作瓷柄相连的动触刀、静触头刀座、熔丝、进线及出线接线座,这些导电部分都固定在瓷底板上,且用胶盖盖着。所以当闸刀合上时,操作人员不会触及带电部分。胶盖还具有下列保护作用:(1)将各极隔开,防止因极间飞弧导致电源短路;(2)防止电弧飞出盖外,灼伤操作人员;(3)防止金属零件掉落在闸刀上形成极间短路。熔丝的装设,又提供了短路保护功能。
