摘　　要：长短对低压开关电器的开断性能和限流性能有很大的影响，而电弧停滞时间本身受触头区域的磁场、触头开断速度、触头材料、灭弧室结构与器壁材料、触头形状和表面情况等因素的影响。The arc stagnation is an important phenomen at the open - break process of low voltage switch electric appliance. The time of arc stagnation severely imfluences the open - break performance and limited current characteristic. However, the time of arc stagnation is affected by the factors of magnetic field of contact part, open - break speed of contact part, contact part material, structure of arc chamber and material of device wall, shape and surface of contact part, and so on.

关 键 词：低压电器 电弧停滞现象 电弧停滞时间 电寿命 磁感应强度
