跌落式熔断器及拉负荷跌落式熔断器是户外高压保护电器。它装置在配电变压器高压侧或配电线支干线路上，用作变压器和线路的短路，过载保护及分，合负荷电流。跌路式熔断器由绝缘支架和熔丝管二部分组成，静触头安装在绝缘支架两端，动触头安装在熔丝管两端，熔丝管由内层的消弧管和外层环氧玻璃管组成。拉负荷跌落式熔断器增加弹性辅助触头及灭弧罩，用以分，合负荷电流。跌落式熔断器在正常运行时，熔线管借助熔丝张紧后形成闭合位置。当系统发生故障时，故障电流使熔丝迅速熔断，并形成电弧，消弧管受电弧炽热，分解出大量的气体，使管内形成很高压力，并沿管道形成纵吹，电弧被迅速拉长而熄灭。熔断丝断后，下部动触头失去张力而下翻，锁紧机构释放熔断丝，熔断丝跌落，形成明显的开断位置，当需要拉负荷时，用绝缘杆开动触头，此时主动，静助触头仍然接触，继续用绝缘杆拉动触头，辅助触头也分离，在辅助触头之间产生电弧，电弧在灭弧罩峡缝中被拉长，同时灭弧罩产生气体，在电流过领时，将电流熄灭。
