1、用途
1, the use,

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，它装配在配电变压器高压侧或配电线支干线路上，作输电线路、电力变压器过载和短路保护及分合额定负荷电流之用。
Cascade fuse and pull load cascade fuse is high voltage outdoor protection electric appliance, it assembly in distribution transformer high pressure side or distribution lines on a main, transmission line, electric power transformer overload and short circuit protection and points and the use of load current rating.

2、结构简介
2, the introduction to the structure

跌落式熔断器由绝缘支架和熔丝管两大部分组成，静触头安装在绝缘支架的两端，动触头安装在熔丝管的两端，熔丝管由内层的消弧管和外层环氧玻璃管组成。
Cascade fuse the insulating stents and investment fiber tube two major components, static contact head installed in insulation at both ends of the stent, move the contactor installed in melting at both ends of the fiber tube, melting away by the inner tube silk arc tube and outer layer of epoxy glass tube.

拉负荷跌落式熔断器增加弹性辅助头及灭弧罩，用以分、合负荷电流。
Pull load cascade fuse increase elasticity auxiliary head and arcing cover to points, and load current.

跌落式熔断器在正常运行时，熔丝管借助熔丝张紧后形成闭合位置。
Cascade fuse in normal operation, melting molten silk fiber tube with a tight formed after the position.

当系统发生故障时，故障电流使熔丝迅速熔断，并形成电弧，消弧管受电弧灼热，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。
When a fault occurs, the fault current melt quickly to fuse silk, and formed the arc, away from the arc arc searing heat decomposition out large amounts of gas, make the tube forming high pressure, and along the pipe form the blow, arc was quickly spin and go out.

熔丝熔断后，下部动触头失去张力而下翻，锁紧机构释放熔丝管，熔丝管跌落，形成明显的开断位置。
After the fusing of melt silk, the lower move contacts lost under tension over, locking mechanisms release melt fiber tube, melting fiber tube fall, form apparent open circuit position.

当需要要拉负荷时，用绝缘杆拉开动触头，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，电弧在灭弧罩狭缝中被拉长，同时灭弧罩产生气体，在电流过零时，将电弧熄灭。
When need to pull load, the use of insulation lever open move contacts, this time the initiative, the static help contacts still contact, continue to use the insulation lever pull contacts, auxiliary contacts also separation, in auxiliary contacts between cells arc, arc in the arcing cover slit by spin, at the same time, arcing mask produce gas, in the current over the zero hour, will arc put out.
