一、HRW3-10/100A概述    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。跌落式熔断器由*缘支架和熔丝管二部分组成，静触头安装在*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的酚醛纸管或环氧玻璃布管组成。拉负荷跌落式熔断器增强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，熔丝管借助熔丝张紧后形成闭合位置。当系统发生故障时，故障电流时熔丝*熔断，并形成电弧，消弧管受电弧灼热，分解出大量的气体，使馆内形成很高压力，并沿管道形成纵吹，电弧被*拉长而熄灭。熔丝熔断后，下部动触头失去张力二下翻，锁紧机械，释放熔丝管，熔丝管跌落，形成明显的开断位置。当需要拉负荷时，用*缘杆拉开动触头，此时主动、静动触头仍然接触，继续用*缘杆拉动触头，辅助触头也分离，在辅助触头之间产生电弧，电弧在灭罩狭缝中被拉长，同时灭弧罩产生气体，在电流过*时，将电弧熄灭。

二、HRW3-10/100A用途
    户外跌落式熔断器适用于35kv及以下电压频率50Hz电力系统中，作输电线路、电力变压器过载和短路保护，分合额定负荷电流只用，机械寿命≥2000次。

三、HRW3-10/100A使用条件
1.适用于环境温度上限40℃，下限-30℃之内。HRW3-10/200A
2.海拔不*过1000m，风速不大于35m/sHRW3-10/200A
3.熔断器不适用于下述场所HRW3-10/200A

3.2有剧烈震动或冲击的场所。HRW3-10/200A
3.3有异电化学气体作用及严重空气污秽，烟雾地区。HRW3-10/200A

四、HRW3-10/100A结构简介
    熔断器是由基座和消弧装置两大部分组成，灭弧管下端装有可能转动的弹簧支架，*使熔丝处于紧张状态，以*灭弧管在合闸位置的自锁，线路与变压器过载或短路中，熔丝熔断，熔丝*从灭弧管中抽出，灭弧管设计为逐级排气式解决在同一熔断器上开断大小电流的矛盾。HRW3-10/200A

英文翻译：
A, HRW3-10/100 A summary cascade, pull fuse load cascade fuse is high voltage outdoor protection electrical appliances. It device in the distribution transformer high pressure side or distribution lines on the way, used as a main transformer and line of short circuit, overload protection and points, and load current. Cascade fuse the insulating stents and investment fiber tube two parts, static contact head installed in insulation support both ends, move the contactor installed in molten fiber tube ends, melting away by the inner tube silk arc tube and the outer layer of the phenolic paper pipes or epoxy gl* cloth of tube. Pull load cascade fuse enhance the elasticity auxiliary contacts and arcing cover, for the points, the whole load current.
Cascade fuse in normal operation, melting molten silk fiber tube with a tight formed after the position. When a fault occurs, fault current were quickly fusing of silk, and formed the arc, away from the arc arc searing heat decomposition out large amounts of gas, the emb*y high formation pressure, and along the pipe form the blow, arc was quickly spin and go out. After the fusing of melt silk, the lower move contacts lose tension under two turn, lock machinery, release melt fiber tube, melting fiber tube fall, form apparent open circuit position. When need to pull load, the use of insulation lever open move contacts, this time the initiative, the static and dynamic contacts still contact, continue to use the insulation lever pull contacts, auxiliary contacts also separation, in auxiliary contacts between cells arc, arc in bangladesh.trapped in destroy cover is spun, at the same time, arcing mask produce gas, in the current over the zero hour, will arc put out.

Second, HRW3-10/100 A purpose
Outdoor cascade fuse is applicable to 35 kv voltage frequency frequency 50 Hz in power system, for tran*ission line, electric power transformer overload and short circuit protection, and rated load current only points, mechanical life quartile 2000 times.

Three, HRW3-10/100 A use conditions
1. Apply to 40 ℃ temperature environment ceiling, floor-30 ℃ within. HRW3-10/200 A
2. At no more than 1000 m, wind speed is not more than 35 m/sHRW3-10/200 A
3. Fuse shall not apply to places HRW3-10/200 A
3.1 have fuel or explosive dangerous places. HRW3-10/200 A
3.2 a violent vibration or impact of places. HRW3-10/200 A
3.3 has the different electrochemical gas function and serious air impurity, *oke area. HRW3-10/200 A

Four, HRW3-10/100 A structure profile
Fuse is by the base and arc device composed of two away, arcing tube with may turn of the spring bottom bracket, always make molten silk is in nervous condition, in order to ensure that the arcing tubes in the off position since the lock, the line and transformer overload or short circuit, melting silk fusing, melting quickly from arcing tube silk drawn, arcing pipe design for the exhaust t*e at the same level to solve the fuse open circuit size of the current conflict.
