一、HRW11-10/100A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、HRW11-10/100A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。HRW11-10/200A

三、HRW11-10/100A使用条件
1.适用于环境温度上限40℃，下限-30℃之内。HRW11-10/200A
2.海拔不*过1000m，风速不大于35m/sHRW11-10/200A
3.熔断器不适用于下述场所HRW11-10/200A
3.1有燃料或*危险的场所。HRW11-10/200A
3.2有剧烈震动或冲击的场所。HRW11-10/200A
3.3有异电化学气体作用及严重空气污秽，烟雾地区。HRW11-10/200A

四、HRW11-10/100A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。

英文翻译：

Winter, snowflakes are flying in the sky, fall on the ground, the tree room, there is all the snow scene.

I'm looking out of the window lookout out only a little girl, in practiced with the the snow. Oh, I know her, she is our unit is the *allest of the girl. Remember she just moved here, or summer, a pair of black eyes nervous looking at this strange new environment, tightly took the mother's hand, as if afraid oneself a didn't notice, mother disappeared like. That afternoon, when I met her again, she is doing their own *all handkerchief, I from her side after, she sees with big eyes, ask me: "sister, you have a handkerchief?" I shook my head, and I thought: how old, still use a handkerchief! She didn't see my heart like the emotional changes, the eyes revealed innocent *ile.

"That I send you a right, le le has a lot of, what color of article, what do you like yan..."

She didn't say that finish, I busy said: "no, thank you." Said, will leave, the pair of big eyes and lele, is full of disappointment.

Send not to send me a handkerchief, there really is so important...

A voice, broke my thoughts, I put on the heavy clothing, and went downstairs.

"Big sister."

Is this familiar voice, I have some impatient and turned away, and she saw I ignore her, then say: "do you know this word?" I glanced at: "xiang."

"Xiang." She repeated.

Looking at her to write in the snow, curiosity arises spontaneously.

"What are you doing?"

"Write ah, the teacher told us to review the holiday, otherwise, o the forgot."

"That why in the cold outside? The house more warm write!!!!! Do you see your hands are frozen, let's go home, is nobody home?"

"Sister, my house someone, you don't have to worry about me. Because I always work have no perseverance in writing to review, can exercise outside my own."

Such words, deeply moved me, I thought suddenly his vacation stuff to play, do not say first put parents, teachers are lost to the teaching of the brain, even my own plans are not finished. So the little children to review, I don't also it's back to learn? A lower the head, he wrote to lele crooked word: good good study, day day up.

I not from get turned around to go home, behind the young voice sounded.

"Big sister goodbye!"

I turn head and see a ray of sunshine is rested on her body, just like an angel beautiful.

"Goodbye."
