一、RW7-10/100A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、RW7-10/100A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。RW7-10/200A

三、RW7-10/100A使用条件
1.适用于环境温度上限40℃，下限-30℃之内。RW7-10/200A
2.海拔不*过1000m，风速不大于35m/sRW7-10/200A
3.熔断器不适用于下述场所RW7-10/200A
3.1有燃料或*危险的场所。RW7-10/200A
3.2有剧烈震动或冲击的场所。RW7-10/200A
3.3有异电化学气体作用及严重空气污秽，烟雾地区。RW7-10/200A

四、RW7-10/100A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：
I miss the time before, and I want to her to her care, love and care.

I am a very unfortunate girl, and my mother is a year in my working out again, I hope to bring up my grandma, in my memory is no mother, mother had kissed me, I want to get her kiss, I think mom's kiss is warm, sweet and happy is full of love.

Mom, go out to about six years, I just in a grade to become a young pioneers, my mother came back, I really and excited, and excited. Mother was crying, and she said: daughter mother good miss you, see you mom really happy. You know my father and I in guangzhou will want to, our daughter wants to grow taller yao in long, beautiful? Mother arms in and touched my head, drop by drop tears of play on my head. Mother kissed me on my forehead, I very happy.

But I in this happy for the mother * left me, mom is in the return of the third Monday to leave me, the day's night mom closely to hug me, with her mouth kiss really my forehead, at that time I really happy, mother holding the me sleep, when I woke up and my mother left me. I'm sorry to be nasty, several days didn't have a meal just to tightly compressed into a ball, two eyes dull looking at framed photos, in the mouth by talking, mother you mother good or bad, why did you take my own throw down, I miss you so much, in my memory we only got along for three weeks, I haven't enjoy the warmth of a mother's love is you leave me, I really miss you, want you to give me another kiss, want to let you to hug me, and want to let you......

Mom, I don't want to, I'll be your daughter did not get you the third a kiss, mom, you kiss my that moment. Let me just feel the warmth of the world to this, mom, I no longer afraid of other children discrimination I had no parents, mom, and your last kiss but let I lost you, mother in my memory you kiss me only twice, the first time you come back in when you kiss, the second a kiss is in you completely leave I kiss, mother you is to want to let you be my permanent memory kiss?

Finally a kiss, always kiss, * banished, * disappear.
