一、RW12-10/100A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、RW12-10/100A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、RW12-10/100A使用条件
1.适用于环境温度上限40℃，下限-30℃之内。
2.海拔不*过1000m，风速不大于35m/s
3.熔断器不适用于下述场所
3.1有燃料或*危险的场所。
3.2有剧烈震动或冲击的场所。
3.3有异电化学气体作用及严重空气污秽，烟雾地区。

四、RW12-10/100A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：
Today is everybody in anticipation of the fifteenth day the Lantern Festival. Everybody is in the table eating sweet dumpling, looking at a wonderful TV program?

Our hometown, the Lantern Festival every year to the fireworks, watching lanterns again, this year will be no exception. In the evening, my mother and father came to see the street lamp. See the sea of people on the road, the whole road into "sidewalk", look to see at the end of the stream.

The center of the city groups more lively, more beautiful lanterns! Here wide variety of lanterns make the person dazzling, too many things to see. Look at the beautiful rabbit lamp, pink body, long ears, *all, round faces a pair of sweet *ile, swinging arm, as if in with everyone said: "I wish you a happy Lantern Festival!" Look at the peach lamp, pink impression, yan man with some red peach, peach bottom has the big green leaves, which was both beautiful and simple. And the GongYanYan "star", will be to move "chicken".............

In the Mid-Autumn festival very much, we suddenly found in east road there are many people, so, I and my parents walked over and looked at. Oh! It is lantern riddle quiz! The write "a pair of long ears, eyes red and red, don't eat meat and fish, eating vegetables and turnip" play a animals. I think: mystery must be "rabbit", because this year is rabbit years! Sure enough, I guessed right!

Watching lanterns again, we came to watch the fireworks longshan square. See the dark blue sky was full of multicolored fireworks, open fireworks as a pompoms, like pieces of snowflakes, like million dragged the ribbon meteor, the dark night sky as the day as the same, the night of the lantern be very beautiful, I can be over.

Million colorful fireworks soared into the sky, fireworks exploded after, pieces of paper flower falls, even some paper flowers with stood glittering thing, it was really like the meteor sallow color; Some fireworks exploded later is a double, then become animal shape; Some dynamite later as from under the meteor shower, brush brush to to fall; And as a series of colorful rings of gold, and put the sky became brilliant! It's beautiful extremely! Really some "most expensive three thousand feet, doubt is the galaxy fell nine days" flavor.

The moon was west to fall, I would have to leave. But view lamp or a steady stream of, all kinds of colored lights like the heaven of the stars, sparkles. Is really "night drunk, only reason the awaken of spring lanterns strong". I believe that, with the increasingly developed country, the Lantern Festival in the future will be better, more make people look forward to!
