一、HRW12-10/100A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、HRW12-10/100A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、HRW12-10/100A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、HRW12-10/100A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：
Spring, the sun shine, warm with world; Summer, the sun baking the biological and the sweat from the crowd asperses; Autumn, "huang2 die2" dance in the air, full of fruit also hanging in farmers joy of her mouth; Severe winter Snow White half empty, and ran cold face. In my impression, spring, summer, autumn is all good, and the winter cold can't help let I creation a tired of. This winter, the cold is the same as before, I have, however, to warm embrace, hug to the bright, more hug to joy...

Students in our eyes, winter is the most representative is the final exam. Each to this season, good students always p*ed the most tired day, for every penny good grades, to get parents reward teachers praise, for not live up to their parents expectations of the teacher, people are desperately trying, I am no exception.

That night, I write good homework, took the language book review up, each see key, I will be the first to cross down and read more than, let in one side of my mother to help me according to the content of the book to my back, just like that, back by one unit, the clock ticking, needle walk in recounting the p*age of time, once I see, has more than ten o 'clock, but I still full of spirit to carry the key, and I see you mother yawned, eyes was going to shut, my heart can't help produced no balance. I haven't recite, mother will put in: "good sleep, have been so late, trapped dead." In the mother take steps, suddenly I stood up, in the heart of the anger of a up, Shouting: "you think I'm not sleepy, don't want to go to bed? I do not just for the sake of testing a good result, make you happy spot, let me get this semester the pick-up, since I was better than point to? The teacher said the final exam is difficult, don't push on how line?" Mother doesn't say a word, just out of my room, I think there is so much more didn't review, and sit down, into a review of the state...

"Product dong" a knock on the door in my ears ring, tight with his mother came into the room, holding a cup of milk and apple, put down the left, I pull at eat up, suddenly feel particularly good, because I tasted a mother's love from the taste, mother's care. Again remind of the front of the mother did, in the heart is infinite regret and guilt, I walked into the mother bedroom, and saw his mother lying in bed was tossing and turning, keep the eyebrows, tears flow from my eyes, I'll hold up, say: "mother, I was wrong, I shouldn't you to lose your temper, in fact you are the most care about my study." "YingYing, I shouldn't complain about your work." We embraced tightly together, I hope time can freeze in this moment...

From then on, every night I serious review, and the mother of the company, and I more widely, every night the whole building is always my light the lamp of the late...

The final exam has painted a * end, scores also saw seen, though the results in the cl* of the "sixth row, but, I have satisfied, because, this is my efforts to eleven, to the ten days of the results; Although ending is not so good, but because the process to insist on and sweet!

Every day I persist and hard touched by yourself, like a fire in winter, warm my heart; I every night light bright symbol of books to me, like a little light in the darkness, the bright light your way. Right, more do not forget taste before joy, my mother every day and night support and accompanied, hope to get a good result and after reading good books deep eyes!

!!!!!I looked in the winter is good, warm, bright, joy is well covered the cold, that because of the winter of a fire, a little light in the darkness.
