一、HRW5-35/100A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。HRW5-35/100A
    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。HRW5-35/100A

二、HRW5-35/100A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。HRW5-35/100A

三、HRW5-35/100A使用条件
1.适用于环境温度上限40℃，下限-30℃之内。HRW5-35/100A
2.海拔不*过1000m，风速不大于35m/sHRW5-35/100A
3.熔断器不适用于下述场所
3.1有燃料或*危险的场所。HRW5-35/100A
3.2有剧烈震动或冲击的场所。HRW5-35/100A
3.3有异电化学气体作用及严重空气污秽，烟雾地区。HRW5-35/100A

四、HRW5-35/100A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：
a

When I was a child, mother is a sunshine, is the sea, and father in my mind is a high mountain, but tall and profound, appear very mysterious. I want to close to him, he that mysterious veil uncover, however I fear, afraid to come near him, he conquered. I for this "mountain" helpless, I can only in "mountain" feet wandering, occasionally timidly look up, but also fear that a harsh glare met, a cold face, without a *ile on his face, as if born without laughing cells. So I feel the love of the father, and the father in my heart is strange a high mountain.

two

As the growth of the age, I began to feel father actually very love me, care for me every step of the way, I learned to ride a bicycle growth, hand on my father is, and let go of is also father, look on coldly sea is the father. I after the fall, and ran over is the mother, the mother gently tap out my body of the earth, fear my hand cut, feet were to fall. Father helped the bicycle, let me once again, after a few times after the fall, I finally learned to ride a bicycle. The whole process, father just *ile, no comfort and praise.

That is my father and I first go alone buy eggs, my father and I were the hand carrying a basket of eggs, walk in a corner, opposite a a cycling soon of boys, fiercely up our hands knocked it out of eggs, two kilograms of eggs almost all broken. I thought his father will blame him, and let the boy father only later must be careful, a little blame mean also have no. I head full of puzzled and asked father, father's answer is just a very simple words: "if you are the cl*mate, others scold you, your heart this how sorry!" So a word is the father, that I was lost in thought. This sentence is so simple, but expressed father forgiveness, love.

three

Everyone said that there is only a mother good, and I said there is only dad. Father a gentle, though a *all and exquisite, but he is a brave man. Man should strive constantly for self-improvement, this is man spirit, is the only way is the real man, therefore, the world just appear the stern father. The stern father love is silent, love is silent. When we are silent father grew up under a little bit, we must not ignore the song as pure and honest, high mountain of a father.

Comment on: *all the author are good at finding love, feel the love. The father loves the observation of *all, the description is so exquisite, and can use many kinds of techniques to express father, let the reader feel for the father loves the significance. The article end to echo, primary and secondary arrangement is proper, the deficiency is expression way some single, narrative content are many, the description and so on expression didn't give full play to its function.
