一、RW4-10/100A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。RW4-10/200A
    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。RW4-10/200A

二、RW4-10/100A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、RW4-10/100A使用条件RW4-10/200A
1.适用于环境温度上限40℃，下限-30℃之内。RW4-10/200A
2.海拔不*过1000m，风速不大于35m/sRW4-10/200A
3.熔断器不适用于下述场所RW4-10/200A
3.1有燃料或*危险的场所。RW4-10/200A
3.2有剧烈震动或冲击的场所。RW4-10/200A
3.3有异电化学气体作用及严重空气污秽，烟雾地区。RW4-10/200A

四、RW4-10/100A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。RW4-10/200A

英文翻译：

In the growth of the road, I had many memorable things, there are also many to comprehend. Among them, make me the most unforgettable is the sixth grade and junior high school of learning and life. In these two periods, have knowledge, have to explore. A curious, have imagination, have the joy, also have trouble. Summary, it is both good and bad.

Sweet. Six grade school semester, I will feel a winter holiday efforts were not in vain. Take mathematics, whole winter vacation I attack aoshu, therefore, I at the commencement of mathematics result in the cl* has is far ahead and almost every time tests are full marks, and xinghua middle school in final exam, won the first prize. I taste blood, but also not some pride.

Bitter. The sixth grade next semester, I spent in almost all the sweet. Until one test scores down, I pledge to be a great knock up. A test that day, I walked into the examination room with confidence, in the mind to think, xinghua exam I succeeded, one should also isn't. Papers hair down, I took a look at roughly, well, simple, I how long it was finished examination papers, proudly sitting, end also didn't see until the exam at examination paper. Later and others a pair of the answer, just discover oneself a mathematical problems wrong. I can't help but regret extremely. Finally, I MingLaSunShan in nine points. Unexpectedly, six years of hard work was a bitter pill for.

Acid. When the bell rang, the graduation ceremony ended, primary school life forever said goodbye, study together and life for six years of cl*mate, also the broke up. I blankly out of the cl*room, something to feel so heart. How? And I always * how to also feel fuzzy eyes, nose, the sour?

Spicy. Finally, I still get it in a walk to the campus, in here to study and life. Every day, the teacher the *ignment is much more, and primary school life than up, junior middle school life is too hot. But it is the hot, just make splendid life.

Frustrations is each person must grow in the way of the experience. Only through sour, bitter, hot three sections of road, the road ahead will be flat, will be light, the rest of the life to all plain sailing.
