一、HRW7-10/100A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。HRW7-10/200A

二、HRW7-10/100A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。HRW7-10/200A

三、HRW7-10/100A使用条件
1.适用于环境温度上限40℃，下限-30℃之内。HRW7-10/200A
2.海拔不*过1000m，风速不大于35m/sHRW7-10/200A
3.熔断器不适用于下述场所
3.1有燃料或*危险的场所。HRW7-10/200A
3.2有剧烈震动或冲击的场所。HRW7-10/200A
3.3有异电化学气体作用及严重空气污秽，烟雾地区。HRW7-10/200A

四、HRW7-10/100A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。

The Christmas tree covered with silver on the off and the wearing a red dress with Chinese lasting appeal, a look and then know, years.

From the twelfth 23 start, we put the arrival of the year in order to plan and planning, families are busy to purchase special purchases, cleaning, buy couplets. A into bazaar, see all kinds of lanterns, couplet emerge eyes, commodities have been on sale promotion, the wide variety of, overwhelming.

The thirty, also is the New Year's eve and New Year's day is the most of a busy day. Parents get up early and went to the market to buy fresh seafood, a home, busy up. The parents busy all kinds of dishes are ready, before I'm so looking forward to the New Year, but with the city NianWei more and more light, somehow, now I just don't have the expectation. Nearly nightfall, every family the lights lit up, the *ell of food *all fishes the float, fragrance tempting glove, however the scent of a thick reunion breath. Finished the reunion dinner, the Spring Festival evening began, the family immersed in endless joy, laughter.

The lunar year, first 2, the road is coming and going of the vehicle, through the window, ambiguously see a family happy *iling face. In this day and age of the quickening pace of life, family members and friends gather to seems very difficult, and the ends of the Chinese New Year is the great moment with family, although I don't understand Chinese mood, but Chinese relatives and friends get together, but it is fun.

In the at 10:07 PM, as the first second street, can use "the whole town turns out" to describe. The street is very cold and cheerless, look, the next street couplet store and a few open restaurant, like the city of Chinese New Year ornament, for this some quiet scene adds a trivial happy expression.

Listen to the elders say they hope is in the New Year, the previous economic conditions as they are now, not so much now thing, every New Year is especially happy you have a new dress, still can and family eat together to enjoy the food on less than. The most important is, to the New Year's eve at night, to "shou sui", each to this time is very good spirit and brothers and sisters do game together chat until the wee hours of the morning, the *s to ShaoZhi money to the deceased ancestors, to twelve point one, and firecrackers are ringing, always when the fireworks gradually sporadic fireworks, lights, gradually dim, and put off, they just quiet down and go to sleep.

And now, all of the living conditions of good, almost every day and New Year's day, the only difference is that with his families a happy! But not everyone can return home for the New Year, some wandering out whether have considered the home of missing loved ones?

Before you know it, blossom again a year, first the expectation can also be back? May the splendid fireworks can reflects bright tonight the dream, a dream countless colorful butterfly flying in the air gorgeous reunion......
