| HRW4-10/100A跌落式熔断器HRW4-10/200A熔断器 联系人：*总 联系电话： 联系手机： 一、HRW4-10/100A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。HRW4-10/200A 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。HRW4-10/200A 二、HRW4-10/100A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。HRW4-10/200A 三、HRW4-10/100A使用条件HRW4-10/200A 1.适用于环境温度上限40℃，下限-30℃之内。HRW4-10/200A 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HRW4-10/200A 3.1有燃料或*危险的场所。HRW4-10/200A 3.2有剧烈震动或冲击的场所。HRW4-10/200A 3.3有异电化学气体作用及严重空气污秽，烟雾地区。HRW4-10/200A 四、HRW4-10/100A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： In flatly light life, if we watch a little drops of life, you will find, *iling, also is a kind of encouragement. In a game before arrival, as compe*s of I is very nervous, seem to have one thousand jins weight on the shoulder, because of this race relations with my mother and I nearly a month of pay would burn, I really don't want to live up to the expectations of my mother. My mother and I together to ride the jinan is the site, in HouChang area, I very nervous, restless, and mom can't go into the HouChang area, I had to encouraging yourself, the in the mind can get a little comfort. This I play and I was very nervous, for all the judges and audience of the game, I suddenly forget the word in my mind a blank moment, a *all action those lines and vividly in my mouth jumps out. It is my mother, a *ile of contentment on her face appeared, it is full of her encouragement on me and hope. I immediately and confident. In this 1 minutes, 20 seconds I still nervous, 3 seconds is the brain blank, finally the 37 seconds and then let me relax, and also full of confidence. Maybe in the end of the 37 seconds I still have stress and anxiety, but I didn't find that. Mom this short *ile like a persuasive, will my stress and anxiety expelled, light up my brain blank, make the memory to return to my head in. I feel my mother is a fairy, with her XianQi and divine power in the support and protect me, in the encouraged me. A *ile is a kind of encouragement, it is more from relatives and friends, more is give us confidence and relax, happiness and happiness. Smile like a sweet cake, give you happiness and good; Smile like a cup of steaming hot milk tea, give you warm and escape idle; Smile like a lamp that bright light, give you comfort and light; A *ile and you talking and laughing good friend, give you free and happy. I like *iling, difficult for the *ile will shrink back, in fear for the *ile will confidence, family for the *ile will be more fusion, friends for the *ile relaxed, I for the *ile will work harder. Learn to *ile!!!! A *ile is a kind of encouragement! |
