| RW5-35/100A跌落式熔断器RW5-35/200A熔断器 联系人：王总 联系电话：0577-27880112 联系手机：13362763534 一、RW5-35/100A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。跌落式熔断器由绝缘支架和熔丝管二部分组成，静触头安装在绝缘支架两端，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。RW5-35/200A 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，故障电流时熔丝迅速熔断，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，电弧被迅速拉长而熄灭。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，用绝缘杆拉开动触头，此时主动、静动触头仍然接触，继续用绝缘杆拉动触头，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，在电流过零时，将电弧熄灭。RW5-35/200A 二、RW5-35/100A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。RW5-35/200A 三、RW5-35/100A使用条件RW5-35/200A 1.适用于环境温度上限40℃，下限-30℃之内。RW5-35/200A 2.海拔不超过1000m，风速不大于35m/sRW5-35/200A 3.熔断器不适用于下述场所RW5-35/200A 3.1有燃料或爆炸危险的场所。RW5-35/200A 3.2有剧烈震动或冲击的场所。RW5-35/200A 3.3有异电化学气体作用及严重空气污秽，烟雾地区。RW5-35/200A 四、RW5-35/100A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，始终使熔丝处于紧张状态，以保证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，熔丝迅速从灭弧管中抽出，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。 Seven years ago winter, very long, very long. That winter, a little girl, she has lost just long out of a front teeth. For the primary school for her, to her heart cast a shadow over, she can only carry a denture life. From then on, she seemed to go out from what, she liked to lap up, she is always in front of the television stunned, looking at the advertising stunned. She no longer love to talk, she has been desperately trying to hide her defects, she has been that in class she has always been a dispensable role. She was afraid to speak. She is afraid of her shortcomings in front of everyone present. She shunned talk, she hated his name, hate, hate everyone. From that on, her performance was not good. She began to avoid the crowd, she doesn't like in place for one more seconds. Every night, she is crying, she was destined to be a loser. A year later, her father who sent her, her from that for 2 months. Every day, after work everyday. Suffering from the tired, only she knew. Her legs have many scars. She is always a person, silently, quietly... Gradually she used to the life here, accustomed to endure hardships. She began to communicate with them, she likes to communicate with them. Because they don't know her defects. Slowly, she learned to independence, learned to communicate. However, the shadow of the heart, such as a piece of scar tissue, in her mind linger. Back to school, even though she had some change. But, the students seem to have gradually forget her. She has no friends, no friend. Each time in the class organization group activity, she always a person. She is eager to have a metamorphosis, like as a caterpillar transformation. She didn't want her to become a butterfly, but she only hope to be noticed. But, the fact again and again have to beat her. She had hoped that they never didn't was born. When she is a school again a junior high school student, when she towards the colleges, she swore, she must not let history repeat itself. She tried to let everyone remember me, she was afraid you ignore me, afraid she was left alone one. She tried to complete her transformation. She waiting for the new get started. Her efforts to change, she try to forget, she try to adapt. She will make a lot of friends, may be used to the right, she always to the English speaking there is a fear, she was afraid to show themselves. The six months before the military training, that she changed her opinion of himself. That day she in the stomach, she lay in the dormitory. When she woke up, they have come back. Look at them as she played hot meal, and that a few words of simple care. Make her heart appeared long-lost moved. That kind of touched, she has been a long time, without feeling. She didn't know in their heart, there is a place is exclusive to her. She grain not know, she has already the realization of his oath. She element to know, in fact the spring has come to her approximation, but she didn't notice it. The defects made her feel inferior, make her heart snowing. Can this late spring, although be late to but still warm. Make her heart of ice and snow melt, chun nuanhua leaves, the awaken of spring is abundant. Now that girl has no longer since closed, she learned to smile to the life. She became cheerful, like a spring grass rushed out of mud, rushed out of the winter. Although her winter for a long, long time, however, that the late spring will arouse her, the bunch of sunshine, will she winter dispelled, put her warm in winter. Ice and snow melt, the awaken of spring is abundant. |
