35KV核電站sf6報警在線監測系統

SF6氣(qi)體(ti)(ti)已有百年(nian)歷(li)史，它是法國兩位化(hua)學家Moissan和Lebeau于(yu)1900年(nian)合成(cheng)的(de)(de)人造惰性(xing)氣(qi)體(ti)(ti)，1940年(nian)前(qian)后，美(mei)國將其(qi)用(yong)于(yu)曼(man)哈頓計劃(核(he)軍(jun)事)。SF6是強(qiang)(qiang)電(dian)(dian)(dian)負性(xing)氣(qi)體(ti)(ti)，它的(de)(de)分子(zi)極易吸附自由電(dian)(dian)(dian)子(zi)而形成(cheng)質量大的(de)(de)負離子(zi)，削弱氣(qi)體(ti)(ti)中(zhong)碰撞電(dian)(dian)(dian)離過程，因此其(qi)電(dian)(dian)(dian)氣(qi)絕緣(yuan)強(qiang)(qiang)度很高，在(zai)(zai)均勻電(dian)(dian)(dian)場(chang)(chang)中(zhong)約為空氣(qi)絕緣(yuan)強(qiang)(qiang)度的(de)(de)2.5倍(bei)。SF6氣(qi)體(ti)(ti)在(zai)(zai)t≈2000K時(shi)出現熱(re)分解高峰，因此在(zai)(zai)交流電(dian)(dian)(dian)弧電(dian)(dian)(dian)流過零時(shi)，SF6對弧道(dao)的(de)(de)冷卻作用(yong)比(bi)空氣(qi)強(qiang)(qiang)得多(duo)，其(qi)滅弧能力約為空氣(qi)的(de)(de)100倍(bei)。SF6氣(qi)體(ti)(ti)絕緣(yuan)的(de)(de)管道(dao)輸電(dian)(dian)(dian)線的(de)(de)優點是介(jie)質損(sun)耗小、傳輸容量大，且可用(yong)于(yu)高落差(cha)場(chang)(chang)合，因此常用(yong)于(yu)水電(dian)(dian)(dian)站出線，取代常規的(de)(de)充(chong)油電(dian)(dian)(dian)纜。SF6氣(qi)體(ti)(ti)絕緣(yuan)的(de)(de)變(bian)壓(ya)器具(ju)有防火防爆。
