核電站SF6+O2雙氣體探頭探測主機安裝

SF6氣(qi)(qi)體(ti)(ti)已有百年歷史，它是法國(guo)兩位(wei)化學(xue)家Moissan和Lebeau于1900年合(he)成(cheng)的人造(zao)惰性(xing)氣(qi)(qi)體(ti)(ti)，1940年前(qian)后，美國(guo)將(jiang)其(qi)(qi)用(yong)(yong)于曼哈(ha)頓(dun)計(ji)劃(核(he)軍事(shi))。SF6是強(qiang)電(dian)(dian)(dian)(dian)負性(xing)氣(qi)(qi)體(ti)(ti)，它的分子極易吸附自由電(dian)(dian)(dian)(dian)子而形(xing)成(cheng)質(zhi)量(liang)大的負離(li)子，削(xue)弱氣(qi)(qi)體(ti)(ti)中(zhong)碰撞電(dian)(dian)(dian)(dian)離(li)過程，因此(ci)其(qi)(qi)電(dian)(dian)(dian)(dian)氣(qi)(qi)絕(jue)緣(yuan)強(qiang)度很(hen)高，在均(jun)勻電(dian)(dian)(dian)(dian)場中(zhong)約(yue)為空氣(qi)(qi)絕(jue)緣(yuan)強(qiang)度的2.5倍。SF6氣(qi)(qi)體(ti)(ti)在t≈2000K時出現熱分解高峰，因此(ci)在交流(liu)電(dian)(dian)(dian)(dian)弧電(dian)(dian)(dian)(dian)流(liu)過零時，SF6對弧道的冷(leng)卻作(zuo)用(yong)(yong)比空氣(qi)(qi)強(qiang)得多，其(qi)(qi)滅弧能力約(yue)為空氣(qi)(qi)的100倍。SF6氣(qi)(qi)體(ti)(ti)絕(jue)緣(yuan)的管道輸電(dian)(dian)(dian)(dian)線的優點是介質(zhi)損(sun)耗小、傳(chuan)輸容量(liang)大，且可用(yong)(yong)于高落差(cha)場合(he)，因此(ci)常(chang)用(yong)(yong)于水電(dian)(dian)(dian)(dian)站出線，取代常(chang)規的充(chong)油電(dian)(dian)(dian)(dian)纜。SF6氣(qi)(qi)體(ti)(ti)絕(jue)緣(yuan)的變壓器具有防火防爆。
