核電站六氟化硫氣體報警系統裝置監控主機

SF6氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)體(ti)(ti)已有百年歷史，它是法國兩位化(hua)學家Moissan和Lebeau于1900年合(he)成的(de)(de)(de)人造惰性氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)體(ti)(ti)，1940年前后，美(mei)國將其(qi)用于曼哈頓計(ji)劃(hua)(核軍事(shi))。SF6是強(qiang)(qiang)電(dian)(dian)(dian)負(fu)(fu)性氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)體(ti)(ti)，它的(de)(de)(de)分(fen)子(zi)極易(yi)吸附自由電(dian)(dian)(dian)子(zi)而形(xing)成質量大的(de)(de)(de)負(fu)(fu)離子(zi)，削(xue)弱氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)碰(peng)撞電(dian)(dian)(dian)離過程，因(yin)此(ci)其(qi)電(dian)(dian)(dian)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)絕緣強(qiang)(qiang)度很高(gao)(gao)，在(zai)均(jun)勻(yun)電(dian)(dian)(dian)場中(zhong)約(yue)為(wei)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)絕緣強(qiang)(qiang)度的(de)(de)(de)2.5倍。SF6氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)體(ti)(ti)在(zai)t≈2000K時出現熱分(fen)解(jie)高(gao)(gao)峰，因(yin)此(ci)在(zai)交流(liu)電(dian)(dian)(dian)弧電(dian)(dian)(dian)流(liu)過零(ling)時，SF6對(dui)弧道(dao)(dao)的(de)(de)(de)冷卻作用比空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)強(qiang)(qiang)得多，其(qi)滅弧能力約(yue)為(wei)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)的(de)(de)(de)100倍。SF6氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)體(ti)(ti)絕緣的(de)(de)(de)管道(dao)(dao)輸電(dian)(dian)(dian)線的(de)(de)(de)優(you)點(dian)是介質損(sun)耗小、傳輸容(rong)量大，且可用于高(gao)(gao)落(luo)差場合(he)，因(yin)此(ci)常用于水電(dian)(dian)(dian)站出線，取代常規的(de)(de)(de)充油電(dian)(dian)(dian)纜。SF6氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)(qi)體(ti)(ti)絕緣的(de)(de)(de)變壓器具有防(fang)火(huo)防(fang)爆。
