核電站sf6在線泄露報警系統報警裝置SF6報警

SF6氣(qi)(qi)(qi)(qi)體(ti)(ti)已有百(bai)年(nian)歷史，它是(shi)法(fa)國(guo)兩位化學家Moissan和Lebeau于1900年(nian)合成(cheng)的(de)(de)(de)(de)人造惰性氣(qi)(qi)(qi)(qi)體(ti)(ti)，1940年(nian)前后，美(mei)國(guo)將其(qi)用于曼哈頓計劃(hua)(核(he)軍事)。SF6是(shi)強(qiang)電(dian)(dian)(dian)(dian)(dian)(dian)負(fu)性氣(qi)(qi)(qi)(qi)體(ti)(ti)，它的(de)(de)(de)(de)分子極易吸附自由電(dian)(dian)(dian)(dian)(dian)(dian)子而形成(cheng)質量大的(de)(de)(de)(de)負(fu)離(li)子，削弱氣(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)碰(peng)撞電(dian)(dian)(dian)(dian)(dian)(dian)離(li)過程，因此其(qi)電(dian)(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)(qi)(qi)絕(jue)緣(yuan)強(qiang)度很(hen)高(gao)，在(zai)均勻電(dian)(dian)(dian)(dian)(dian)(dian)場中(zhong)約為空氣(qi)(qi)(qi)(qi)絕(jue)緣(yuan)強(qiang)度的(de)(de)(de)(de)2.5倍(bei)。SF6氣(qi)(qi)(qi)(qi)體(ti)(ti)在(zai)t≈2000K時出(chu)(chu)現熱(re)分解高(gao)峰(feng)，因此在(zai)交(jiao)流電(dian)(dian)(dian)(dian)(dian)(dian)弧電(dian)(dian)(dian)(dian)(dian)(dian)流過零時，SF6對弧道的(de)(de)(de)(de)冷卻(que)作用比空氣(qi)(qi)(qi)(qi)強(qiang)得多，其(qi)滅弧能(neng)力約為空氣(qi)(qi)(qi)(qi)的(de)(de)(de)(de)100倍(bei)。SF6氣(qi)(qi)(qi)(qi)體(ti)(ti)絕(jue)緣(yuan)的(de)(de)(de)(de)管道輸電(dian)(dian)(dian)(dian)(dian)(dian)線的(de)(de)(de)(de)優(you)點是(shi)介質損耗小、傳輸容(rong)量大，且可用于高(gao)落差場合，因此常(chang)用于水電(dian)(dian)(dian)(dian)(dian)(dian)站出(chu)(chu)線，取代常(chang)規(gui)的(de)(de)(de)(de)充(chong)油電(dian)(dian)(dian)(dian)(dian)(dian)纜。SF6氣(qi)(qi)(qi)(qi)體(ti)(ti)絕(jue)緣(yuan)的(de)(de)(de)(de)變(bian)壓器具(ju)有防火防爆。
