供電局sf6氣體檢測報警系統

SF6氣(qi)(qi)(qi)(qi)(qi)體(ti)已有百年歷史，它(ta)是法(fa)國兩位化學(xue)家Moissan和Lebeau于(yu)(yu)1900年合成(cheng)的人(ren)造惰性(xing)(xing)氣(qi)(qi)(qi)(qi)(qi)體(ti)，1940年前后，美國將(jiang)其(qi)用于(yu)(yu)曼哈頓計劃(核(he)軍(jun)事)。SF6是強電(dian)(dian)負(fu)性(xing)(xing)氣(qi)(qi)(qi)(qi)(qi)體(ti)，它(ta)的分子(zi)極易吸附自由電(dian)(dian)子(zi)而形(xing)成(cheng)質量大的負(fu)離子(zi)，削弱氣(qi)(qi)(qi)(qi)(qi)體(ti)中碰撞電(dian)(dian)離過程，因(yin)此其(qi)電(dian)(dian)氣(qi)(qi)(qi)(qi)(qi)絕(jue)緣(yuan)(yuan)(yuan)強度很高，在(zai)(zai)均勻電(dian)(dian)場中約為(wei)空氣(qi)(qi)(qi)(qi)(qi)絕(jue)緣(yuan)(yuan)(yuan)強度的2.5倍。SF6氣(qi)(qi)(qi)(qi)(qi)體(ti)在(zai)(zai)t≈2000K時(shi)出現熱分解高峰，因(yin)此在(zai)(zai)交流(liu)電(dian)(dian)弧電(dian)(dian)流(liu)過零時(shi)，SF6對弧道(dao)(dao)的冷卻作用比空氣(qi)(qi)(qi)(qi)(qi)強得多，其(qi)滅弧能力約為(wei)空氣(qi)(qi)(qi)(qi)(qi)的100倍。SF6氣(qi)(qi)(qi)(qi)(qi)體(ti)絕(jue)緣(yuan)(yuan)(yuan)的管道(dao)(dao)輸電(dian)(dian)線的優點是介質損耗(hao)小、傳輸容量大，且可(ke)用于(yu)(yu)高落(luo)差場合，因(yin)此常(chang)用于(yu)(yu)水(shui)電(dian)(dian)站出線，取代常(chang)規的充油電(dian)(dian)纜。SF6氣(qi)(qi)(qi)(qi)(qi)體(ti)絕(jue)緣(yuan)(yuan)(yuan)的變壓器具(ju)有防火防爆。
