核電站sf6六氟化硫監測系統報警裝置

SF6氣(qi)(qi)(qi)(qi)體(ti)(ti)已有(you)百年(nian)歷史，它(ta)(ta)是法國(guo)兩位化學家(jia)Moissan和Lebeau于(yu)1900年(nian)合(he)成(cheng)的人造惰(duo)性氣(qi)(qi)(qi)(qi)體(ti)(ti)，1940年(nian)前后，美國(guo)將(jiang)其用(yong)于(yu)曼哈頓計劃(核(he)軍(jun)事)。SF6是強(qiang)電(dian)(dian)(dian)負(fu)性氣(qi)(qi)(qi)(qi)體(ti)(ti)，它(ta)(ta)的分子極易吸附自由電(dian)(dian)(dian)子而形成(cheng)質量(liang)大的負(fu)離(li)子，削弱氣(qi)(qi)(qi)(qi)體(ti)(ti)中(zhong)碰撞電(dian)(dian)(dian)離(li)過(guo)程，因此其電(dian)(dian)(dian)氣(qi)(qi)(qi)(qi)絕(jue)緣(yuan)強(qiang)度(du)(du)很(hen)高(gao)，在均勻電(dian)(dian)(dian)場中(zhong)約(yue)為(wei)空氣(qi)(qi)(qi)(qi)絕(jue)緣(yuan)強(qiang)度(du)(du)的2.5倍。SF6氣(qi)(qi)(qi)(qi)體(ti)(ti)在t≈2000K時出(chu)現熱分解高(gao)峰，因此在交流電(dian)(dian)(dian)弧電(dian)(dian)(dian)流過(guo)零時，SF6對(dui)弧道的冷卻作用(yong)比(bi)空氣(qi)(qi)(qi)(qi)強(qiang)得多，其滅弧能力約(yue)為(wei)空氣(qi)(qi)(qi)(qi)的100倍。SF6氣(qi)(qi)(qi)(qi)體(ti)(ti)絕(jue)緣(yuan)的管道輸(shu)電(dian)(dian)(dian)線的優點是介質損(sun)耗小、傳輸(shu)容(rong)量(liang)大，且可用(yong)于(yu)高(gao)落差場合(he)，因此常用(yong)于(yu)水電(dian)(dian)(dian)站出(chu)線，取代常規的充油電(dian)(dian)(dian)纜(lan)。SF6氣(qi)(qi)(qi)(qi)體(ti)(ti)絕(jue)緣(yuan)的變壓器具(ju)有(you)防火防爆。

雙氣(qi)體(ti)檢測器(qi)主要由傳感器(qi)、單片(pian)(pian)(pian)機(ji)、運算放(fang)大電(dian)(dian)路(lu)、通訊芯片(pian)(pian)(pian)等組(zu)成(cheng)。傳感器(qi)將(jiang)氣(qi)體(ti)濃度轉(zhuan)換為模擬電(dian)(dian)信(xin)號，然后將(jiang)模擬電(dian)(dian)信(xin)號通過運算放(fang)大電(dian)(dian)路(lu)、單片(pian)(pian)(pian)機(ji)轉(zhuan)換為數字信(xin)號，后通過通訊芯片(pian)(pian)(pian)轉(zhuan)換為modbus RTU標準信(xin)號，上傳給控制器(qi)。
