高壓柜sf6氣體泄漏在線監測報警系統

SF6氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)已有百年(nian)歷史，它是法國兩位化學家(jia)Moissan和Lebeau于(yu)1900年(nian)合成(cheng)的人造惰性氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)，1940年(nian)前后，美(mei)國將其(qi)用于(yu)曼哈(ha)頓計劃(核軍事)。SF6是強(qiang)(qiang)電(dian)(dian)(dian)(dian)(dian)負(fu)性氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)，它的分(fen)(fen)子(zi)極易吸附自由電(dian)(dian)(dian)(dian)(dian)子(zi)而形(xing)成(cheng)質量(liang)大的負(fu)離子(zi)，削弱氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)中碰撞(zhuang)電(dian)(dian)(dian)(dian)(dian)離過程，因此其(qi)電(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)(qi)絕(jue)緣(yuan)(yuan)(yuan)強(qiang)(qiang)度(du)很高(gao)，在(zai)均勻電(dian)(dian)(dian)(dian)(dian)場中約(yue)為空氣(qi)(qi)(qi)絕(jue)緣(yuan)(yuan)(yuan)強(qiang)(qiang)度(du)的2.5倍。SF6氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)在(zai)t≈2000K時出現熱分(fen)(fen)解高(gao)峰，因此在(zai)交流電(dian)(dian)(dian)(dian)(dian)弧(hu)電(dian)(dian)(dian)(dian)(dian)流過零時，SF6對弧(hu)道(dao)的冷卻作用比空氣(qi)(qi)(qi)強(qiang)(qiang)得多，其(qi)滅弧(hu)能力約(yue)為空氣(qi)(qi)(qi)的100倍。SF6氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)絕(jue)緣(yuan)(yuan)(yuan)的管(guan)道(dao)輸(shu)電(dian)(dian)(dian)(dian)(dian)線的優點是介(jie)質損耗小、傳輸(shu)容量(liang)大，且可用于(yu)高(gao)落差場合，因此常用于(yu)水電(dian)(dian)(dian)(dian)(dian)站出線，取代常規的充油電(dian)(dian)(dian)(dian)(dian)纜。SF6氣(qi)(qi)(qi)體(ti)(ti)(ti)(ti)絕(jue)緣(yuan)(yuan)(yuan)的變(bian)壓器具有防火防爆。

雙(shuang)氣體檢測(ce)器(qi)主要由(you)傳(chuan)(chuan)(chuan)感器(qi)、單(dan)片機、運算放(fang)大電(dian)路、通訊芯(xin)片等組成(cheng)。傳(chuan)(chuan)(chuan)感器(qi)將(jiang)氣體濃度轉(zhuan)換(huan)為模(mo)擬電(dian)信號(hao)，然(ran)后將(jiang)模(mo)擬電(dian)信號(hao)通過(guo)運算放(fang)大電(dian)路、單(dan)片機轉(zhuan)換(huan)為數字信號(hao)，后通過(guo)通訊芯(xin)片轉(zhuan)換(huan)為modbus RTU標(biao)準(zhun)信號(hao)，上傳(chuan)(chuan)(chuan)給控制器(qi)。
