核電站sf6氣體泄漏報警監測檢測儀安裝SF6報警

SF6氣(qi)(qi)(qi)體已(yi)有(you)百(bai)年(nian)歷(li)史，它(ta)(ta)是(shi)法國兩(liang)位(wei)化(hua)學家Moissan和Lebeau于(yu)(yu)1900年(nian)合(he)成的人造惰性(xing)氣(qi)(qi)(qi)體，1940年(nian)前(qian)后，美國將其用(yong)(yong)于(yu)(yu)曼(man)哈頓計劃(核軍事)。SF6是(shi)強(qiang)電(dian)負(fu)性(xing)氣(qi)(qi)(qi)體，它(ta)(ta)的分子極易吸附自(zi)由電(dian)子而形成質量大的負(fu)離(li)子，削弱氣(qi)(qi)(qi)體中(zhong)碰撞電(dian)離(li)過(guo)程，因(yin)此(ci)其電(dian)氣(qi)(qi)(qi)絕(jue)緣(yuan)強(qiang)度很(hen)高(gao)，在(zai)均勻(yun)電(dian)場中(zhong)約(yue)為空氣(qi)(qi)(qi)絕(jue)緣(yuan)強(qiang)度的2.5倍(bei)。SF6氣(qi)(qi)(qi)體在(zai)t≈2000K時(shi)出(chu)現熱分解高(gao)峰，因(yin)此(ci)在(zai)交流電(dian)弧電(dian)流過(guo)零(ling)時(shi)，SF6對弧道的冷卻作用(yong)(yong)比空氣(qi)(qi)(qi)強(qiang)得多，其滅弧能力約(yue)為空氣(qi)(qi)(qi)的100倍(bei)。SF6氣(qi)(qi)(qi)體絕(jue)緣(yuan)的管道輸(shu)電(dian)線(xian)的優點(dian)是(shi)介質損耗小(xiao)、傳輸(shu)容量大，且可用(yong)(yong)于(yu)(yu)高(gao)落(luo)差(cha)場合(he)，因(yin)此(ci)常用(yong)(yong)于(yu)(yu)水電(dian)站出(chu)線(xian)，取代常規的充油電(dian)纜。SF6氣(qi)(qi)(qi)體絕(jue)緣(yuan)的變壓器具有(you)防火防爆。

雙氣體檢測(ce)器主(zhu)要(yao)由(you)傳感器、單(dan)片機、運(yun)算放大電(dian)(dian)路、通(tong)訊(xun)芯片等組成(cheng)。傳感器將(jiang)氣體濃度轉換為(wei)模擬電(dian)(dian)信(xin)號(hao)(hao)，然后將(jiang)模擬電(dian)(dian)信(xin)號(hao)(hao)通(tong)過運(yun)算放大電(dian)(dian)路、單(dan)片機轉換為(wei)數(shu)字信(xin)號(hao)(hao)，后通(tong)過通(tong)訊(xun)芯片轉換為(wei)modbus RTU標準(zhun)信(xin)號(hao)(hao)，上傳給控制器。
