核電站sf6泄漏報警系統探測主機

SF6氣(qi)(qi)體(ti)已有百年(nian)歷史，它是(shi)法國兩位(wei)化學家Moissan和Lebeau于1900年(nian)合成的人造惰性(xing)氣(qi)(qi)體(ti)，1940年(nian)前(qian)后(hou)，美國將其(qi)用于曼哈頓計(ji)劃(hua)(核軍事)。SF6是(shi)強(qiang)電(dian)(dian)(dian)負性(xing)氣(qi)(qi)體(ti)，它的分子(zi)極易(yi)吸附自由電(dian)(dian)(dian)子(zi)而(er)形成質(zhi)量大(da)的負離子(zi)，削弱(ruo)氣(qi)(qi)體(ti)中碰(peng)撞電(dian)(dian)(dian)離過程，因(yin)此(ci)(ci)其(qi)電(dian)(dian)(dian)氣(qi)(qi)絕(jue)緣(yuan)強(qiang)度很高，在均勻電(dian)(dian)(dian)場(chang)中約(yue)(yue)為空(kong)(kong)氣(qi)(qi)絕(jue)緣(yuan)強(qiang)度的2.5倍(bei)。SF6氣(qi)(qi)體(ti)在t≈2000K時出現熱分解高峰(feng)，因(yin)此(ci)(ci)在交流(liu)(liu)電(dian)(dian)(dian)弧(hu)電(dian)(dian)(dian)流(liu)(liu)過零時，SF6對弧(hu)道(dao)的冷卻(que)作用比空(kong)(kong)氣(qi)(qi)強(qiang)得多，其(qi)滅弧(hu)能力約(yue)(yue)為空(kong)(kong)氣(qi)(qi)的100倍(bei)。SF6氣(qi)(qi)體(ti)絕(jue)緣(yuan)的管(guan)道(dao)輸電(dian)(dian)(dian)線的優點是(shi)介質(zhi)損耗小(xiao)、傳輸容量大(da)，且可(ke)用于高落差場(chang)合，因(yin)此(ci)(ci)常用于水電(dian)(dian)(dian)站出線，取代常規的充油(you)電(dian)(dian)(dian)纜。SF6氣(qi)(qi)體(ti)絕(jue)緣(yuan)的變(bian)壓器(qi)具有防(fang)火(huo)防(fang)爆。

雙(shuang)氣體檢測器(qi)(qi)主要由傳感器(qi)(qi)、單(dan)片機、運算(suan)放大電(dian)路、通(tong)(tong)訊芯片等組成(cheng)。傳感器(qi)(qi)將氣體濃度轉換為模(mo)擬(ni)電(dian)信(xin)號，然后將模(mo)擬(ni)電(dian)信(xin)號通(tong)(tong)過(guo)運算(suan)放大電(dian)路、單(dan)片機轉換為數字信(xin)號，后通(tong)(tong)過(guo)通(tong)(tong)訊芯片轉換為modbus RTU標準信(xin)號，上傳給控(kong)制器(qi)(qi)。
