根據現狀考察點火設備市場,決定采用新型高能點火器裝置。
高能點火器裝置的點火槍火花能量(liang)大(da),具有自凈功能,防潮防雨設計,點火槍長度大(da)于2m,可使電(dian)纜及點火器裝置避(bi)免高溫(wen)輻射、烘烤,高壓電(dian)纜采用硅橡膠耐溫(wen)高壓線(180°C,20kV),高能點火器安裝在筒體底部(bu),不易燒壞且(qie)檢(jian)修(xiu)維護(hu)方(fang)便。
高能點火器裝置的點火原理與噴氣式飛機發動機低壓高能點火裝置相同,其20J點火裝置輸出電流達500mA,脈沖放電單個火花能量可達1.1J。所有在高溫區高壓輸出線路都采取陶瓷絕緣體(95n高鋁瓷管)隔離、采用不銹鋼管保護、及熱密封措施(稱為高壓導電桿),該結構耐高溫、耐腐蝕、防水防潮,點火電極之間鑲有高新材料一半導體材料,使點火電極具有自凈功能、不積碳、不結焦。這種獨特的優越性能是普通高壓點火器裝置所無法比擬的,因此更適用于高空點火。

通過壓力變送器的壓力信號,裝置程控系統可判斷是否有高爐煤氣排放,并根據長明燈的火檢信號判定是否發出點火指令,觸發高能點火裝置是否點燃長火,自動點火系統回到巡檢狀態。若長明燈熄滅,并且仍有高爐煤氣排放時,自動點火系統將重新點燃長明燈。如遇點火故障(有放空高位壓力信號,但長明燈未點燃)則發出聲、光報警信號,報警信號送至裝置程控系統。更多油田專用點火裝置,高能點火器,防爆高能點火器,離子火焰檢測器,紫外火焰檢測器資訊歡迎關注西安軒信電氣科技有限公司。
