保護(hù)投退基本步驟

熱工保護(hù)投退步序注：一定保證保護(hù)投退記錄本有簽字，做好投退位置/內(nèi)容的記錄，最好在有人監(jiān)護(hù)情況下完成，完成后要進(jìn)行復(fù)查確認(rèn)。保護(hù)投退要避開“與AND”門、“小于”塊、“計(jì)算塊CALC”、“取反NOT”，盡量在“延時(shí)TON”，“脈沖TPULSE”或者“或OR”門解除，但是要注意是否取反（InvIn是否為Ture）?；謴?fù)保護(hù)一定確認(rèn)此信號(hào)沒(méi)有發(fā)出再進(jìn)行確認(rèn)。以#2號(hào)機(jī)組為例：保護(hù)解除后還需從設(shè)備聯(lián)鎖關(guān)中進(jìn)行確認(rèn)，以保證保護(hù)退出無(wú)誤。MFT：2F04/02Software/4201_0001/20MFT_FST'：IN1~IN15通道確定對(duì)應(yīng)通道直接刪除即可。#2機(jī)組MFT保護(hù)設(shè)有投退按鈕在“鍋爐”—“MFT保護(hù)投退監(jiān)視”—“MFT保護(hù)投退按鈕”，打開后直接操作。磨煤機(jī)：分為快停和緊停。以A磨為例快速停磨煤機(jī)保護(hù)名稱路徑解除內(nèi)容給煤機(jī)停延時(shí)120秒2F01/02Softwave/MILLA/4202_0004./#2'../#1.Out一次風(fēng)量<20t/h2F01/02Softwave/MILLA/4202_0004./#5'../#4.Out磨輥軸承溫度高2F01/02Softwave/MILLA/4202_0006/20COALAMGTH'../#4.Out磨煤機(jī)油系統(tǒng)不正常2F01/02Softwave/MILLA/4202_0001/20PLVAOILABNM'../#18.Out相臨兩角火焰信號(hào)喪失2F01/02Softwave/MILLA/4202_0004./#8'../#7.Out磨煤機(jī)潤(rùn)滑油泵停止2F01/02Softwave/MILLA/4202_0004./#11'20NLS2401_O.Out緊急停磨煤機(jī)保護(hù)名稱路徑解除內(nèi)容煤層無(wú)火延時(shí)10秒2F01/02Softwave/MILLA/4202_0004./#24'../#23.Out磨密封風(fēng)/一次風(fēng)差壓低2F01/02Softwave/MILLA/4202_0004./#25'20PdS1402.Out磨煤機(jī)風(fēng)粉門已關(guān)2F01/02Softwave/MILLA/4202_0001/20PLVAOVCTED'../#22.Out磨煤機(jī)出口溫度高2F01/02Softwave/MILLA/4202_0002/20PLVAOTHH'../#11.Out磨煤機(jī)軸承溫度高2F01/02Softwave/MILLA/4202_0006/20COALABEARTH../#14.Out等離子能量失效延時(shí)10秒2F01/02Softwave/MILLA/4202_0004./#27'../#26.OutA磨首出在:2F01/02Softwave/MILLA/4202_0004，B磨首出在:2F01/02Softwave/MILLB/4202_0054，C磨首出在:2F02/02Softwave/MILLC/4202_0104,D磨首出在:2F02/02Softwave/MILLD/4202_0154，E磨首出在:2F03/02software/MILLE/4202_0204,3．送風(fēng)機(jī)：保護(hù)名稱路徑解除內(nèi)容送風(fēng)機(jī)A軸承溫度高二值2B01/02Software/AGSA/DK1-4301-0013./#12'20FDABEARINGTHH.Out送風(fēng)機(jī)A電機(jī)軸承溫度高二值2B01/02Software/AGSA/DK1-4301-0013./#120FDAMOTBEARTHH.Out送風(fēng)機(jī)A油站故障2B01/02Software/AGSA/DK1-4301-0011/20FDASTAFAIL'../#41.Out爐膛負(fù)壓高II值MFT2B01/02Software/AGSA/DK1-4301-0013./#16'../#15.Out引風(fēng)機(jī)A停止2B01/02Software/AGSA/DK1-4301-0013./#17'20NLS4701_C.Out送風(fēng)機(jī)A運(yùn)行60S出口隔絕門未開2B01/02Software/AGSA/DK1-4301-0013./#20'../#19.Out空預(yù)器A停轉(zhuǎn)延時(shí)30秒2B01/02Software/AGSA/DK1-4301-0013./#22'../#21.OutA送：2B01/02Software/AGSA/DK1-4301-0013/20FDAFSTOUT'B送：2B02/02Software/AGSB/DK1-4301-0113/20FDBFSTOUT'引風(fēng)機(jī)：保護(hù)名稱路徑解除內(nèi)容送風(fēng)機(jī)全停停引風(fēng)機(jī)A2B01/02Software/AGSA/DK1-4301-0033./#15'[2F04]20FD_ZT.Out引風(fēng)機(jī)A電動(dòng)機(jī)繞組溫度高二值2B01/02Software/AGSA/DK1-4301-0033./#21'20IDAMOTLOOPTHH.Out引風(fēng)機(jī)A電動(dòng)機(jī)軸承溫度高二值2B01/02Software/AGSA/DK1-4301-0033./#22'20IDAMOTBEARTHH.Out引風(fēng)機(jī)A軸承溫度高二值2B01/02Software/AGSA/DK1-4301-0033./#23'20IDABEARINGHH.Out引風(fēng)機(jī)A運(yùn)行60S出入口門未開2B01/02Software/AGSA/DK1-4301-0033./#40'../#26.Out爐膛負(fù)壓低II值MFT2B01/02Software/AGSA/DK1-4301-0033./#29'../#28.Out空預(yù)器A停轉(zhuǎn)延時(shí)30秒2B01/02Software/AGSA/DK1-4301-0033./#35'../#34.OutA引：2B01/02Software/AGSA/DK1-4301-0033B引：2B02/02Software/AGSB/DK1-4301-0133一次風(fēng)機(jī)：保護(hù)名稱路徑解除內(nèi)容空預(yù)器A停轉(zhuǎn)延時(shí)30秒2B01/02Software/AGSA/DK1-4301-0003./#10'../#9.Out一次風(fēng)機(jī)A軸承溫度高二值2B01/02Software/AGSA/DK1-4301-0003./#11'20PAABEARINGTHH.Out一次風(fēng)機(jī)A電機(jī)軸承溫度高二值2B01/02Software/AGSA/DK1-4301-0003./#12'20PAAMOTBEARTHH.Out一次風(fēng)機(jī)A驅(qū)動(dòng)端軸承振動(dòng)大跳閘2B01/02Software/AGSA/DK1-4301-0003./#14'../#8.Y1一次風(fēng)機(jī)A非驅(qū)動(dòng)端軸承振動(dòng)大跳閘2B01/02Software/AGSA/DK1-4301-0003./#15'../#8.Y2一次風(fēng)機(jī)A運(yùn)行60S出口擋板未開2B01/02Software/AGSA/DK1-4301-0003./#18'../#17.OutA一次風(fēng)：2B01/02Software/AGSA/DK1-4301-0003/B一次風(fēng)：2B02/02Software/AGSB/DK1-4301-0103/給水泵：保護(hù)名稱路徑解除內(nèi)容除氧器水位低低2T01/02Software/BFSPA/DK1-4302-0306./#8'../#7.Out入口流量<140t/h，再循環(huán)閥未開2T01/02Software/BFSPA/DK1-4302-0306./#10'../#9.Y2入口壓力<0.5MPa/2T01/02Software/BFSPA/DK1-4302-0306./#23'../#12.Out潤(rùn)滑油壓力低低T01/02Software/BFSPA/DK1-4302-0302/20MDBFPA_PLL'../#8.Y1溫度不正常2T01/02Software/BFSPA/DK1-4302-0306./#15'20MDBFPATH.OutA泵：2T01/02Software/BFSPA/DK1-4302-0306B泵：2T02/02Software/BFSPB/DK1-4302-0314C泵：2T03/02Software/BFSPC/DK1-4302-0322燃油點(diǎn)火系統(tǒng)試運(yùn)保護(hù)名稱路徑解除內(nèi)容AB油層允許20OABZSPMT強(qiáng)制為tureBC油層允許20OBCZSPMT強(qiáng)制為tureDE油層允許20ODEZSPMT強(qiáng)制為ture油系統(tǒng)正常20OOK強(qiáng)制為tureMFT解除后復(fù)位按鈕解除后，2F04/02Software/4201_0001/20MFT_FST的OprstOprst點(diǎn)tureOFT解除2F04/02Software/4201_0011/20OFT
