10月(yue)22日(ri)，計控電(dian)(dian)儀部301總(zong)變控制室內正(zheng)在進行一(yi)項(xiang)最重(zhong)要的電(dian)(dian)氣檢(jian)(jian)修工(gong)(gong)作——301總(zong)變直(zhi)流屏(ping)升級改造(zao)項(xiang)目。22：30，隨著最后一(yi)組電(dian)(dian)源饋線安全(quan)遷移，301直(zhi)流屏(ping)升級改造(zao)項(xiang)目正(zheng)式圓滿收(shou)工(gong)(gong)，工(gong)(gong)作人(ren)員開始對各個分(fen)支(zhi)回路(lu)進行檢(jian)(jian)查驗證。

301直(zhi)流屏(ping)升級改造項目的準備工(gong)作(zuo)(zuo)在(zai)大檢修(xiu)之(zhi)初就已經開始，在(zai)新配(pei)置(zhi)直(zhi)流屏(ping)安裝到位之(zhi)前，需要(yao)做很(hen)多的準備工(gong)作(zuo)(zuo)。由于直(zhi)流供(gong)電(dian)系統非常(chang)(chang)重(zhong)要(yao)，直(zhi)流屏(ping)運行(xing)的狀(zhuang)態是否良好，直(zhi)接(jie)影(ying)響到總變6千伏電(dian)壓系統以及(ji)全(quan)廠附屬供(gong)電(dian)系統的運行(xing)安全(quan)，直(zhi)流電(dian)源一旦丟失，勢必會造成電(dian)氣綜(zong)合保護裝置(zhi)保護動作(zuo)(zuo)以及(ji)現場供(gong)電(dian)設施斷電(dian)，這將影(ying)響到電(dian)氣設備的正常(chang)(chang)工(gong)作(zuo)(zuo)，直(zhi)接(jie)影(ying)響總體的檢修(xiu)工(gong)作(zuo)(zuo)。因此(ci)計控電(dian)儀部運行(xing)段長趙軍宏一再(zai)強調，必須嚴格執行(xing)電(dian)氣操作(zuo)(zuo)規程，必須做到“重(zhong)視一伸手(shou)，謹(jin)防誤操作(zuo)(zuo)”。

直(zhi)流屏更新(xin)實(shi)施(shi)前(qian)，電(dian)氣運(yun)行(xing)一(yi)班(ban)班(ban)長代曉(xiao)剛制定了(le)一(yi)份詳(xiang)細的(de)工(gong)作(zuo)流程(cheng)(cheng)以及相應的(de)應急措施(shi)，報電(dian)氣運(yun)行(xing)工(gong)段段長趙軍宏處審核，商榷工(gong)作(zuo)明細，確保(bao)檢修工(gong)作(zuo)萬(wan)無一(yi)失。工(gong)作(zuo)時并指(zhi)派專(zhuan)人在(zai)現場負責(ze)施(shi)工(gong)監護，防止(zhi)在(zai)直(zhi)流饋(kui)線在(zai)遷移(yi)過(guo)(guo)程(cheng)(cheng)中(zhong)期間發生誤(wu)操作(zuo)，施(shi)工(gong)過(guo)(guo)程(cheng)(cheng)中(zhong)，必須保(bao)證新(xin)舊裝置在(zai)切換過(guo)(guo)程(cheng)(cheng)中(zhong)均供電(dian)可靠。

10月22日08：00，計控(kong)電(dian)(dian)(dian)(dian)儀部技術人員按照計劃對原有直(zhi)(zhi)(zhi)流屏設備(bei)的線路(lu)進(jin)行(xing)梳(shu)理、標記(ji)；接著，對新安裝直(zhi)(zhi)(zhi)流屏蓄(xu)電(dian)(dian)(dian)(dian)池進(jin)行(xing)安裝，確(que)認蓄(xu)電(dian)(dian)(dian)(dian)池連(lian)接正(zheng)(zheng)確(que)、電(dian)(dian)(dian)(dian)池電(dian)(dian)(dian)(dian)壓極性正(zheng)(zheng)確(que)及電(dian)(dian)(dian)(dian)池巡(xun)檢系統工作(zuo)正(zheng)(zheng)常，并對更新后的直(zhi)(zhi)(zhi)流屏進(jin)行(xing)調試(shi)測試(shi)，使其(qi)工作(zuo)正(zheng)(zheng)常，電(dian)(dian)(dian)(dian)壓參數正(zheng)(zheng)常，確(que)認了直(zhi)(zhi)(zhi)流屏運行(xing)可(ke)靠，直(zhi)(zhi)(zhi)流屏可(ke)有效投入運行(xing)。

接(jie)下來(lai)是最重要的(de)一項(xiang)工作——在直流(liu)(liu)供(gong)電(dian)(dian)饋線(xian)安全供(gong)電(dian)(dian)的(de)情(qing)況下進行安全遷移(yi)，每一回(hui)直流(liu)(liu)線(xian)路，都負(fu)責(ze)十幾(ji)個(ge)電(dian)(dian)力保護器的(de)供(gong)電(dian)(dian)任務(wu)，工作小組的(de)每個(ge)人(ren)都非常認真，不(bu)允(yun)許有(you)誤碰帶電(dian)(dian)部位的(de)情(qing)況。雖(sui)然(ran)制定(ding)了應急措施，但不(bu)能保證(zheng)有(you)意外情(qing)況出現(xian)，施工過程中(zhong)，如果線(xian)路切換過程中(zhong)控制電(dian)(dian)源失效(xiao)，現(xian)場技術人(ren)員要做(zuo)好(hao)在突(tu)發(fa)情(qing)況下供(gong)電(dian)(dian)系(xi)統手(shou)動操作的(de)準備避(bi)免(mian)高(gao)低壓停電(dian)(dian)的(de)情(qing)況發(fa)生。

經過整整一天的(de)加班工(gong)作，晚(wan)上10點(dian)直流屏系(xi)統(tong)的(de)更新(xin)工(gong)作圓(yuan)滿完(wan)成，該項舉(ju)措大(da)大(da)增(zeng)強了公司(si)電(dian)(dian)氣(qi)301總變供電(dian)(dian)系(xi)統(tong)的(de)運(yun)行(xing)可靠性(xing)，為現(xian)場電(dian)(dian)氣(qi)設備安(an)全用電(dian)(dian)提供了有力保障。
