進線柜(ju)送(song)電操作程(cheng)序(xu)如下
1)大連高低壓開關柜關(guan)(guan)閉所有柜(ju)門及后封板,并鎖好(hao)。(接(jie)地開關(guan)(guan)處于合(he)位時方(fang)可關(guan)(guan)出線柜(ju)下(xia)門)
2)推(tui)上轉運(yun)小車并使其定(ding)位,把(ba)斷路(lu)器手(shou)車推(tui)入(ru)柜(ju)內并使其在試驗位置定(ding)位,(推(tui)斷路(lu)器時需(xu)把(ba)斷路(lu)器兩推(tui)拉(la)把(ba)手(shou)往(wang)中(zhong)間壓,同時用(yong)力往(wang)前(qian)推(tui)(往(wang)柜(ju)內推(tui)),斷路(lu)器到達試驗位置后,放開推(tui)拉(la)把(ba)手(shou),把(ba)手(shou)應自動復位。)手(shou)動插(cha)(cha)上航空插(cha)(cha),關上手(shou)車室門并鎖(suo)好(hao)。
3)觀察上(shang)(shang)柜門各(ge)儀表、信號指示(shi)是否正(zheng)常。(正(zheng)常時綜合(he)繼保電源燈亮,手車試驗位置燈、斷路器分閘指示(shi)燈和(he)儲能(neng)指示(shi)燈亮,如(ru)所有(you)指示(shi)燈均不亮,則打開上(shang)(shang)柜門,確認各(ge)母線電源開關是否合(he)上(shang)(shang),如(ru)已合(he)上(shang)(shang)各(ge)指示(shi)燈仍不亮,則需檢修(xiu)控制回(hui)路。)
4)將斷(duan)路(lu)器手(shou)車搖柄(bing)(bing)(bing)插入(ru)搖柄(bing)(bing)(bing)插口并(bing)用力壓下,順時針(zhen)轉動搖柄(bing)(bing)(bing),約20圈(quan),在搖柄(bing)(bing)(bing)明顯受阻并(bing)伴有“咔嗒”聲(sheng)時取(qu)下搖柄(bing)(bing)(bing),此(ci)時手(shou)車處于(yu)工作位置(zhi),航空插被鎖定,斷(duan)路(lu)器手(shou)車主回路(lu)接通(tong),查看相關信號。(此(ci)時手(shou)車工作位置(zhi)燈(deng)亮,同時手(shou)車試驗位置(zhi)燈(deng)滅。)
5)觀察帶電(dian)(dian)顯示(shi)器(qi),確定外線(xian)電(dian)(dian)源(yuan)已送(song)至本柜(ju)(ju)。(帶電(dian)(dian)顯示(shi)器(qi)面板(ban)開(kai)關壓下為ON位置,如帶電(dian)(dian)顯示(shi)燈亮(liang)表示(shi)外電(dian)(dian)源(yuan)已送(song)至本柜(ju)(ju)斷路器(qi)下觸頭。如帶電(dian)(dian)顯示(shi))燈不亮(liang),則需先送(song)外電(dian)(dian)源(yuan)至本柜(ju)(ju)。)
6)操作(zuo)儀表門上合(he)(he)(he)(he)、分(fen)(fen)轉換(huan)開(kai)關(guan)使斷(duan)路(lu)器合(he)(he)(he)(he)閘(zha)(zha)(zha)送電,同時(shi)(shi)(shi)儀表門上紅(hong)色合(he)(he)(he)(he)閘(zha)(zha)(zha)指(zhi)(zhi)示(shi)燈(deng)(deng)亮(liang),綠色分(fen)(fen)閘(zha)(zha)(zha)指(zhi)(zhi)示(shi)燈(deng)(deng)滅,查(cha)看其(qi)它相關(guan)信(xin)號,一切(qie)正常,送電成(cheng)功。(操作(zuo)合(he)(he)(he)(he)、分(fen)(fen)轉換(huan)開(kai)關(guan)時(shi)(shi)(shi),把操作(zuo)手(shou)柄順時(shi)(shi)(shi)針旋轉至面(mian)板(ban)指(zhi)(zhi)示(shi)合(he)(he)(he)(he)位(wei)置,松開(kai)手(shou)后(hou)操作(zuo)手(shou)柄應自動(dong)復位(wei)至預合(he)(he)(he)(he)位(wei)置。)7)如斷(duan)路(lu)器合(he)(he)(he)(he)閘(zha)(zha)(zha)后(hou)自動(dong)分(fen)(fen)閘(zha)(zha)(zha)或運行中自動(dong)分(fen)(fen)閘(zha)(zha)(zha),則需判斷(duan)何(he)種故(gu)(gu)障(zhang)并排除(chu)后(hou)才(cai)可(ke)按(an)以上程序重新送電。(當線(xian)路(lu)故(gu)(gu)障(zhang)斷(duan)路(lu)器分(fen)(fen)閘(zha)(zha)(zha)后(hou),會發聲光報(bao)警,即(ji)面(mian)板(ban)紅(hong)色故(gu)(gu)障(zhang)指(zhi)(zhi)示(shi)燈(deng)(deng)亮(liang),同時(shi)(shi)(shi)故(gu)(gu)障(zhang)音響鳴(ming)(ming)響。此時(shi)(shi)(shi)觀察綜(zong)合(he)(he)(he)(he)繼(ji)保,如TRIP燈(deng)(deng)亮(liang),同時(shi)(shi)(shi)IL1,IL2,IL3燈(deng)(deng)任一燈(deng)(deng)亮(liang)或同時(shi)(shi)(shi)亮(liang),則故(gu)(gu)障(zhang)為(wei)線(xian)路(lu)過(guo)流,如TRIP燈(deng)(deng)亮(liang),同時(shi)(shi)(shi)IRF燈(deng)(deng)亮(liang),則故(gu)(gu)障(zhang)為(wei)綜(zong)合(he)(he)(he)(he)繼(ji)保異常。在故(gu)(gu)障(zhang)檢(jian)修(xiu)時(shi)(shi)(shi)可(ke)按(an)消音按(an)鈕取消音響鳴(ming)(ming)響,在檢(jian)修(xiu)完(wan)畢后(hou),需按(an)綜(zong)合(he)(he)(he)(he)繼(ji)保面(mian)板(ban)RESET/STEP按(an)鈕手(shou)動(dong)復位(wei)綜(zong)合(he)(he)(he)(he)繼(ji)保。)
