Lub switchgear, raws li lub hauv paus tswj chav tsev ntawm lub hwj chim system, nws installation zoo ncaj qha txiav txim siab stability ntawm lub hwj chim mov thiab kev ruaj ntseg ntawm kev khiav hauj lwm thiab txij nkawm. Raws li kev lag luam txheeb cais, ntau dua 80% tom qab- theem tsis ua haujlwm ntawm lub tshuab hloov pauv (xws li rwb thaiv tsev tawg, kev sib tsoo tshuab, tsis ua haujlwm hauv av, thiab lwm yam) muaj feem xyuam rau kev npaj tsis txaus ua ntej kev teeb tsa. Nws yog ib qho tsim nyog yuav tsum ua raws li 5 yam yuav tsum tau soj ntsuam cov txheej txheem hauv qab no, uas tuaj yeem tiv thaiv kev nyab xeeb ntawm qhov chaw.
1. Kev Tshawb Fawb Txog Cov Khoom Siv: Kev txheeb xyuas cov ntaub ntawv, qauv, thiab lub tshuab ua haujlwm
Lub hom phiaj tseem ceeb: Kom paub meej tias cov cuab yeej ua tau raws li cov qauv tsim, tsis muaj kev thauj mus los tsis zoo lossis tsis zoo.Key cov ntsiab lus los xyuas: Tshawb xyuas cov ntaub ntawv tseem ceeb xws li daim ntawv pov thawj ntawm lub Hoobkas thiab hom ntawv xeem kom paub tseeb tias tsis muaj "tsis yog-" cov ntawv lo; Kev sib raug zoo ntawm daim ntawv teev npe: Paub meej tias lub txee qauv, CT / VT piv / qib raug, busbar cross-sectional specification, thiab lwm yam. yog tag nrho raws li cov qauv kos duab, tshwj xeeb tshaj yog rau12 kV hloovthiab33 kV GIS substationcov khoom siv uas muaj qhov sib txawv thiab cov qauv tsim nyog; Paub meej qhov tsos thiab kev huv huv ntawm cov khoom.
2. Installation Environment Verification: Tsim ib qho chaw tsim nyog
Lub Hom Phiaj Tseem Ceeb: Xyuas kom meej tias qhov chaw teeb tsa ua tau raws li qhov yuav tsum tau ua ntawm cov cuab yeej siv, thiab zam kev ua tsis tiav los ntawm ib puag ncig.Key Cov ntsiab lus rau Kev Tshawb Fawb: Kev Ua Haujlwm Hauv Tsev: Kev tsim kho lub ru tsev thiab hauv pem teb yog ua tiav yam tsis muaj qhov xau, txheej txheej sab hauv tsev tiav lawm, cov kab trenches tsis muaj dej los yog khib nyiab, thiab ua ntej - cov khoom siv hauv vaj tse thiab kev ua raws li cov qauv tsim; Kev huv huv ua tau raws li cov qauv, tsis muaj plua plav lossis roj corrosive- rau siab - cov khoom siv hluav taws xob xws li35 kV hloovthiab33 kV GIS substationYuav tsum tau kuaj xyuas ntxiv ntawm airtightness thiab plua plav tiv thaiv kom tsis txhob muaj cov kab mob sab nraud nkag mus rau hauv lub hauv paus tseem ceeb; Kev Tshawb Fawb Lub Hauv Paus Hlau: Tshawb xyuas tias cov kab rov tav ntawm lub hauv paus steel yog tsawg dua lossis sib npaug li 1mm / m, qhov siab sib txawv yog ± 5mm, sab saum toj yog 10-20mm siab dua li cov chaw tsim khoom hauv av ', thiab ua raws li qhov yuav tsum tau ua. Kev ruaj khov yam tsis muaj loosening.Passing Criteria: Kev ua tiav ntawm lub tsev ua haujlwm, qhov chaw qhuav thiab huv si, thiab kev teeb tsa ntawm lub hauv paus steel raws li specifications.Risk ceeb toom: Cov dej noo thiab plua plav ib puag ncig yog nquag ua rau rwb thaiv tsev ya raws, thiab cov hauv paus tsis sib xws tuaj yeem ua rau tsis sib xws ntawm lub txee, cuam tshuam rau kev ntseeg siab ntawm kev siv tshuab.
3. Kev txheeb xyuas ntawm Accessories thiab Fasteners: Cov ntsiab lus txiav txim siab kev teeb tsa zoo
Lub Hom Phiaj Core: Xyuas kom txhua yam khoom siv ua tiav thiab ua raws, thiab tsis txhob cuam tshuam kev ua haujlwm tag nrho vim muaj teeb meem me me. Cov ntsiab lus tseem ceeb rau Kev Tshawb Fawb: Cov Khoom Siv Kom Zoo: suav cov khoom tseem ceeb (xws li cov hluav taws xob hluav taws xob thiab cov hluav taws xob sib cais rau12 kV hloov) thiab cov ntaub ntawv pabcuam kom ntseeg tau tias tsis muaj cov khoom ploj lossis puas lawm; Fastener Ua raws: Tag nrho cov fasteners yuav tsum tau ua los ntawm cov khoom siv galvanized lossis los tiv thaiv - cov ntaub ntawv corrosion, nrog rau cov kev qhia tshwj xeeb (xws li M12 lossis cov bolts loj dua rau kev kho cov txee), thiab tsis yog - cov khoom siv yog nruj me ntsis txwv tsis pub; Kev soj ntsuam hauv av PE Confirmals, raws li cov qauv hauv av Cov qauv, cov ntsiab lus sib txuas tsis muaj xeb, thiab cov tin-plating kev kho mob tiav.Passing Criteria: Ua kom tiav cov khoom siv, cov hlua khi ua raws, thiab cov khoom siv hauv av tsis zoo. Cov lus ceeb toom: Rusty los yog tsis yog- cov hlua khi ua tau zoo tuaj yeem ua rau lub txee kom xoob, thiab cov khoom siv hauv av tsis zoo tuaj yeem ua rau hluav taws xob poob siab.
4.Rwb thaiv tsev thiab Grounding Performance Testing: Nyob hauv thaj tsam nyab xeeb
Lub hom phiaj tseem ceeb: txhawm rau txheeb xyuas qhov kev ntseeg tau ntawm cov rwb thaiv tsev thiab kev sib txuas hauv av, thiab tshem tawm cov kev pheej hmoo ntawm kev xau lossis luv luv Circuit Court. Cov ntsiab lus tseem ceeb ntawm Kev Tshawb Fawb: Kev Ntsuas Hluav Taws Xob: Rau siab - cov khoom siv hluav taws xob zoo li33 kV GIS substation, siv 2500V megohmmeter txhawm rau txheeb xyuas lub hauv paus Circuit Court, kom ntseeg tau tias cov rwb thaiv tsev tsis muaj tsawg dua 100MΩ uas tsis muaj qhov tawg lossis qhov tshwm sim tshwm sim; Kev Ntsuas Kev Sib Txuas Ntxiv: Siv cov kev ntsuas txuas ntxiv ntawm multimeter los ntsuas kev sib txuas ntawm lub txee lub cev, lub qhov rooj thiab lub hauv paus ntsiab lus.Pre{{3} Kev ntsuas qhov ntsuas hluav taws xob txuas ntxiv. Nyob rau hauv cov circuits tseem ceeb kom ntseeg tau tias tsis muaj rwb thaiv tsev tsis muaj zog.Pass Criteria: Rwb thaiv tsev kuj ua tau raws li tus qauv, grounding conductivity yog zoo, thiab tsis muaj rwb thaiv tsev tsis xws luag.Risk ceeb toom: rwb thaiv tsev tsis ua hauj lwm yog lub ntsiab ua rau switchgear burnout, thiab grounding tsis ua hauj lwm ncaj qha hem tus kheej kev ruaj ntseg ntawm cov neeg ua haujlwm tu.
5. Kev Tshawb Nrhiav Thaum Ntxov ntawm Kev Ua Haujlwm Kev Nyab Xeeb
Lub hom phiaj tseem ceeb: txhawm rau txheeb xyuas qhov kev ntseeg tau ntawm kev siv tshuab thiab kev tswj hluav taws xob ua ntej kev teeb tsa.Key Cov Ntsiab Lus rau Kev Tshawb Fawb: Kev Ntsuas Kev Ua Haujlwm: Rau35 kV hloov, manually lossis hluav taws xob ua haujlwm ntawm lub Circuit Court breaker thiab disconnect switch rau tsawg kawg yog 5 zaug, ua kom muaj kev ua haujlwm zoo yam tsis muaj qhov nplaum, thiab qhov tseeb ntawm qhov qhib thiab kaw txoj haujlwm; Interlock Function Verification: Kuaj "tsib-kev tiv thaiv" interlocks kom ntseeg tau 100% kev ua tau zoo thiab tsis muaj qhov ua tau zoo ntawm kev ua haujlwm tsis raug; Secondary Circuit Court raug kho fais fab - ntawm kev ntsuam xyuas ntawm cov cuab yeej tiv thaiv, lub teeb qhia, thiab cov cuab yeej los xyuas kom meej raws li lub xeev tiag tiag.Passing Criteria: Kev ua haujlwm zoo sib xws, kev cuam tshuam zoo, thiab ib puag ncig Circuit Court.Risk Ceeb Toom: Kev ua haujlwm tsis zoo tuaj yeem ua rau kev hloov pauv tsis ua haujlwm, cuam tshuam tsis ua haujlwm tuaj yeem ua rau kev ua haujlwm tsis raug, thiab tsis raug rau cov khoom siv tiv thaiv Circuit Court tsis raug.
5 qhov yuav tsum tau kuaj ua ntej txhim kho lub switchgear tsis yog tsuas yog kev siv nruj ntawm lub teb chaws cov qauv, tab sis kuj muaj kev tswj xyuas zoo ntawm kev ua haujlwm tom qab thiab cov nqi kho mob. Los ntawm tag nrho - txheej txheem tswj kev lees paub cov khoom siv, kev txheeb xyuas ib puag ncig, kev txheeb xyuas cov khoom siv, kev ntsuas rwb thaiv tsev thiab hauv av, thiab kev rov ua haujlwm, qhov kev pheej hmoo tsis ua haujlwm tuaj yeem raug txo los ntawm ntau dua 90%. Nws raug pom zoo tias chav tsev tsim kho tsim cov ntaub ntawv tshuaj xyuas tshwj xeeb thiab khaws cov ntaub ntawv xeem thiab cov ntaub ntawv duab kom ntseeg tau tias txhua kauj ruam ntawm kev ua haujlwm yog traceable.
Yog tias koj xav tau ib txoj kev npaj tsim kho tus kheej rau lub switchgear los yog ntsib teeb meem hauv cov txheej txheem tshuaj xyuas, koj tuaj yeem tiv tauj peb cov kws tshaj lij Suav chaw tsim khoom ntawm switchgears, LVMA Electrical Company, uas muaj ib pab neeg ua haujlwm zoo los muab kev txhawb nqa, ua rau kev ua haujlwm ntawm lub zog muaj kev nyab xeeb thiab ruaj khov.
