Daim Ntawv Qhia Txog Tswv Yim rau IEC 60076: Yam Koj Yuav Tsum Paub Txog
Cia peb ua tiag - fais fab transformers yog kim, hnyav, thiab tseem ceeb heev. Yog tias ib qho ua tsis tau, tej yam yuav ua phem sai. Qhov ntawd yog qhov uas IEC 60076 tuaj txog. Nws yog tus qauv tseem ceeb thoob ntiaj teb rau lub zog hloov hluav taws xob, thiab yog tias koj ua haujlwm hauv thaj chaw, koj yuav tau khiav mus rau nws ntau dua ib zaug.
Tab sis ncaj ncees? Tus qauv nws tus kheej tuaj yeem ua tau me ntsis ntawm cov tsiaj nyaum nyeem. Yog li ntawm no yog ib qho downside -rau- ntiaj teb kev tawg ntawm qhov tseem ceeb, lawv txhais tau li cas, thiab siv lawv li cas yam tsis poob koj lub siab.
Vim li cas Koj Yuav Tsum Saib Xyuas Txog IEC 60076?
Rov qab rau hnub no, txhua tus neeg tsim khoom tau ua lawv tus kheej. Qhov ntawd txhais tau hais tias tsis sib haum xeeb, txoj kev sim txawv txawv, thiab ntau tus ntiv tes - taw tes thaum muaj qee yam tsis raug. IEC 60076 kho feem ntau ntawm qhov ntawd los ntawm kev muab txhua tus neeg ua hom lus.
Nws npog peb thaj chaw loj:
Kev ntsuam xyuas thiab kev tsim qauv- yog li koj paub qhov koj tau txais tiag tiag
Cov kev sim- yog li koj tuaj yeem ua pov thawj nws ua haujlwm
Kev nyab xeeb thiab ib puag ncig cov khoom- zoo li qhov ntsuas kub thiab suab nrov
Yog tias koj tab tom sau qhov kev sib tw, kev xa mus rau tus qauv no ua kom paub tseeb tias kev sib tw sib piv. Yog tias koj yog cov chaw tsim khoom, tom qab ntawd nws zoo nkauj npaum li tus nqi nkag mus rau ntau lub khw.
Qhov tseem ceeb ntawm ib saib
Tsis yog txhua feem ntawm IEC 60076 yog qhov muaj txiaj ntsig zoo sib xws. Nov yog cov uas koj yuav khiav mus rau feem ntau:
Cov khoom tseem ceeb uas koj tsis tuaj yeem tsis quav ntsej
IEC 60076-1 - Lub hauv paus
Nov yog qhov koj pib. Nws qhia koj tias "rated voltage" tiag tiag txhais li cas, cov chav kawm txias zoo li ONAN lossis ONAF ua haujlwm li cas, thiab - qhov no tseem ceeb -kam rau uarau poob.
Piv txwv li:
Tsis muaj - load poob tuaj yeem nce mus txog15% siab duatshaj lav
Load poob tuaj yeem ua tau10% siab dua
Suab nrov? Yog, tab sis qhov ntawd yog tus qauv. Yog tias koj xav kom nruj dua, muab tso rau hauv daim ntawv cog lus.
IEC 60076-3 - Rwb thaiv tsev & kuaj
Qhov no cawm txoj sia (thiab khoom siv). Nws npog qhov siab -voltage tests txhua lub transformer yuav tsum dhau.
xob laim impulse test- mimics xob laim ncaj qha. Yog tias qhov ntsuas hluav taws xob poob qis thaum lub sijhawm kuaj, qee yam tawg. Tsis zoo.
Hloov impulse xeem- rau cov khoom siv hluav taws xob ntau dua (Ntau dua lossis sib npaug ntawm 300 kV). Simulates internal switching surges.
Kev ntsuas ib nrab tso tawm (PD).- qhov no yog ib qho kev sim niaj hnub, lub ntsiab lustxhuaunit tau nws. Koj siv overvoltage thiab xyuas cov me me hauv cov rwb thaiv tsev. Rau cov roj- puv transformers, PD yuav tsum nyob qis dua 100 pC.
Cov lus qhia ceev: tsis txhob hla PD cov cai hauv koj qhov spec. Nws yog ib txoj hauv kev zoo tshaj plaws los ntes kev ua haujlwm tsis zoo thaum ntxov.
IEC 60076-5 - Kev tiv thaiv luv luv
Qhov no yog qhov kev sim siab phem. Nws pib simulates qhov txhaum ntawm lub tshuab hluav taws xob tam sim no - tam sim no loj heev, lub sijhawm luv luv (xws li 0.5 vib nas this lossis tsawg dua). Lub hom phiaj? Xyuas kom cov windings tsis txav los yog tawg.
Vim tias nws kim heev thiab tuaj yeem ua rau lub tsev puas tsuaj, qhov no feem ntau yog akuaj tshwj xeeb, txhais tau tias koj yuav tsum tau thov kom meej meej. Feem ntau cov qauv xa khoom tsis suav nrog nws.
Cov txheej txheem Pass/fail muaj xws li:
Tsawg dua 2% hloov pauv hauv reactance ua ntej vs
Tsis pom winding deformation (yog tias kuaj)
Tsis muaj kev sib tsoo sab hauv
Yog tias koj tab tom yuav transformers rau ib daim phiaj ntxhib nrog kev ua txhaum ntau zaus, ua siab ncaj, koj yuav xav tau qhov kev sim no.
Kev Ntsuas vs. Hom vs. Kev Xeem Tshwj Xeeb – Qhov txawv yog dab tsi?
Tib neeg sib xyaw cov no txhua lub sijhawm. Nov yog qhov yooj yim version:
Yog li yog tias ib tug neeg hais rau koj tias "peb lub tshuab hluav taws xob tau dhau qhov luv luv - Circuit Court test," nug:ntawm chav tsev no, lossis tsuas yog ntawm tus qauv?Qhov txawv loj.
Ib lo lus ntawm Gas -Filled Transformers (IEC 60076-15)
Roj yog tus qauv, tab sis qee zaum koj siv tsis tau nws -xav tias cov chaw nres tsheb hauv av, cov chaw tawm ntug dej hiav txwv, lossis cov chaw uas muaj cov lej hluav taws nruj. Qhov ntawd yog qhov twg cov pa roj- cov tshuab hloov pauv tuaj rau hauv, siv SF₆ lossis cov eco tshiab dua- cov roj hluav taws xob zoo.
IEC 60076-15 yog qhov sib txawv ntawm cov roj tsom mus rau ob peb txoj hauv kev:
Tighter PD txwv (gas tsis tuav sparks thiab)
Kev ntsuam xyuas nruj nruj rau SF₆ (kev tswj hwm ib puag ncig)
Cov cua txias tsawg dua, yog li koj yuav xav tau lub tshuab hluav taws xob loj dua
Yog tias koj yuav roj, nyeem qhov no kom zoo zoo. Tsis txhob cia li xav tias cov kev cai roj siv tau.
Yuav Ua Li Cas Sau Cov Lus Qhia Zoo (Tsis Muaj Kub Kub)
Nov yog qhov yuam kev kuv pom ntau: "Ua raws li IEC 60076." Qhov ntawd yog nws. Vague thiab pheej hmoo.
Ua li no xwb:
Sau cov khoom seem- piv txwv li, 60076-1, -3 (nrog rau kev hloov kho 2018), thiab tej zaum -5.
Qhia cov qib xeem- Tsis txhob xav tias yog BIL lossis PD txwv.
Ua kom pom kev poob siab- tus qauv kam rau ua tej zaum yuav xoob dua li qhov koj xav tau.
Hais txog qhov chaw- yog tias koj nyob ntawm qhov siab lossis qhov kub siab, qhov ntawd tsis yog "ib txwm" raws li tus qauv. Hais li ntawd.
Yuav Ua Li Cas Rau Lwm Cov Qauv
IEEE C57.12-North American nkauj muam nraug nus. Cov npe txias sib txawv, sib txawv kev xeem ua ntu zus. Tsis yog tib yam.
IEC 61869: Ua- uas yog rau cov cuab yeej hloov pauv (VTs thiab CTs), tsis yog lub zog hloov pauv.
ISO 9001 Cov Ntawv Pov Thawj- hais txog kev tswj kom zoo, tsis yog kev ua haujlwm ntawm cov khoom. Tsis txhob nkim lawv.
Ib daim ntawv nthuav dav:IEC 60076-21yog ib qho kev sib koom ua ke nrog IEEE, npog cov kauj ruam-voltage regulators. Qhov ntawd tsim nyog saib yog tias koj ua haujlwm ntawm ob sab ntawm Atlantic.
Kev xav zaum kawg (thiab daim ntawv txheeb xyuas yooj yim)
IEC 60076 tsis zoo tag nrho, tab sis nws yog qhov peb tau txais. Nws ua rau txhua tus muaj qhov pib ncaj ncees. Cia li nco ntsoov: nws yog lub moj khaum, tsis yog daim ntaub thaiv npog. Koj tseem yuav tsum tau sau cov lus qhia meej, nug cov lus nug uas yog, thiab - qhov twg nws tseem ceeb - thov qhov kev xeem tshwj xeeb.
Daim ntawv teev npe ceev ua ntej koj ua tiav koj qhov kev txiav txim transformer tom ntej:
Koj puas tau sau qhov xav tau IEC 60076 qhov chaw los ntawm tus lej?
Koj puas tau hais tias qhov kev xeem twg yog niaj hnub vs. tshwj xeeb?
Koj puas tau teeb tsa qhov siab tshaj plaws PD (hauv pC)?
Koj puas tau kuaj xyuas seb koj qhov chaw nyob yog "ib txwm"?
Yog hais tias luv luv - lub zog hluav taws xob tseem ceeb, koj puas tau nug meej txog qhov kev sim?
