Lub hauv paus rau phau ntawv
Hoobkas txais kev sim tshuaj ntsuam (rog) yog ib qho txheej txheem tswj tseem ceeb rauQhuav -} hom transformers, kom ntseeg tau tias lawv tau raws cov qauv tsim qauv, cov qauv kev nyab xeeb, thiab kev ntseeg tau ua ntej xa khoom. Tsis zoo li roj -}} - Cov khoom siv cua txias, ua rau lawv zoo tshaj rau cov ntaub ntawv sab hauv tsev thiab ib puag ncig. Ib qho kev ua kom muaj kev phom sij me me tsis txaus ntseeg, ua raws liIec, ieee, thiab cov neeg siv khoom xav tau, thiab lav tau ntev ntev-} sij hawm ua haujlwm.
Cov lus qhia no npog lubCov txheej txheem rog ntawm rog, cov qauv kev sim, thiab kev coj ua zoo tshaj plawsRau qhuav -} hom transformers.
Vim li cas cov rog thiaj tseem ceeb rau qhuav -}} hom transformers?
Fool qhia meej tias tus hloov pauv:
✔ Raws Li Cov Qauv Tsim & Daim Ntawv Cog Lus Tshwj Xeeb
✔ Tsis muaj kev lag luam tsis xws luag
✔ Kev khiav haujlwm ruaj khov nyob rau hauv cov xwm txheej
✔ Ua raws li cov qauv thoob ntiaj teb (IEC 60076, IEEE C57.12.01)
Rog rog tuaj yeem ua rauKev ua tsis tiav thaum ntxov, kev nyab xeeb kev nyab xeeb, thiab kim nqiTom qab kev teeb tsa.
Cov kauj ruam tseem ceeb hauv qhuav -} hom rog rog
1. Visual & Kev Tshuaj Kho Tshuab
Ua ntej cov kev kuaj hluav taws xob, kuaj mob lub cev tau ua:
Cov ntaub ntawv xa tawm(KVA, Voltage piv, impedance)
Txheej Txheem Kev Ntseeg(tsis muaj kab nrib pleb, xoob qhov chaw, lossis kev puas tsuaj)
Lub davhlau ya nyob sib txuas & earthing
Cua Txias Zog (Kivcua, Yog Muaj)
2. Rwb thaiv tsev tsis kam kuaj (Megger Test)
Ntsuas tusRwb thaiv tsev zoontawm windings thiab av.
Yam tsawg kawg uas muaj nuj nqis tsim nyog:Ntau dua los yog sib npaug rau 1,000 mω(rau cov hloov pauv tshiab).
Tsawg nyeem qhia cov dej noo lossis paug.
3. Tig tus piv txwv (TTR xeem)
Lees paubVoltage piv raugHla kev windings.
Kev sib txawv dhau±0.5%tuaj yeem qhia luv luv hloov lossis cov kais dej tsis raug.
4. Kev ntsuam xyuas winding
Kuaj xyuasDc kujntawm Thawj & Thib Ob Wirmings.
Txhim kho cov kev sib txuas tsim nyog thiab kuaj pomCov neeg xoob xoob.
5. Dielectric Wallic ToTststand (High -}} tej zaum tau sim)
Yam sivHigh Voltage (AC / DC)los xyuas cov rwb thaiv tsev rwb thaiv tsev.
Ntsuam xyuas voltages:2 X ntsuas voltage + 1}, 000 (IEEE C57.12.91).
6. Kev ntsuam xyuas ua haujlwm (yog tias muaj)
Cua Txias Ntxuam Ua Haujlwm(Rau forced - pa cua txias units).
Kev Ntsuam Xyuas Kub & Tswb Tshuab.
7. Ib nrab kev tawm tsam (yeem rau HV units)
Kuaj pomCov rwb thaiv tsev thaum ntxovnyob rau hauv high - voltage transformers.
Cov Ntaub Ntawv Rog & Ua Raws
Daim ntawv qhia rog rog muaj xws li:
📄 Kev Ntsuam Xyuas Cov Ntawv Qhia Txog Cov Qauv
📄 Daim Ntawv Pov Thawj (ISO, IEC, IEEE ACCOUS)
📄 Tsis - Kev Tshaj Tawm Kev Tshaj Tawm (yog tias muaj)
📄 Cov Neeg Pom Zoo Tso Cai & Tshaj Tawm - tawm
Kev ua kom muaj roj ntau yam kom tsis txhob muaj
❌ Kev kuaj xyuas ib puag ncig ib puag ncig(av noo, hmoov av).
❌ Las mees torque kev txheeb xyuas ntawm kev sib txuas.
❌ Siv cov khoom siv ntsuas cov khoom siv.
❌ Rushing los ntawm kev sim yam tsis muaj ntaub ntawv kom zoo.
