TusIEC 60076Txheem txhais cov kev txwv thiab kev ua tau zoo rau ob qho hluav taws xob sib txawv, txawm hais tias hom hluav taws xob sib txawv, cov hom hluav taws xob, txias, thiab npaj siv. Below is an overview of typical loss classifications and standards for dry-type and oil-immersed transformers as perIEC 60076.
1. Roj {-}} umped transformers
Roj {-}}}}}}} imm} ackers ras hloov pauv cov ntxhia roj lossis lwm tus insulating kua rau cua txias thiab rwb thaiv tsev. Lawv tau dav siv nyob rau hauv lub zog hluav taws xob rau lawv cov peev xwm siab dua thiab loj dua muaj peev xwm piv rau qhuav- hom transformers.
Cov txheej txheem tsis raug rau cov roj -}}}} umped transformers
Kev tsim nyog muaj feem tau teev los ntawm cov chaw tsim khoom hloov pauv hauv kev ua raws liIEC 60076-1thiabIEC 60076-8Cov. Kev Txwv Txwv Nyob Ntawm:
Kev Ntsuas Hluav Taws Xob: Qhia nyob rau hauv KVA lossis MVA.
Chav Kawm: Feem ntau yog categorized los ntawm high- voltage thiab qis- voltage windings.
Cua Txias Hom: Onan (ROJ Cua Huab Cua Ntuj), onaf (roj cua ua kom haum), thiab lwm yam.
Kev Sib Koom Plawv:
Tsis muaj - phoo ntawv poob:
Tshwm sim vim muaj hlau nplaum ntawm cov tub ntxhais.
Cov ntau yam:0.2% rau 0.3% ntawm rated zog.
Thauj khoom poob:
Suav nrog cov winding ua hauj (i²r poob) thiab poob poob.
Cov ntau yam:0.5% rau 1.5% ntawm rated zog.
Tag nrho cov poob:
Suav ntawm tsis muaj - thau khoom thiab load poob.
Piv txwv li: rau 1 MVA roj -}}} it achers riped transformer:
Tsis muaj {- ntim khoom poob: ~ 1.0 kw
Thauj khoom poob: ~ 7.0 kw
Tag nrho cov kev poob: ~ 8.0 kw
Qib theem ua tau zoo:
Cov roj niaj hnub -}}}} Cov hloov pauv tau tsim los kom tau raws li cov qauv hluav taws xob txuag hluav taws xob, xws liTier 1 lossis theem 2 ua haujlwm hauv kev ua haujlwmhauv iec.
2. Qhuav -} hom transformers
Qhuav -}}}}} hom transformers siv cua lossis lwm yam roj av (piv txwv li, SF6 hauv cov kev rwb thaiv tsev) rau rwb thaiv tsev thiab txias. Lawv feem ntau siv nyob rau hauv ib puag ncig uas muaj kev txhawj xeeb uas muaj kev nyab xeeb thiab ib puag ncig yog qhov tseem ceeb, xws li nyob hauv tsev lossis hauv nruab nrab} kev pheej hmoo.
Cov Qauv Tsis Raug Rau Qhuav -} Hom Transformers
Kev txwv tsis tau teev rau cov chav kawm rwb thaiv tsev sib txawv thiab cov qauv txias:
Kev Ntsuas Hluav Taws Xob: Zoo ib yam li roj -} imm imm imm្ached, qhia nyob rau hauv Kva lossis MVA.
Cua Txias Hom: Ib tug (ntuj ntuj), AF (huab cua yuam).
Kev Sib Koom Plawv:
Tsis muaj - phoo ntawv poob:
Zoo li yuav muaj siab me dua roj -}}}}}} umped transformed transformers vim cov tub ntxhais lub plab ploj.
Cov ntau yam:0.3% rau 0.5% ntawm rated zog.
Thauj khoom poob:
Siab dua me ntsis dua li roj -}}}} aphers ras hloov pauv vim txo qhov kev ua kom txias.
Cov ntau yam:1% rau 2% ntawm rated zog.
Tag nrho cov poob:
Piv txwv li: rau 1 MVA qhuav- hom transform:
Tsis muaj {- ntim khoom poob: ~ 1.5 kw
Thauj khoom poob: ~ 8.0 kw
Tag nrho cov kev poob: ~ 9.5 kw
Qib theem ua tau zoo:
Kev ua tau zoo yog feem ntau qis dua li roj -}}}}} umped transformers. Qhuav -} hom transformers feem ntau tau tsim los sib ntsibChav Kawm AlossisHoob BKev ua haujlwm lub zog ua haujlwm raws li IEC.
IEC poob kev faib tawm
IEC tau qhia cov pawg tsim qauv txheej txheem (piv txwv li,A, B, C, D) rau transformers:
A: Qis poob qis, ua tau zoo tshaj plaws (feem ntau lub zog {{}}} kev tsim qauv).
D: Kev poob siab dua, siv rau tus nqi -}} Zoo tsim hauv tsis- tseem ceeb siv.
Poob qhov tseem ceeb rau roj -}} -}} Hom transformers hauv txhua chav sib txawv raws li:
Kev ntsuas hluav taws xob (piv txwv li, 100 kva, 500 kva, 1 MVA, thiab lwm yam).
Kev ntsuas qib (piv txwv li, 11 kV, 33 kV).
Kev sib piv ntawm kev poob:
| Hloov pauv yam | Tsis muaj {- ntim khoom poob (% ntawm cov rated muaj zog) | Ntsaws poob (% ntawm rated zog) |
|---|---|---|
| Roj -} hip (onan) | 0.2–0.3% | 0.5–1.5% |
| Qhuav - hom (ib) | 0.3–0.5% | 1.0–2.0% |
