Core Essence: Cov kev ntsuam xyuas niaj hnub ua pov thawj tias txhua chav nyob tsis pub muaj kev tsim khoom yuam kev; hom kev xeem validate qhov kev ntseeg ntawm tus tsim nws tus kheej.Henan Xintailong's 11kv uathiab33kV roj-immersed transformersundergo cov khoom validation thiab Hoobkas kuaj nyob rau hauv nruj raws li ob qho tib si kev xeem regimes.
Txheej txheem cej luam ntawm Qhov Tseem Ceeb Qhov Sib Txawv
| Cov khoom sib piv | Routine Test | Hom Kev Xeem |
|---|---|---|
| Xeem Object | Txhua tus transformer tiav, 100% unit-by-unit test | Ib tus neeg sawv cev piv txwv los ntawm tib cov khoom lag luam, tsis ua rau txhua chav |
| Xeem Lub Hom Phiaj | Tshawb xyuas kev tsim khoom tsis xws li vuam, sib dhos, kev sib txuas, kev rwb thaiv tsev thiab kev poob deviation; txheeb xyuas cov teeb meem ntsig txog txheej txheem | Txheeb xyuas qhov kev tsim qauv tiv thaiv huab cua: muaj peev xwm thermal, rwb thaiv tsev tiv taus, luv-circuit mechanical zog |
| Cov xwm txheej tshwm sim | Yuav tsum tau rau txhua chav ua ntej lub Hoobkas xa khoom; daim ntawv ntsuam xyuas muab nrog rau tus kheej cov cuab yeej | Tshiab khoom validation; Kev hloov kho loj ntawm cov qauv / winding / rwb thaiv tsev; hloov khoom siv; txheem kho dua tshiab; daim ntawv pov thawj txuas ntxiv |
| Qhia qhov tseeb | Daim ntawv qhia tshwj xeeb ntawm chav tsev tsuas yog siv tau rau lub tshuab hluav taws xob nrog tus lej cim no, tsis tuaj yeem rov qab siv dua rau lwm chav. | Daim ntawv pov thawj npog tag nrho cov series raws li zoo tib yam tsim. Cov ntawv pov thawj rau 11kV thiab 33kV tsis tuaj yeem hloov pauv ib leeg |
| Kev kuaj mob | Rated kev khiav hauj lwm mob, tsis muaj huab overload los yog xob laim impulse thov | Simulate qhov xwm txheej phem tshaj plaws: puv-load tas mus li cua sov, xob laim impulse, luv-circuit stress |
| Sijhawm & Nqis | Ob peb teev mus rau 1-2 hnub, ua tiav ntawm cov kab ntau lawm | Lub voj voog ntev: qhov ntsuas kub nce siab yuav siv sijhawm 2-3 hnub; luv luv-circuit xeem yuav tsum tau kuaj thib peb, ob peb lub lis piam ua lub sij hawm nrog tus nqi siab |
I. Routine Test Yam (Yuav tsum tau rau txhua txhua 11kV / 33kV roj-immersed transformer)
Txhua11kv uathiab33kV roj-immersed transformeryuav tsum tau ua tiav cov kev ntsuam xyuas niaj hnub ua ntej tawm hauv lub hoobkas; Txhua yam khoom tuaj yeem pom ntawm -qhov chaw thaum lub Hoobkas Txais Kev Xeem (FAT):
1. Winding DC kuj ntsuas (tag nrho cov kais dej)
2. Voltage ratio ntsuas thiab vector pawg txheeb xyuas
3. Tsis muaj-load poob thiab tsis muaj-load tam sim no ntsuas
4. Load poob thiab luv luv - Circuit Court impedance ntsuas
5. Rwb thaiv tsev tsis kam thiab dielectric poob (tan δ)
6. Siv AC tiv thaiv qhov ntsuas hluav taws xob (lub ntsiab rwb thaiv tsev)
7. Induced withstand voltage test (tig-to-tig/layer-to-layer longitudinal rwb thaiv tsev)
8. Transformer roj ntsuam xyuas (kev tawg voltage, noo noo cov ntsiab lus)
9. Lub tank siab foob thiab kev kuaj xau
10. Tag nrho cov kev ntsuam xyuas ntawm -load tap changer (OLTC) (yog tias nruab nrog OLTC)
Tag nrho cov kev ntsuam xyuas niaj hnub yuav tsum tau ua tim khawv rau txhua 33/11kV transformer thaum lub Hoobkas Txais Kev Xeem (FAT).
II. Yam khoom xeem (Ua tsuas yog rau cov qauv qauv hauv tib koob;11kv uathiab33kv uaunits kuaj cais)
Xintailongtau xaiv cov qauv qauv qauv rau ob chav kawm 11kV thiab 33kV voltage kom ua tiav cov chav kawm tag nrho ntawm hom kev xeem. Cov ntawv pov thawj tsis tuaj yeem hloov pauv hauv cov chav kawm voltage; Cov ntawv luam ntawm cov ntaub ntawv ntsuam xyuas muaj feem yuav muab tau thaum lub sij hawm sib tw:
1. Kev ntsuas kub siab:Rated nruam tas nrho -load haujlwm; ntsuas kub nce ntawm windings thiab sab saum toj - txheej roj los xyuas cov thermal dissipation tsim.
2. Lightning impulse test (LI) (tag nrho yoj + tws yoj):Txheeb xyuas cov rwb thaiv tsev tiv thaiv kev tiv thaiv hluav taws xob overvoltage (33kV BIL siab dua 11kV; hom kev xeem rau ob qho tib si tsis tuaj yeem hloov pauv rau ib leeg).
3. Luv-circuit withstand peev xwm kuaj:Ntsuas cov windings 'tsis kam rau luv luv- Circuit Court electromagnetic rog thiab xyuas rau winding deformation los yog puas tsuaj (feem ntau yog ua nyob rau hauv ib qho kev tso cai thib peb- tog chaw kuaj).
4. Kev ntsuas suab nrov (kev ntsuas suab nrov).
Nco tseg
Hom kev xeem tsis tau ua nyob rau hauv txhua lub tsev tawm hauv lub hoobkas; Tsuas yog cov ntawv luam ntawm hom ntawv pov thawj yuav tsum tau rau kev sib tw. Txawm li cas los xij, ntawm -site Hoobkas Txais Kev Xeem (FAT) tsis tuaj yeem xav tau qhov rov ua dua ntawm qhov kub thiab txias los yog kev ntsuas hluav taws xob ntawm cov khoom xa tawm.
III. Cov ntsiab lus tseem ceeb yooj yim tsis meej pem
1. Daim ntawv pov thawj 11kV hom kev xeem tsis tuaj yeem siv ncaj qha rau 33kV transformer: Cov qib rwb thaiv tsev (BIL) thiab cov chav kawm voltage sib txawv, yog li cov kev xeem sib cais yog qhov yuav tsum tau ua.
2. Hom ntawv xeem ntawv pov thawj tus qauv tsim ua raws; Cov ntawv ceeb toom kev ntsuam xyuas niaj hnub lees paub qhov ua tau raws li qhov tshwj xeeb ntawm chav tsev yuav khoom. Kev twv yuav tsum muaj daim ntawv pov thawj kev xeem, thaum lub Hoobkas xa khoom yuav tsum muaj cov ntawv ceeb toom kev xeem niaj hnub rau chav tsev tshwj xeeb; ob qho tib si yog qhov tseem ceeb.
3. luv- Circuit Court withstand peev yog ib hom kev xeem, tsis yog ib tug niaj hnub xeem; Cov khoom xa tuaj tiag tiag tsis raug luv luv - ntsuas qhov ntsuas hluav taws xob.
4. Ntxiv rau ob pawg no, kuj tseem muaj cov kev ntsuam xyuas tshwj xeeb: FRA winding deformation, ib nrab tso tawm PD, xoom kab ke impedance, thiab lwm yam, uas raug xaiv raws li kev sib cog lus cog lus thiab tsis yog yuav tsum tau ua hom / niaj hnub kuaj.
