Yuav ua li cas ntsuas qhov ntsuas ntawm transformer?

Ntsuas cov txheej txheem tseem ceeb (tus qauv tsib kauj ruam)
1. Kev sau thiab sau cov ntaub ntawv yooj yim
Cov ntaub ntawv khoom siv: qauv, muaj peev xwm, theem voltage, Hoobkas kuaj cov ntaub ntawv, commissioning hnub, keeb kwm txhaum cai / tu cov ntaub ntawv, yav dhau los xeem ntawv qhia, kais changer hom, txias txoj kev
Kev khiav hauj lwm tej yam kev mob: load rate, voltage fluctuation, ambient kub, kev khiav hauj lwm xyoo, overload / luv Circuit Court tej ntaub ntawv
2. Kev sau cov ntaub ntawv: kev sim offline + saib xyuas online (cov ntaub ntawv tseem ceeb)
(1) Kev tiv thaiv offline (kev kuaj xyuas hluav taws xob, ua tsis tu ncua)
Winding DC tsis kam: Ntsuas txhua theem / kais txoj hauj lwm los txiav txim siab winding vuam, txhuas kev sib cuag, tsis zoo kais hloov kev sib cuag, thiab tig los tig luv luv Circuit Court (tsis sib npaug tsawg dua lossis sib npaug li 2%)
Rwb thaiv tsev tsis kam / nqus piv / polarization Performance index: Txiav txim siab rwb thaiv tsev ya raws, av, thiab kev laus (kev nqus piv Ntau dua lossis sib npaug rau 1.3, polarization Performance index Ntau dua lossis sib npaug rau 1.5)
Dielectric poob yam tseem ceeb (tan δ): ntsuas lub rwb thaiv tsev ntawm windings, bushings, thiab hlau cores, xav txog tag nrho cov deterioration ntawm rwb thaiv tsev thiab noo noo nqus.
Kev hloov pauv, pab pawg xaim, tsis muaj- thauj khoom / thauj khoom: kuaj xyuas qhov txawv txav winding, kev sib txuas, hlau cores, thiab poob
Winding deformation test (frequency response method FRA, short-circuit impedance): los txiav txim seb puas winding deformed los yog hloov los ntawm luv luv-circuit impact
Rwb thaiv tsev roj kuaj: tawg voltage, noo noo cov ntsiab lus, acid tus nqi, interfacial nro, furfural (los txiav txim rwb thaiv tsev ntawv aging)
(2) Kev saib xyuas online (tiag tiag- sijhawm / txuas ntxiv, tsis cuam tshuam)
Dissolved Gas Analysis in Oil (DGA, Core): Monitor H ₂, CH ₄, C ₂ H ₄, C ₂ H ₂, C ₂ H ₆, CO, CO ₂; Siv peb txoj kev sib piv thiab David tus duab peb sab txoj kev los txiav txim siab overheating, low-zog tawm, arc tawm, thiab rwb thaiv tsev ntawv aging
Overheating: CH ₄, C ₂ H ₄ yog qhov tseem ceeb, acetylene tsawg
Arc tso tawm: nce ntxiv hauv acetylene (C ₂ H ₂)
Kev tso tawm ib nrab: hydrogen gas (H ₂) ua cov khoom tseem ceeb
Kev saib xyuas ib nrab (PD) kev saib xyuas: kuaj xyuas qhov tsis xws luag hauv cov rwb thaiv tsev, qhov muaj peev xwm ntab, thiab qhov paug tawm
Kev ntsuas kub: Cov roj kub saum toj kawg nkaus, qhov kub ntawm qhov cua kub, qhov cua txias qhov xwm txheej, txhawm rau txiav txim siab cov cua kub dissipation, overload, thiab overheating hauv zos
Kev vibration / suab nrov xyuas: xoob hlau tub ntxhais, deformed winding, txawv txav fasteners
Kev tshuaj xyuas online ntawm cov roj micro dej thiab roj zoo: taug qab cov qauv ntawm cov rwb thaiv tsev noo noo thiab roj aging
(3) Kev tshuaj xyuas thiab kev ua haujlwm
Roj to, casing puas / paug, kais changer txoj hauj lwm, respirator, txias kiv cua / roj twj, suab nrov txawv txav / tsw, av, SF6 (yog tias muaj) siab, thiab lwm yam
3. Tsim kom muaj ib qho kev ntsuas kev ntsuas hierarchical (raws li cov lus qhia)
Raws li peb qhov - theem qauv ntawm "tag nrho → Cheebtsam → qhov taw qhia", suav nrog 6 core modules, txhua qhov taw qhia muaj qhov ntsuas tus nqi, tus nqi saib xyuas, thiab tus nqi ceeb toom, thiab qib ntawm kev puas tsuaj / qhab nia (0-100 cov ntsiab lus) yog xam:
Lub cev rwb thaiv tsev: rwb thaiv tsev tsis kam tanδ, Roj tawg voltage, micro dej, furfural
Winding: DC tsis kam tiv thaiv tus nqi, luv -circuit impedance, zaus teb yam ntxwv, deformation
Roj Zoo thiab DGA: Gas Composition/Ratio, Oil Aging Index
Lub tes tsho / kais hloov pauv: rwb thaiv tsev, dielectric poob, tiv thaiv kev tiv thaiv
Kev khiav hauj lwm thiab thermal xwm txheej: load, roj kub, kub qhov chaw kub, txias system
Qauv thiab accessories: Hlau core grounding tam sim no, vibration, to, tsos
4. Kev muab qhab nia ntau thiab kev txiav txim siab (lub xeev muab qhab nia)
Kev ntsuas ib leeg: Sib piv cov ntsuas ntsuas nrog tus qauv, suav cov qib ntawm kev puas tsuaj, qhab nia ntawm 0 txog 100 (qhov qhab nia siab dua, lub xeev zoo dua)
Cheebtsam / Tag Nrho Cov Ntsuas Qhov Ntsuas: Muab qhov hnyav raws li qhov tseem ceeb (xws li DGA, winding, thiab rwb thaiv tsev qhov hnyav siab), thiab ntxiv qhov hnyav kom tau txais cov qhab nia zoo
Qib theem (kev lag luam tus qauv qib 4):
Ib txwm: Txhua qhov ntsuas tau tsim nyog thiab tsis muaj qhov txawv txav. Nws tuaj yeem ua haujlwm txuas ntxiv thiab tau txais kev tshuaj xyuas niaj hnub
Ceeb Toom: Qee qhov ntsuas tau ze rau tus nqi saib xyuas, tsis muaj qhov tsis pom tseeb. Shorten lub voj voog saib xyuas thiab taug qab cov qauv
Qhov txawv txav: Ntau qhov ntsuas tau dhau los ntawm tus qauv / qhia pom qhov txawv txav, nrog qhov ua yuam kev. Kev kuaj xyuas hluav taws xob thiab kev saib xyuas yuav raug npaj
Kev hnyav: Cov ntsuas tseem ceeb hnyav dhau tus qauv (xws li acetylene siab, rwb thaiv tsev tawg, winding deformation), kaw tam sim rau kev kho / hloov
5. Kev ntsuam xyuas thiab kev txiav txim siab ua haujlwm thiab kev saib xyuas- ua
Cov ntaub ntawv pov thawj cov xwm txheej ntsuas: cov qhab nia, qib, ntsuas qhov txawv txav, qhov chaw txhaum, theem kev pheej hmoo, kwv yees lub neej seem
Tsim lub tswv yim: Ib txwm → Kev sim tsis tu ncua; Nco ntsoov → Txhim kho kev soj ntsuam; Qhov txawv txav → kev kuaj xyuas hluav taws xob hluav taws xob (xws li cov hlua khi, qhov tso tawm ib nrab); Loj → kaw thaum muaj xwm ceev, kho loj / hloov
2, Cov kev ntsuam xyuas tseem ceeb (feem ntau siv)
DGA diagnostic method (core): roj muaj pes tsawg leeg nyob rau hauv cov roj, roj ntau lawm tus nqi, triple piv, David daim duab peb sab, los txiav txim seb hom ntawm sab hauv overheating / paug txhaum
Fuzzy comprehensive evaluation/Analytic Hierarchy Process (AHP): ntau qhov ntsuas qhov hnyav, fuzzy laj thawj, tuav tsis paub meej, cov qhab nia zoo
Grey correlation / huab qauv: tuav cov ntaub ntawv tsis tiav thiab tsis meej pem, haum rau kev ntsuam xyuas lub xeev
Cov ntaub ntawv tsav tsheb / AI txoj kev: tshuab kev kawm LSTM, Kev sib koom ua ke cov ntaub ntawv keeb kwm / online kom ua tiav lub xeev kev kwv yees thiab ceeb toom txhaum
