Kev tsom xam ntawm cov luv-circuit muaj peev xwm ntawm lub transformer
Lub luv-Circuit haum nrog lub peev xwm ntawm tus hloov pauv tau hais txog nws lub peev xwm thev naus laus zis los ntawm kev ua txhaum luv luv yam tsis muaj kev puas tsuaj tas mus li. Hauv qab no yog cov ncauj lus kom ntxaws:
I.core cov ntsiab lus
1. Luv-Circuit Court Tam Sim No Cov Cwj Pwm
- Thaum lub sijhawm luv dua Circuit Court, qhov tam sim no tuaj yeem ncav cuag 10-25 zaug qhov ntsuas tam sim no, tsim kom muaj qhov kub thiab hluav taws xob siab.
- Asymmetric Cheebtsam: Lub luv luv-Circuit Cotic tam sim no suav nrog DC offset, ua rau kom ntau dua siab dua peak (thawj ib nrab yoj) thiab kev ntxhov siab ntau ntxiv.
2. Cov ntsiab lus tseem ceeb
- Thermal stability: windings yuav tsum tsis tshaj qhov kub tshaj qhov ntsuas ntawm cov ntaub ntawv rwb thaiv tsev (piv txwv li 10 degree rau txhuas) thaum lub sijhawm luv luv-ciurration sijhawm (feem ntau 1-3 feeb).
- Neeg kho tshuab ruaj khov: tsis kam rau deformation, kev hloov pauv, lossis rwb thaiv tsev rwb thaiv tsev los ntawm cov rog hluav taws xob.
II.Influencing yam
1. Cov Qauv Tsim Qauv
- Cuam tshuam voltage (luv-circuit cuam tshuam kev cuam tshuam): ntau dua impedance txwv luv luv corrcuit Court tam sim no tab sis cuam tshuam rau voltage kev cai.
- Tsim qauv qauv: axial compression, winding txhawb nqa (spacers, clamping rings), thiab cov tub ntxhais clamping lub zog.
- Cov khoom xaiv: kev siv tshuab lub zog ntawm kev coj cwj pwm (tooj liab / txhuas) thiab qhov kub tsis kam ntawm Rwb thaiv tsev (piv txwv li Nomex, epoxy).
2. Lwm yam
- System Sai-Muaj peev xwm: Daim phiaj luv-Circuit cov theem tam sim no feem ntau cuam tshuam kev ntxhov siab ntawm tus hloov pauv.
- Kev teb tiv thaiv lub sijhawm: Circuit Court lub sijhawm ua haujlwm lub sijhawm (feem ntau tsawg dua lossis sib npaug nrog 100 ms) txiav txim siab lub sijhawm tsis raug.
Iii.Veb thiab kuaj
1. Cov Qauv Thoob Ntiaj Teb
- iec {{{{{{{}}}: Qhia meej meej cov hau kev kuaj, suav nrog kev ntsuam xyuas thiab asymmetric tam sim no.
- IEEE C57.12. {{{{}}: Yuav tsum tau hloov pauv kom tiv thaiv cov nqi luv luv rau 2 vib nas this yam tsis muaj kev puas tsuaj.
2. Kuaj cov txheej txheem
- Kev ntsuas kev ua ntej: winding tiv taus, impedance, tig piv, thiab rwb thaiv tsev kab mob.
- Luv-Circuit Court Test: Siv cov ntsuas-Circuit Court tam sim no (ncov txog li 2.55 × cov lej symmetric tam sim no) rau 1 thib ob, dua peb zaug.
- Kev ntsuam xyuas tom qab ntawv: Txheeb xyuas cov tshuaj tiv thaiv kab mob tom qab (cov roj pheej nyeem tsis yeem, thiab cov roj-roj (rau cov roj hloov roj).
IV.EnHancement ntsuas
1. Cov qauv kev ua kom zoo
- Radial txhawb nqa lub zog: Siv kev hloov pauv ntawm cov xov tooj lossis cov xov hlau kev ua kom txo qis radial rog.
- Axial compression: pre-ntxhov siab springs lossis hydraulic lub tshuab ua kom ruaj khov windings.
2. Cov khoom nce qib
- Muaj zog ua tus coj zoo: Annealed tooj liab (paib lub zog ntau dua los yog sib npaug rau 90 MPa).
- Kev kub siab rwb thaiv tsev: H-chav kawm (180 degree) lossis rwb thaiv tsev siab dua.
3. Kev tiv thaiv kev sib koom tes
- Kev tiv thaiv zoo sib txawv: lub sijhawm ua haujlwm tsawg dua lossis sib npaug rau 30 ms los txo qis kev txhaum ntev.
- Tam sim no-lim dej reactors: txo cov luv luv cerracuit zaus tam sim no.
V.Type-kev txiav txim siab tshwj xeeb
1. Cov roj hloov roj
- vam khom cov roj ncig ua rau txias; Cov tshuaj ntsuam xyuas roj ntxiv roj (piv txwv li, acetylene nrhiav tau) yog qhov tseem ceeb.
2. Qhuav-hloov pauv
- Yuav tsum muaj cov cua kho kom zoo (piv txwv li, VPI impregnation) kom tiv thaiv hluav taws xob rog.

Ib qho kev hloov pauv cov luv-cov kab ke wasft muaj peev xwm nyob ntawm cov qauv, khoom siv, thiab kev tiv thaiv kev tiv thaiv thiab kev tiv thaiv thiab kev tiv thaiv kev tiv thaiv thiab kev tiv thaiv kev tiv thaiv. Cov neeg tsim khoom lag luam yuav tsum muaj kev cuam tshuam nrog los ntawm kev simulations thiab kev kuaj, thaum cov neeg siv yuav tsum muaj kev tiv thaiv kev ua kom haum nrog cov kab ke. Kev tshawb xyuas ib txwm (piv txwv li, Circuit Court cuam tshuam kev lag luam) yog qhov tseem ceeb kom muaj peev xwm no.
