Peb Theem Transformer Technical Parameters
Peb theem transformer feem ntau yog ib qho cuab yeej siv lub hauv paus ntsiab lus ntawm electromagnetic induction los hloov AC voltage. Lub ntsiab Cheebtsam yog thawj kauj, theem nrab kauj thiab cov tub ntxhais hlau. Lub luag haujlwm tseem ceeb suav nrog kev hloov pauv hluav taws xob, hloov pauv tam sim no, hloov pauv impedance, kev sib cais, kev tswj hluav taws xob (magnetic saturation transformer). Txhawm rau txhim kho kev nkag siab ntawm transformers, transformer manufacturers qhia cov kev tsis zoo ntawm transformers.
Ua ntej, lub ntsiab technical parameters ntawm peb theem transformer:
Nyob rau hauv qhov kev khiav hauj lwm ib puag ncig thiab kev khiav hauj lwm tej yam kev mob ntawm lub transformer, cov ntaub ntawv tseem ceeb yog feem ntau cim rau ntawm lub npe ntawm lub transformer. Feem ntau suav nrog lub peev xwm ntsuas, ntsuas qhov ntsuas hluav taws xob, ntsuas zaus, pawg sib txuas winding, cov ntaub ntawv ntsuas kev ua tau zoo (impedance voltage, tsis muaj load tam sim no, tsis muaj load poob thiab load poob) thiab tag nrho qhov hnyav.
ib. Rated peev (kVA): ntsuas voltage. Lub peev xwm uas tuaj yeem xa tau thaum qhov ntsuas tam sim no ua haujlwm tsis tu ncua.
b. Rated voltage (kV): qhov ua haujlwm voltage uas lub transformer tuaj yeem tiv taus thaum nws ua haujlwm ntev. Txhawm rau ua kom tau raws li qhov xav tau ntawm daim phiaj hluav taws xob hloov pauv, lub siab-voltage sab ntawm transformer muaj cov kais dej, thiab cov zis hluav taws xob ntawm sab qis-voltage yog kho los ntawm kev kho tus naj npawb ntawm cov lem ntawm high-voltage winding.
c. Rated tam sim no (A): Qhov tam sim no tso cai los ntawm lub transformer kom dhau lub sij hawm ntev nyob rau hauv lub rated peev.
d. Tsis muaj-load poob (kW): qhov ntsuas hluav taws xob ntawm qhov ntsuas zaus, siv rau lub davhlau ya nyob twg ntawm ib qho winding, lub zog zoo absorbed thaum cov seem windings tau qhib. Nws muaj feem xyuam rau kev ua tau zoo ntawm cov hlau tub ntxhais silicon steel ntawv, kev tsim khoom thiab kev siv hluav taws xob.
e. Tsis muaj-load tam sim no (feem pua): Thaum peb theem transformer nyob rau hauv qhov ntsuas voltage thiab tsis muaj-load ntawm sab, qhov tam sim no dhau los ntawm winding feem ntau qhia raws li feem pua ntawm cov ntsuas tam sim no.
f. Load poob (kW): Qhov thib ob winding ntawm lub transformer yog luv luv-circuited, thiab transformer chaw tsim tshuaj paus ntseeg hais tias cov rated tam sim no yog dhau los ntawm lub rated kais dej ntawm thawj winding, thiab lub hwj chim noj los ntawm lub transformer lub sij hawm no.
g. impedance voltage (feem pua): Thaum lub thib ob winding ntawm lub transformer yog luv-circuited, qhov voltage yog maj nce los ntawm thawj winding, thiab lub luv luv-circuit tam sim no ntawm lub thib ob winding yog sib npaug zos rau cov rated voltage thov rau thawj sab. Feem ntau qhia raws li feem pua ntawm cov ntsuas hluav taws xob.
h, theem thiab zaus: peb theem pib taw tes yog sawv cev los ntawm s, thiab ib theem pib pib yog sawv cev los ntawm d. Suav teb tus qauv zaus f yog 50Hz. Muaj 60Hz lub teb chaws txawv teb chaws (xws li Tebchaws Meskas).
I. Qhov kub thiab txias: Qhov kub sib txawv ntawm peb theem transformer winding los yog cov roj kub siab thiab ib puag ncig ib puag ncig ntawm lub transformer yog hu ua qhov kub thiab txias ntawm winding los yog cov roj saum npoo. Qhov kub nce txwv ntawm cov roj-immersed transformer winding yog 65K, thiab cov roj saum npoo kub nce mus txog 55K. Kuj tseem muaj ntau txoj kev ua kom txias: roj nws tus kheej txias, yuam cua txias, dej txias, raj, chips, thiab lwm yam.
j. Rwb thaiv tsev qib: Muaj cov txheej txheem rwb thaiv tsev. Cov theem rwb thaiv tsev yog tso tawm raws li hauv qab no: theem rwb thaiv tsev ntawm lub transformer nrog high voltage rated voltage ntawm 35kV thiab ib tug tsawg voltage rated voltage ntawm 10kV yog tso tawm raws li LI200AC85 / LI75AC35. Ntawm lawv, LI200 yog transformer nrog high voltage xob laim impulse withstand voltage ntawm 200kV, hwj chim zaus withstand voltage ntawm 85kV, tsis tshua muaj hluav taws xob xob laim impulse withstand voltage ntawm 75kV, thiab lub hwj chim zaus withstand voltage ntawm 35kV. Tam sim no, theem rwb thaiv tsev ntawm cov khoom siv roj-immersed transformer yog LI75AC35, qhov hluav taws xob siab hluav taws xob tiv thaiv hluav taws xob tiv thaiv hluav taws xob yog 75kV, lub zog hluav taws xob tiv thaiv hluav taws xob yog 35kV, thiab qhov hluav taws xob tsawg yog 400V, uas tuaj yeem tsis quav ntsej.
K. Kev sib txuas pab pawg daim ntawv lo: Raws li cov theem kev sib raug zoo ntawm kev sib tw thib ob, cov khoom siv hluav taws xob hloov hluav taws xob txuas nrog ntau yam kev sib txuas, uas yog hu ua kev sib txuas ntawm pawg windings. Txhawm rau paub qhov txawv ntawm ntau pawg ntawm kev sib txuas, cov cim moos feem ntau siv. Uas yog hais tias, kho tus nqi ntawm cov kab hluav taws xob nyob rau sab high-voltage ntawm lub koob ntev ntawm lub moos thiab 12, thiab siv tus nqi ntawm cov kab hluav taws xob nyob rau sab qis-voltage raws li lub koob luv ntawm lub moos. Yog tias koj pom tus lej twg lub koob luv luv yog, siv nws ua pawg sib txuas.
