Hloov Kho (Transformer) yog ib qho cuab yeej uas siv lub hauv paus ntsiab lus ntawm electromagnetic induction los hloov AC voltage, cov khoom tseem ceeb yog thawj coil, theem ob kauj thiab hlau core (sib nqus tub ntxhais). Lub luag haujlwm tseem ceeb yog: kev hloov hluav taws xob, kev hloov pauv tam sim no, kev hloov pauv tsis txaus, cais tawm, hluav taws xob lub zog (lub zog sib nqus hloov pauv), thiab lwm yam Nws tuaj yeem muab faib ua lub zog hloov pauv thiab tshwj xeeb hloov hluav taws xob (hluav taws xob ua hluav taws xob transformer, rectifier transformer, hloov hluav taws xob ntau zaus kuaj hluav taws xob, voltage regulator, mining transformer, audio transformer, intermediate zaus transformer, loj zaus transformer, cuam tshuam transformer, ntsuas transformer, hluav taws xob transformer), Reactors, transformers, thiab lwm yam). Cov cim voj voog feem ntau siv T ua qhov pib ntawm tus lej. Piv txwv li: T01, T201, thiab lwm yam.
Tso zis reactor: thaum qhov ntev ntawm cov zis tawm los ntawm inverter rau lub cev muaj zog ntau dua qhov teev nqi ntawm cov khoom, ib qho tso tawm reactor yuav tsum tau ntxiv rau kev them rov qab rau qhov kev cuam tshuam ntawm tus nqi thiab tawm ntawm cov hluav taws xob txuas txuas thaum hluav taws xob cable yog khiav, kom tsis txhob muaj cov hloov inverter. Rau cov zis dv / dt reactor: Txhawm rau txwv qhov tsis nce siab ntawm cov zis hluav taws xob ntawm qhov inverter kom ntseeg tau tias qhov rwb thaiv tsev ntawm lub cev muaj zog. Sinusoidal yoj lim: Ua rau cov zis hluav taws xob thiab qhov tam sim no ntawm lub zog kwv yees rau sine nthwv dej, txo qhov sib haum xeeb tsis sib thooj ntawm lub cev muaj zog thiab lub rwb thaiv tsev siab ntawm lub cev muaj zog. Cov kev xaiv no yuav tsum tau nruab rau ntawm cov zis sab ntawm lub inverter.

Lub tshuab hloov hluav taws xob muaj cov tub ntxhais hlau (lossis cov hlau nplaum sib nqus) thiab lub kauj. Lub kauj muaj ob lossis ntau dua windings. Cov kab hluav taws xob txuas nrog lub fais fab sib txuas yog hu ua thawj kauj, thiab qhov txuas ntxiv windings yog hu ua coil theem nrab. Nws tuaj yeem hloov kho AC voltage, hloov tam sim no thiab cuam tshuam. Qhov yooj yim hlau core transformer yog tsim ntawm ib qho tseem ceeb hlau ua los ntawm cov khoom sib nqus mos thiab ob lub kauj nrog cov sib txawv sib txawv npog cov tub ntxhais hlau.
Lub luag haujlwm ntawm tus tub ntxhais yog ntxiv dag zog rau txoj kev sib nqus sib txuas ntawm ob txheej. Txhawm rau txo qis eddy tam sim no thiab hysteresis poob hauv cov hlau, cov tub ntxhais ua los ntawm laminated silicon steel ntawv; tsis muaj hluav taws xob txuas ntawm ob lub kauj, thiab cov kauj yog ua los ntawm cov kab hluav taws xob tsis muaj hluav taws xob (lossis xov tooj txhuas). Ib qho txuas uas txuas nrog AC lub zog yog hu ua thawj lub kauj (lossis thawj coil), thiab lwm lub txuas uas txuas nrog lub tshuab hluav taws xob yog hu ua lub coil (lossis coil). Qhov hloov pauv qhov tseeb yog qhov nyuaj heev, thiab txhua yam muaj pov thawj tooj liab ploj (cua sov ntawm coil tsis kam), hlau poob (cua sov ntawm cov tub ntxhais hlau) thiab sib nqus sib nqus (sib nqus induction hlau kaw los ntawm huab cua), thiab lwm yam Yuav kom yooj yim kev sib tham, tsuas yog transformer zoo tagnrho yog qhia ntawm no. Cov xwm txheej rau cov hloov hluav taws xob zoo tshaj plaws tau tsim yog: tsis quav ntsej cov xaim xaim hluav taws, tsis quav ntsej qhov tsis kam ntawm cov thawj thiab theem ob txheej, tsis quav ntsej qhov poob ntawm cov tub ntxhais, thiab tsis quav ntsej cov tsis muaj qhov thauj khoom tam sim no (qhov tam sim no hauv thawj kauj ntawm lub theem nrab kauj muaj qhib). Piv txwv li, thaum lub zog hloov hluav taws xob tau khiav ntawm qhov yuav luag tag nrho (qhov ntsuas pa hluav taws xob tso tawm ntawm lub zog hluav taws xob), nws nyob ze rau qhov hloov pauv zoo tagnrho.
Transformers yog cov cuab yeej hluav taws xob zoo nkauj ua siv siv txoj cai ntawm electromagnetic induction. Thaum thawj kauj ntawm cov hloov pauv txuas nrog AC fais fab mov, ib qho hloov sib nqus flux yog tsim nyob rau hauv cov tub ntxhais hlau, uas feem ntau qhia los ntawm φ. Tus φ hauv tus thawj thiab coils coils yog qhov zoo ib yam, thiab φ kuj yog lub suab ua hauj lwm zoo nkauj yooj yim. Lub rooj yog φ = φmsinωt. Raws li Faraday txoj cai ntawm kev siv hluav taws xob hauv lub tshuab hluav taws xob, qhov pib lub tshuab hluav taws xob nyob hauv lub hauv paus tseem ceeb thiab coils yog e1 = -N1dφ / dt thiab e2 = -N2dφ / dt. Hauv tus qauv, N1 thiab N2 yog lem ntawm thawj thiab coils coils. Nws tuaj yeem pom tau tias U1 = -e1 thiab U2 = e2 (qhov ntau ntawm lub cev ntawm lub coil qub yog sawv cev los ntawm subscript 1 thiab qhov ntau ntawm lub cev ntawm lub coil thib ob yog sawv cev los ntawm subscript 2). = N1 / N2, hu ua kev hloov pauv ntawm qhov hloov pauv. Los ntawm cov qauv hais saum toj no, U1 / U2 = -N1 / N2 = -k, uas yog, qhov sib piv ntawm cov txiaj ntsig zoo ntawm kev hloov pauv thawj thiab theem hluav taws xob hluav taws xob sib npaug yog sib npaug rau nws hloov qhov sib piv thiab theem sib txawv ntawm tus thawj thiab theem ob txheej ceev yog π.
Nws tseem hais ntxiv tias:
U1/U2 = N1/N2
Nyob rau hauv rooj plaub uas qhov tsis muaj qhov tso tawm tam sim no tuaj yeem tsis quav ntsej, muaj I1 / I2 = -N2 / N1, uas yog, tus nqi zoo ntawm cov thawj thiab theem nrab coil tam sim no yog inversely proportional rau tus naj npawb ntawm lem thiab theem sib txawv. π.
Nyeg muaj
I1 / I2 = N2 / N1
Lub zog ntawm thawj thiab theem ob txheej ntawm qhov hloov hluav taws xob zoo tagnrho yog sib luag P1 = P2. Nws qhia tau hais tias qhov kev hloov pauv zoo tagnrho nws tus kheej tsis muaj lub hwj chim ploj. Qhov tiag transformer ib txwm muaj poob, thiab nws cov hauj lwm zoo yog η = P2 / P1. Qhov ua tau zoo ntawm lub zog hloov hluav taws xob yog siab heev, nce mus txog ntau dua 90%
Cov yam ntxwv ntawm tus kheej:
zaus ua hauj lwm
Transformer core poob muaj qhov kev sib raug zoo nrog ntau zaus, yog li nws yuav tsum tsim qauv thiab siv raws li kev siv ntau zaus. Cov ntau zaus no hu ua qhov zaus ua haujlwm.
rated hwj chim
Raws li qhov teev tseg zaus thiab qhov voltage, lub tshuab hloov pauv tuaj yeem ua haujlwm tau ntev ntev yam tsis muaj lub zog tso zis ntau dua ntawm qhov kev ntsuas kub siab ntxiv.
nyob voltage
Hais txog qhov hluav taws xob tso cai rau tau thov rau ntawm lub kauj ntawm lub tshuab hloov pauv, uas yuav tsum tsis txhob ntau dua tus nqi tshwj xeeb thaum lub sijhawm ua haujlwm.
Piv rau voltage
Hais txog qhov piv ntawm transformer thawj qhov hluav taws xob thiab theem nrab voltage, muaj qhov sib txawv ntawm qhov tsis muaj- qhov hluav taws xob seem thiab qhov voltage voltage piv.
Tsis muaj-thauj khoom tam sim no
Thaum theem nrab ntawm kev hloov pauv tau qhib, lub hauv paus tseem muaj qee yam tam sim no. Qhov no ntu ntawm qhov tam sim no yog hu ua tsis muaj thauj tawm. Qhov tsis muaj thauj khoom tam sim no yog tsim ntawm cov hlau nplaum tam sim no (tsim hluav taws xob flux) thiab cov hlau poob tam sim no (tshwm sim los ntawm cov tub ntxhais tsis txaus). Rau 50Hz lub zog hloov hluav taws xob, tsis muaj qhov thauj khoom tam sim no qhov sib luag ntawm qhov sib txawv tam sim no.
Thauj khoom poob
Xa mus rau lub hwj chim poob ntsuas ntawm lub thawj thaum lub pob hluav taws xob theem nrab tau qhib. Lub ntsiab poob yog qhov poob qhov tseem ceeb, tom qab los ntawm qhov tsis muaj qhov poob tam sim no (tooj liab poob) ntawm qhov sib txuas ntawm cov xov tooj liab, qhov feem ntawm qhov poob yog me me.
ua hauj lwm zoo
Hais txog qhov feem pua ntawm qhov sib piv ntawm theem nrab lub zog P2 rau thawj lub zog P1. Feem ntau, qhov ntsuas hluav taws xob ntau dua ntawm cov hloov pauv, qhov ua tau zoo dua.
Rwb thaiv tsev kuj
Nws qhia txog kev ua haujlwm rwb thaiv tsev ntawm txhua lub kauj ntawm qhov hloov pauv thiab nruab nrab ntawm txhua lub kauj thiab cov tub ntxhais hlau. Cov qib ntawm rwb thaiv tsev tsis kam cuam tshuam txog qhov ua tau zoo ntawm cov khoom siv insulating siv, qhov ntsuas kub thiab qhov ntsuas noo.
