Dab tsi ua rau lub zog poob hauv lub transformer?

Peb txhua tus paub tias cov hloov pauv yog qhov tseem ceeb ntawm cov hluav taws xob. Peb tuaj yeem pom cov kev hloov pauv ntawm cov ncej ntawm txoj kev hauv peb lub neej txhua hnub (Nyem txhawm rau kawm paub dab tsi transformers ntawm ncej yog). Nws txoj haujlwm yog los hloov hluav taws xob ntawm cov voj voog los ntawm kauj ruam ntawm cov hluav taws xob thiab tom qab ntawd sib txuas ntawm qhov hluav taws xob rau kev faib tawm. Txawm li cas los xij, vim cov laj thawj tswv yim (cov khoom siv, tsim qauv, ib puag ncig, thiab lwm yam) efficiency tsis zoo li feem ntau cov khoom siv. Yog li, nkag siab cov laj thawj hloov hluav taws xob tsis muaj zog yog qhov tseem ceeb siv qhov tseem ceeb rau kev txhim kho kev ua haujlwm zoo thiab ua kom zoo dua nws cov kev ua tau zoo.

Hauv tsab xov xwm no, Kuv yuav qhia cov ntsiab lus tseem ceeb uas ua rau lub zog hloov hluav taws xob poob thiab sib tham txog cov hauv kev los txo cov kev poob no. Muaj ntau ntau yam uas tuaj yeem cuam tshuam kev ua haujlwm ntawm kev ua haujlwm ntawm tus hloov pauv, feem ntau yog suav nrog kev tsim qauv ntawm lub transformer, cov ntaub ntawv siv thiab cov haujlwm ua haujlwm. Hauv qab no kuv yuav soj ntsuam cov xwm txheej no los txiav txim siab cov peev txheej tseem ceeb ntawm kev hloov pauv hluav taws xob.

1. Tus qauv tsim thiab kev tsim kho ntawm transformer plays lub luag haujlwm tseem ceeb hauv nws txoj kev ua tau zoo.Piv nrog lwm cov hloov pauv, hloov pauv nrog geometry zoo thiab qhov tsawg kawg nkaus core sib txawv tuaj yeem txo qis hluav taws xob poob. Ib qho zoo - tsim transformer ua kom muaj zog minimal sib txuas thiab ua kom muaj zog sib nqus thiab txhim kho kev siv zog hloov zuj zus. (Yawei Transformermuaj cov kws tsim cov txuj ci tshaj lij thiab yuav muab koj cov kev tsim qauv hloov pauv tshaj plaws)

2. Cov ntaub ntawv siv los ua tus hloov pauv yuav cuam tshuam ncaj qha rau nws txoj kev ua tau zoo.Txij li high - qib silicon steel yog ua los ntawm magnesium cov ntsiab lus uas tau raug xaiv los ua cov khoom siv rau kev ua kom muaj kev poob qis. Rau tib qho laj thawj, siab heev tooj liab lossis aluminium yog xaiv raws li cov khoom winding los txo tusp khaiv poob ntawm lub transformer.

3. Kev khiav hauj lwm muaj kev mob xws li thauj qib thiab qhov kub cuam tshuam rau kev ua haujlwm ntawm cov hloov pauv.Transformers uas ua haujlwm ntawm lossis ze rau kev ntsuas ntsuas hluav taws xob feem ntau ntau dua. Tsis tas li ntawd, yog tias qhov chaw ua haujlwm ntawm lub hloov pauv yog qhov cua tsis zoo lossis qhov hloov pauv tsis zoo thiab ua rau muaj kev phom sij

Lub zog poob ntawm cov hloov pauv tuaj yeem faib tau sib faib ua ob pawg: CREAM poob thiab tooj liab ploj. Nkag siab cov kev poob no yog qhov tseem ceeb rau kev txhim kho kev ua haujlwm hloov pauv. Nov yog txoj hauv kev los txo ob qhov kev poob qis:

1. Txo cov tooj liab ploj

Siv cov ntaub ntawv zoo:Xaiv cov siab siab -}} zoo tooj liab lossis txhuas li cov ntaub ntawv winding los txo kev tiv taus. Vim li cas kev puas tsuaj tawm tsam txo kev poob? Vim tias tiv taus kev tawm tsam ua kev khuam siab kis tau, tsis tseem ceeb ntawm kev tawm tsam thaum tam sim no hla kev yuav txo qis zog thiab ua kom txuag hluav taws xob.

Txhim kho cov qauv WINDING:Siv thicker coils los txo cov kev tawm tsam ntawm cov windings, thiab tsim cov kab cua tsim hluav taws xob tsim nyog los txo txoj kev tam sim no. Tooj liab ploj yog cov cua sov tsim los ntawm cov kev tawm tsam ntawm kev hla dhau ntawm tus neeg xyuas pib. Thaum lub kauj tuab tuab, tus ntoo khaub lig {2} Ntu ntu ntawm tus neeg saib xyuas nce thiab tiv thaiv tsawg zuj zus. Qhov no txhais tau tias thaum tib qho kev hla dhau los ntawm, cov tuab tuab yuav ua tsawg dua cov cua sov. Nyob rau tib lub sijhawm, cov kauj tuab tuaj yeem ua rau cov neeg ua hluav taws kub uas muaj peev xwm txo cov cua sov tshwm sim hauv cov ntom ntom hauv zos. Qhov no pab kom txo qis tag nrho cov cua sov. Tsis tas li ntawd, thicker coils tuaj yeem dissipate tshav kub kom zoo dua, txo qis ntxiv los ntawm kev kub ntxhov. Cov cua sov ua kom sov disspation kev ua tau kev pab ua kom tus neeg xyuas coj ua haujlwm ntawm qhov kub qis dua, yog li kev txhim kho kev ua tau zoo. Qhov kawg taw tes yog txhawm rau txo cov nyuab tawv nqaij: nyob rau hauv high {9} gi} Cov sijhawm ua kom zoo rau saum npoo ntawm tus neeg saib xyuas, uas yog hu ua cov nyhuv tawv nqaij. Thicker coils muab thaj chaw loj dua, txo qhov cuam tshuam ntawm daim tawv nqaij cov nyhuv ntawm kev xa tawm tam sim no thiab yog li txo poob.

2. 2. Cov hlau poob ntawm lub transformer

Siv siab -} Cov ntaub ntawv tseem ceeb tseem ceeb

Tsawg -} Tsis Silicon Steel Los xij:Peb tuaj yeem xaiv qis qis -}}}}}}}}}}}} ut cov ntaub ntawv silicon lossis cov ntaub ntawv uas muaj cov hlau nplaum siab thiab cov herysesis poob. (Hysteresis poob: Lub zog tau noj thaum cov khoom sib nqus yog rov ua dua qub magnetized thiab demagnetized hauv daim teb sib nqus)

Txhim kho Almoy Muaj pes tsawg leeg:Siv cov ntaub ntawv txuam rau cov khoom siv los tiv thaiv eddy tam sim no. (Thaum hloov chaw sib nqus sib nqus ua rau cov khoom nqus sib nqus hauv cov tub ntxhais, cov ntaub ntawv muaj xws li Silicon Steel Ntawv tuaj yeem txo cov txheej txheem siddy tam sim no.)

Siv Laminated Cores

Laminated Tsim:Faib cov ntsiab lus tseem ceeb rau hauv ntau nplooj ntawv nyias nyias, kev tswj hwm ib leeg, txo qhov tsim eddy dej, thiab yog li txo kev poob.

Txhim kho cov qauv tseem ceeb

Tub ntxhais toroidal:Siv lub toroidal lossis kaw tub ntxhais tsim qauv los txhim kho kev ua kom sib luag ntawm cov sib nqus flux thiab txo qis toreakage poob. (Kev xau dej poob: lub zog poob tshwm sim los ntawm kev ua tsis tiav ntawm kev sib nqus. Qhov no lub zog tsis hloov mus rau theem ob.)

Nce cov kev ua haujlwm ntau

Muaj qee kis, nce cov kev ua haujlwm ntau ntawm lub hloov pauv hlau tuaj yeem txo cov hlau loj, vim tias ntawm cov voj highpesy ua me dua thiab poob yuav raug txo kom tsawg dua.

Txo cov kev ua haujlwm kub

Los ntawm kev ua kom txias txias, ua kom cov cua txias ua haujlwm ntawm tus hloov pauv nyob rau hauv ib qho kev haum twg los txo cov kev poob los ntawm kub nce.

Txhim kho cov flux ntom ntom

Tsim Tsim Nyog:Raws li daim ntawv thov ntawm cov hloov pauv, cov flux ntom ntom ntawm cov tub ntxhais yog tsim nyog tsim kom tsis txhob poob ntxiv los ntawm kev ua kom ntev tshaj plaws.

Hais txog cov teeb meem txuj ci ntsig txog kev poob qis xws li kev ua kom zoo dua cov cua txias, txo qhov tsis muaj}} Kev hloov pauv kev ua haujlwm,Yawei transforemrtuaj yeem muab koj cov kev lees paub zoo tshaj plaws thiab kev pabcuam.

Hauv ntej, tus ua haujlwm ua haujlwm yog"Hluav Taws Xob Ua General Generates Magnetism, Hlauletism Tsim Hluav Taws Xob".Yog cov haujlwm ua haujlwm tau txiav txim siab tias tus hloov pauv ntawm 95% thiab 99% Transformers, cov khoom siv tau yuav qis me ntsis, feem ntau ntawm 95% thiab 98%. Rau cov laus dua lossis qis dua- Cov hloov pauv tau zoo, cov khoom siv tau zoo yuav tsawg dua 95%.

Tus ua haujlwm ua haujlwm ntawm cov hloov pauv yog hluav taws xob induction, tab sis nruj me ntsis kev hais lus, nws yog vim kev sib nrig sib hais lus tsis meej. Cov hauv qab no yog kev piav qhia ntawm txoj cai induction thiab kev sib nrig sib tham induction ua:

Lub hauv paus ntsiab lus ntawm indectromagnetic induction: thaum sib nqus flux txuam nrog kev hloov pauv ntawm lub cev (lossis thaum lub zog hluav taws xob hloov pauv tsis tu ncua raug tsim tawm tas li. Nov yog qhov kev piav qhia zoo tshaj plaws ntawm "hluav taws xob hluav taws xob".

Tshwj xeeb, raws li kev sib tw induction lub hauv paus, qhov tam sim no ua rau lub zog hluav taws xob (tsis muaj qhov sib tw ntawm kev hloov pauv ntawm flux sib nqus dhau los ntawm cov kauj. Peb tuaj yeem piav qhia cov lus no ntau intuitively hauv kev ua lej,, where e yog qhov ua rau lub zog hluav taws xob, n yog tus naj npawb ntawm lem ntawm lub kauj, thiabyog tus nqi ntawm kev hloov ntawm cov sib nqus flux.

Cia peb saib ntawm kev sib nrig sib: Hloov cov kauj vab tam sim no hauv cov kauj hauv theem nrab, thiab hloov cov hlau sib nqus hauv cov kauj hauv theem nrab, thiab hloov pauv tam sim no: EMF. Kev sib nrig sib cai yog qhov txiaj ntsig ncaj qha ntawm Faraday Txoj Cai.

Transformers yog qhov piv txwv zoo tshaj plaws ntawm kev sib nrig sib, thiab peb txhais tau tias yog hu ua ib qho kev hloov pauv hluav taws xob (uas peb feem ntau hu "hluav taws xob ua rau muaj hluav taws xob), hlau nplaum tsim hluav taws xob").

Hauv kev nthuav dav, kev tsim tawm Lenz txoj cai lij choj, tam sim no los ntawm kev sib nrig sib cuam tshuam ntawm ob coils (m) Kev sib nrig sib los ntawm ob coils yog tib yam..
