Qhov txawv ntawm Auto Transformer thiab Fais Fab Transformer
Lub transformer yog ib qho khoom siv hluav taws xob uas hloov hluav taws xob hluav taws xob los ntawm ib lub voj voog mus rau lwm qhov los ntawm electromagnetic induction. Fais fab transformers thiab nws pib transformers yog ob hom transformers uas feem ntau siv nyob rau hauv lub hwj chim faib systems. Txawm li cas los xij, muaj ntau qhov sib txawv ntawm ob hom kev hloov pauv no.
Lub zog transformer:
Lub hwj chim transformer yog ib hom transformer siv los hloov hluav taws xob hluav taws xob los ntawm thawj winding mus rau theem nrab winding. Lub hauv paus winding txuas nrog lub hauv paus ntawm lub zog hluav taws xob, qhov thib ob winding txuas nrog lub load. Hom transformer no yog siv los nce lossis nqis mus rau theem voltage.
Lub hwj chim transformer muaj ob coils, thawj thiab theem nrab, uas yog lub cev sib cais thiab hluav taws xob rwb thaiv tsev ntawm ib leeg. Qhov voltage yog hloov los ntawm qhov piv ntawm tus naj npawb ntawm lem ntawm ob lub coils. Piv txwv li, yog tias thawj kauj ruam muaj 100 lem thiab lub kauj thib ob muaj 500 lem, qhov voltage yog nce los ntawm ib qho ntawm tsib.
Nws pib transformer:
Ib qho pib transformer, ntawm qhov tod tes, yog ib hom transformer uas muaj ib qho winding uas yog siv los ua ob qho tib si thawj thiab theem nrab winding. Nws yog siv los nce lossis nqis los ntawm qib voltage. Nyob rau hauv ib qho pib transformer, ib feem ntawm cov winding yog sib koom los ntawm ob qho tib si thawj thiab theem nrab circuits. Qhov no yog ua tiav los ntawm kev siv ib co coil nrog ib tug tapping point raws nws ntev. Qhov voltage yog hloov los ntawm qhov piv ntawm tus naj npawb ntawm lem ntawm winding ntawm txawv tapping ntsiab lus.
Qhov sib txawv ntawm Auto transformer thiab Fais fab transformer:
Qhov sib txawv tseem ceeb ntawm qhov pib hloov pauv thiab lub zog hloov hluav taws xob yog qhov pib hloov pauv muaj ib qho winding uas yog siv los ua ob qho tib si thawj thiab theem nrab winding, thaum lub zog hloov hluav taws xob muaj ob qhov sib txawv rau cov thawj thiab theem nrab. Lwm qhov sib txawv yog raws li nram no:
1. Kev tswj hluav taws xob: Lub tshuab hluav taws xob pib muaj kev tswj hwm qhov hluav taws xob zoo dua li lub zog hloov hluav taws xob. Qhov no yog vim hais tias cov kev cai voltage ntawm ib tug transformer yog txiav txim los ntawm tus piv ntawm tus naj npawb ntawm lem ntawm lub hauv paus thiab theem nrab coils. Nyob rau hauv ib qho kev pib transformer, qhov kev hloov pauv yog los ze zog rau kev sib koom ua ke, ua rau muaj kev tswj hwm qhov zoo dua.
2. Tus nqi: Ib qho pib transformer tsis tshua kim tshaj lub hwj chim transformer, raws li nws muaj ib tug winding. Fais fab transformers, ntawm qhov tod tes, muaj ob qhov sib txawv windings uas ua rau tus nqi ntau lawm.
3. impedance: Lub hwj chim transformer muaj lub impedance siab tshaj qhov pib transformer. Qhov no yog vim hais tias ob qhov sib cais windings ntawm lub hwj chim transformer muab kev sib cais thiab txo cov coupling ntawm thawj thiab theem nrab circuits.
Hauv kev xaus, ob qho tib si pib hloov pauv thiab lub zog hloov hluav taws xob yog siv rau kev tswj hwm qhov hluav taws xob hauv lub zog hluav taws xob. Qhov kev xaiv ntawm ob yog nyob ntawm ntau yam, xws li theem ntawm qhov xav tau voltage, tus nqi ntawm kev tsim khoom, thiab qib xav tau ntawm impedance. Zuag qhia tag nrho, kev nkag siab qhov sib txawv ntawm ob hom transformers tuaj yeem pab xaiv qhov tsim nyog transformer rau ib daim ntawv thov.
