I-single-Isigaba sombane. Injongo, isakhiwo kunye eziphambili neempawu

Kukho ukuqhula endala ziko. Ngomhla umbuzo katitshala "indlela sombane single-isigaba" ndii umfundi ukuphendula: "! Oo-oo-oo". Isandi oku okunene kwenzeka, kungenxa yokuba xa uhambisa kuvela intsimi induction isiphumo striction magnetic, ebangela ipleyiti nendlebe kwisekethe ngemagnethi.

I-single-Isigaba sombane ngenxa odala ombane nokuxuba kuba umthwalo ixabiso olifunayo ngaphandle efuna kwisigaba emithathu-supply amandla.

transformer nganye inamacandelo amabini ezingundoqo: core kwaye jiko kuzo ayikho ngaphantsi kwe ezimbini. Umgaqo tyando elula. Ngenxa yokuphumelela lwangoku zombane ngokusebenzisa umqhubi eziziiprayimari jiko, secondary wayenga amandla electromotive (EMF). Oluphambili iqulathe amacwecwe ferromagnetic, ngamanye nokukhuthaza izinto esomeleza lo mhlaba otsalayo (intsimbi yombane amabakala ezizodwa).

Ubukhulu i-EMF emiselwe yi ifomula:

E = 4,44 x F x f x ω

apho:

F - le awo yokumpompoza magnetic;

f - amaza yangoku;

ω - inani amathuba kwi jiko.

Umthamo umthwalo kuvumelekile, leyo "urhuqa" nesiguquli-single-isigaba, siyinikwe iingcingo candelo, ezithi imibhijelo kunye nemagnethi yesekethe Q kwenxeba, ingakumbi permeability μ ferromagnetic. Engqonge engundoqo kunye nenani engathi efanele ukubala, nto leyo edla isifundo lomsebenzi kwikhosi iiyunivesithi zobugcisa.

Kuyo nayiphi na imeko, i olunye-isigaba sombane ombane enamandla ngakumbi, lo ochukumisa ngakumbi ngobukhulu. Emzimbeni kudla ilayibhuli uluhlu ezingundoqo iparameters (igalelo avumelekile zangoku kunye yombane ifayileyemveliso). Nangona kunjalo, oku akusoloko kunjalo.

Ukuziqhelisa, nabalungisi abaninzi badla ngokujongana imfuneko yokukhupha le ombane sombane single-phase itshiswe-out. Ukwenzela ukuqinisekisa ngokufaneleka kufuneka ihlolwe iimpawu isixhobo, ukuthatha indawo.

Into yokuqala omawuyenze ukugqiba igalelo jiko. Kwinyathelo-phantsi abaguquli iye namandla kakhulu.

Emva koko, siwenze ube womnatha, kunokwenzeka ukuba umlinganiselo ombane imveliso kwi bengasebenzi. Umlinganiselo igalelo kunye neziphumo EMF yi ngumlingani inguqu K. Kwakhona amaqhezu alinganayo Rin N. / N O., ngamanye inani amathuba kwi engathi.

Emva koko, njengoko umthwalo bangathungelana nokumelana enamandla eziguquguqukayo (resistor) kwaye asuse uphawu lwangoku-ombane ngokuthi esicacisa yangoku rated. Njengokuba umthwalo kwandisa ombane output ngcembe kunciphisa.

Abaguquli kukhona amandla nje kuphela, kodwa kananjalo nomlinganiselo. Kwiimeko xa kuyimfuneko ngayo ukuchaza isixa esikhulu ngoku kwisiphaluka usebenzisa ammeter. Ifakiwe ngokulandelelana, kwaye kufuneka babe ukumelana eliphantsi ezidityaniswe esikhulu cross-icandelo wire kwinkqubo aphambuke ngemagnethi. Loo isixhobo bekuya kuba kubiza imali eninzi kwaye omkhulu, ngoko ke sebenzisa ezi-current leyo ukususa bangooceba kwanciphisa ixabiso, kwaye bebanika ukuya ammeters eziqhelekileyo serial. Bala kul ilula, ihlala kuphela basebenzise ezi zinto kwi emzimbeni.
