Los abaguquli (Njengesiguquli se-toroidal) zezi zixhobo esisetyenziswa ngokubanzi kwizixhobo ezininzi. Ngokukodwa kwezo zisebenzisa i-DC, kuba zivumela ukusuka kumanqanaba aphezulu othungelwano lombane apho ezi zixhobo zidityaniswe khona kwimilinganiselo esezantsi apho zihlala zisebenza khona (12v, 5v, 3.3v ...) kwaye zitshintshe zisuke kwi-AC ukuya kwi-CC usebenzisa onke amanqanaba e ukuhambisa umbane.

Ukubaluleka kwayo kufanelekile ukuba uyazi indlela esebenza ngayo olu hlobo lwesiguquli kunye nokusetyenziswa kwazo, kunye nokuba ungayithenga njani enye yazo kwiiprojekthi zakho, njl. Onke amathandabuzo aya kusonjululwa ngesi sikhokelo ...

## Yintoni isiguquli?

Un umguquli Yinto evumela ukuba kudlule kumandla ombane atshintshanayo aye kwinto eyahlukileyo. Inokutshintsha ubungqingqwa bangoku. Nokuba yeyiphi indlela, iyakuhlala igcina isantya somqondiso kunye namaxabiso ombane angahambelani. Oko kukuthi, ukwenziwa rhoqo kunye namandla ...

Le parameter yokugqibela ayinyani, iya kuba kwisiguquli esifanelekileyo sethiyori, kuba xa kusenziwa kukho ilahleko ngohlobo lobushushu, Enye yeengxaki ezinkulu zala macandelo. Kungenxa yoko le nto isuselwe ekusebenziseni ii-cores eziqinileyo zokwenza i-laminating them (i-silicon steel sheet ene-insulation phakathi kwazo) ukunciphisa i-eddy currents okanye i-parasitic currents.

Ukufezekisa injongo yayo, umbane ongena ngegalelo lokwenza amagqabi uguqulwa ube umazibuthe ngenxa jiko kunye core intsimbi. Emva koko, ubutsalane obuhamba kumbindi wentsimbi buya kubangela amandla ombane okanye wombane kumjikelo wesibini ukubonelela okwangoku kwimveliso. Ewe, ucingo oluqhubayo lwe-windings lunoluhlobo lwe-varnish yokwambathisa ukuze, nangona belimele, bangabinxibelelani nabanye.

Indlela yokutshintsha ukusuka kwelinye ivolthi ukuya kwelinye kukudlala ngenani lokujika okanye ukujika kwentambo yobhedu kumjikelo wokuqala kunye nowesibini. Ngokutsho Umthetho kaLenz, okwangoku kufuneka itshintshane ukuze oku kwenzeke ngokungafaniyo kwenzeke, ke isiguquli asinakho ukusebenza ngokuthe ngqo yangoku.

Njengoko ubona kumfanekiso ongentla, ubudlelwane Phakathi kweekhoyili i-voltage kunye nokuqina kulula kakhulu. Apho i-N linani lokujika kwe-winding (P = ephambili, S = yesibini), ngelixa i-V ngumbane (P = usetyenziswa kwiprayimari, S = ukuphuma kwesekondari), okanye ndilingana ngoku ...

por umzekelo, Khawufane ucinge ukuba unesiguquli esinama-200 omoya omoya kwiziprayimari nakwi-100 yomoya kwisekondari. Umbane wokufaka we-200v usetyenziswa kuyo. Nguwuphi umbane oza kuvela kwimveliso yesibini? Ilula kakhulu:

200/100 = 220 / V

2 = 220 / v

v = 220/2

v = 110v

Oko kukuthi, iyakuguqula igalelo le-220v libe yi-110v kwimveliso yalo. Kodwa ukuba inani lokujika libuyisiwe kumjiko wokuqala kunye nowesibini, ukubuyela umva kuya kwenzeka. Umzekelo, khawufane ucinge ukuba i-voltage eyi-220v esisiseko isetyenziswa kwiziprayimari, kodwa ezona zineendawo ezi-100 ezijikayo kwaye ezesibini zinamacala angama-200. Kwi utyalomali oku:

100/200 = 220 / V

0.5 = 220 / v

v = 220/0.5

v = 440v

Njengoko ubona, kule meko ombane iphindwe kabini ...

## Yintoni isiGuquli seToroidal?

Yonke into etshintshelwe kwisiguquli esiqhelekileyo iyasebenza nakwifayile ye- toroidal inguqu, nangona le inezinto ezahlukeneyo, kunye nezinye izibonelelo. Kodwa umgaqo wokusebenza kunye nokubala kunokukunceda uqonde ukuba isebenza njani.

Kwijiyometri, i-torid bubuso bohlaziyo obuveliswe yipoligoni okanye umjikelo ovaliweyo wenqwelomoya ojikeleza ujikeleze umgca wangaphandle we-coplanar ongahambelaniyo nawo. Oko kukuthi, ngamagama alula, luhlobo lweringi, idonati, okanye i-hula hoop.

Isiguquli se-toroidal siqinisekisa ukubhobhoza okuphantsi, kunye nelahleko ngenxa amaza amancinci eddy kunokuba kwisiguquli esiqhelekileyo. Ke baya kufudumeza kancinci kwaye basebenze ngakumbi, kunye nokuqina ngakumbi ngenxa yemilo yabo.

Njengabaguquli abaqhelekileyo, banokuba nazo ngaphezulu kwee-windings ezimbini, oko kungakhokelela kwikhoyili efanayo yegalelo, kunye nekhoyili ezininzi zokuphuma, nganye inokuthi iguqulwe ibe ngumbane owahlukileyo. Umzekelo, cinga ukuba zimbini, enye isuka kwi-220v iye kwi-110v kwaye enye isuka kwi-220v iye kwi-60v, eluncedo kakhulu kulawo mabanezamandla apho kufuneka khona imibane eyahlukeneyo.

Kule meko, endaweni yokuvelisa amandla kazibuthe Ngaphakathi kumbindi wentsimbi emile okwesikwere, iisangqa ezixineneyo ziveliswa kwi-torus. Ngaphandle kwayo intsimi iyakuba zero, ukomelela kweli candelo kuya kuxhomekeka kwinani lokujika.

Enye into ekhethekileyo kukuba intsimi ayifani, yomelele kufutshane nomsesane kwaye ibuthathaka ngaphandle. Oko kuthetha ukuba intsimi iya kuncipha njengoko irediyo ikhula.

Ulwalamano lwe amandla igalelo kunye nemveliso iyahluka ngokuxhomekeka kubungakanani kunye neemeko zokusebenza, kodwa phantse zihlala ziba phezulu kunezo ziguquli eziqhelekileyo. Ukongeza, ekubeni ilahleko ezichasayo zesiguquli zivela kwicingo lobhedu lwekhoyili kunye nelahleko engundoqo, kwaye kuba i-toroid inelahleko ezimbalwa, iya kusebenza ngakumbi njengoko bendikhe ndatsho ngaphambili.

### Izicelo

Las usetyenziso okanye usetyenziso ziyafana nezo ziguquli eziqhelekileyo. Isiguquli se-toroidal sihlala sisetyenziswa ngakumbi kwicandelo lonxibelelwano, izixhobo zomculo, izixhobo zonyango, izikhulisi, njl.

### Izinto eziluncedo nezingalunganga

Njengamaxesha onke, isiguquli se-toroidal sinezibonelelo zako, kodwa kukwakho nezinye iingxaki. Phakathi iingenelo ukuma:

• Zisebenza kakuhle ngakumbi.
• Kwi-inductance efanayo ne-solenoid yesiqhelo, i-toroid iya kufuna ukujika okumbalwa, ngenxa yoko icwecwe ngakumbi.
• Ngokuvalelwa kumazibuthe ngaphakathi kubo, banokubekwa kufutshane nezinye izinto zombane ngaphandle kokuphazamiseka kwizinto ezingafunekiyo.

Phakathi ngxaki Zizo:

• Ziyinkimbinkimbi ngakumbi kumoya kunezinto eziqhelekileyo.
• Kunzima ngakumbi ukungena.

## Apho uthenga i-toroidal transformer

Ungabafumana phantse naphi na Ivenkile yekhompyutha ezizodwa, okanye unokufumana enye kwiAmazon. Umzekelo, Nazi ezinye iingcebiso:

Njengoko sele ubonile, bahlukile VA, 100VA, 300VA, njl Eli xabiso libhekisa kumthwalo omkhulu ovumelekileyo. Kwaye kulinganiswa ngee-volts nge-ampere nganye.
