I-Los abaguquli (njenge-transformer ye-toroidal) kukhona izingxenye esetshenziswa kabanzi kumadivayisi amaningi. Ikakhulukazi kulabo abasebenzisa i-DC, ngoba bavumela ukusuka kumanani aphezulu wenethiwekhi kagesi lawa madivayisi axhunywe kumanani aphansi lapho ejwayele ukusebenza khona (12v, 5v, 3.3v ...) bese eguquka esuka ku-AC ku-CC usebenzisa ezinye izigaba ze- amandla kagesi.
Ukubaluleka kwayo kunjalo ukuthi kufanele wazi ukuthi isebenza kanjani lolu hlobo lwama-transformer nezicelo zalo, nokuthi ungathenga kuphi futhi kanjani eyodwa kumaphrojekthi akho, njll. Konke lokho kungabaza kuzoxazululwa ngalo mhlahlandlela ...
Yini i-transformer?
Un isiguquli Kuyinto evumela ukuthi kudlule kusuka kumbane oshintshashintshayo wamanje uye kokuhlukile. Ingaguqula futhi namandla wamanje. Kunoma ikuphi, kuzohlala kugcina imvamisa yesiginali namanani wamandla aqinile. Lokho wukuthi, ukujwayeleka nokuqina kwamandla ...
Le pharamitha yokugcina ayinalo iqiniso, kungaba ku-transformer ekahle yethiyori, ngoba empeleni kukhona ukulahlekelwa ngendlela yokushisa, enye yezinkinga ezinkulu zalezi zingxenye. Kungakho isukile ekusebenziseni izinsimbi eziqinile zensimbi ukuzinamathisela (amashidi wensimbi wensimbi ane-insulation phakathi kwawo) ukunciphisa imisinga ye-eddy noma imisinga ye-parasitic.
Ukufeza inhloso yayo, ugesi ongena ngokungena kwawo kokungenayo uguqulwa ube uzibuthe ngenxa emazombezombe nengaphakathi lensimbi. Ngemuva kwalokho, uzibuthe ogeleza phakathi komgogodla wensimbi uzokwenza amandla wamanje noma kagesi ku-elekthronikhi yesibili ukuthi anikeze okwamanje okukhishwayo. Vele, ucingo oluqhubayo lwe-windings lunohlobo oluthile lokuvikela i-varnish ukuze, yize belimele, bangaxhumani.
Indlela yokukwazi ukuguqula isuke komunye ugesi iye komunye ukudlala ngenani lokujika noma ukuphenduka kocingo lwethusi kukoyilo oluyinhloko nolwesibili. Ngokusho Umthetho kaLenz, i-current kufanele ishintshane ukuze lokhu kuhlukahluka kwe-flux kwenzeke, ngakho-ke isiguquli asikwazi ukusebenza nge-current current.
Njengoba ukwazi ukubona esithombeni ngenhla, ubuhlobo Phakathi kwamakhoyili i-voltage namandla kungelula. Lapho i-N inamba yokuphenduka kwe-winding (P = eyinhloko, i-S = yesibili), kuyilapho i-V i-voltage (P = isetshenziselwa okuyinhloko, i-S = ukuphuma kwesibili), noma ngilingana nokwamanje ...
Por isibonelo, Cabanga ukuthi une-transformer enemiklamo engu-200 komoya oyinhloko kanye nemiklamo engu-100 yesibili. I-voltage yokufaka engu-200v isetshenziswa kuyo. Yimuphi ugesi ozovela ekukhishweni kwesekondari? Kulula kakhulu:
200/100 = 220 / V
2 = 220 / v
v = 220/2
v = 110v
Lokho kusho ukuthi, kuzobe sekuguqule okokufaka okungu-220v kwaba ngu-110v ekuphumeni kwayo. Kepha uma inani lamaphenduka libuyiselwa emuva emazombezombe nasesekondari, okuphambene nalokho kungenzeka. Isibonelo, ake ucabange ukuthi i-voltage efanayo eyi-220v isetshenziswa kweyokuqala, kepha eyokuqala inezikhathi eziyi-100 bese kuthi eyesibili ibe nokujika okungama-200. Ku izimali lokhu:
100/200 = 220 / V
0.5 = 220 / v
v = 220/0.5
v = 440v
Njengoba ukwazi ukubona, kulokhu i-voltage iphindwe kabili ...
Yini i-transformer ye-toroidal?
Konke okushiwo i-transformer ejwayelekile kuyasebenza nakwi i-toroidal transformer, yize lokhu kunezici ezahlukile, kanye nezinzuzo ezithile. Kepha umgomo wokusebenza kanye nezibalo kungakusiza uqonde ukuthi kusebenza kanjani.
Isiguquli se-toroidal siqinisekisa ukugeleza okuphansi kokuvuza, kanye nokulahleka ngenxa ye- amancane eddy currents kune-transformer ejwayelekile. Ngakho-ke zizofudumeza kancane futhi zisebenze ngokwengeziwe, futhi zisebenze kahle ngenxa yokuma kwazo.
Njengabaguquli abavamile, bangaba nakho ama-windings angaphezu kwamabili, lokho kungaholela kukhoyili efanayo yokufaka, kanye namakhoyili amaningi wokukhipha, ngalinye lingaguqulela kumbane ohlukile. Isibonelo, cabanga ukuthi kunezimbili, esisodwa esisuka ku-220v siye ku-110v nesinye esisuka ku-220v siye ku-60v, okusebenziseka kakhulu kulezo zinto ezinikezwa ugesi lapho kudingeka khona imithamo ehlukahlukene.
Kulokhu, esikhundleni sokwenza i- amandla kazibuthe Ngaphakathi kwengqimba yensimbi emise okwesikwele, imibuthano egxilile ikhiqizwa ku-torus. Ngaphandle kwayo inkambu izoba uziro, amandla ale nkambu azoncika kwinani lamaphuzu.
Okunye okuhlukile ukuthi insimu akufani, iqine eduze kwengaphakathi lendandatho futhi ibuthakathaka ngaphandle. Lokho kusho ukuthi inkambu izokwehla njengoba indawo ikhula.
Ubuhlobo be amandla okokufaka nokukhiphayo kuyahlukahluka kuye ngosayizi nezimo zokusebenza, kepha cishe ngaso sonke isikhathi kuthambekele ekubeni phezulu kunaleso soguquli abajwayelekile. Ngaphezu kwalokho, njengoba ukulahleka okuphikisayo kwe-transformer kuvela ocingweni lwethusi lwamakhoyili nokulahleka kwengqikithi, futhi njengoba i-toroid inokulahleka okuncane, izosebenza kangcono njengoba bengivele ngivezile ngaphambili.
Aplicaciones
I-Las izinhlelo zokusebenza noma ukusetshenziswa ziyefana nezabaguquli abavamile. Isiguquli se-toroidal sivame ukusetshenziswa kakhulu emkhakheni wezokuxhumana ngocingo, izinsimbi zomculo, amadivayisi wezokwelapha, ama-amplifiers, njll.
Izinzuzo nokungalungi
Njengoba kuhlala kwenzeka, isiguquli se-toroidal sinezinzuzo zaso, kepha kukhona nokubi okuthile. Phakathi izinzuzo phuma:
- Zisebenza kahle kakhulu.
- Okwe-inductance efanayo ne-solenoid ejwayelekile, i-toroid izodinga ukujika okumbalwa, ngakho-ke icwecwe kakhudlwana.
- Ngokwenza ukuthi amandla kazibuthe avalelwe ngaphakathi kubo, angabekwa eduze kwezinye izinto ze-elekthronikhi ngaphandle kokuphazanyiswa yizimbangela ezingafuneki.
Phakathi kwe ukungalungi Yilezi:
- Ziyinkimbinkimbi kakhulu kunomoya kunalezo ezivamile.
- Kunzima futhi ukushuna.
Ungathenga kuphi i-toroidal transformer
Ungabathola cishe noma kuphi isitolo se-elekthronikhi ezikhethekile, noma ungathola futhi eyodwa kusuka e-Amazon. Isibonelo, nazi izincomo:
- I-transformer ejwayelekile 220v kuya ku-24v.
- I-DollaTek 220v kuye ku-24v (i-dualv, i-12v)
- ISedlbauer isuka ku-230v iye ku-24V (ngababili be-12v + 12v).
- Tector kusuka ku-230v kuya ku-12v
Njengoba ubonile, zihlukile VA, 100VA, 300VA, njll. Leli nani lisho umthwalo omkhulu ovunyelwe. Futhi kukalwa ngama-volts nge-ampere ngayinye.
