ari shanduri (senge toroidal transformer) ari zvikamu zvinowanzoshandiswa mumidziyo yakawanda. Kunyanya mune ayo anoshandisa DC, sezvo ivo vachibvumidza kuenda kubva kumatunhu akakwirira emagetsi network kune aya madhivhiti akabatanidzwa kune akadzika ma voltages kwaanowanzo shanda (12v, 5v, 3.3v ...) uyezve shanduka kubva ku AC kuCC uchishandisa ese mamwe matanho e magetsi.
Kukosha kwayo kwakadai zvekuti iwe unofanirwa kuziva kuti inoshanda sei urwu rudzi rwemashanduko nemaapplication avo, uyezve kuti uye kupi uye kuti ungatenga sei chimwe chazvo kune ako mapurojekiti, nezvimwe. Kwese kusahadzika uku kuchagadziriswa neichi gwara ...
Chii chinonzi transformer?
Un Shanduri Icho chinhu chinobvumidza kupfuura kubva kune inochinjika magetsi emagetsi kuenda kune rakasiyana. Iyo inogona zvakare kushandura iyo yazvino kusimba. Chero nzira, inogara ichichengeta kuwanda kwesimba uye kukosha kwesimba kwakasimba. Ndokunge, isofrequency uye isopower ...
Iyi paramende yekupedzisira haina chokwadi, chingave chakanakira dzidziso, nekuti mukuita kune kurasikirwa nenzira yekupisa, Rimwe rematambudziko makuru ezvikamu izvi. Ndokusaka zvaenda kubva pakushandisa yakasimba ferrous cores kusvika pakuzvinamatira (silicon simbi machira ane kuputira pakati pavo) kudzikamisa eddy mafungu kana maparasiti mafungu.
Kuti ibudirire pachinangwa chayo, magetsi anopinda kuburikidza nekumhanyisa kwawo kwekumisikidza anoshandurwa kuita magineti nekuda kwekutenderera uye nesimbi musimboti. Ipapo, magineti ayo anoyerera nepakati pesimbi achakonzera simba razvino kana remagetsi mune yechipiri kutenderera kuti ipe iyo yazvino pakubuda kwayo. Ehezve, iyo inoitisa waya yeiyo yakakomberedzwa ine mhando yekudzivirira varnish kuitira kuti, kunyangwe ivo vakakuvara, varege kusangana neumwe neumwe.
Iyo nzira yekushandura kubva kune imwe voltage kuenda kune imwe kutamba nenhamba yekutendeuka kana kutendeuka kwetambo yemhangura mune yekutanga uye yechipiri ichitenderera. Maererano Mutemo waLenz, iyo yazvino inofanirwa kunge ichichinjisa kuti iyi flux kusiyanisa iitike, saka shanduko haigone kushanda neakananga ikozvino.
Sezvauri kuona mumufananidzo uri pamusoro, hukama Pakati pema coils iyo voltage uye iyo kusimba iri nyore kwazvo. Iko N ndiyo nhamba yekutendeuka kweiyo ichitenderera (P = yekutanga, S = yechipiri), nepo V iri voltage (P = yakashandiswa kune yekutanga, S = kubudiswa kwechipiri), kana ini ndakaenzana neyazvino ...
kubudikidza muenzaniso, Fungidzira kuti iwe une transformer ine mazana maviri mudenga mune yekutanga uye zana zana mudenga mune yechipiri. Magetsi ekupinza e200v anoiswa pairi. Ndeapi magetsi anozoonekwa pakubuda kwechipiri? Zvakareruka:
200/100 = 220 / V
2 = 220 / v
v = 220/2
v = 110v
Ndokureva, ichave yakashandura iyo 220v yekuisa kuita 110v pakubuda kwayo. Asi kana iyo nhamba yekutendeuka ikadzoserwa mukutanga uye sekondari kumhanyisa, zvinodzoka zvaizoitika. Semuenzaniso, fungidzira kuti iwo iwo 220v ekutanga magetsi anoshandiswa kune epuraimari, asi yekutanga ine zana anotendeuka uye yechipiri ine mazana maviri anotendeuka. Ku invest izvi:
100/200 = 220 / V
0.5 = 220 / v
v = 220/0.5
v = 440v
Sezvauri kuona, mune ino kesi iyo voltage yakapetwa ...
Chii chinonzi toroidal transformer?
Zvese zvataurwa kune zvakajairika shanduko zvinoshandawo kune iyo toroidal mushanduri, kunyangwe ichi chiine zvimwe zvakasiyana maficha, pamwe nezvimwe mabhenefiti. Asi musimboti unoshanda uye kuverenga kunogona kukubatsira kuti unzwisise kuti zvinoshanda sei.
Iyo toroidal transformer inovimbisa yakaderera leakage flux, pamwe nekurasikirwa nekuda kwe madiki eddy mafungu kupfuura mune yakajairika shanduko. Saka vanozopisa zvishoma uye vanyatsoita basa, pamwe nekuve vakanyanya kuumbana nekuda kwechimiro chavo.
Kufanana neakajairika shanduko, ivo vanogona zvakare kuve anopfuura maviri mavhiri, izvo zvinokonzeresa yakafanana coil yekuisa, uye akati wandei ekuburitsa makoiri, imwe neimwe inogona kunge ichichinjira kune rakasiyana voltage. Semuenzaniso, fungidzira pane maviri, imwe inoenda kubva pa220v kuenda ku110v uye imwe ichibva kubva ku220v kuenda ku60v, inova inoshanda kune iwo magetsi magetsi panodiwa ma voltages akati wandei.
Mune ino kesi, panzvimbo yekugadzira iyo magnetic field Mukati mekona-yakaita simbi musimboti, macircuit madenderedzwa anogadzirwa mune iyo torus. Kunze kwayo munda uchave zero, simba remunda uyu rinoenderanawo nenhamba yekutendeuka.
Chimwe chinoshamisa ndechekuti munda haina yunifomu, rakasimba kupfuura mukati memhete uye risina simba kunze. Izvi zvinoreva kuti munda uchaderera sezvo nharaunda ichikura.
Hukama hwe simba kuisa uye kuburitsa kunosiyana zvichienderana nesaizi nemamiriro ekushanda, asi kazhinji nguva dzose zvinowanzove zvakakwirira pane izvo zveanowanzo shanduka. Zvakare, sezvo izvo zvinopesana nekurasikirwa kweshanduki kunouya kubva kune yemhangura waya yemakoroni uye nekurasikirwa kwepakati, uye sezvo toroid iine zvishoma kurasikirwa, ichave inoshanda zvakanyanya sezvandakamboreva kare.
Applications
ari kunyorera kana kushandisa iwo akafanana neaya eanowanzo shanduka. Iyo toroidal transformer inowanzo shandiswa zvakanyanya muchikamu cheterevhizheni, zviridzwa, zvigadzirwa zvekurapa, zvinowedzera.
Kubatsira uye kusagadzikana
Sezvo zvinowanzoitika, iyo toroidal transformer ine zvayakanakira, asi kune zvekare zvimwe zvinokanganisa. Pakati zvakanakira taura:
- Ivo vanoshanda zvakanyanya.
- Kune imwechete inductance seyakajairwa solenoid, iyo toroid inoda mashoma kutendeuka, saka iri yakawanda compact.
- Nekuita iyo magineti yakavharirwa mukati mavo, vanogona kuiswa padhuze nemimwe michina yemagetsi pasina kupindira kubva kune zvisingadiwe inductances.
Pakati pe kukanganisa Ndizvo:
- Izvo zvakanyanya kuomesa kumhepo pane zvakajairika.
- Izvo zvakare zvakanyanya kuomesa kugadzirisa mukati.
Kwokutenga toroidal transformer
Unogona kuvawana kunenge chero kupi chitoro chemagetsi nyanzvi, kana iwe unogona zvakare kuwana imwe kubva kuAmazon. Semuenzaniso, heano mamwe mazano:
- Yakajairika shanduko 220v kusvika 24v.
- DollaTek 220v kusvika 24v (mbiri 12v, 12v)
- Sedlbauer kubva 230v kusvika 24V (mbiri 12v + 12v).
- Tector kubva 230v kusvika 12v
Sezvawaona, ivo vakasiyana VA, 100VA, 300VA, nezvimwe. Kukosha uku kunoreva iwo mwero unobvumidzwa wakanyanya. Uye inoyerwa mu volts pa ampere.
