Toroidal transformer: chilichonse chomwe muyenera kudziwa

toroidal chosinthira

ndi osintha (monga toroidal transformer) ali zigawo chimagwiritsidwa ntchito pazida zambiri. Makamaka omwe amagwiritsa ntchito DC, popeza amalola kuti achoke pamiyeso yamagetsi yamagetsi yomwe zida izi zimalumikizidwa ndi zotsika zomwe nthawi zambiri zimagwira (12v, 5v, 3.3v ...) ndikusintha kuchokera ku AC ku CC pogwiritsa ntchito magawo ena onse a magetsi.

Kufunika kwake ndikuti muyenera kudziwa momwe zimagwirira ntchito zosinthira zamtunduwu ndi momwe amagwiritsira ntchito, komanso komwe mungagule chimodzi mwazomwe mungagwiritse ntchito, ndi zina zambiri. Zikaiko zonsezi zidzathetsedwa ndi bukhuli ...

Kodi thiransifoma ndi chiyani?

chithunzi chosinthira

Un chosinthira Ndi chinthu chomwe chimalola kudutsa pamagetsi amagetsi aposachedwa kupita kwina. Ikhoza kusintha kusintha kwamakono. Mulimonse momwe zingakhalire, nthawi zonse zimasunga mayendedwe azizindikiro ndi mphamvu zamagetsi mosadukiza. Ndiye kuti, kufupika kwanthawi yayitali komanso mphamvu ...

Chotsatira chomalizachi sichiri chowonadi, chikadakhala chosinthira choyenera, chifukwa pakuchita kulipo zotayika ngati kutentha, Limodzi mwa mavuto akulu kwambiri pazigawozi. Ichi ndichifukwa chake adasiya kugwiritsa ntchito makina olimba kuti awapake (ma sheet achitsulo a silicon okhala ndi kutchinjiriza pakati pawo) kuti achepetse mafunde akuthwa kapena ma parasitic.

Kuti akwaniritse cholinga chake, magetsi omwe amalowa kudzera pakupindika kwake amasinthidwa kukhala nyese chifukwa cha kumulowetsa ndi pachimake chachitsulo. Kenako, kukoka komwe kumadutsa pachitsulo kumapangitsa kuti pakhale mphamvu yamagetsi yamagetsi yamagetsi pakapangidwe kake kuti ipereke zomwe zatchulidwazi. Zachidziwikire, waya woyendetsa wa windings ali ndi mtundu wa varnish wokutira kuti, ngakhale atavulazidwa, asalumikizane.

Njira yosinthira kuchoka pamagetsi amtundu wina kupita kwina ndikusewera ndi kuchuluka kwa kusinthana kapena kusinthana kwa waya wamkuwa poyambira koyambirira komanso kwachiwiri. Malinga ndi Lamulo la Lenz, pakadali pano pakuyenera kusinthasintha kuti kusinthaku kuchitike, chifukwa chake chosinthira sichingagwire ntchito pakadali pano.

Monga mukuwonera pachithunzichi pamwambapa, ubale Pakati pazitsulo zamagetsi ndi mphamvu ndizosavuta. Komwe N kuli kosinthana kwakanthawi kokhotakhota (P = pulayimale, S = sekondale), pomwe V ndiye magetsi (P = amagwiritsidwa ntchito koyambirira, S = kutulutsa kuchokera kusekondale), kapena ndili wofanana ndi wapano ...

Por Mwachitsanzo, Ingoganizirani kuti muli ndi thiransifoma yokhala ndi makina ozungulira 200 kupulayimale ndipo 100 mwauzimu mwa sekondale. Mphamvu yamagetsi yama 200v imagwiritsidwa ntchito pamenepo. Ndi magetsi ati omwe adzawonekere potulutsa sekondale? Zosavuta kwambiri:

200/100 = 220 / V

2 = 220 / v

v = 220/2

v = 110v

Izi zikutanthauza kuti, idasintha ma 220v kukhala 110v pazotulutsa zake. Koma ngati kuchuluka kosinthana kumasinthidwa koyambira ndi sekondale, kusinthaku kumachitika. Mwachitsanzo, tangoganizirani kuti mphamvu yamagetsi yoyambira 220v imagwiritsidwa ntchito koyambirira, koma yoyamba imakhala ndi kutembenuka 100 ndipo yachiwiri ili ndi kutembenukira 200. Kwa sungani ndalama izi:

100/200 = 220 / V

0.5 = 220 / v

v = 220/0.5

v = 440v

Monga mukuwonera, pakadali pano magetsi awonjezeredwa ...

Kodi chosinthira toroidal ndi chiyani?

Chithunzi chosinthira toroidal

Chilichonse chomwe chanenedwa chosinthira wamba chimagwiranso ntchito pa toroidal chosinthira, ngakhale ili ndi zina, komanso maubwino ena. Koma mfundo yogwirira ntchito komanso kuwerengera kungakuthandizeni kumvetsetsa momwe zimagwirira ntchito.

Mu geometry, torid ndi mawonekedwe osintha omwe amapangidwa ndi polygon kapena yokhotakhota yokhotakhota yomwe imazungulira mozungulira mzere wakunja wa coplanar womwe sudutsana nawo. Ndiye kuti, m'mawu osavuta, ndi mtundu wa mphete, donut, kapena hula hoop.

Kusintha kwa toroidal kumatsimikizira kutuluka kwakanthawi kochepa, komanso zotayika chifukwa cha ma eddy ang'onoang'ono kuposa chosinthira wamba. Chifukwa chake amatenthetsa pang'ono ndikukhala ogwira ntchito bwino, komanso kukhala ophatikizika chifukwa cha mawonekedwe awo.

Monga ma transformer wamba, amathanso kukhala nawo zopitilira ziwiri, zomwe zingapangitse coil yofananira imodzimodzi, ndi ma coil angapo otulutsira, iliyonse imatha kusintha magetsi ena. Mwachitsanzo, tangoganizirani pali ziwiri, imodzi yomwe imachokera ku 220v kupita ku 110v ndipo imodzi imachokera ku 220v mpaka 60v, zomwe ndizothandiza kwambiri pamagetsi omwe pamafunika ma voltions angapo.

Poterepa, m'malo mopanga fayilo ya maginito Mkati mwazitsulo zazitsulo zooneka ngati ma square, timizere tomwe timapangidwa timakhala mkati mwa torus. Kunja kwake mundawo ukhala zero, kulimba kwa mundawu kudzadaliranso kuchuluka kwa mayendedwe.

Chinthu china chodziwika ndi chakuti munda si yunifolomu, Ndiwolimba kwambiri pafupi ndi mkatikati mwa mphete komanso panja pofooka. Izi zikutanthauza kuti mundawo ucheperako pamene utali wozungulira ukukulira.

Ubale wa mphamvu zolowetsa ndi zotuluka ndizosiyanasiyana kutengera kukula ndi magwiridwe antchito, koma pafupifupi nthawi zonse amakhala okwera kuposa omwe amasinthira wamba. Kuphatikiza apo, popeza zotayika zotsutsana ndi thiransifoma zimachokera ku waya wamkuwa wama coil ndi zotayika pachimake, ndipo popeza toroid ili ndi zotayika zochepa, zizigwira ntchito bwino monga ndidanenera kale.

ofunsira

ndi ntchito kapena ntchito ali ofanana ndi omwe amasintha nthawi zambiri. Toroidal transformer imagwiritsidwa ntchito kwambiri pagawo lama telefoni, zida zoimbira, zida zamankhwala, zokulitsira, ndi zina zambiri.

Ubwino ndi zoyipa

Monga momwe zimakhalira nthawi zonse, chosinthira toroidal chimakhala ndi maubwino ake, koma palinso zovuta zina. Pakati pa ubwino tulukani:

  • Zimakhala zosavuta.
  • Pakulowereranso kofanana ndi solenoid yokhazikika, toroid imafunikira kutembenuka kocheperako, chifukwa chake imakhala yolumikizana.
  • Mwa kukhala ndi mphamvu yamaginito mkati mwawo, amatha kuyikidwa pafupi ndi zida zina zamagetsi popanda kusokonezedwa ndi ma inductors osafunikira.

Pakati pa zovuta Iwo ndi:

  • Zimavuta kwambiri kupitilira kuposa zachilendo.
  • Zimakhalanso zovuta kukambirana.

Komwe mungagule chosinthira cha toroidal

Mutha kuwapeza pafupifupi kulikonse shopu yamagetsi apadera, kapena mutha kupezanso imodzi kuchokera ku Amazon. Mwachitsanzo, nazi malangizo:

Monga momwe mwaonera, ndi osiyana VA, 100VA, 300VA, ndi zina. Mtengo uwu umatanthauza katundu wololedwa wokwanira. Ndipo imayesedwa mu volts pa ampere.


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
