Kutsika kwamasintha 220 mpaka 36 volts

Zosintha 220 mpaka 36 volts ndizofunikira kuyendetsa dera loyatsa magetsi m'madzi osambira, saunas, mabafa, malo osungira. Zofuna zachitetezo zimapangitsa kuti ena aziletsa kugwiritsa ntchito mpweya wozungulira wa 220 volts m'chipinda chokhala ndi chinyezi. Choncho, njira yabwino yothetsera vutoli ndi kugwiritsa ntchito njira zotsatila za 12, 24 kapena 36 volts. Ngati pali munthu wothandizana ndi magetsi, amamva kuti akungowonongeka. Sichidzavulaza thupi la munthu.

Zomangamanga

Mofanana ndi zina zilizonse, transformer yowonongeka kuchokera ku 220 mpaka 36 volts ili ndi zigawo zikuluzikulu zitatu:

1. Kuthamanga kwakukulu.
2. Kupuma kwapakati.
3. Makina opanga maginito.

Zilizonse zoyambira ndi zakumwera zimakhala ndi maulendo ena a zitsulo zamkuwa. Kawirikawiri, waya wamkuwa amagwiritsidwa ntchito poika zida, chifukwa zimakhala bwino kwambiri kuposa zida zowonongeka. Ngati mumagwiritsa ntchito aluminium, idzafunikanso zambiri, zomwe zimachulukitsa kukula kwa transformer. Zoona, mawaya aluminiyumu mu kutsekemera kwa lacquer ankagwiritsidwa ntchito mu magetsi otetezera. Maginito amatha kupanga zonse kuchokera ku transformer steel ndi kuchokera ku ferromagnet. Zinthuzi ndi zabwino kuposa zitsulo.

Chiŵerengero cha mphamvu ndi kusintha

Mukhoza kuwonetsetsa ngakhale kuyesa mphamvu ya mtundu uliwonse wa transformer - zazikuluzikuluzikulu, ndizozitali. Koma kuti mumvetsetse bwino mphamvu ndizofunikira kugwiritsa ntchito machitidwe apadera. Njira yosavuta yowerengera mphamvu ya transformer ndi kuchulukitsa magetsi a mphepo yowonjezera ndi yomwe ili mkati mwake. Pezani mphamvu yamtengo wapatali ya transformer mukufufuza. Kuti mugwire ntchito pa chilengedwe ndi mawonekedwe a chipangizo choterocho, mufunikira kudziwa chinthu china chomwe chimapanga transformer.

Izi sizingowonjezera coefficient of transformation. Ndilo chiŵerengero cha chiwerengero cha kutembenukira kwa chimphepo chachiwiri mpaka kumapeto koyambirira. Mtengo womwewo ukhoza kupezeka pogawa I2 / I1, komanso magetsi U2 / U1. Mmodzi mwazifukwa zitatuzi, mutenga mtengo womwewo. Mungawusowe powerengera nambala yeniyeni ya kutembenukira kwa mphepo zoyamba ndi zam'mbali.

Kuwerengedwa kwa transformer

Ngati kuli kofunikira kupanga mapuloteni 220 mpaka 36 (1000 watts), ndizofunikira kugwiritsa ntchito ndondomeko yowerengera mphamvu pamapeto. Zatchulidwa pamwambapa, mphamvu ndi zofanana ndi zomwe zilipo pakali pano mpaka magetsi. Pankhaniyi, pali magawo awiri omwe amadziwika kuti ndi amphamvu: P2 mphamvu (1000 W) ndi magetsi ku gawo lachiwiri la U2 (36 V). Kuchokera muzondomekoyi tsopano ndi kofunika kuwerengera zamakono zomwe zimadutsa kudera lalikulu.

Chimodzi mwa magawo ofunikira ndizochita bwino, zomwe muwasintha siziposa 0.8. Zimasonyeza kuti mphamvu zomwe zimagwiritsidwa ntchito mwachindunji kuchokera ku intaneti zimalowa mu katundu wokhudzana ndi chiwongolero chachiwiri (pakali pano ndi 80% okha). Kusiyana kwa mphamvu kumawotcha maginito oyendayenda ndi mphepo. Icho chatayika, ndipo chosasinthika. Mphamvu yomwe imachotsedwa ku intaneti ya AC ikufanana ndi chiŵerengero cha P2 kufika pazochita.

Kusintha maginito mzere

Mphamvu zonse zimachotsedwa kuchokera kumayendedwe oyamba kupita ku chimphona chachiwiri kudzera mu maginito, omwe amapangidwa pachimake (pachimake). Amachokera ku mphamvu P1 yomwe gawo lachigawo cha S likudalira. Nthawi zambiri, mbale ya mawonekedwe a kalata "SH" imagwiritsidwa ntchito pachimake. Pachifukwa ichi, malo amtunduwu ndi ofanana ndi chida cha P1 ndi chinthu cha 1.2. Podziwa kufunika kwa dera, mutha kudziwa momwe angapititsire W ndi 1 V. Kuti muchite izi, mukufunikira 50 kugawidwa ndi dera.

Kuwombera m'mayendedwe oyambirira ndi apamwamba akudziwika - ndi 220 ndi 36 volts. Chiwerengero cha kutembenukira kwa mphepo iliyonse imatsimikiziridwa ndi kuchulukitsa magetsi ndi W. Zikakhala kuti decimal imakhala ikupezeka, nkofunika kuti muwazungulire. Tiyeneranso kukumbukira kuti pamene katundu wa secondary secondary akugwirizanitsa, kugwa kwa mpweya kumachitika . Pachifukwa ichi, ndi zofunika kuonjezera chiwerengero chakutembenukira pafupifupi 10% mwa chiwerengero chimodzi.

Mawindo oyenda

Ndipo tsopano tifunika kuwerengera zamakono zomwe zimayambira pampando wachiwiri ndi wachiwiri. Zamakono zili zofanana ndi chiŵerengero cha mphamvu ku magetsi. Ngati transformer 220 imapangidwa pa 36 volts (500 Watts), ndiye yamakono ofanana ndi chiŵerengero cha 500/36 = 13.89 A idzatuluka mu gawo lachiwiri. Mphamvu mu dera loyamba lidzakhala 625 W, ndipo mphamvuyi ndi 17.36 A.

Kenaka, kuwerengeka kwamakono kukuwerengedwa. Parameter iyi imatanthawuza mtengo wamakono wamakilomita angapo ofiira a waya pamtunda. Kawirikawiri, otembenuza amatenga kuchulukitsidwa kwamakono kwa 2 A / sq. Mm. Dera la waya lofunika kuti lipulumuke likhoza kudziwika ndi njira yowonongeka: zotsatirazi zimachulukitsidwa ndi mizere yambiri ya zamakono. Choncho, mu dera lachiwiri ndilofunika kugwiritsa ntchito waya omwe m'mimba mwake adzakhala ofanana ndi 0.8 mpaka 3.73, omwe ndi 2.9 mm (okwana 3 mm). Pakutha koyambirira, waya wokhala ndi mamita 3.33 mm ayenera kugwiritsidwa ntchito. Mukakhala kuti mulibe mawaya okhala ndi mphamvu yoyenera, mungagwiritse ntchito njira yosavuta. Mphepo ya waya panthawi imodzi ndi mawaya angapo ogwirizana. Pachifukwa ichi, chiwerengero cha zigawo za mtanda sizingakhale zocheperapo ndi zomwe munawerengedwa ndi inu. Chigawo cha waya chikufanana ndi chiŵerengero cha momwe mungagwiritsire ntchito.

Kutsiliza

Podziwa mayina onse osavutawa, mukhoza kupanga mwachindunji transformer yodalirika yomwe ingagwire ntchito mwangwiro. Koma inu mukufunikirabe kudziwa momwe mungagwirizanitse transformer 220 mpaka 36 volts. Mu ichi palibe chovuta, ndikwanira kugwirizanitsa zoyambira ndi AC 220 V network, ndi yachiwiri limodzi ndi katundu, kuyatsa magetsi, mwachitsanzo. Kuyambira nthawi yoyamba, yesetsani kulumikizana ndi transformer ndi mphamvu yochuluka ya mphamvu kuti mudziwe ngati maziko ndi zowonjezera zimatha.
