Single-phase transformer. Cholinga, chipangizo ndi zikuluzikulu

Pali nthabwala yakale ya koleji. Pa funso la mphunzitsi "kodi pulogalamu yamagulu imodzi" wophunzira amavomereza bwanji "Uh-uh!". Kumveka kumeneku kumachitikadi, chifukwa chakuti pamene malo opangira tizilombo toyambitsa matenda aphatikizidwa, timayambitsa maginito imayambitsa zomwe zimachititsa kuti maginito amtunda asunthike.

Pulojekiti imodzi yokha imapangidwa kuti ipange mphamvu yowonjezera ya kukula kwake kwa katundu umene sichifuna mphamvu ya magawo atatu.

Wotembenuza aliyense ali ndi mfundo ziwiri zazikuluzikulu: zamkati ndi zithupsa, pali awiri mwa iwo. Mfundo yogwira ntchito ndi yosavuta. Chifukwa cha njira yamagetsi kupyolera mwa woyendetsa pamtsinje waukulu, mphamvu ya electromotive (EMF) imapangidwira pamapeto . Mutuwu uli ndi mbale za ferromagnet, ndiko kuti, zinthu zomwe zimalimbikitsa kukweza maginito (magetsi a magetsi).

Ukulu wa emf umatsimikiziridwa ndi ndondomekoyi:

E = 4.44 x F x f x ω

Kumeneko:

"Ndi kukula kwake kwa maginito;

F ndifupipafupi zamakono;

Ω ndi chiwerengero chakutembenukira.

Mphamvu yovomerezeka yomwe gawo limodzi lamasinthidwe "lidzakokera" limatsimikiziridwa ndi gawo la waya limene makompyuta amalipiritsa ndi mphamvu ya maginito, makamaka maginito operekera mphamvu ya ferromagnet μ. Miyeso ya pachimake ndi chiwerengero cha kutembenuka ndi nkhani ya kuwerengera, yomwe nthawi zambiri imakhala yeniyeni ntchito mu masunivesite apamwamba.

Mulimonsemo, mphamvu zowonjezera zowonjezera zowonjezera, zowonjezereka kwambiri. Pazochitika zawo, kawirikawiri pali chilembo chokhala ndi mndandanda wa zigawo zazikulu (zovomerezeka zowonjezera zomwe zimaloledwa komanso zotulukapo). Komabe, izi sizichitika nthawi zonse.

Mwachizoloŵezi, okonzanso ambiri nthawi zambiri amakumana ndi chofunikira chotsitsirako kutentha kwapakati imodzi ya voltage transformer. Pofuna kutsimikizira kuti ndi koyenera, m'pofunikira kuti muphunzire makhalidwe a chipangizo chofunikiramo m'malo.

Chinthu choyamba choyenera kuchita ndicho kudziwa kulowera. Pankhani ya otsika otsika pansi, amatsutsa kwambiri.

Kenaka, mukuchidula mu intaneti, mukhoza kuyesa kuchuluka kwa magetsi mu idling mode. Chiŵerengero chazolowera ndi zotsatira za EMF ndi coefficient of transformation K. Chimodzimodzinso ndi chidutswa N mu / N kunja, ndiko, chiwerengero cha kutembenuka mu windings.

Pambuyo pake, mukhoza kugwirizanitsa kutsutsana kwakukulu (rheostat) monga katundu ndikuchotsani zamakono zamtunduwu pozindikira kufunika kwa zomwe zilipo panopa. Pamene katunduyo akuwonjezeka, magetsi amatha kuchepa.

Otembenuza si mphamvu yokha, komanso kuyesa. Pa nthawi yomwe kuli kofunikira kudziŵa kuchuluka kwa zomwe zikuchitika m'deralo, ammeter amagwiritsidwa ntchito. Zimapitilira mndandanda, ndipo ziyenera kukhala ndizitsulo zochepa kuphatikizapo chigawo chachikulu cha waya mu magnetic deflection system. Chipangizo choterocho chikanakhala chachikulu kwambiri komanso chokwera mtengo, osasuntha omwe amatha kusinthana ndi zinthu zomwe zimakhala zochepa komanso kuzidyetsa ku maselo amtundu wambiri. Sungani malonda sivuta, amangokhala kuti agwiritse ntchito owonjezera omwe akuwonetsedwa pazochitikazo.
