Poyang'anira ma transformer ku fakitale, ma magnetic cores ambiri a transformer amakhala ndi ma blocks osowa chifukwa cha kugwedezeka kwa ma bumps kapena kukanikiza kwa fixture. Kodi zotsatira za kugwa kwa transformer core ndi zotani? Nkhaniyi ikambirana zomwe zili mkati mwake.
Tikudziwa kuti mu ma transformer, ntchito yaikulu ya maginito core ndikupereka dera la maginito, zomwe zimathandiza kuti transformer izitha kusamutsa mphamvu bwino. Izi zitha kuwonetsedwanso bwino mu njira yowerengera ya inductance:
Kawirikawiri, timaona kuti mpweya umalowa m'malo mwake ngati 1, pomwe mphamvu ya maginito imatha kufika pa makumi, ndipo ambiri amatha kufika pa zikwi kapena ngakhale zikwi zambiri.
Poganizira izi, ma transformer okhala ndi maginito cores amawonjezera kwambiri mphamvu zawo, ndipo mphamvu zomwe zimasungidwa ndi kutumizidwa zimathanso kuwonjezeredwa moyenerera. Kugwira ntchito bwino kwa kutumiza kwawo kudzawongoleredwanso pamlingo winawake.
Kuphatikiza apo, pakati pa transformer pali chithandizo china cha kapangidwe kake pa chinthu chonse cha transformer, zomwe zimathandiza kusunga bata la transformer ndikuchepetsa phokoso ndi kugwedezeka.
Ngati pali chipika chosowa mu transformer core, izi zidzakhudza kufalikira kwabwinobwino kwa maginito circuit. Pambuyo poti maginito core asowa, gawo loyambirira la maginito core limakhala mpweya, zomwe zimapangitsa kuti maginito ayambe kukana, kuchepa kwa magwiridwe antchito, komanso pazochitika zazikulu, kuchepa kwa inductance, zomwe zimaika pachiwopsezo ntchito yabwinobwino ya makina onse.
Ma transformer ena alinso ndi ma cores a maginito omwe akusowa. Pakagwira ntchito kwa nthawi yayitali ya makina onse, ming'alu yaying'ono mkati mwa core ya maginito (gawo lomwe silinagwe kuchokera pa block) imafulumira ndikukulirakulira, zomwe zimapangitsa kuti kutayika kwakukulu ndi kutentha kwa transformer yonse kukwere, zomwe zimapangitsa kuti makina alephere kugwira ntchito.
Kuchokera pamalingaliro awa, kusowa kwa ma magnetic core blocks mu ma transformer sikuti kumakhudza magwiridwe antchito okha, komanso kumakhudza magwiridwe antchito ndi kudalirika kwa ma transformer. Pakadali pano, miyezo yowonekera ya ma magnetic core chips a opanga ambiri ndi awa: dera la chipping imodzi siliyenera kupitirira 3% ya malo onse a magnetic core, ndipo dera la chipping ziwiri kapena kuposerapo siliyenera kupitirira 5%.
Opanga ena alinso ndi kusiyana kwina, komwe sikudzafotokozedwa bwino pano. Chofunika kwambiri ndi kusiyana kwa malire a kapangidwe pakati pa opanga, zomwe zimapangitsa kuti pakhale miyezo yosiyana yowongolera.
Poyerekeza ndi miyezo, tikukhulupirira kuti chifukwa cha kugwa kwa pakati pa transformer ndichofunika kwambiri. Makamaka motsogozedwa ndi mphamvu zakunja, sikuti pamwamba pa pakati pa transformer pakhoza kugwa kokha, komanso kungayambitse ming'alu mkati mwa pakati pa transformer, ndipo chiopsezo sichingayesedwe kokha.
Pankhaniyi, kusweka kwa maginito pakati pa transformer ndikofunikira kwambiri kuti tiziganizira kwambiri.
