Ubushushu beCurie ye-transformer core

“Ngexesha elithile emva, umntu wabuza ukuba imagnethi inenqanaba lokumelana nobushushu. Kwaye umntu waphendula ngolu hlobo:

'Inqanaba lokumelana nobushushu lelezixhobo zokugquma. Undoqo wemagnethi awuthathwa njengesixhobo sokugquma, ngoko ke akanalo inqanaba lokumelana nobushushu. Kodwa ineparamitha enxulumene nobushushu ebizwa ngokuba yiUbushushu beCurie.'

Namhlanje, makhe sithethe malunga 'Ubushushu beCurie' ye-magnetic core.

Ubushushu beCurie, obukwabizwa ngokuba yiCurie point okanye indawo yemagnethi yotshintsho, kuxa amandla emagnethi ezinto ehla aye ku-0 njengoko ifudumala. Ifunyenwe yiCuries ngasekupheleni kwenkulungwane ye-19: xa ufudumeza imagnethi kubushushu obuthile, imagnethi yayo yasekuqaleni iyanyamalala.

Kwiziguquli (ii-inductors), ukuba iundoqo wemagnethi's ubushushu buhamba ngaphezu kobushushu bayo beCurie, bungenza ukuba inductance yehle ukuya ku 0. Ngelixa uninzi lweemveliso zinokuphinda zifumane umsebenzi wazo emva kokuphola phantsi, kubaguquli (inductors) ekusebenzeni, ukuba ne-zero inductance kuya kukhokelela kukusilela kunye nokudinwa.

Ngoko xa uyila kwaye ukhethaiinguqu(ii-inductors), kubalulekile ukushiya umda othile ukuze ugcine ubushushu bemagnethi bungaphantsi kwendawo yeCurie ngexesha lokusebenza.

Iqondo lobushushu leCurie lamandla emanganese-zinc ferrite lingaphezulu kwama-210°C. Uninzi lwezixhobo zokugquma i-transformer (inductor) zinamaqondo obushushu asezantsi kunale, ke ngexesha lokusebenza, undoqo wemagnethi awuzukufikelela kumaqondo obushushu anjalo.

Ubushushu beCurie be-high-conductivity manganese-zinc ferrite bungaphezulu kwe-110°C. Uninzi lwezixhobo zokugquma i-transformer (inductor) zinokubamba amaqondo obushushu aphezulu kunolu, kwaye ubushushu be-transformer (inductor) emva kokusebenza bunokuhamba ngokulula ngaphaya koku. Ke, ngenene kufuneka sinikele ingqalelo kwindlela esiyila ngayo ii-cores zemagnetic ezine-high-conductivity ukuqinisekisa ukuba azishushu kakhulu xa zisetyenziswa.

Ubushushu beCurie be-nickel-zinc ferrite bungaphezulu kwe-100°C. Kanye njenge-ferrite ephezulu yokuqhuba, kubaluleke kakhulu ukuqiniseka ukuba undoqo kazibuthe awubi shushu kunobushushu beCurie xa isiguquli (inductor) sisebenza. Oku kubaluleke kakhulu kwiimveliso zethu ezisetyenziswa ngokuqhelekileyo zenickel-zinc, ezifana ne-i-shaped inductors, ii-inductors ezimile okwentonga, kunye ne-nickel-zinc toroidal inductors.

Ubushushu beCurie bondoqo we-alloy powder bungaphezulu kwe-450℃, ephakame kakhulu. Kule meko, kufuneka silumke ngakumbi malunga nendlela amanye amacandelo e-transformer (inductor) anokuphatha ngayo ubushushu.

Eli nqaku livela kwi-Intanethi kwaye lelombhali walo wokuqala.
