Curie ubushyuhe bwa transformateur yibanze

“Igihe cyashize, umuntu yabajije niba ingirabuzimafatizo ifite igipimo cyo kurwanya ubushyuhe. Umuntu arasubiza gutya:

Urwego rwo kurwanya ubushyuhe ni urwego rwo kubika ibikoresho. Imikorere ya magnetiki ntabwo ifatwa nkibikoresho byigenga, ntabwo rero ifite urwego rwihariye rwo kurwanya ubushyuhe. Ariko ifite ibipimo bikomeye bijyanye nubushyuhe bwitwaUbushyuhe bwa Curie. '

Uyu munsi, reka tuganire kubyerekeye 'Ubushyuhe bwa Curie'ya rukuruzi.

Ubushyuhe bwa Curie, buzwi kandi nka point ya Curie cyangwa point de magnetique, ni mugihe imbaraga za magnetique imbaraga zibintu zigabanuka kugeza kuri 0 nkuko zishyushye. Yavumbuwe na Cury mu mpera z'ikinyejana cya 19: iyo ushyushye rukuruzi kugeza ku bushyuhe runaka, magnetisme yumwimerere irazimira.

Muri transformateur (inductors), niba irukuruziUbushyuhe burenze hejuru yubushyuhe bwa Curie, burashobora gutuma inductance igabanuka kuri 0. Mugihe ibicuruzwa byinshi bishobora kugarura imikorere yabyo nyuma yo gukonja, kubihindura (inductors) bikora, kugira inductance zeru bizananira kunanirwa no gucanwa.

Iyo rero gushushanya no guhitamoimpinduka.

Ubushyuhe bwa Curie bwimbaraga manganese-zinc ferrite irenga 210 ° C. Ibikoresho byinshi byo guhinduranya (inductor) bifite ubushyuhe buri munsi yibi, bityo mugihe cyo gukora, imbaraga za rukuruzi ntizigera ku bushyuhe bwo hejuru. ”

Ubushyuhe bwa Curie bwa ferrite ya manganese-zinc irenga 110 ° C. Ibikoresho byinshi bya transformateur (inductor) birashobora gukoresha ubushyuhe burenze ibi, kandi ubushyuhe bwa transformateur (inductor) nyuma yo gukora burashobora kujya hejuru yibi. Rero, dukeneye rwose kwitondera uburyo dushushanya imiyoboro ya magnetiki ikora cyane kugirango tumenye ko idashyuha cyane mugihe ikoreshwa.

Ubushyuhe bwa Curie bwa nikel-zinc ferrite burenga 100 ° C. Nka hamwe na ferrite ikora cyane, nibyingenzi birakomeye kugirango umenye neza ko imbaraga za magneti zidashyuha kurenza ubushyuhe bwa Curie mugihe transformateur (inductor) ikora. Ibi ni ingenzi cyane cyane kubicuruzwa byacu bikoreshwa na nikel-zinc, nka inductors zimeze nka I, inductors zimeze nkinkoni, hamwe na nikel-zinc toroidal.

Ubushyuhe bwa Curie bwa porojeri ya porojeri irenga 450 ℃, ni hejuru cyane. Muri iki kibazo, tugomba kwitonda cyane kubijyanye nibindi bice bigize transformateur (inductor) bishobora gukoresha ubushyuhe.

Iyi ngingo iva kuri interineti kandi ni iy'umwanditsi wambere.
