Dab tsi yog qhov DC magnetization phenomenon ntawm transformer

Muaj ib lub sij hawm nyob rau hauv transformers hu ua DC magnetization phenomenon ntawm transformers. Qhov tshwm sim no muaj kev cuam tshuam loj heev rau transformers. DC magnetization tshwm sim: Thaum muaj ib qho DC tivthaiv nyob rau hauv lub thib ob winding ntawm lub rectifier transformer, DC tivthaiv ntws los ntawm lub thib ob winding thiab cov tub ntxhais hlau zoo siab heev. Qhov no yog DC magnetization tshwm sim. Qhov tshwm sim no feem ntau tshwm sim hauv ib nrab-yoj rectifier circuit. Nws qhov kev puas tsuaj yog tias nws yooj yim rau saturate cov tub ntxhais hlau thiab nce qhov poob. Yog li yog tias koj xav pom qhov poob ntawm lub transformer, koj tuaj yeem pom ncaj qha tias DC magnetization phenomenon ntawm transformer yog li cas. Ntau cov txheej txheem tuaj yeem khaws cia hauv nruab nrab. Lub DC magnetization ntawm lub transformer kuj cais.
DC magnetization yog muab faib ua DC pulsating tam sim no magnetization txoj kev thiab DC tas li tam sim no magnetization txoj kev. Tus qub yog qhov yooj yim dua li qhov kawg hauv kev siv hluav taws xob. Nws feem ntau yog siv rau kev sib nqus ntawm cov khoom nyob rau hauv qhov seem magnetic teb nrhiav kom tau txoj kev. Nyob rau hauv active magnetic teb nrhiav kom tau, qhov no magnetization yuav ua rau ib tug muaj zog AC magnetic teb teeb liab nyob rau hauv lub nrhiav kom tau teeb liab, ua rau kom lub complexity ntawm lub nrhiav kom tau teeb liab ua, thiab txo cov teeb liab-rau-suab nrov piv ntawm lub teeb liab nrhiav pom. DC qhov tam sim no magnetization txoj kev muaj cov kev xav tau siab rau qhov tam sim no, thiab qhov excitation tam sim no feem ntau yog ob peb amperes lossis txawm pua ​​pua ntawm amperes. Zoo li AC magnetization txoj kev, DC magnetization txoj kev tau yooj yim kho cov magnetization siv los ntawm kev tswj cov tam sim no, tab sis nrog kev nce ntawm kev siv lub sij hawm tas li, cov cua sov ntawm cov electromagnet yog ib qho nyuaj rau zam.
