Nihe ku isi amajwi aturuka muri transformateur?

Ijwi rya transformateur riva imbere muri transformateur. Transformator ishingiye ku ihame rya induction ya electromagnetic, hamwe na coil primaire coing coil hamwe na coil ya kabiri ya coing yashyizwe imbere, hamwe nicyuma cya silikoni hamwe nibikoresho bya magnetiki bihanitse hagati. Mubisanzwe ibihe, coil ihindagurika ya transformateur ibarwa ukurikije igice cyambukiranya igice cyibanze.

Kubera ko hari coil ihindagurika, iyo ihujwe n'amashanyarazi ya AC 50Hz, hazabaho umuyoboro ushimishije.Muri AC core coil, hari ibice bibiri byigihombo, igihombo gihinduka ni igihombo gito cyumuzunguruko, ni ukuvuga gutakaza umuringa, nacyo kigabanyijemo ibice bibiri, aribyo igice cyingufu zikora nigice cyingufu zikora.

Guhindura

 

Iyi "eddy current" yongera igihombo cya transformateur kandi igashyushya intandaro ya transformateur, ikazamura ubushyuhe bwa transformateur.

Hariho gutakaza umuringa RI ²kurwanya coil R no gutakaza icyuma (gutakaza hystereze no gutakaza eddy) mubyuma.Gutakaza ibyuma bigereranywa na Bm ².Iyo inshuro yumuriro w'amashanyarazi ikosowe, gutakaza ibyuma bya coil bifitanye isano na voltage ikora. Ukurikije igitekerezo cyo guhora flux U = 4.44fNBmS, Bm mumurongo ni ugereranije na voltage ikoreshwa.Muyandi magambo, gutakaza ibyuma bigereranywa na kare ya voltage ikoreshwa.

Transformator irashobora gucira urubanza imikorere ikurikije amajwi y'ibikorwa.Uburyo ni ugukoresha impera imwe yinkoni yo gutegera kuri tank ya lisansi ya transformateur, naho indi mpera yegereye ugutwi kugirango wumve neza amajwi.Niba ari ijwi "yuyu" rihoraho, bivuze ko transformateur ikora bisanzwe.Niba amajwi ya "yuyu" aremereye kuruta uko byari bisanzwe, reba ubushyuhe, ubushyuhe bwa peteroli na peteroli ya transformateur kugirango urebe niba biterwa na voltage ikabije cyangwa kurenza urugero, niba atari byo, biterwa ahanini nicyuma cyoroshye.Iyo wunvise amajwi "gusakuza, gusakuza", reba niba hari flashover hejuru yikibaho.Iyo ijwi rya "gutontoma" ryumvikanye, habaho gusenyuka kwimbere.

Nta gutakaza imitwaro igabanijwemo ibice bibiri: gutakaza ingufu zikora no gutakaza ingufu zidasanzwe.Transformer murwego rwa kabiri rufunguye-ruzunguruka leta, primaire iracyafite umuyoboro runaka, hanyuma ukagwizwa na voltage yambere yagenwe bizagira ingufu runaka, iyi mashanyarazi yitwa nta-mutwaro uhari.Gutakaza ingufu zikora ahanini bivuga igihombo cya hystereze hamwe nigihombo cya eddy mumyuma yicyuma, mubisanzwe bisobanurwa mubisobanuro byuruganda cyangwa raporo yikizamini cya transformateur.Igice cyo gutakaza ingufu zidasanzwe ni igihombo cyatewe numuyoboro ushimishije, ugereranije hafi nimbaraga zidafite umutwaro wa transformateur kandi ushobora kubarwa na formula ikurikira ukurikije nta mutwaro uremereye.

Q₀ = I₀ (%) / 100Se

Ikibazo0muri formula yerekana gutakaza imbaraga zidasanzwe mugutakaza imitwaro, mubice bya kvar .;

I₀ (%) bivuga ijanisha rya transformateur nta mutwaro uhari kugeza kugipimo cyagenwe.

S0igipimo cyerekana ubushobozi bwapimwe bwa transformateur muri KVA.

Igice gikora nigihombo cyatewe nokurwanya kwambere kwihinduranya hamwe no guhinduranya kwa kabiri kwa transformateur iyo unyuze mumashanyarazi, ugereranije na kare yumuriro, bityo ubunini bwayo buterwa numutwaro nimbaraga za transformateur.Igice cyo gutakaza ingufu zidasanzwe ni igihombo cyatewe no gutemba, bishobora kubarwa na formula ikurikira.

Qd = Ud (%) / 100Se

Qd muri formula yerekana gutakaza ingufu zumuriro igice cya transfert igihombo gito, mubice bya kvar .;

Ud ni ijanisha rya voltage ngufi ya voltage kuri voltage yagenwe ;

Se bivuga ubushobozi bwagenwe bwa transformateur muri kvA.
