Intshayelelo:

Iitransformer zidlala indima ebalulekileyo kwiinkqubo zombane zanamhlanje, zivumela ukudluliselwa kwamandla ombane ngokufanelekileyo phakathi kwamanqanaba ahlukeneyo e-voltage. Phakathi kweentlobo ezahlukeneyo zeetransformer, iitransformer zesigaba sesithathu zibaluleke kakhulu kubavelisi. Ezi zixhobo zombane eziqinileyo zenzelwe ukujongana nezicelo zoshishino ezinamandla aphezulu kwaye zisetyenziswa kakhulu kwizityalo zokuvelisa umbane, kwizakhiwo zokuvelisa, nakwiinethiwekhi zokusasaza. Kweli nqaku, siza kujonga izinto ezibalulekileyo kunye nemisebenzi yeetransformer zesigaba sesithathu, sixoxa ngokubaluleka kwazo kubavelisi.

Iziseko zeTransformers zeSigaba eSithathu

Iitransformer zesigaba sesithathu zibalulekile kwiinkqubo zamandla ombane apho kuveliswa okanye kusasazwa khona amandla ombane esigaba sesithathu. Zenzelwe ukubonelela ngemveliso elinganayo ngokwahlula ii-windings eziphambili nezesibini zibe ziiyunithi ezintathu ezahlukeneyo kodwa ezifanayo. I-winding nganye iqhagamshelwe kwenye yezigaba ezintathu: A, B, kunye no-C. Olu lungiselelo luqinisekisa ukuba amandla anikezelwa kwisigaba ngasinye alingana, nto leyo evumela ukuhanjiswa kwamandla ngokufanelekileyo.

Iitransformer zesigaba esithathu ziqulathe izinto ezintathu eziphambili: umbindi, iiwindings, kunye nenkqubo yokufakelwa ubushushu. Umbindi uhlala wakhiwe kusetyenziswa amaphepha esinyithi axhonywe ngomgangatho ophezulu anciphisa ukulahleka kombane we-eddy kunye nokuvuza kwe-magnetic flux. La maphepha ahlanganiswa ndawonye ukuze enze isekethe yemagnethi evaliweyo, ebonelela ngendlela engathathi cala kwintsimi yemagnethi. Ukufakelwa ubushushu obupheleleyo phakathi kweewindings kunye nombindi kubalulekile ukuthintela ukuqhekeka kombane nokuqinisekisa ukusebenza okuthembekileyo.

- Uyilo oluPhambili kunye noLwakhiwo:

Uyilo kunye nokwakhiwa kwesiseko kuchaphazela kakhulu ukusebenza kunye nokusebenza kakuhle kwe-transformer yesigaba esithathu. Ii-cores zingakhiwa ngeemilo ezahlukeneyo, kubandakanya ii-cores ezinee-rectangular, cruciform, okanye uyilo olujikelezayo. Imo nganye inika iingenelo ezahlukeneyo ngokwexabiso, ukusasazwa kwe-magnetic flux, kunye nokulahleka. Ii-cores eziziingxande, umzekelo, zixhaphake kakhulu kwii-transformers ezinkulu, njengoko zibonelela ngozinzo olungcono loomatshini, ngelixa ii-cores eziziingxande zithandwa kwii-transformers ezincinci ngenxa yobulula bazo kunye nokusebenza kakuhle kweendleko.

Ii-cores zihlala zakhiwa ngokugquma amaphepha amancinci entsimbi yombane yodidi oluphezulu, nto leyo enciphisa ilahleko yamandla e-eddy.

Ii-windings kwi-transformer yezigaba ezintathu zibalulekile ekudluliseleni amandla kwaye zahlulwe zibe ziindidi ezimbini: ii-windings eziphambili kunye nee-windings zesibini. Ii-windings eziphambili ziqhagamshelwe kumbane, ngelixa ii-windings zesibini ziqhagamshelwe kumthwalo okanye kwezinye ii-transformers. Zombini ii-windings zeprayimari nezesibini zenziwe ngee-turns ezininzi ze-copper okanye i-aluminium wire insulated. Inani lee-turns kwi-winding nganye likhethwa ngononophelo ukuze kufezekiswe umlinganiselo wokuguqulwa kwe-voltage ofunekayo.

Ulungiselelo lokujikajika kwiitransformer zesigaba esithathu lunokwahluka, kuxhomekeke kwi-voltage yokuphuma efunekayo kunye nolwakhiwo loqhagamshelo. Iindidi ezimbini eziqhelekileyo zoqhagamshelo lokujikajika zii-delta (∆) kunye ne-wye (Y). Kwiitransformer eziqhagamshelene ne-delta, ukujikajika ngakunye kuqhagamshelene phakathi kwezigaba ezibini, nto leyo ebangela umthwalo olinganayo. Iitransformer eziqhagamshelene ne-wye, kwelinye icala, zinesiphelo esinye sokujika ngakunye okubotshelelwe kwindawo engathathi cala okanye esezantsi, ukuqinisekisa ii-voltages kunye nemisinga elinganayo. Ukukhetha uqhagamshelo lokujikajika kuxhomekeke kwiimfuno zesicelo kunye noyilo lwenkqubo iyonke.
