Asebenza Kanjani Amashaja Asheshayo Okupholisa Uketshezi?

Amashaja asheshayo okupholisa uketshezi asebenzisa izintambo ezipholise uketshezi ukusiza ukulwa namazinga aphezulu okushisa ahlobene nesivinini sokushaja okuphezulu. Ukupholisa kwenzeka kusixhumi ngokwaso, sithumela isipholile esigeleza ngekhebula futhi singene ekuxhumaneni phakathi kwemoto nesixhumi. Ngenxa yokuthi ukupholisa kwenzeka ngaphakathi kwesixhumi, ukushisa kuyaphela cishe ngaso leso sikhathi njengoba isipholile siya emuva naphambili phakathi kweyunithi yokupholisa nesixhumi. Amasistimu okupholisa uketshezi olusekelwe emanzini angakwazi ukuqeda ukushisa kuze kufike izikhathi ezingu-10 ngendlela efanele, futhi olunye uketshezi lungathuthukisa ukusebenza kahle kokupholisa. Ngakho-ke, ukupholisa uketshezi kuthola ukunakwa okwengeziwe njengesixazululo esisebenza kahle kakhulu esitholakalayo.

Ukupholisa uketshezi kuvumela izintambo zokushaja ukuthi zibe mncane futhi zibe lula, kunciphisa isisindo sekhebula cishe ngo-40%. Lokhu kwenza kube lula kumthengi ojwayelekile ukuthi azisebenzise uma eshaja imoto yakhe.

Izixhumi zoketshezi olupholisa uketshezi ziklanyelwe ukuthi ziqine futhi zimelane nezimo zangaphandle ezifana namazinga aphezulu okushisa, amakhaza, umswakama nothuli. Futhi zenzelwe ukumelana nenani elikhulu lokucindezela ukuze zigweme ukuvuza futhi zizisekele phakathi nesikhathi eside sokushaja.

Inqubo yokupholisa uketshezi yamashaja emoto kagesi ngokuvamile ihlanganisa isistimu evaliwe. Ishaja ifakwe isishintshi sokushisa esixhunywe kusistimu yokupholisa, okungaba ukupholiswa komoya noma ukupholisa uketshezi. Ukushisa okukhiqizwa ngesikhathi sokushaja kudluliselwa kusishintshisi sokushisa, esibe sesikudlulisela kusipholisi. Isipholile ngokuvamile siyingxube yamanzi kanye nesengezo esipholile, njenge-glycol noma i-ethylene glycol. Isipholile sizungeza kusistimu yokupholisa yeshaja, imunca ukushisa futhi ikudlulisele kurediyetha noma isishintshi sokushisa. Ukushisa bese kuchithwa emoyeni noma kudluliselwe ohlelweni lokupholisa uketshezi, kuye ngokuthi ishaja yakhiwe kanjani.

Ingaphakathi lesixhumi esinamandla aphezulu se-CSS libonisa izintambo ze-AC (eziluhlaza) kanye nokupholisa uketshezi kwezintambo ze-DC (ezibomvu).

Ngokupholisa okuwuketshezi koxhumana nabo kanye nesipholile esisebenza kahle kakhulu , isilinganiso samandla singakhushulwa sifike ku-500 kW (500 A ku-1000V) esingaletha ukushajwa kwebanga lamamayela angu-60 emizuzwini emithathu kuya kwemihlanu.
