Isandulelo: Empilweni yethu yansuku zonke kanye nenqubo yokukhiqiza, umthwalo ongalingani wezigaba ezintathu uvame ukwenzeka.Inkinga yokusetshenziswa kukagesi ibilokhu iyinakwa yezwe, ngakho-ke sidinga ukuqonda umgomo wokuba khona kokungalingani kwezigaba ezintathu.Qonda izingozi nezisombululo zokungalingani kwezigaba ezintathu.
Isimiso sokungalingani kwezigaba ezintathu ukuthi ama-amplitudes wesigaba sesithathu samanje noma i-voltage ohlelweni lwamandla awahambisani.Umehluko we-amplitude udlula ububanzi obushiwo.Ukusatshalaliswa komthwalo okungalingani kwesigaba ngasinye, ukungefani kokusetshenziswa kwamandla omthwalo oqondile kanye nokufinyelela komthwalo wamandla aphezulu wesigaba esisodwa yizizathu eziyinhloko zokungalingani kwezigaba ezintathu.Kuphinde kubandakanye nokungeneli kokwakhiwa kwegridi kagesi, ukuguqulwa nokusebenza nokugcinwa kahle, okuyisizathu esinenjongo.Ukuze unikeze isibonelo esilula, ekuphileni kwansuku zonke, izinto eziningi zasendlini kanye nemishini yokukhanyisa ziyimithwalo yesigaba esisodwa.Ngenxa yenani elikhulu nezikhathi ezihlukene zokuvula, amandla kagesi abanye abasebenzisi azoba phansi, okuzoholela ekuhlulekeni kwezinye izinto zikagesi ukusebenza ngendlela evamile.Amandla kagesi aphezulu wabanye abasebenzisi azodala ukulimala okubi kakhulu ekugugeni kwamasekethe nama-insulators.Lokhu kungafingqwa njengomonakalo odalwe ukungalingani kwezigaba ezintathu.
Ukulimala okubangelwa ukungalingani kwezigaba ezintathu ngowokuqala ukuthwala umonakalo ku-transformer.Ngenxa yomthwalo ongalingani wezigaba ezintathu, i-transformer isebenza esimweni se-asymmetric, okuholela ekwandeni kokulahlekelwa kwamandla kagesi, okuhlanganisa ukulahlekelwa okungekho nokulahlekelwa komthwalo.I-transformer igijima ngaphansi kwesimo esingalingani somthwalo wesigaba sesithathu, esizodala ubuningi bamanje.Ukushisa kwezingxenye zensimbi zendawo kuyanda, futhi kuze kuholele ekulimaleni kwe-transformer.Ikakhulukazi, ukulahlekelwa kwethusi kwe-transformer kwanda, okungagcini nje ukunciphisa izinga lokukhipha amandla kagesi, kodwa futhi kubangela kalula ukulinganisa okungalungile kwamandla kagesi.
Ngaphezu kokulimala kwe-transformer, inomthelela kwezinye izinto zikagesi, ngoba ukungalingani kwe-voltage yesigaba sesithathu kuzoholela ekungalinganini kwamanje, okuzokwandisa izinga lokushisa kwemoto, kwandise ukusetshenziswa kwamandla, futhi ukhiqize ukudlidliza.Impilo yesevisi yemishini kagesi iyancipha kakhulu, futhi izindleko zokugcinwa nokulungisa imishini yansuku zonke ziyanda.Ikakhulukazi uma kwenzeka ukulayisha ngokweqile kanye nesifunda esifushane, kulula ukubangela okunye ukulahlekelwa (njengomlilo).Ngesikhathi esifanayo, njengoba i-voltage kanye nokungalingani kwamanje kwanda, lokhu kwandisa nokulahlekelwa komugqa wesifunda.
Njengoba sibhekene nokungalingani kwezigaba ezintathu osekudalele umonakalo omningi, kufanele siqhamuke kanjani nezisombululo?Okokuqala kufanele kube ukwakhiwa kwegridi yamandla.Ekuqaleni kokwakhiwa kwegridi kagesi, kufanele ibambisane neminyango kahulumeni efanele ukwenza ukuhlela okuphusile kwegridi kagesi.Lwela ukuxazulula inkinga yokungalingani kwezigaba ezintathu emthonjeni wokuthuthukiswa kwenkinga.Isibonelo, ukwakhiwa kwenethiwekhi yokusabalalisa amandla kufanele kulandele isimiso "somthamo omncane, izindawo zokusabalalisa eziningi, ne-radius emfushane" ekukhethweni kwendawo yama-transformer okusabalalisa.Yenza umsebenzi omuhle wokufaka imitha ye-low-voltage, ukuze ukusatshalaliswa kwezigaba ezintathu kufane ngangokunokwenzeka, futhi ugweme isenzakalo sokuchezuka kwesigaba somthwalo.
Ngesikhathi esifanayo, ngoba ukungalingani kwezigaba ezintathu kuzobangela ukuthi okwamanje kubonakale emgqeni ongathathi hlangothi.Ngakho-ke, ukugxiliswa kwamaphoyinti amaningi komugqa ongathathi hlangothi kufanele kwamukelwe ukuze kuncishiswe ukulahleka kwamandla kolayini ophakathi nendawo.Futhi inani lokumelana lomugqa ongathathi hlangothi akufanele libe likhulu kakhulu, futhi inani lokumelana likhulu kakhulu, elizokwandisa kalula ukulahlekelwa komugqa.
Uma siqonda isimiso sokungalingani kwezigaba ezintathu, ukulimala kwayo kanye nendlela yokubhekana nayo, kufanele silwele ukwenza ibhalansi yezigaba ezintathu.Lapho i-current idlula intambo yolayini kunethiwekhi yokuphakelwa kwamandla, ngenxa yokuthi intambo yolayini ngokwayo inenani lokumelana, izobangela ukulahlekelwa kwamandla okunikezwa kwamandla.Ngakho-ke, lapho isigaba samanje sezigaba ezintathu sikhula ngokulingana, inani lokulahlekelwa kwamandla lesistimu yokunikezela amandla liphansi kakhulu.
Idivayisi yokulawula ukungalingani kwezigaba ezintathu ekhiqizwa yi-Hongyan Electric ingakwazi ukulawula ngempumelelo izinkinga zokungalingani kwezigaba ezintathu, i-voltage ephansi yokugcina, kanye nesinxephezelo se-bidirectional samanje esisebenzayo ekuguquleni nasekuthuthukiseni inethiwekhi yokusabalalisa.
