Abahlinzeki bemishini yempendulo yamandla yeziguquli zefrikhwensi bakukhumbuza ukuthi abantu abaningi abanakho ukuqonda okucacile komehluko othile kanye nokusetshenziswa kweziguquli zefrikhwensi namadivayisi okonga amandla. Imishini eminingi yokonga amandla emakethe iyisinxephezelo samandla noma imikhiqizo yokuvikela ugesi oweqile esebenzisa isihlungi samandla kagesi aphezulu kanye nobuchwepheshe bokumunca amandla ukuze imunce ngokuzenzekelayo amandla okungenzeka ahlehlayo wezinto zamandla anamandla kagesi futhi iqhubeke iwubuyisela emlayishweni, isindisa ugesi othathwa into kagesi kugridi yamandla kagesi aphezulu. Umthelela wokonga amandla umaphakathi futhi unomphumela omncane.
Isiguquli sefrikhwensi silungisa imisinga ehlukene edingwa izinto zikagesi ngenxa yezinguquko ezimweni zokusebenza ngokulawula imvamisa. Ikakhulukazi iqukethe ukulungiswa (i-AC kuya ku-DC), ukuhlunga, ukuguqulwa (i-DC kuya ku-AC), iyunithi yokubhuleka, iyunithi yokushayela, iyunithi yokubona, iyunithi ye-microprocessor, njll. Isiguquli sefrikhwensi silungisa i-voltage kanye nemvamisa yokuphuma kwamandla okuphumayo ngokunqamula i-IGBT yangaphakathi, inikeze amandla kagesi adingekayo ngokuvumelana nezidingo zangempela zenjini, ngaleyo ndlela kuzuzwe ukonga amandla kanye nokulawulwa kwesivinini. Ukwengeza, isiguquli semvamisa siphinde sibe nemisebenzi eminingi yokuvikela, efana ne-overcurrent, overvoltage, ukuvikela ukugcwala ngokweqile, njll. Ngokuthuthukiswa okuqhubekayo kokuzenzakalela kwemboni, iziguquli zemvamisa nazo zisetshenziswe kabanzi.
Isizathu sokuthi kungani abaguquli bemvamisa bekwazi ukuzuza ukonga amandla nokonga amandla ezimweni eziningi ukuthi isiguquli semvamisa silawula isivinini semoto.
Imfuneko yesiguquli sefrikhwensi ukuze sizuze ukonga amandla izici zayo zokulawula isivinini somthwalo. Ezingxenyeni eziyisipele ezinomthelela omkhulu emandleni, njengamafeni e-centrifugal namaphampu amanzi amaphakathi, umphumela wokulungiswa kwesiguquli semvamisa kufanele ube ngcono kakhulu kunalowo ngemva kokusebenza kwaso sokulawula isivinini. Ngaphansi kwalesi sisekelo, isiguquli sefrikhwensi singazuza ukonga amandla kanye nemiphumela yokonga
Uma izingxenye eziyisipele ezicutshungulwa isiguquli se-frequency ziyimithwalo ye-torque engaguquki noma imithwalo yamandla engaguquki, ukuncipha kwamandla akubalulekile noma amandla ahlala engashintshi lapho isivinini sincipha. Ngakho-ke, ukusetshenziswa kweziguquli zefrikhwensi akukwazi ukuzuza umphumela ofanayo wokonga amandla njengakuqala, futhi akukwazi ngisho nokuwonga ugesi nhlobo
Isizathu esiyinhloko sokuthi kungani amadivaysi okonga amandla ehluke kwiziguquli zemvamisa ukuthi:
Okokuqala, ubuchwepheshe bokuguqula imvamisa bungobunye kuphela kobuchwepheshe obuningi bokonga amandla, obuhlanganisa amasu ahlukahlukene afana nokulawulwa kwamandla kagesi kanye nomkhawulo wamanje, isinxephezelo sesici samandla, ukulawulwa kwamandla alawulwa yisigaba, ukuguqulwa kwamafrikhwensi, ukusika, ukuhlunga, impendulo yamandla, njll. Ngisho nakumadivayisi okonga amandla asebenzisa izimiso zokuguqulwa kwemvamisa, iziguquli zefrikhwensi ziyiyunithi eyodwa kuphela edivayisini yokonga ugesi;
Okwesibili, ucwaningo nokuklanywa kwedivayisi yokonga amandla kucabangela izidingo ezihlukahlukene zokulawula zesayithi lesicelo, futhi linemisebenzi yokulawula ehlukahlukene okulula ukuyisebenzisa esizeni, njengezinga lokushisa nokucindezela kokulawula iluphu evaliwe;
Okwesithathu, ezindaweni eziningi zezimboni, ukufaka izintambo ngokuqondile kanye nokufaka ama-frequency converters akuhambelani nezindinganiso zikagesi futhi kungabangela kalula izingozi ezihlukahlukene zokuphepha. Ukufaka isethi ephelele yemishini yokonga amandla kunganciphisa ukwenzeka kwezingozi;
Okwesine, ucwaningo nokuklanywa kwedivayisi yokonga amandla kucabangela ngokugcwele ukuvikelwa kokuphepha kwesiguquli sefrikhwensi esakhelwe ngaphakathi, ukusetha amasekhethi okuvikela umbani, amasekhethi okuvikela ukugcwala ngokweqile, nemisebenzi ye-alamu yamaphutha ukuze kuncishiswe ukulimala kwengozi kwesiguquli sefrikhwensi ngokwaso.
Okwesihlanu, ngokwezidingo zangempela zesizinda sokukhiqiza, amadivaysi okonga amandla ngokuvamile ahlome ngezinhlelo ze-bypass ezisebenza kahle, ezingaqinisekisa ukuqhubeka kahle kokukhiqizwa kwesayithi ngisho nalapho kwenzeka ukwehluleka okungalindelekile kuyunithi yokulawula isivinini.
Okwesithupha, njengoba kwaziwa kahle, abaguquli bemvamisa bakhiqiza ama-harmonics athile ngesikhathi sokusebenza. Ezingosini eziningi zokukhiqiza, inani elikhulu lokuphazanyiswa kwe-harmonic ngokuvamile libangela ukungasebenzi kahle kwemishini noma ngisho nomonakalo. Lapho ucwaninga futhi uklama amadivayisi okonga amandla, amabhizinisi amakhulu okonga amandla ngokuvamile afaka izisetshenziswa zokuhlunga ezivumelanayo ngaphakathi kwemishini yokonga amandla ukuze ahlunge ama-harmonic amaningi esizeni, okubalulekile ekukhiqizeni ukuphepha kwamakhasimende.
