Abahlinzeki bemishini yempendulo yamandla yeziguquli zefrikhwensi bakukhumbuza ukuthi ngokuthuthukiswa kobuchwepheshe bokukhiqiza obuzenzakalelayo bezimboni, abasebenzisi bakhathazeke kakhulu ngokusetshenziswa kweziguquli zefrikhwensi. Ngokwezinjongo zabo ezihlukene, iziguquli zemvamisa zingahlukaniswa zibe izigaba ezimbili: iziguquli zemvamisa yenhloso ejwayelekile kanye neziguquli ezizinikezele zefrequency.
1. I-Universal frequency converter
I-Universal frequency converter iwuhlobo oluningi kakhulu futhi olusetshenziswa kabanzi emndenini wesiguquli semvamisa. Njengoba igama liphakamisa, isici se-universal frequency converter wukusebenziseka kwayo ngezindlela eziningi. Ngokuthuthukiswa kobuchwepheshe bokuguqula imvamisa kanye nokwanda okuqhubekayo kwesidingo semakethe, iziguquli zemvamisa yendawo yonke zithuthuka ngezindlela ezimbili: eyodwa iyisiguquli esibiza kancane nesilula esivamile esenza imisebenzi ethile yesistimu ibe lula ngokonga amandla njengenjongo eyinhloko. Isetshenziswa kakhulu ezimweni lapho ukusebenza kokulawulwa kwesivinini sesistimu kungabi phezulu, njengamaphampu amanzi, abalandeli, ama-blower, njll., futhi kunezinzuzo zesayizi encane kanye nenani eliphansi; Okwesibili, ohlelweni lokuklama, ama-converter ahlukahlukene asebenza kahle kakhulu futhi asebenza ngezindlela eziningi ahlangabezana nezidingo zohlelo lokusebenza acatshangelwa ngokugcwele. Ngesikhathi sokusetshenziswa, abasebenzisi bangakhetha ama-algorithms ukusetha imingcele ehlukahlukene yesiguquli semvamisa ngokuya ngezimpawu zomthwalo, futhi bangakhetha izinketho ezahlukahlukene eziyisipele ezinikezwe umenzi ukuze kuhlangatshezwane nezidingo ezikhethekile zohlelo. Iziguquli ezihamba phambili ze-multifunctional universal frequency converters zingasetshenziswa kuphela kuzo zonke izinkambu zohlelo lwe-converter elula, kodwa futhi zisetshenziswa kabanzi kumakheshi, amathuluzi omshini we-CNC, izimoto zikagesi nezinye izikhathi ezidinga ukusebenza okuphezulu kwezinhlelo zokulawula isivinini.
Esikhathini esedlule, iziguquli zefrikhwensi yendawo yonke zazisebenzisa ngokuyinhloko indlela yokulawula ye-U/f enesakhiwo sesekhethi esilula, esasinokusebenza kokulawula kwetorque okungekuhle uma kuqhathaniswa nendlela ye-VC. Kodwa-ke, ngokuthuthukiswa kobuchwepheshe bokuguqula imvamisa, abanye abakhiqizi sebevele bethule iziguquli zemvamisa yendawo yonke zisebenzisa i-VC ukuhlangabezana nokuncintisana okushubile emakethe yokuguqula imvamisa. Lesi siguquli semvamisa esisebenza ngezindlela eziningi singashintshelwa kumodi "yokusebenza kokulawula kwe-U/f" noma "i-VC operation" ngokwezidingo zomsebenzisi, kodwa intengo yaso ihambisana neziguquli ze-U/f zemodi yendawo yonke. Ngakho-ke, ngokuthuthukiswa kobuchwepheshe bamandla kagesi kanye nobuchwepheshe bekhompiyutha, ukuphumelela kwezindleko zokuguqulela ama-frequency kuzoqhubeka nokuba ngcono esikhathini esizayo.
2. Isiguquli sefrikhwensi esikhethekile
(1) Ukusebenza okuphezulu okuzinikele kokuguqula imvamisa.
Ngokuthuthukiswa kwethiyori yokulawula, ithiyori yokulawula isivinini se-AC, namandla kagesi, i-VC yama-asynchronous motors yakhiwe. Uhlelo lwe-AC servo olwakhiwe iziguquli zefrikhwensi ze-VC kanye namamotho awo azinikezele afinyelele futhi adlula uhlelo lwe-DC servo. Ngaphezu kwalokho, ngenxa yokuguquguquka okuqinile kwemvelo kanye nokugcinwa okulula kwama-asynchronous motors, okuyizinzuzo eziningi izinhlelo ze-DC servo ezingenazo, iziguquli zemvamisa ye-AC servo ezisebenza kahle kakhulu zishintsha kancane kancane amasistimu we-DC servo ngezidingo zokulawula isivinini esikhulu nokunemba okuphezulu.
(2) Isiguquli sefrikhwensi ephezulu.
Amamotho anesivinini esikhulu avame ukusetshenziswa emishinini yokunemba kwe-ultra. Ukuze kuhlangatshezwane nezidingo zayo zokushayela, kuvele isiguquli sefrikhwensi ephezulu elawulwa yi-PAM, enemvamisa yokuphuma efinyelela ku-3 kHz kanye nesivinini esikhulu esingu-18000 r/min lapho ushayela izigxobo ezimbili ezingavumelaniyo.
(3) Isiguquli se-voltage ephezulu.
Ama-inverter kagesi aphezulu ngokuvamile ama-inverter anamandla amakhulu anamandla amakhulu angu-5000 kW kanye namazinga kagesi angu-3 kV, 6 kV, kanye no-10 kV.
