Abahlinzeki bempahla yempendulo yamandla banikhumbuza ukuthi amayunithi empendulo yokubuyisela angakwazi ukuphendula ngesikhathi nangempumelelo amandla kagesi aguqulwa esuka kumandla we-kinetic noma angaba namandla emishini yokukhiqiza aye kugridi yamandla, onge amandla ngempumelelo; Futhi kungakhathaliseki ukuthi kusesimweni sokulungiswa noma sempendulo, ama-voltage kanye namagagasi amanje ohlangothini lwegridi yeyunithi yempendulo yokulungiswa amagagasi e-sinusoidal anokuqukethwe okuvumelanayo okuncane kakhulu, futhi isici samandla siseduze noku-1, ngokuyisisekelo sisusa ukuphazamiseka kwe-harmonic kwesiguquli sefrikhwensi kugridi kanye nokuzuza ngempela ukusetshenziswa kukagesi ovumelana nemvelo.
Iyunithi yempendulo yokulungisa ingabuyisela amandla amoshekile ezintweni ezimelana nezidla amandla ezinhlelweni ezivamile zokuguqulela imvamisa kugridi yamandla, konga ugesi omningi futhi kuzuzwe izinzuzo ezinkulu zomphakathi nezomnotho; Futhi ingathuthukisa isici samandla wemishini kagesi kanye negridi yamandla, inciphise umthamo wokusabalalisa wamakhasimende, futhi ithuthukise ukusebenza kahle kohlelo lokusabalalisa.
Ngakho-ke, amayunithi empendulo yokulungisa angakhuthaza ukongiwa kwamandla kanye nokunciphisa ukungcola, akhuthaze ukuthuthukiswa okuvumelana kwemvelo nezinsiza, futhi abe nezinzuzo ezibalulekile zezomnotho nezenhlalo.
Izici eziyinhloko zomkhiqizo:
1. Ingathuthukisa isici samandla okokufaka endaweni yokudlulisela; Yehlisa ukungcoliswa kwe-harmonic kugridi yamandla;
2. Ngeke kube khona igebe likagesi wokushintsha futhi ngeke kube nenkinga yokuhluleka kokuhamba.
Ngamandla kagesi anokuguquguquka okuphawulekayo, ngisho noma i-voltage yehla ngaphansi kuka-80% we-voltage elinganiselwe, i-voltage yebhasi ye-DC ezinzile isengaqinisekiswa.
4. Ukwamukela i-IGBT yesizukulwane sesine, umjikelezo wamandla kanye nomjikelezo wokushisa we-IGBT uthuthukiswa kakhulu; Ukwamukela ama-capacitor efilimu ye-metalized polypropylene eyomile, anempilo ende yesevisi, ububanzi obubanzi bokushisa obusebenzayo, futhi akukho kungcola kwemvelo.
5. I-voltage evumelana nezimo ezinhle, ifaneleka kakhulu igridi yamandla asekhaya, i-voltage engu-380V+15%/-20%; 460V+15%/-20%; 690V+15%/-20%.
6. Ine-Profibus DP futhi Ingakwazi ukuvula imisebenzi yokuxhumana, engakwazi ukuxhumana nekhompyutha ephezulu futhi izuze ukuqapha.
7. Inemisebenzi yokubona ukulandelana kwesigaba esizenzakalelayo kanye nemisebenzi yokuvumelanisa, okwenza kube lula ukuyisebenzisa; Azikho izilungiselelo zepharamitha ezidingekayo, kulula ukuzisebenzisa.
8. Inemisebenzi eminingi yokuvikela efana ne-overvoltage, undervoltage, iphutha eliphansi, ukutholwa kwesigaba semoto, overcurrent, overtemperature, overcurrent, overtemperature, current limiting, phase loss, short circuit, ukuxhumana, njll.
Izinkambu ezisebenzayo:
Izinhlobo ezahlukahlukene zamamayini;
Izisetshenziswa zokuguqulwa kwamandla okungaba khona kwamakheshi ahlukahlukene okwakha kanye namachweba, okhreni, njll;
Imishini yokuhlola ukukhiqiza yezinhlobo zokudonsa njengama-dynamometers nemibhede yokuhlola yesitimela;
Emkhakheni wokukhiqiza amandla amasha njengamandla omoya namandla elanga.
