Ngokusetshenziswa kabanzi kwe-variable speed drive, i-servo, ups neminye imikhiqizo, inani elikhulu lama-harmonics livele kugridi yamandla, futhi ama-harmonics alethe izinkinga ezinkulu kakhulu zekhwalithi yamandla.Ukuze kuxazululwe inkinga ye-harmonic kugridi yamandla, inkampani yethu ithuthukise amazinga amathathuisihlungi esisebenzayongokusekelwe kusihlungi esisebenza ngamaleveli amabili.
Isihlungi se-harmonic esisebenzayoingasetshenziswa kabanzi kumanethiwekhi okusabalalisa ezimboni, ezentengiselwano kanye nezikhungo, njengalezi: izinhlelo zamandla, amabhizinisi e-electrolytic plating, izinto zokuhlanza amanzi, amabhizinisi e-petrochemical, izitolo ezinkulu ezinkulu nezakhiwo zamahhovisi, amabhizinisi e-precision electronics, amasistimu kagesi esikhumulweni sezindiza/amachweba, izikhungo zezokwelapha. , njll. Ngokwezinto ezihlukene zohlelo, ukusetshenziswa kweisihlungi samandla asebenzayoizodlala indima ekuqinisekiseni ukwethembeka kokuphakelwa kukagesi, ukunciphisa ukuphazamiseka, ukuthuthukisa ikhwalithi yomkhiqizo, ukwandisa ukuphila kwemishini kanye nokunciphisa ukulimala kwemishini.
I-harmonic yesi-3 ezimbonini eziningi ze-semiconductor ibucayi kakhulu, ikakhulukazi ngenxa yenani elikhulu lemishini yokulungisa yesigaba esisodwa esetshenziswa emabhizinisini.I-harmonic yesithathu ingeye-harmonics yokulandelana eyiziro, enezici zokuqoqa emugqeni ongathathi hlangothi, okuholela ekucindezelweni okukhulu emugqeni ongathathi hlangothi, kanye nesenzakalo sokuthungela, esinezingozi ezinkulu ezifihliwe ekuphepheni kokukhiqiza.Ama-Harmonics angabangela futhi ukuthi ama-circuit breaker ahambe, abambezele isikhathi sokukhiqiza.I-harmonic yesithathu yakha ukujikeleza ku-transformer futhi isheshisa ukuguga kwe-transformer.Ukungcoliswa kwe-harmonic okukhulu kuzothinta nakanjani ukusebenza kahle kwesevisi nempilo yezinto zokusebenza ohlelweni lokusabalalisa amandla.
Iningi lezixhumanisi zokulungiswa kwe-inverter ukusetshenziswa kwama-pulses angu-6 ukuguqula i-AC ibe yi-DC, ngakho-ke ama-harmonics akhiqizwayo ikakhulukazi izikhathi ezingu-5, 7, 11.Izingozi zayo eziyinhloko izingozi emishinini kagesi kanye nokuchezuka esilinganisweni.Ukusetshenziswa kweisihlungi esisebenzayokungaba yisixazululo esihle sale nkinga.
Ukusetshenziswa kwei-harmonic esebenzayoisihlungi:
1. Hlunga ama-harmonics amanje, angahlunga kahle ama-harmonics izikhathi ezingu-2-25 kumthwalo wamanje, ukuze enze inethiwekhi yokusabalalisa ihlanzeke futhi isebenze kahle, futhi ihlangabezane nezidingo zezinga likazwelonke lokusika inethiwekhi yokusabalalisa.Isihlungi esisebenzayo isinxephezelo sokulandelela esivumelana nezimo ngempela, singakwazi ukuhlonza ngokuzenzakalelayo izinguquko eziphelele zomthwalo kanye nokulayisha izinguquko zokuqukethwe kwe-harmonic futhi silandelele ngokushesha isinxephezelo, impendulo engu-80us ekushintsheni kokulayisha, 20ms ukuzuza isinxephezelo esigcwele sokulandelela.
2. Ukuthuthukisa ukungalingani kwesistimu, kungaqeda ngokuphelele ukungalingani kwesistimu okubangelwa ama-harmonics, esimweni sezimvume zomthamo wemishini, zingasethwa ngokusho komsebenzisi ukuze kunxeshezelwe uhlelo oluyisisekelo lokulandelana okungalungile kanye nezingxenye zokungalingani kokulandelana kwe-zero kanye nesinxephezelo esilinganiselwe amandla asebenzayo.
3. Vimbela ukuzwakala kwegridi yamandla, engeke izwane negridi yamandla, futhi ingalingisa ngokuphumelelayo ukuzwakala kwegridi yamandla ngokwayo ngaphakathi kobubanzi bomthamo wayo.
4. Izinhlobonhlobo zemisebenzi yokuvikela, ene-over yamanje, phezu kwamandla kagesi, ngaphansi kwamandla kagesi, izinga lokushisa eliphezulu, iphutha lesekhethi yokukala, ukushaywa kombani neminye imisebenzi yokuvikela.
5. Ukusebenza okugcwele kwedijithali, okune-interface enobungane yomshini womuntu, okwenza umsebenzi ube lula, ukusebenziseka kalula nokuwunakekela.
