Izihlungi zamandla asebenzayoingasetshenziswa 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.
1.Imboni yezokuxhumana
Ukuze kuhlangatshezwane nezidingo zokusebenza kwezikhungo zedatha ezinkulu, amandla e-UPS ohlelweni lokuxhumana nokusabalalisa akhula kakhulu.Ngokusho kocwaningo, imishini eyinhloko yomthombo we-harmonic wesistimu yokusabalalisa i-voltage low-voltage yi-UPS, ukushintshwa kwamandla kagesi, ukuguqulwa kwe-frequency air conditioning nokunye.Okuqukethwe kwe-harmonic kuphezulu, futhi isici samandla okususa lawa madivayisi omthombo we-harmonic aphezulu kakhulu.Ngokusebenzisaisihlungi esisebenzayoingathuthukisa ukuzinza kwesistimu yezokuxhumana kanye nesistimu yokusabalalisa amandla, inwebise impilo yesevisi yemishini yokuxhumana kanye nemishini yamandla, futhi yenze uhlelo lokusabalalisa amandla luhambisane kakhulu nezicaciso zokuklama kwendawo ye-harmonic.
2.Imboni ye-semiconductor
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.
3.Imboni ye-Petrochemical
Ngenxa yezidingo zokukhiqiza, kunenqwaba yemithwalo yepompo embonini ye-petrochemical, futhi imithwalo eminingi yepompo ifakwe ama-inverters.Ukusetshenziswa kwe-frequency converter kukhulisa kakhulu okuqukethwe kwe-harmonic ohlelweni lokusabalalisa amandla embonini ye-petrochemical.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 kwesihlungi esisebenzayo kungaba yisixazululo esihle kule nkinga.
4.Chemical fiber industry
Ukuze kuthuthukiswe kakhulu izinga lokuncibilika, kuthuthukiswe izinga lokuncibilika kwengilazi, kanye nokwelula impilo yesithando nowonga amandla, imishini yokushisa yokuncibilika kagesi ivame ukusetshenziswa embonini ye-chemical fiber, futhi ugesi uthunyelwa ngqo kuhhavini lethangi lengilazi. ukushisisa ngophethiloli ngosizo lwama-electrode.Lawa madivayisi azokhiqiza inani elikhulu lama-harmonics, futhi i-spectrum kanye ne-amplitude ye-harmonics yezigaba ezintathu zihluke kakhulu.
Imboni ye-5.Steel/medium frequency heat
Isithando somlilo esiphakathi nendawo, umshini wokugaya, isithando somlilo se-arc kagesi nezinye izinto ezisetshenziswa embonini yensimbi zizoba nomthelela omkhulu kwikhwalithi yamandla wegridi yamandla, ukuze isenzo sokuvikela isinxephezelo sekhabhinethi ye-capacitor overload sivame, i-transformer namandla Ukushisa komugqa wokuhlinzeka kubucayi, i-fuse ivame ukushaywa, futhi ibangele ngisho nokwehla kwe-voltage, iflicker.
6.Imboni yokukhiqiza izimoto
Umshini wokushisela umshini obalulekile embonini yokukhiqiza izimoto, ngoba umshini wokushisela unezici zokungahleliwe, ngokushesha kanye nomthelela, ukuze inombolo enkulu yemishini yokushisela ibangele izinkinga ezinkulu zekhwalithi yamandla, okuholela kwikhwalithi yokushisela engazinzile, amarobhothi anezinga eliphezulu. I-degree of automation ayikwazi ukusebenza ngenxa yokungazinzi kwamandla kagesi, uhlelo lokunxeshezelwa kwamandla asebenzayo alukwazi ukusetshenziswa ngokujwayelekile.
7.Harmonic control of DC motor
Izikhumulo zezindiza ezinkulu ze-DC zidinga ukuguqula i-AC ibe yi-DC ngokusebenzisa okokusebenza kokulungisa kabusha, ngenxa yokuthi umthamo womthwalo wamaphrojekthi anjalo mkhulu, ngakho kunokungcoliswa okubucayi kwe-harmonic ohlangothini lwe-AC, okuholela ekuphazamisekeni kwamandla kagesi, kanye nezingozi ezimbi.
8.Ukusetshenziswa kwemigqa yokukhiqiza ezenzakalelayo kanye nemishini yokunemba
Emgqeni wokukhiqiza othomathikhi kanye nemishini yokunemba, i-harmonics izothinta ukusetshenziswa kwayo okujwayelekile, ukuze uhlelo lokulawula oluhlakaniphile, uhlelo lwe-PLC, njll., ukwehluleka.
9.Isistimu yesibhedlela
Izibhedlela zinezidingo eziqinile mayelana nokuqhubeka nokuthembeka kokuphakelwa kukagesi.Isikhathi sokubuyisela ukunikezwa kwamandla okuzenzakalelayo kwezindawo ze-Class 0 yi-T≤15S, isikhathi sokubuyisela ukunikezwa kwamandla okuzenzakalelayo kwezindawo ze-Class 1 ngu-0.5S≤T≤15S, isikhathi sokubuyisela ukunikezwa kwamandla okuzenzakalelayo kwezindawo zekilasi lesi-2 ngu-T≤0.5S, futhi inani eliphelele lokuhlanekezelwa kwe-harmonic ye-voltage THDu ngu-≤3%.Imishini ye-X-ray, imishini ye-CT, kanye ne-nuclear magnetic resonance yonke imithwalo enokuqukethwe okuphezulu kakhulu kwe-harmonic.
10.Ithiyetha/Ijimu
I-Thyristor dimming system, imishini emikhulu ye-LED nokunye kuyimithombo ye-harmonic, inqubo yokusebenza izokhiqiza inombolo enkulu ye-harmonic yesithathu, hhayi nje kuphela ibangele uhlelo lokusabalalisa amandla okungasebenzi kahle kwemishini yamandla, kodwa futhi ibangele ukukhanya kwe-strobe, ukuxhumana, i-cable TV. kanye nomunye umsindo obuthakathaka wesekethe kagesi, futhi iveze nokwehluleka.
