Ngokusetyenziswa ngokubanzi kwesantya esiguquguqukayo sokuqhuba, i-servo, i-ups kunye nezinye iimveliso, inani elikhulu lee-harmonics livele kwigridi yamandla, kwaye ii-harmonics zizise iingxaki ezinkulu kakhulu zomgangatho wamandla.Ukuze kulungiswe ingxaki ye-harmonic kwigridi yamandla, inkampani yethu iphuhlise inqanaba lesithathuisihluzo esisebenzayoisekelwe kwimigangatho emibini esebenzayo yokucoca.
Isihluzi se-harmonic esisebenzayoinokusetyenziswa ngokubanzi kwimizi-mveliso, yorhwebo kunye nothungelwano losasazo lweziko, njengale: iinkqubo zamandla, amashishini e-electrolytic plating, izixhobo zokucocwa kwamanzi, amashishini epetrochemical, iivenkile ezinkulu zokuthenga kunye nezakhiwo zeofisi, amashishini achanekileyo ombane, isikhululo seenqwelomoya/izibuko, amaziko onyango. , njl. Ngokwezinto ezahlukeneyo zesicelo, ukusetyenziswa kweisihluzo samandla asebenzayoiya kudlala indima ekuqinisekiseni ukuthembeka konikezelo lwamandla, ukunciphisa ukuphazamiseka, ukuphucula umgangatho wemveliso, ukwandisa ubomi bezixhobo kunye nokunciphisa umonakalo wezixhobo.
I-harmonic ye-3 kumashishini amaninzi e-semiconductor inzima kakhulu, ngokukodwa ngenxa yenani elikhulu lezixhobo zokulungiswa kwesigaba esisodwa ezisetyenziswa kumashishini.I-harmonic yesithathu yeye-zero yolandelelwano lwe-harmonics, eneempawu zokuqokelela kumgca ongathathi hlangothi, okukhokelela kuxinzelelo olugqithisileyo kumgca ongathathi hlangothi, kunye nesiganeko sokutshisa, esinobungozi obukhulu obufihliweyo kukhuseleko lwemveliso.IiHarmonics zinokubangela ukuba abaphuli beesekethe bahambe, balibazise ixesha lokuvelisa.I-harmonic yesithathu yenza ukujikeleza kwi-transformer kwaye ikhawuleza ukuguga kwe-transformer.Ukungcoliseka okunzulu kwe-harmonic kuya kuchaphazela ngokuqinisekileyo ukusebenza kakuhle kwenkonzo kunye nobomi besixhobo kwinkqubo yokuhambisa amandla.
Uninzi lwamakhonkco okulungiswa kwe-inverter kukusetyenziswa kwee-pulses ezi-6 ukuguqula i-AC kwi-DC, ngoko ke i-harmonics eveliswayo ngokuyininzi i-5, 7, 11 amaxesha.Iingozi zayo eziphambili ziingozi kwizixhobo zamandla kunye nokutenxa kumlinganiselo.Ukusetyenziswa kweisihluzo esisebenzayoingaba sisisombululo esilungileyo kule ngxaki.
Ukusetyenziswa kwei-harmonic esebenzayoisihluzi:
1. Ukucoca i-harmonics yangoku, enokuthi ihluze ngokufanelekileyo i-harmonics yamaxesha angama-2-25 kumthwalo wangoku, ukwenzela ukuba inethiwekhi yokusabalalisa icoceke kwaye isebenze kakuhle, kwaye ihlangabezane neemfuno zomgangatho wesizwe wokuqhawula inethiwekhi yokusabalalisa.Isihluzi esisebenzayo siguquguquka ngokwenene imbuyekezo yokulandela umkhondo, inokuchonga ngokuzenzekelayo utshintsho olupheleleyo lomthwalo kunye nokutshintsha komxholo we-harmonic kunye nokulandelela ngokukhawuleza imbuyekezo, impendulo ye-80us kutshintsho lomthwalo, i-20ms ukufumana imbuyekezo yokulandelela ngokupheleleyo.
2. Ukuphucula ukungalingani kwenkqubo, kunokuphelisa ngokupheleleyo ukungalingani kwenkqubo okubangelwa yi-harmonics, kwimeko yeemvume zezixhobo zokusebenza, kunokusetwa ngokutsho komsebenzisi ukubuyisela inkqubo ulandelelwano olusisiseko olubi kunye namacandelo okungalingani okulandelelana kunye nembuyekezo ephakathi amandla asebenzayo.
3. Ukuthintela i-resonance yegridi yamandla, engayi kuhambelana negridi yamandla, kwaye inokulinganisa ngokufanelekileyo i-resonance yegridi yamandla ngokwayo ngaphakathi kwendawo yomthamo wayo.
4. Iindidi zemisebenzi yokukhusela, kunye ngaphaya kwangoku, ngaphezulu kwe-voltage, phantsi kwe-voltage, ukushisa okuphezulu, impazamo yesiphaluka sokulinganisa, ukubetha kombane kunye neminye imisebenzi yokukhusela.
5. Ukusebenza okupheleleyo kwedijithali, kunye ne-interface ye-man-machine enobungane, okwenza umsebenzi ube lula, kulula ukuwusebenzisa kunye nokugcina.
