Kodwa-ke, amandla e-China okukhiqiza insimbi engahluziwe asangaphansi kwemikhawulo yenqubomgomo, futhi ngo-2008 akhuphukele kumkhiqizo wonyaka wamathani ayizigidi ezingama-660.Ngalesi sikhathi, i-tsunami yezezimali ebangelwa inkinga ye-British subprime mortgage crisis isisabalele emhlabeni wonke.Ngaphansi kokuhlanganiswa komnotho womhlaba, iChina nayo isengozini.Uhwebo lwangaphandle, izidingo zokutshalwa kwezimali, izindlu kanye nezinye izici zivinjelwe.Izinkampani zensimbi ziphakathi kwezimboni zokukhiqiza ezithintekayo kulokhu.
Ukuhlaziywa kwekhwalithi yamandla kanye nesistimu yokuphatha yohlelo lokusabalalisa amandla embonini yensimbi yensimbi nensimbi ikakhulukazi ifunda ukuqedwa kwesinxephezelo samandla asebenzayo kanye nezinkinga zokuphatha i-harmonic ohlelweni lokusabalalisa amandla.Imikhiqizo eyinhloko ihlanganisa isihlungi samandla asebenzayo, idivayisi yesinxephezelo samandla aphansi-voltage asebenzayo, ama-static var Generator, amadivaysi esinxephezelo esihlungi esishintshashintshayo se-hybrid, amadivaysi esinxephezelo se-hybrid dynamic attenuation, amadivayisi ahlakaniphile ashukumisayo esinxephezelo samandla asebenzayo, afanele abavikeli be-harmonic nezinye izinto zikagesi ekwakhiweni okusha. , ukwakhiwa kabusha, ukunwetshwa, kanye namaphrojekthi wokuguqulwa kwezobuchwepheshe ezimbonini, ezakhiweni zomphakathi nezomphakathi Isinxephezelo samandla asebenzayo, ukucindezelwa okuvumelanayo kanye nokuphathwa okuphelele, njll., ukunikeza izixazululo ezifanele zokuklama ngokwezinkinga zekhwalithi yamandla ezinhlobo ezahlukene zezimboni nezinhlobo zomthwalo, ezingathuthukisa ikhwalithi yokuphakelwa kukagesi kanye nokuqinisekisa ukusebenza okuphephile nokonga kwesistimu yamandla.
Imithwalo efana ne-DC extruder kanye ne-rectifiers ikhiqiza inani elikhulu lamanje le-harmonic ngesikhathi sokusebenza.Uma ingalawulwa, izophazamisa kakhulu ukusebenza okuphephile kwegridi yamandla nemithwalo ebucayi kugridi yamandla.Ngaphezu kwalokho, isici samandla semithwalo yesivinini esishintshashintshayo njengemishini ye-DC extrusion sisephansi kakhulu, futhi umthwalo osebenzayo ushintshashintsha kakhulu.Isinxephezelo samandla asebenzayo aphansi we-low-voltage (ikhabhinethi ye-capacitor) asikwazi ukufakwa ekusebenzeni okujwayelekile, ngoba asikwazi ukumelana nokuqeda umthelela we-pulse current, okuholela ekumoshweni okukhulu kwamandla kagesi.Ngisho noma ikhabhinethi ye-capacitor ingafakwa ekusebenzeni, kuyingozi kakhulu ukushisa i-fuse nokukhipha i-capacitor ngesikhathi esifushane.
Inani Lomsebenzisi Lesinxephezelo Samandla Asebenzayo Nokulawula Okuvumelanayo
Lungisa ama-harmonics, wehlise i-harmonic yamanje eyethulwe ohlelweni lwesofthiwe, futhi ucabangele amazinga embonini yenkampani yethu;
Isinxephezelo esiguqukayo samandla asebenzayo, isici samandla sifinyelela ezingeni elijwayelekile, ukugwema izinhlawulo ezivela ezinkampanini ezihlinzeka ngogesi;
Ngemuva kwesinxephezelo samandla asebenzayo, amandla wamanje wesofthiwe yesistimu ayancishiswa, futhi izinga lokusebenzisa umthamo we-transformer liyakhula.Ukonga amandla.
Izinkinga ongase uhlangane nazo?
1. Isici samandla aginqikayo semshini wokugaya oqondile wamanje siphansi kakhulu, umjikelezo wokusebenza mfushane, isivinini siyashesha, futhi ukushintshashintsha okungavumelekile kukhulu ngaphansi komthwalo womthelela.
2. I-DC rolling mill ayinayo kuphela into ephansi yamandla, kodwa futhi ikhiqiza ama-harmonics aphezulu, athinta ukusebenza okuvamile kwemishini kagesi.
Isixazululo sethu:
1. Khetha isiteshi sokuphepha sokuhlunga esicushwe kanye sohlelo lokuklanywa kwedivayisi yokuhlunga ye-Hongyan ukuze uhlunge ukuphuma kwe-pulse yamanje yesofthiwe yohlelo futhi unxephezele umthwalo osebenzayo ngesikhathi esifanayo;
2. Yamukela idivayisi yesinxephezelo sokuphepha esiguqukayo sase-Hongyan ukuze uhlangabezane nezimfuneko zesinxephezelo samandla asebenzayo anomthelela nokulawula okuvumelanayo.Lungiselela ngokunengqondo izinga lokusabela ngokuvumelana nezimo ze-harmonic zesistimu, unxephezele amandla asebenzayo esistimu, futhi wenze isici samandla sifinyelele ngaphezu kuka-0.95;
3. Sebenzisa isihlungi esisebenzayo se-Hongyan ukuze ulawule ama-harmonics ane-oda eliphezulu, futhi usebenzise idivayisi yesinxephezelo sokuphepha esinamandla ukuze unxephezele amandla asebenzayo esistimu, futhi amandla asebenzayo e-harmonic azofinyelela izinga ngemva kokufakwa ekusebenzeni;
4. Sebenzisa i-Hongyan TBB idivaysi ekhiqiza amandla engasebenzi ukuze unikeze amandla angasebenzi esigabeni ngasinye sohlelo, futhi uphathe i-harmonic ngayinye yesistimu.
