Ukuze kuhlangatshezwane nezidingo zemikhumbi emikhulu nephakathi nendawo kanye nokuhlanganiswa komnotho emhlabeni wonke, kanye nezingqinamba zokuthuthukiswa komnotho nenhlalakahle ezinsizeni kanye nemvelo kanye nokuthuthukiswa kwempucuko yezemvelo emachwebeni asogwini, ukuthuthukiswa nokuklama kwamanzi ajulile. imizila nezindawo zokupaka, kanye nokwakhiwa kwemishini yokuthutha emachwebeni Enkulu futhi esebenza kahle kakhulu, ukuhlanganiswa kolwazi nokulawula ekuphathweni kwechweba, ukuthuthukiswa okuhlelekile okusekelwe kuzimpawu zezinhlobo ezahlukene zezimpahla, ezinkulu, ezihlakaniphile kanye nezinhlelo zemvelo yizo izici ezibalulekile zokuguqulwa kwesikhumulo sesikhathi esizayo kanye nokusungula izinto ezintsha.
Ngenxa yezidingo zokusabalalisa, kunenombolo enkulu yemithwalo ye-crane yendiza embonini yokulayisha njengamachweba, futhi ama-inverter afakwe emithwalweni eminingi.Inombolo enkulu yeziguquli zemvamisa ikhulisa kakhulu okuqukethwe kwe-harmonic ohlelweni lokusabalalisa amandla embonini yechweba.Njengamanje, inqubo yokulungiswa kwama-inverter amaningi isebenzisa ukulungiswa kwe-pulse eyisithupha ukuguqula amandla e-AC abe amandla e-DC, ngakho-ke ama-harmonics akhiqizwayo ikakhulukazi ama-harmonics esihlanu, esikhombisa, kanye neshumi nanye.Ukulimala kwama-harmonics kuhlelo lwe-petrochemical system kubonakaliswa ikakhulukazi ekulimaleni kobunjiniyela bamandla kanye nephutha lokulinganisa okunembile.Ucwaningo luye lwabonisa ukuthi imisinga ye-harmonic izodala ukulahlekelwa okwengeziwe ku-transformer, okuzobangela ukushisa ngokweqile, ukusheshisa ukuguga kwe-insulating medium, futhi kubangele ukulimala kokufakelwa.Ukuba khona kwama-harmonics kwandisa amandla abonakalayo futhi kunomthelela omubi kakhulu ekusebenzeni kahle kwe-transformer.Ngaphezu kwalokho, i-pulse current inomthelela omubi oqondile kuma-capacitor, ama-disconnectors kanye nemishini yokuvikela i-relay ohlelweni lokunikezwa kwamandla.Kumathuluzi amaningi okuhlola, impande yangempela yevelu yesikwele ayikwazi ukukalwa, kodwa inani elimaphakathi lingalinganiswa, bese i-waveform ecatshangwayo iphindaphindwa ngenkomba ephozithivu ukuze kutholwe inani lokufunda.Lapho ama-harmonics ebucayi, ukufundwa okunjalo kuzoba nokuphambuka okukhulu, okuholela ekuphambukeni kokulinganisa.
Izinkinga ongase uhlangane nazo?
1. Ukuqala izinkinga zama-cranes ahlukahlukene wezindiza namaphampu
2. I-converter ye-frequency ikhiqiza inani elikhulu lama-harmonics, elithinta ukusebenza okuphephile kwemishini kagesi yesistimu.
3. Ukujeziswa kwamandla asebenzayo okubangelwa isici samandla aphansi (ngokwesici samandla samanzi kanye nendlela yokulungisa imali kagesi eyakhiwe uMnyango Wezamanzi kanye Namandla Kagesi wenkampani yethu kanye Nophiko Lwezintengo lwenkampani yethu);
Isixazululo sethu:
1. Faka i-HD high-voltage esebenza ngamandla esinxephezelo esizenzakalelayo ohlangothini lwesistimu ye-6kV, 10kV noma 35kV ukuze unxephezele amandla asebenzayo esistimu, uthuthukise isici samandla, udizayine izinga lokusabela elisebenzayo, futhi ulawule ngokuzenzakalelayo ukushaya kwenhliziyo. yohlelo;
2. Uhlangothi lwamandla kagesi aphezulu lwesistimu lusebenzisa isistimu yokutakula okuguquguqukayo kwekhwalithi yamandla ukunxephezela ngamandla imithwalo esebenzayo ngesikhathi sangempela nokugcina ukuthembeka kwekhwalithi yamandla yesistimu;
3. Isihlungi esisebenzayo se-Hongyan APF sokulawula okuzenzakalelayo kwesistimu ye-pulse yamanje ifakwe ohlangothini olungezansi lwe-voltage 0.4kV, futhi imishini yesinxephezelo yokuphepha kwedatha ye-Hongyan TSF yohlelo lwesinxephezelo somthwalo osebenzayo ikhethiwe ukuze kuthuthukiswe isici samandla.
