Ukuze kuhlangatyezwane neemfuno zeenqanawa ezinkulu kunye nobukhulu obuphakathi kunye nokuhlanganiswa koqoqosho lwehlabathi, kunye nemiqobo yophuhliso lwezoqoqosho nezentlalo kwimithombo kunye nokusingqongileyo kunye nophuhliso lwempucuko yendalo kumazibuko onxweme, uphuhliso kunye noyilo lwamanzi anzulu. iindlela kunye neendawo zokupaka, kunye noyilo koomatshini bothutho lwezibuko Ubungakanani obukhulu kunye nomgangatho ophezulu, ulwazi kunye nokuhlanganiswa kolawulo kulawulo lwezibuko, uphuhliso olucwangcisiweyo olusekwe kwiimpawu zeentlobo ezahlukeneyo zeempahla, ezinkulu, ezikrelekrele kunye neenkqubo zendalo. imiba ephambili yohlaziyo lwezibuko lwexesha elizayo kunye nokuyila.
Ngenxa yeemfuno zokusasazwa, kukho inani elikhulu lemithwalo ye-aviation crane kushishino lokulayisha olufana namachweba, kwaye ii-inverters zifakwe kwimithwalo emininzi.Inani elikhulu labaguquli beefrikhwensi linyusa kakhulu umxholo we-harmonic kwinkqubo yokuhambisa amandla kwishishini lezibuko.Okwangoku, inkqubo yokulungiswa kwezinto ezininzi eziguquguqukayo zisebenzisa i-mix-pulse rectification ukuguqula amandla e-AC kumandla e-DC, ngoko ke ii-harmonics eziveliswayo ikakhulu zi-harmonics yesihlanu, yesixhenxe, neyeshumi elinanye.Umonakalo we-harmonics kwi-software ye-petrochemical system ibonakaliswe ngokukodwa kwingozi yobunjineli bamandla kunye nephutha lokulinganisa ngokuchanekileyo.Uphononongo lubonise ukuba i-harmonic currents iya kubangela ilahleko eyongezelelweyo kwi-transformer, eya kubangela ukushisa, ukukhawuleza ukuguga kwe-insulating medium, kwaye kubangele umonakalo we-insulation.Ubukho be-harmonics kwandisa amandla abonakalayo kwaye kunempembelelo enkulu engalunganga ekusebenzeni kakuhle kwe-transformer.Ukongezelela, i-pulse current inefuthe elibi ngokuthe ngqo kwi-capacitors, i-disconnectors kunye nezixhobo zokukhusela i-relay kwinkqubo yokunikezelwa kwamandla.Kwizixhobo ezininzi zokuvavanya, ingcambu yokwenene ithetha ixabiso lesikwere alinakulinganiswa, kodwa ixabiso eliqhelekileyo linokulinganiswa, kwaye i-imaginary waveform iphindaphindwe ngesalathisi esilungileyo ukufumana ixabiso lokufunda.Xa i-harmonics inzulu, ufundo olunjalo luya kuba nokutenxa okukhulu, okukhokelela ekuphambukeni komlinganiselo.
Iingxaki onokudibana nazo?
1. Ukuqala iingxaki zeekhreyini ezahlukeneyo zeenqwelomoya kunye neepompo
2. I-frequency converter ivelisa inani elikhulu le-harmonics, elichaphazela ukusebenza okukhuselekileyo kwezixhobo zombane zenkqubo.
3. Isohlwayo samandla esisebenzayo esibangelwa sisibakala samandla aphantsi (ngokuhambelana nomba wamandla amanzi kunye nendlela yokulungelelanisa umrhumo oqulunqwe nguMphathiswa weMithombo yaManzi kunye noMbane woMbane wenkampani yethu kunye neBureau yeXabiso lenkampani yethu);
Isisombululo sethu:
1. Faka i-HD yezixhobo zembuyekezo ezizenzekelayo ze-high-voltage zamandla asebenzayo kwicala le-6kV, i-10kV okanye i-35kV yenkqubo ukuze ubuyekeze amandla asebenzayo enkqubo, uphucule umba wamandla, uyilo izinga lokusabela elisebenzayo, kwaye ulawule ngokuyinxenye ngokuzenzekelayo ipulse yangoku. yenkqubo;
2. Icala le-high-voltage yenkqubo isebenzisa inkqubo yokubuyisela umgangatho wamandla ukubuyisela ngokukhawuleza imithwalo esebenzayo ngexesha langempela kunye nokugcina ukuthembeka komgangatho wamandla wenkqubo;
3. Isihluzo esebenzayo Hongyan APF inkqubo yolawulo oluzenzekelayo inkqubo ipulse yangoku ifakwe kwicala lamandla ombane asezantsi 0.4kV, kunye nesixhobo sembuyekezo data static imbuyekezo Hongyan TSF inkqubo software imbuyekezo umthwalo reactive ikhethwa ukuphucula umba amandla.
