Icandelo.01 Intshayelelo kwii-capacitors zefilimu ze-DC-Link
Kwizicelo zamandla amatsha kunye nezithuthi zamandla amatsha, ii-capacitors zidlala indima ebalulekileyo kwiinkqubo ezinje ngolawulo lwamandla, ulawulo lwamandla kunye nokuguqulwa kwe-DC-AC.
Ingakumbi kwii-inverters, ii-capacitors zichaphazela ubomi kunye nokusebenza kwesiguquli.
I-inverter iqhagamshela umbane we-DC ngebhasi ye-DC ukuze yenze i-DC-Link.
Kule nkqubo, i-inverter ifumana umsinga we-pulse ovela kwi-DC-Link ize ivelise i-pulse voltage kuyo. Ezi volthi ziphezulu zinokubangela impembelelo kwizixhobo zombane.
Ii-capacitor ze-DC-Link ziphucula ukuthembeka kunye nobomi benkqubo ngokuguqula ukuguquguquka kwe-voltage, ukufunxa i-voltage ye-pulse kunye nokucoca ngempumelelo.
Kubalulekile ukukhetha i-capacitor yeDC-Link echanekileyo, engaphuculi nje kuphela uzinzo lwenkqubo yesiphelo, kodwa yandisa nobomi benkqubo.
Kwizicelo zamandla amatsha akhankanyiweyo apha ngasentla, ii-capacitors ze-DC-Link ziyinxalenye ebalulekileyo. Nokuba kwiinkqubo zokuvelisa amandla omoya, iinkqubo zokuvelisa amandla ze-photovoltaic okanye iinkqubo zezithuthi zamandla ezintsha, ukuthembeka okuphezulu kunye nobomi obude kuyafuneka, ngoko ke ukukhetha kwazo kubaluleke kakhulu.
Icandelo.02 Intshayelelo yeUthotho lwe-MDP lwe-YMIN DC-Link Film Capacitor
Ii-capacitor zefilimu ze-DC-Link ze-YMIN ze-MDP series zidlala indima ebalulekileyo kwicandelo lamandla amatsha, ingakumbi ekuveliseni amandla omoya, ekuveliseni amandla e-photovoltaic nakwiinkqubo zezithuthi zamandla amatsha. Zisebenza ngokuzinzileyo phantsi kweemeko zomthwalo ophezulu kunye nokuthembeka okuphezulu kunye nobomi obude.
Indima yothotho lwe-MDP kwiindawo ezahlukeneyo zesicelo
Icandelo.03 Iingenelo zothotho lwe-MDP njengee-capacitors ze-DC-Link
Xa kuthelekiswa nee-capacitors ze-aluminium electrolytic zemveli,Uthotho lwe-MDP lwe-YMINIi-capacitor zefilimu zisebenza ngcono ngokubhekiselele kumandla okumelana nombane, ukumelana nokuqhekeka, i-ESR ephantsi, njl. Ziphucula ukusebenza kakuhle kwenkqubo, zinciphisa ukulahleka kwamandla, zonyusa uzinzo, kwaye zifanelekile kakhulu ukusetyenziswa kwizicelo zamandla amatsha.
Isishwankathelo seCandelo.04
Kwizicelo zamandla amatsha kunye nezithuthi zamandla amatsha, ii-capacitors ze-DC-Link zizinto ezibalulekileyo, ngakumbi kwiinkqubo ze-inverter, apho ukuguquguquka kwe-voltage egudileyo kunye ne-pulse voltages ezifunxayo zibalulekile ekuphuculeni ukuthembeka kwenkqubo kunye nobomi bayo.
Ii-capacitor zefilimu ze-DC-Link ze-YMIN MDP series zilukhetho olufanelekileyo kwicandelo elitsha lamandla ngenxa ye-voltage yazo ephezulu yokumelana, ubomi obude, kunye ne-ESR ephantsi. Xa kuthelekiswa nee-capacitor ze-aluminium electrolytic zemveli, uthotho lwe-MDP lunozinzo oluqinileyo lwenkqubo kwaye luyinxalenye ebalulekileyo yokuphucula ukusebenza kakuhle kweenkqubo ezintsha zamandla kunye nokwandisa ubomi bezixhobo.
