Izinto omele uzazi malunga ne-resistors ze-braking

Jonga: 37 iimbono


I-resistor ye-Brakinguyilo, undoqo kukuqwalasela i-capacitor kunye neengxaki zemodyuli ye-IGBT, ukuphepha ezi zixhobo zibini ezibalulekileyo ngumbane ophezulu webhasi ehlanjwe, ezi ntlobo zimbini zamacandelo ukuba zimbi, i-inverter ayikwazi ukusebenza ngokufanelekileyo.

Ukongeza kwiziganeko zokunciphisa umthwalo omkhulu kufuneka zonyuseisixhasi isiqhoboshikunye neyunithi yokuqhobosha ukuya kunyathela ngokukhawuleza, eneneni, ukuba ihambelana nobunzima, ixesha lokuqalisa elifunekayo uhlobo olukhawulezayo, kufuneka kwakhona iyunithi yokuqhawula kunye ne-resistor yokuqhawula ukuqala, kwixesha elidlulileyo, ndazama ukusebenzisa inverter ukuba qhuba umatshini okhethekileyo wokubhobhoza, iimfuno zexesha lokukhawulezisa i-inverter yenzelwe njengemizuzwana eyi-0.1, xa umthwalo ogcweleyo uqala, nangona umthwalo awunzima kakhulu, kodwa ngenxa yokuba ixesha lokukhawuleza lifutshane kakhulu, ukuguquguquka kombane webhasi. iya kuba kwakhona overvoltage okanye overcurrent imeko. Kodwa ngenxa yokuba ixesha lokukhawulezisa lifutshane kakhulu, ukuguquguquka kwamandla ombane ebhasi kunamandla kakhulu, kuya kubakho i-voltage engaphezulu okanye ngaphezulu-yangoku, kwaye emva koko kwandiswe iyunithi yokunyathela yangaphandle kunye ne-resistor braking, i-inverter inokusebenza ngokuqhelekileyo.

Hlalutya, kuba ixesha lokuqalisa lifutshane kakhulu, amandla ombane we-bus capacitor acinywa ngoko nangoko, kwaye isilungisi ngoko nangoko sibe nokutshaja okukhulu kwangoku, okubangela ukuba umbane webhasi uphakame ngequbuliso, ngoko ke ukuguquguquka kwamandla ombane webhasi kunamandla kakhulu, ngoko nangoko kunokuba ngaphezulu kwama-700. iivolthi, ezidityaniswa neisixhasi isiqhoboshi, unokuphelisa oku kuguquguquka koxinzelelo oluphezulu ngexesha elifanelekileyo, ukwenzela ukuba i-converter frequency isebenze kwimeko eqhelekileyo.
