Kwi-converter frequency, i-motor fast braking okanye ukumisa ngokuchanekileyo, ngokubanzi kusetyenziswa i-braking yamandla kunye ne-regenerative braking.Kwimowudi ye-braking yamandla, i-torque ye-braking efunwa yinkqubo ingaphantsi kwe-20% ye-torque elinganisiweyo ye-motor kunye ne-braking ayikhawulezi, akukho mfuneko yokumelana ne-braking yangaphandle, kwaye kuphela ilahleko yangaphakathi esebenzayo yemoto ingakwazi. yenza umda wombane wecala le-DC ngaphantsi kwexabiso lesenzo sokhuseleko olungaphezulu kwe-voltage.Ngokuchasene noko, kuyimfuneko ukukhetha isixhasi sokunyathela ukucima le nxalenye yamandla ahlaziywa yimoto.Ukuze uqonde ukunyanzeliswa kombane, icala le-DC le-inverter kufuneka lixhotyiswe ngesekethe yokubona i-voltage ukubona i-voltage ye-capacitor ukuze iqonde ukunyanzeliswa kwamandla.Izixhasi ze-Brakingzisetyenziswa ngokubanzi kwiimveliso ezahlukeneyo ze-elektroniki.
Xa i-braking kunye ne-resistor ye-braking yangaphandle, i-resistor yangaphandle kufuneka ikwazi ukufunxa i-80% yamandla ombane aguqulwa ngumthwalo wamandla anokubakho, apho i-20% inokuthi isetyenziswe nge-motor ngendlela yokutshatyalaliswa kobushushu, ngeli xesha ixabiso. of the resistor braking iba ncinane, nokuba motor ngokuphindaphindiweyo decelerated, ukukhethwaisixhasi isiqhoboshiamandla alinganisiwe ahlukile.Xa i-deceleration engapheliyo, i-resistor ye-braking ye-intermittent time (T-tS)> 600s.Ngokuqhelekileyo sebenzisa i-resistor duty duty eqhubekayo, xa i-braking intermittent, i-resistor evumelekileyo amandla iya kwandisa isicelo sokhetho oluchanekileyo lweyunithi yokunyathela i-resistor inokunciphisa ixesha lokumisa simahla lemithwalo enkulu ye-inertia ukufezekisa ukuyeka ngokukhawuleza okanye ukuyeka ngokuchanekileyo;inokuba kwisuntswana imithwalo yamandla ethotywayo ukuphumeza umsebenzi wokuhlaziya.
Abanye abathengi 'i-electrolysis workshop multifunctional unit design ayizange icinge ngokudibanisa i-inverterisixhasi isiqhoboshi, okubangelwa ixesha elide lokumisa simahla kunye nomgama omde wokutyibilika wemoto enkulu, ekhoyo yingozi efihlakeleyo yemveliso kunye nokusebenza;Kunzima ukuqaphela indawo echanekileyo yokubekwa kweetroli zesixhobo kunye neetroli ze-aluminiyam, ezichaphazela ukusebenza kakuhle.Emva kokufakwa kwe-resistors ye-braking, ezi ngxaki zingentla zisonjululwe.Nangona kunjalo, kufuneka kuqatshelwe ukuba, ekukhethweni kwe-resistor yokunyathela, kungekhona nje ukuqwalasela iimfuno zokhetho ngalunye lwe-inverter ye-braking resistor, kodwa kwakhona ngokweemfuno zolawulo lomsebenzisi kunye nokusetyenziswa kweendawo ezahlukeneyo, kufuneka kube ngesantya. , i-torque kunye nezinye imilinganiselo, kwaye emva koko ubale ukhetho oluchanekileyo lwe-resistor braking, ukuze ufezekise iimfuno zolawulo lomsebenzisi.
