Braking resistordhizaini, iyo yakakosha ndeyekurangarira iyo capacitor uye IGBT module voltage matambudziko, kudzivirira izvi zviviri zvakakosha zvishandiso neiyo yakakwira voltage yebhazi yakashambidzwa, idzi mbiri mhando dzezvikamu kana zvakaipa, inverter haigone kushanda zvakanaka.
Kuwedzera kune yakakura mitoro deceleration zviitiko zvinoda kuwedzera iyobraking resistoruye mabhureki chikwata kutsanya mabhureki, chaizvoizvo, kana maererano rinorema, kutanga-up nguva inodiwa chaizvo nokukurumidza mhando, vanodawo bhureki chikwata uye braking resistor kutanga, kare, ndakaedza kushandisa inverter kuti. dhiraivha yakakosha punching muchina, izvo zvinodikanwa zvenguva yekumhanyisa yeinverter inogadzirwa senge 0.1 masekonzi, kana yakazara-mutoro inotanga, kunyangwe mutoro wacho usingareme zvakanyanya, asi nekuti nguva yekumhanyisa ipfupi, kushanduka kwemagetsi ebhazi. ichave zvakare overvoltage kana overcurrent mamiriro. Asi nekuda kwekuti nguva yekumhanyisa ipfupi, iyo bhazi voltage fluctuation yakasimba kwazvo, pachava nepamusoro-voltage kana pamusoro-ikozvino, uyezve kuwedzera kunze braking unit uye braking resistor, inverter inogona kushanda zvakajairika.
Ongorora, nekuti nguva yekutanga ipfupi, iyo bhazi capacitor voltage inodururwa ipapo, uye inogadzirisa ipapo ine hombe yekuchaja mukati, zvichiita kuti magetsi ebhazi awedzere kukwira, saka kusimuka kwebhazi kusimba zvakanyanya, ipapo kunogona kunge kwadarika mazana manomwe. volts, pamwe chete nebraking resistor, unogona kubvisa kuchinja uku kwepamusoro-soro panguva yakakodzera, kuitira kuti frequency converter ishande mune yakajairika mamiriro.
