Umatshini wonaka emva kokusebenza ixeshana.Siyintoni isizathu?Ngaba isiguquli rhoqo sinekhowudi yempazamo?Ukuba ewe, khangela incwadi yemigaqo.Uninzi lwazo lusebenza ngokugqithisileyo kwaye lunevoltage.Ukuba yinto eqhelekileyo, ukungqubuzana kwezixhobo ze-inverter ezipholile emoyeni kunokuba zikhulu kwaye ukuchasana kuya kuba kukhulu.Lungisa ixabiso langoku ngaphezulu kancinci okanye itorque kancinane.Musa ukulungelelanisa kakhulu ngexesha elinye, kuxhomekeke kumbane olinganisiweyo wemoto.Jonga ukuba isixhobo samandla aphezulu siqala na xa isiguquli samaza siyeka, okukhokelela kukungabikho kwamandla ombane.
Isisombululo kunye nohlalutyo lwesizathu:
Okokuqala, ixesha lokunciphisa isiguquli esijikelezayo sisetwa lifutshane kakhulu.Xa umguquli wefrequency erhuqa umthwalo omkhulu, ixesha layo lokunciphisa libekwe lincinci kakhulu.Ngexesha lenkqubo yokunciphisa isantya, ukuphuma rhoqo kwesiguquli sefrequency kwehla ngokukhawuleza, ngelixa inertia yomthwalo inkulu, nto leyo eyenza ukuba isantya semoto siphakame kunesantya esihambelana nokuphuma rhoqo kwesiguquli esijikelezayo, sisenza imotor ukuba ukuvelisa amandla ombane, oko kubangela ukuba i-voltage yekhonkco ye-DC embindini we-frequency converter ibephezulu kakhulu, ifikelele kwixabiso elilinganiselweyo kunye nokukhubeka, Ke ngoko, iziguquli ezinkulu zamaza ombane zixhotyiswe ngokubanzi ngeeyunithi zokusetyenzwa kwamagama.
Okwesibini, xa iinjini ezininzi ziqhuba umthwalo ofanayo, ngenxa yokuba akukho mthwalo usasazwayo, xa isantya sokwenyani semoto enye sidlula isantya sexesha lenye imoto, isantya esiphezulu silingana nomhambisi ohamba phambili, kwaye isantya esisezantsi silingana nesantya semoto. ijenereyitha, enokuthi ibangele impazamo yombane ogqithisileyo.
Okwesithathu, ngenxa yobomi be-capacitor yekhonkco eliphakathi le-DC ye-frequency converter, emva kweminyaka yokusetyenziswa, umthamo we-capacitor uyancipha, kunye nokukwazi ukulungiswa kwekhonkco le-DC eliphakathi kumbane we-DC liyehla, kunye namathuba okuhamba ngokugqithisileyo.Kwisicelo esisebenzayo, into yesibini ingaphezulu.Thatha isiguquli se-ladle trolley yesithando sokucoca i-rh njengomzekelo.Iqhutywa ziinjini ezimbini ezinomthwalo ofanayo.Ukungaphumeleli kwe-alam ye-overvoltage kaninzi kwenzeka ngexesha lokusebenza, kwaye i-converter efanayo ihlala i-alamu.Ngokuqwalasela, ixabiso le-voltage ye-DC ephakathi yekhonkco ye-converter iphezulu kwi-frequency ephezulu ngexesha lokusebenza.Ngohlalutyo, isantya sokwenyani semoto enye siphezulu kunesantya sokwenyani senye imoto, iyenza isebenze kwimeko yokuvelisa amandla, Kwaye ikhonkco leDC eliphakathi lisebenzisa le nxalenye yamandla kakuhle, nto leyo ekhokelela kumbane ogqithisileyo wombane. ikhonkco eliphakathi le-DC le-converter frequency, kunye nempazamo engaphezulu kwe-voltage ixeliwe.
