Idrayivu yefrikhwensi eguquguqukayoiyidivayisi ye-Ac motor drive.Nge-topology ekhethekile, ilawula isivinini kanye ne-torque ngokushintsha imvamisa yokunikezwa kwamandla okokufaka.Izolawula ukuqala kwenjini ngokushelela kakhulu.Vsdingasetshenziswa ekusetshenzisweni kusukela ku-fan encane, izinhlelo zokusebenza zepompo ukuya kwi-compressor enkulu, ukudlulisa nokunye.
I-variable frequency drive isetshenziswa ohlelweni lokushayela oluhlanganisa i-Ac motor, isilawuli sedrayivu kanye nesixhumi esibonakalayo.Injini ye-Ac ivamise ukuba yizigaba ezintathu noma isigaba esisodwa se-asynchronous kanye ne-synchronous motor.Isilawuli esifaka izingxenye ezintathu, isiguquli sebhuloho esilungisa kabusha, isixhumanisi esiqondile samanje, kanye neyunithi yokuguqula izigaba ezintathu.Uhlobo lomthombo we-voltage i-vfd yilona oluvame kakhulu ezindaweni ezikude.Isiguquli se-rectifier silungiselelwe njenge-pulse yesigaba sesithupha se-triple, i-wave wave diode bridge.Isixhumanisi se-Dc siqukethe ama-capacitor ukuze bushelelezi i-Dc ripple ephumayo futhi inikeza okokufaka okuqinile ku-inverter.Imodi yokulawula ye-vfd ikakhulukazi ehlanganisa i-V/F, i-SPWM, i-SVPWM .
Izinhlelo zokusebenza eziningi ezilayisha isivinini esilungisiwe zixhuma ngqo kugesi wezigaba ezintathu zingonga amandla ngokusebenzisa i-vfd.Njengoba imithwalo engashintshile ibeka injini ku-torque ephezulu yokuqala kanye nokunyuka kwamanje okungafika izikhathi ezingu-8-10 kunomthwalo ogcwele wamanje.Amadrayivu e-Ac angase anyuse kancane kancane injini ifinyelele kwisivinini esilinganiselwe ukuze kwehliswe ukucindezelwa komshini nokagesi, kwehlise izindleko zokukhanda futhi kukhulise impilo yemoto nezisetshenziswa ezishayelwa. Isimanje izikhathi ezingaba ngu-1.2 zesivinini esilinganiselwe senjini, sehlise ngokushesha amandla akhona. .
Ukulawula inqubo kanye nengxoxo yamandla yizona zizathu eziyinhloko zokusebenzisa amadrayivu efrikhwensi.Njengokusebenzisa empompini.Lapho kusetshenziswa amadrayivu esivinini alungisiwe, amaphampu asebenza ngokuqhubekayo ngesivinini esikhuphukayo njengoba izinga lomthombo omanzi likhuphuka, elifana nokuphuma kokungena okumaphakathi.
I-Xi'an Noker Electric izibophezele ekuhlinzekeni amakhasimende ngezixazululo eziphelele zokulawula ukuqalisa imoto, unezinkinga zokuqalisa imoto, sicela ukhululeke ukuxhumana nathi.Sizokunikeza izixazululo zesistimu.
