I-Medium Voltage Frequency Drives 3kv 6kv 10kv KwiSigaba esiThathu seMoto yoMbane yeAc eFakelwe umfanekiso

Iidrive zeVolgeji eziPhakathi 3kv 6kv 10kv kwiSigaba esiThathu seMoto yoMbane yeAc

Inkcazelo emfutshane:

I-Medium voltage drive sisixhobo esiphezulu se-voltage, esilawulwa yi-DSP, kunye ne-SVPWM kunye neseli kwi-series multi-level technology ukuqinisekisa i-inverter ukuze ihambelane nemimandla yezoshishino.

Umxholo we-harmonic uncinci kakhulu.Inomgangatho ophezulu wamandla kunye nomgangatho olungileyo wemveliso ngaphandle kokucoca igalelo, isixhobo sembuyekezo yamandla kunye nesihluzo semveliso.Ukufudumeza kweMoto okubangelwa yi-harmonics kunye ne-Torque ripple, ingxolo, i-dv/dt, kunye neengxaki zombane wemowudi eqhelekileyo nazo ziyaphetshwa.Ilungele iimotor ezilinganayo kunye ne-synchronous.

Imveliso yawongwa njengeemveliso ezintsha eziphambili zesizwe ngo-2003, kwaye yayisetyenziswa ngokubanzi kulawulo lweemoto.

Umgaqo wokusebenza

Ubume be-JD-BP37/38 series inverter ephezulu yombane ibandakanya i-transformer yesigaba sokutshintsha, iiseli zamandla kunye nomlawuli.

I-6kV series inverter iqulethe iiseli ezi-5 kwisigaba ngasinye, iiseli ezili-15 zizonke.
I-10kV series inverter iqulethe iiseli ezi-8 kwisigaba ngasinye, iiseli ezingama-24 zizonke.

Izakhiwo zeeseli zamandla ziqhelekileyo.Yi-AC -DC - i-AC yesigaba esisodwa se-inverter sesekethe, i-diode yokubuyisela i-diode yesigaba esithathu esipheleleyo, i-IBBT 23inverter bridge elawulwa yiteknoloji ye-sinusoidal PWM.Iseli nganye yamandla iyafana, kulula ukuyigunyazisa, ukugcina nokwenza okushiyekileyo, ukuba kukho ukungaphumeleli, iibhulorho ezinyukayo ziya kufezekisa i-bypass kwaye imveliso ye-inverter iyancipha.
