Inoshanda sei Variable Frequency Drive?

A variable frequency drivemudziyo weAc motor drive.Iine yakakosha topology, inodzora kumhanya uye torque nekusiyanisa frequency yekuisa magetsi magetsi.Inodzora mota kutanga zvakanaka.Vsdinogona kushandiswa mukushandisa kubva kudiki feni, pombi yekushandisa kune yakakura compressor, fambisa uye zvichingodaro.

Variable frequency drive inoshandiswa mudhiraivha system ine Ac motor, drive controller uye inoshanda interface.Ac mota inowanzoita matatu chikamu kana chimwe chikamu asynchronous uye synchronous mota.Iyo controller inosanganisira zvikamu zvitatu, rectifier bhiriji inoshandura, yakananga ikozvino chinongedzo, uye matatu chikamu inverter unit.Voltage-source type vfd ndiyo inonyanya kuwanikwa kure.Iyo rectifier inoshandura inogadziriswa senhatu nhanho yechitanhatu pulse, yakazara wave diode bhiriji.Dc link ine capacitor kutsvedza iyo Dc inobuda ripple uye inopa kuomarara kupinza kune inverter.Iyo control mode yevfd kazhinji inosanganisira V/F, SPWM, SVPWM. .

Mazhinji anogadzirisa-ed anomhanyisa mota kurodha maapplication anobatana zvakananga kune matatu echikamu magetsi anogona kuchengetedza simba nekushandisa vfd.Sezvo mitoro yakagadziriswa inoisa mota kune yakakwira yekutanga torque uye ikozvino masurges anosvika 8-10 nguva iyo yakazara-mutoro ikozvino.Madhiraivha eAc anogona kukwidza mota zvishoma nezvishoma kusvika pakumhanya kwakayerwa kuderedza kusimba kwemagetsi nemagetsi, kuderedza mutengo wekugadzirisa uye kuwedzera hupenyu hwemotor nemidziyo inotyairwa. Yazvino inokwana ka1.2 yemotor yakayerwa kumhanya, nekukurumidza kuderedza inrush ikozvino. .

Kudzora kwemaitiro uye kutaurirana kwesimba ndizvo zvikonzero zvikuru zvekushandisa frequency drives.Zvakadai sekushandisa mupombi.Kana yakagadziridzwa madhiraivha ekumhanya anoshandiswa, mapombi anoshanda achienderera nekumhanya kunowedzera sezvo tsime remvura rinowedzera, rinoenderana nekubuda kweavhareji yekupinda.

Xi'an Noker Electric yakazvipira kupa vatengi vane yakazara mota yekutanga kutonga mhinduro, iwe une chero mota yekutanga matambudziko, ndapota inzwa wakasununguka kutibata.Isu tichakupa iwe sarudzo dzehurongwa.
