Joang Variable Frequency Drive sebetsa?

Mokhanni oa maqhubu a feto-fetohangke sesebelisoa sa Ac motor drive.Ka topology e khethehileng, e laola lebelo le torque ka ho fetola maqhubu a matla a ho kenya letsoho.E tla laola motlakase ho qala hantle haholo.Vsde ka sebelisoa ts'ebetsong ho tloha ho fan e nyane, lisebelisoa tsa pompo ho isa ho compressor e kholoanyane, fetisa joalo-joalo.

Variable frequency drive e sebelisoa tsamaisong ea koloi e nang le Ac motor, drive controller le e sebetsang interface.Ac motor hangata e na le mekhahlelo e meraro kapa e le 'ngoe ea mohato oa asynchronous le synchronous motor.Molaoli o kenyelletsa likarolo tse tharo, sesebelisoa sa borokho sa rectifier, sehokelo sa hona joale se tobileng, le yuniti ea inverter ea mekhahlelo e meraro.Voltage-source type vfd ke eona e atileng haholo hole.Rectifier converter e hlophisitsoe e le triple phase six pulse, full wave diode bridge.Dc link e na le capacitor ho thereletsa Dc output ripple mme e fana ka tlhahiso e thata ho inverter.Mokhoa oa taolo oa vfd haholo o kenyelletsa V/F, SPWM, SVPWM. .

Lisebelisoa tse ngata tsa lebelo la lebelo la motlakase li hokahana ka kotloloho ho phepelo ea motlakase ea mekhahlelo e meraro li ka boloka matla ka ho sebelisa vfd.Joalo ka meroalo e lokisitsoeng e beha enjene ho torque e phahameng ea ho qala le maqhubu a hona joale a fihlang ho makhetlo a 8-10 ho feta moroalo o felletseng.Li-drive tsa Ac butle-butle li ka nyolla lebelo le lekantsoeng ho fokotsa khatello ea motlakase le ea motlakase, tsa fokotsa litšenyehelo tsa ho lokisa le ho eketsa bophelo ba lisebelisoa tsa motlakase. .

Taolo ea ts'ebetso le puisano ea matla ke mabaka a mantlha a ho sebelisa li-frequency drives.Joalo ka ho sebelisa pompo.Ha ho sebelisoa li-drive tsa lebelo tse fetotsoeng, lipompo li sebetsa ka mokhoa o tsoelang pele ka lebelo le ntseng le eketseha ha boemo ba seliba se metsi bo ntse bo eketseha, bo tsamaellanang le ho tsoa ha karolelano ea phallo.

Xi'an Noker Electric e ikemiselitse ho fa bareki litharollo tse felletseng tsa taolo ea makoloi, o na le mathata leha e le afe a ho qala koloi, ka kopo ikutloe u lokolohile ho ikopanya le rona.Re tla u fa litharollo tsa sistimi.
