Ekusetshenzisweni okungokoqobo kwesiguquli se-frequency, ezinye izinkinga ezingalindelekile zizovela ngezikhathi ezithile, ikakhulukazi ngenxa yokuthi abasebenzisi bezimoto abazi okuningi mayelana nobudlelwano obuhambisanayo phakathi kwesiguquli se-frequency kanye ne-motor, ikakhulukazi kwezinye izinhlelo zokusebenza zemoto ezikhethekile, izinkinga ezifanayo zigxila kakhulu. .
(1) Uma i-inverter isetshenziselwa ukulawula injini eshintsha isigxobo, kufanele kuqashelwe ngokukhethekile ukuhambisana nomthamo we-inverter, ukuze kuqinisekiswe ukuthi ukulinganisa kwamandla enjini ngaphansi kwezinombolo zezigxobo ezahlukene awekho ngaphezu kwesilinganiso okukhiphayo okwamanje okuvunyelwe yi-inverter, okungukuthi, i-current elinganisiwe ye-inverter ayikwazi ukuba ngaphansi kwe-motor elinganiselwe yegiya eliphezulu le-motor;Ngaphezu kwalokho, ukuguqulwa kwenombolo yesigxobo se-motor kufanele kwenziwe lapho injini iyeka ukusebenza, ukuze kuvinjwe ukusetshenziswa kabi kokuvikelwa kwe-overvoltage noma okungaphezulu.
(2) Isiguquli semvamisa esisetshenziselwa ukulawula ama-motor anesivinini esikhulu, ngoba i-torque yama-motor anesivinini esincane kakhulu, futhi ama-harmonics aphezulu azokwandisa inani lamanje.Ngakho-ke, lapho ukhetha i-converter ye-frequency, umthamo wesiguquli se-frequency kufanele ube mkhulu kune-motor evamile.
(3) Uma isithuthuthu esivikela ukuqhuma sifana nesiguquli sefrikhwensi, kufanele sihambisane nesiguquli esingaqhumi ngokuvumelana nesidingo sangempela, ngaphandle kwalokho kufanele sibekwe endaweni engeyona ingozi.
(4) Uma isiguquli semvamisa sisetshenziselwa ukulawula isilonda se-rotor motor, siyefana nokulawulwa kwemoto enesivinini esikhulu.Ngenxa yokuthi i-impedance yalolu hlobo lwenjini incane kakhulu, kufanele futhi ihambisane nesiguquli semvamisa esinomthamo omkhulu;Ngaphezu kwalokho, ngenxa yobuchwepheshe be-rotor yesilonda, isivinini ngemva kokuguqulwa kwemvamisa kufanele sihambisane nokubekezelelana kwemishini ye-motor rotor.
(5) Uma i-inverter isetshenziselwa ukulawula injini yepompo engaphansi kwamanzi, amandla amanje alinganisiwe alolu hlobo lwenjini makhulu kunalenjini evamile.Ngakho-ke, lapho ukhetha i-inverter, kubalulekile ukuqinisekisa ukuthi okwamanje okulinganiselwe okuvunyelwe yi-inverter kukhulu kune-motor, futhi akunakwenzeka ukumane ukhethe uhlobo ngokusho kwe-motor evamile.
(6) Ezimweni zokusebenza kwemoto enemithwalo eguquguqukayo, njengama-compressor namavibrator, lawo mamotho ngokuvamile anezidingo zesici sesevisi, okungukuthi, umthwalo kanye namandla emoto kukhulu kunenani eliphakeme lamandla ajwayelekile.Lapho kukhethwa isiguquli sefrikhwensi, ubudlelwano obufanayo phakathi kokuphumayo okulinganiselwe kwamanje kanye nenani eliphakeme kufanele kubhekwe ngokugcwele ukuze kuvinjelwe ukusetshenziswa kabi kwezenzo zokuvikela ngesikhathi sokusebenza.
(7) Uma isiguquli silawula i-synchronous motor, ngenxa yokuthi amandla e-synchronous motor ayalungiseka, amandla e-synchronous motor angaba mancane kunalawo enjini yokulawula imvamisa yamandla, ngokuvamile encishiswa ngo-10% kuya ku-20%.
Ngaphezu kokuqukethwe okungenhla, kungase kube namamotho anokunye ukusetshenziswa nezici.Lapho sikhetha isiguquli sefrikhwensi, kufanele sicabangele ngokugcwele izici zemoto nezimo zokusebenza, futhi sinqume amapharamitha wokuguqula imvamisa nokusebenziseka ngemva kokuhlola okuphelele.
