I-variable Frequency AC Drives 6.6kv 11kv 1000kW Medium Voltage VsD VfD

Incazelo emfushane:

Idrayivu kagesi emaphakathi iyidivayisi yamandla kagesi aphezulu, elawulwa yi-DSP, nge-SVPWM kanye neseli ochungechungeni lobuchwepheshe bamazinga amaningi ukuze kuqinisekiswe isiguquli ukuze sivumelane nezinkundla zezimboni.

Okuqukethwe kwe-harmonic kuncane kakhulu.Inesici samandla aphezulu kanye nekhwalithi enhle yokuphuma kwegagasi ngaphandle kokuhlunga okokufaka, idivayisi yesinxephezelo sesici samandla nesihlungi esiphumayo.Ukushisisa kwezimoto okubangelwa ama-harmonics ne-Torque ripple, umsindo, i-dv/dt, nezinkinga zamandla kagesi wemodi evamile nakho kuyagwenywa.Ilingana namamotho asynchronous kanye nama-synchronous.

Lo mkhiqizo waklonyeliswa njengemikhiqizo emisha eyinhloko kazwelonke ngo-2003, futhi wawusetshenziswe kabanzi ekulawuleni izimoto.

Isimiso sokusebenza

Isakhiwo se-JD-BP37/38 yochungechunge lwe-inverter yamandla aphezulu ihlanganisa isiguquli esishintshayo sesigaba, amaseli amandla kanye nesilawuli.

I-6kV series inverter iqukethe amaseli angu-5 isigaba ngasinye, amaseli angu-15 esewonke.
I-inverter yochungechunge lwe-10kV iqukethe amaseli angu-8 isigaba ngasinye, amaseli angu-24 esewonke.

Izakhiwo zamaseli amandla zivamile.Kuyi-AC -DC - AC single phase inverter circuit, ama-rectifier diode awesigaba sesithathu esigcwele igagasi, IGBT 23inverter ibhuloho elilawulwa ubuchwepheshe be-sinusoidal PWM.Iseli ngayinye yamandla iyafana, kulula ukuyithumela, ukugcina nokwenza okusele, uma kwenzeka ukwehluleka, amabhuloho akhuphukayo avuliwe ukuze kuzuzwe indlela yokudlula futhi okukhiphayo kwe-inverter kuyehla.
