Variable Frequency AC Drives 6.6kv 11kv 1000kW Medium Voltage VsD VfD

Tlhaloso e Khutšoanyane:

Medium voltage drive ke sesebelisoa sa motlakase o phahameng haholo, se laoloang ke DSP, ka SVPWM le cell in series ea multi-level technology ho netefatsa inverter hore e lumellane le masimo a indasteri.

Likahare tsa harmonic li nyane haholo.E na le matla a phahameng a matla le boleng bo botle ba wave wave ntle le li-filters tse kentsoeng, sesebelisoa sa puseletso ea matla le sefahla sa tlhahiso.Ho futhumatsa motlakase ho bakoang ke li-harmonics le Torque ripple, lerata, dv/dt, le mathata a motlakase a tloaelehileng le tsona lia qojoa.E lumellana le li-motors tsa asynchronous le synchronous.

Sehlahisoa sena se ile sa abeloa e le lihlahisoa tse ncha tsa naha ka 2003, 'me se ne se sebelisitsoe haholo taolong ea makoloi.
