Kodi Variable Frequency Drive amagwira ntchito bwanji?

A frequency drive drivendi chipangizo cha Ac motor drive.Ndi topology yapadera, imawongolera liwiro ndi torque posintha kuchuluka kwamagetsi olowera. Imawongolera kuyendetsa bwino kwamagalimoto.VsdItha kugwiritsidwa ntchito kuyambira kufanizira yaying'ono, makina opopera mpaka kompresa wamkulu, kutumiza ndi zina zotero.

Kuyendetsa pafupipafupi kumagwiritsidwa ntchito mumayendedwe opangidwa ndi Ac motor, chowongolera choyendetsa ndikugwiritsa ntchito mawonekedwe.Ac motor nthawi zambiri imakhala ndi gawo limodzi kapena gawo limodzi lofanana ndi mota ya synchronous.Wowongolera kuphatikiza magawo atatu, chosinthira mlatho wokonzanso, ulalo wachindunji, ndi gawo la inverter la magawo atatu.Voltage-source vfd ndiyomwe imapezeka kwambiri kutali.The rectifier converter imakonzedwa ngati katatu gawo lachisanu ndi chimodzi pulse, full wave diode bridge.Dc link imakhala ndi capacitor kuti ikhale yosalala ya Dc ripple ndipo imapereka kulowetsa kolimba kwa inverter.Mawonekedwe olamulira a vfd makamaka V/F, SPWM, SVPWM .

Mapulogalamu ambiri othamanga othamanga amalumikizana mwachindunji ndi magawo atatu amagetsi amatha kusunga mphamvu pogwiritsa ntchito vfd.Monga katundu wokhazikika amaika injini pa torque yayikulu yoyambira komanso mafunde apano omwe amakhala mpaka 8-10 kuchulukitsa kuchuluka kwapano.Magalimoto a Ac amatha kukwezera motere mpaka liwiro lovotera kuti achepetse kupsinjika kwamakina ndi magetsi, kuchepetsa mtengo wokonza komanso kukulitsa moyo wagalimoto ndi zida zoyendetsedwa. Zomwe zikuchitika pafupifupi nthawi 1.2 za liwiro la mota, zimatsitsa mwachangu ma inrush pano. .

Kuwongolera njira ndi kukambirana kwamphamvu ndiye zifukwa zazikulu zogwiritsira ntchito ma frequency drive.Monga kugwiritsa ntchito pompo.Mayendedwe othamanga akagwiritsidwa ntchito, mapampuwa amagwira ntchito mosalekeza pa liwiro lomwe limawonjezeka pamene chitsime chonyowa chikuwonjezeka, chomwe chimagwirizana ndi kutuluka kwapakati.

Xi'an Noker Electric yadzipereka kupatsa makasitomala mayankho athunthu oyambira oyambira, muli ndi vuto lililonse loyambira pamagalimoto, chonde omasuka kulankhula nafe.Tidzakupatsani mayankho adongosolo.
