Engineered rau 3 MW Drive Systems

Cov3750 kVA Qhuav Hom Transformeryog ib tug tshwj xeeb muaj peev xwm ntsuam xyuas, lub hom phiaj loj me me kom phim cov tswv yim yuav tsum tau ntawm3,000 kW (3 MW)Variable Frequency Drives (VFDs) lossis central solar inverters. Tsis zoo li cov qauv kev faib tawm uas pub cov khoom thauj tsis zoo xws li lub teeb thiab lub cev muaj zog, chav tsev no ua haujlwm tseem ceeb hauv kev hloov pauv hluav taws xob.

Peb txhais cov chav no ua ib qho tshwj xeebpowerformer qhuav hom transformer. Nws yog tsim los tsis yog kom txo qis voltage, tab sis kom cuam tshuam dynamically nrog cov tsis yog -linear hloov cov yam ntxwv ntawm rectifiers. Thaum tus qauv transformers yuav overheat vim qhov "taws" tam sim no waveforms kos los ntawm VFD, chav tsev no muaj cov tub ntxhais muaj zog thiab winding geometry tsim los tiv taus qhov siab - zaus kev ntxhov siab yam tsis muaj derating.

35kV Class Insulation Engineering

Txuas cov tsav loj ncaj qha mus rau sub- kab sib kis yuav tsum muaj kev tiv thaiv zoo. Raws li tus hwmhigh voltage qhuav hom transformer, tus qauv no feem ntau yog engineered rau thawj voltages ntawm33kV los yog 35kV.

Dielectric Clearance:Kev khiav hauj lwm ntawm 35kV nyob rau hauv qhuav- hom hom yuav tsum tau nthuav dav cua tshem tawm thiab cov txheej txheem tshwj xeeb resin casting. Peb siv aMuab ob npaug rau- txheej txheem Castrau HV coil kom paub meej tias qhov tsis muaj dab tsi -dawb dielectric barrier muaj peev xwm tiv taus qhov Basic Impulse Level (BIL) ntawm170 kV lossis 200 kV.
Kev tiv thaiv Surge:Txij li thaum siab -voltage nqus Circuit Court breakers tuaj yeem ua rau kev hloov hluav taws xob ntau dhau, HV windings tau ntxiv dag zog nrog kev tig ntxiv - mus rau -tig rwb thaiv tsev kom tiv thaiv kev ua tsis tiav thaum lub sijhawm hloov pauv.

Harmonic tshem tawm: Theem Shifting

Lub ntsiab lus tshwj xeeb ntawm 3750 kVA tsav transformer feem ntau yog nwsMulti-Winding Architecture.

Qhov teeb meem:Loj 6-pulse drives tsim qhov hnyav 5th thiab 7th harmonic tam sim no, uas cuam tshuam cov kab hluav taws xob.
Kev daws:Peb feem ntau tsim chav tsev no nrogob tug thib ob windingshloov los ntawm 30 hluav taws xob degrees (piv txwv li, Vector Groupd0y1 ib). Qhov no tsim 12-pulse system. Cov theem hloov ua rau qhov tseem ceeb ntawm kev sib haum xeeb los ntawm ob lub voj voog thib ob kom tshem tawm ib leeg tawm ntawm thawj sab. Qhov no "huv sab" cuam tshuam kom covhigh voltage qhuav hom transformerTsis muaj kuab paug rau cov kab hluav taws xob sab saud nrog cov suab nrov sib haum xeeb, ua raws li IEEE 519 tus qauv.

Cov ntsiab lus ntawm Daim Ntawv Thov

Hlau Rolling Mills:Pub 3 MW lub ntsiab tsav motors rau kub sawb mills. Cov theem- hloov qauv tsim tiv thaiv kev sib haum xeeb torque ripples hauv lub cev muaj zog.
Marine Propulsion:Siv nyob rau hauv lub nkoj nkoj hluav taws xob rau lub zog lub ntsiab azimuth thrusters (pods), qhov chaw qhuav - hom kev tsim kho yog qhov yuav tsum tau ua kom muaj kev nyab xeeb hluav taws.
Hnub ci PV cog:Txuas mus rau 3.X MW central inverters, nce 600V / 800V tiam mus rau 35kV sau daim phiaj.
