Kev hloov pauv zaus tsavyog ib qho khoom siv rau Ac tsav tsav.Nrog rau qhov tshwj xeeb topology, tswj kev ceev thiab lub zog los ntawm kev sib txawv ntawm qhov zaus ntawm cov khoom siv hluav taws xob.Nws yuav tswj lub cev muaj zog pib zoo heev.Vsdtuaj yeem siv rau hauv daim ntawv thov xws li me me kiv cua, twj tso kua mis daim ntawv thov mus rau loj compressor, conveying thiab hais txog.
Kev sib txawv zaus tsav yog siv nyob rau hauv ib tug tsav system muaj xws li Ac lub cev muaj zog, tsav tswj thiab ua hauj lwm interface.Ac lub cev muaj zog feem ntau yog peb theem los yog ib theem asynchronous thiab synchronous lub cev muaj zog.Cov maub los suav nrog peb ntu, tus choj hloov pauv hloov pauv, qhov txuas ncaj qha tam sim no, thiab peb theem inverter chav tsev.Voltage-source type vfd yog qhov feem ntau nyob deb.Lub rectifier converter yog configured li triple theem rau mem tes, tag nrho nthwv dej diode choj.Dc txuas muaj cov capacitors kom du lub Dc tso zis ripple thiab muab ib tug nruj input rau lub inverter.The tswj hom ntawm vfd feem ntau nrog rau V / F, SPWM, SVPWM .
Ntau qhov kho-ed ceev lub cev muaj zog load daim ntawv thov txuas ncaj qha mus rau peb theem fais fab mov tuaj yeem txuag hluav taws xob los ntawm kev siv vfd.Raws li kev txhim kho-ed loads raug lub cev muaj zog rau lub siab pib torque thiab tam sim no surges uas yog mus txog 8-10 npaug ntawm tag nrho-load tam sim no.Ac drives tuaj yeem maj mam nce lub cev muaj zog mus txog qhov ntsuas nrawm kom txo qis cov neeg kho tshuab thiab hluav taws xob kev ntxhov siab, txo tus nqi kho thiab loj dua lub neej ntawm lub cev muaj zog thiab cov khoom siv tsav.Qhov tam sim no kwv yees li 1.2 npaug ntawm lub cev muaj zog ntsuas ceev, txo qis tam sim no. .
Kev tswj cov txheej txheem thiab kev sib tham ntawm lub zog yog qhov laj thawj tseem ceeb rau kev siv zaus tsav.Xws li siv hauv lub twj tso kua mis.Thaum siv cov kev hloov ceev ceev, cov twj tso kua mis ua haujlwm tsis tu ncua ntawm qhov nrawm uas nce raws li qhov dej ntub dej nce ntxiv, uas phim qhov kev tawm ntawm qhov nruab nrab inflow.
Xi'an Noker Electric tau cog lus los muab cov neeg siv khoom ua tiav lub cev muaj zog pib tswj kev daws teeb meem, koj muaj teeb meem pib lub cev muaj zog, thov koj xav tiv tauj peb.Peb yuav muab cov kev daws teeb meem rau koj.
