Txoj Cai Ua Haujlwm ntawm Inverter Vuam Tshuab
Lub inverter vuam tshuab feem ntau yog ib qho inverter arc vuam fais fab uas tsim los ntawm lub inverter, tseem hu ua arc vuam inverter. Nws yog ib yam tshiab ntawm vuam fais fab mov. Nws yog AC zog zaus (50Hz). Tig rau hauv DC, thiab tom qab ntawd siv cov khoom siv hluav taws xob siab hloov hluav taws xob (cov raj siv lead ua SCR, transistor GTR, teb -effect tube MOSFET lossis IGBT), hloov mus rau ob peb KHz ~ kaum ntawm KHz nruab nrab zaus AC lub zog, thiab tib lub sijhawm, lub transformer yog txo mus rau kaum ob ntawm welded kaum ob ntawm kaum V voltage, kho qhov tam sim no, thiab outputs ib tug kuj ruaj khov DC vuam tam sim no los ntawm cov hluav taws xob tiv thaiv-filtering tso zis.
Tag nrho txoj kev loj hlob ntawm lub tshuab inverter vuam yog tsim los ntawm kev muaj peev xwm loj, lub teeb yuag, kev ua haujlwm siab, kev hloov pauv, kev txhim kho ntse thiab lub hauv paus ntawm kev txhim kho kev ntseeg siab, kev ua haujlwm thiab kev nthuav dav. Nyob rau hauv tus txheej txheem ntawm kuj welding, txiav, thiab lwm yam txheej txheem. High -ffefiency thiab cov hluav taws xob siab ntom ntom ntom ntom yog ib qho ntawm cov hom phiaj tseem ceeb nrhiav kev ua haujlwm thoob ntiaj teb arc vuam inverter.
Lub hauv paus ntsiab lus ntawm lub tshuab inverter vuam yog raws li hauv qab no: peb-theem lossis ib-theem ua haujlwm zaus AC hluav taws xob yog siv los ua tiav tam sim no. Tom qab lim, tau txais ib qho hluav taws xob DC smoother. Lub inverter Circuit Court tsim los ntawm IGBT yuav tig DC hluav taws xob mus rau kaum ob KHz AC zog. Tom qab lub siab txo qis, qhov ruaj khov DC tso zis vuam tam sim no tau los ntawm kev lim dej rectification.
Vim lub siab ua hauj lwm zaus ntawm lub inverter, hlau-hearted cross-sectional cheeb tsam thiab coil lem ntawm lub ntsiab transformer yog heev txo. Yog li ntawd, lub tshuab inverter vuam tshuab tuaj yeem txuag tau cov ntaub ntawv hlau kom loj, txo qhov loj thiab qhov hnyav ntawm cov duab, thiab txo qis zog ntawm hluav taws xob. Ntau Nws yog ib qho tseem ceeb uas lub inverter vuam tshuab tuaj yeem kho cov zis tam sim no nyob rau lub sijhawm ntawm microsecond, yog li cov txheej txheem tswj zoo tshaj plaws uas yuav tsum tau ua los ntawm cov txheej txheem vuam tuaj yeem ua tiav, thiab cov txiaj ntsig zoo ntawm vuam tuaj yeem tau txais.
