Rau ntau hom vuam, ntau hom inverters yog siv: rau argon arc vuam, rau phau ntawv vuam, rau cov ntshav thiab semi-automatic txiav.
Inverter vuam yog ib qho kev txhim kho nquag siv uas ua kom ruaj khov combustion, tsis hais txog qhov hloov pauv tam sim no hauv lub ntsiab, thiab hluav taws xob yooj yim. Dab tsi yog qhov zais cia ntawm kev vwm vwm ntawm cov khoom siv inverter?
Inverter vuam guarantees tus du thiab zoo vuam. Lub tshuab vuam muaj xws li thaiv lub zog hluav taws xob, uas yog raws li MOSFET transistors thiab stabilization inductor, uas txo cov ripple ntawm rectified tam sim no. Hloov tam sim no yog nkag mus rau lub rectifier, tom qab uas lub inverter module hloov cov tam sim no ncaj qha mus rau high-frequency tam sim no, ces pub nws mus rau vuam transformer. Cov qauv tshwj xeeb ntawm cov cuab yeej ua rau nws tuaj yeem txo qhov hnyav ntawm transformer ob peb zaug, ua kom yooj yim dua thiab ntau dua hauv kev ua haujlwm. Thiab coj efficiency mus rau 90 feem pua.
Inverter vuam yog yooj yim indispensable rausiv hauv tsev, feem ntau nws yog siv rau hauv kev tsim kho, tsheb kho lub khw, thaum lub sij hawm installation ntawm lub teeb hlau lug. Txawm tias ib tug neeg uas tsis muaj kev kawm tshwj xeeb tuaj yeem ua haujlwm nrog cov cuab yeej zoo li no, nws tsuas yog txaus kom muaj kev paub dav dav thiab lub tswv yim txog kev vuam.
Inverter vuam: txiaj ntsig
- kev tswj tsis siv neeg ntawm vuam arc;
- nce kev tiv thaiv tiv thaiv hluav taws xob hloov pauv, du sine (zoo tam sim no);
- qhov ua tau zoo tshaj plaws, qhov hnyav tsawg kawg;
- tsis siv neeg nco txog kev siv vuam ntau zaus.
Txhua tus tswv yuav tsum muaj inverter vuam ntawm tes. Yog, nws yog qhov xav tau ntau zaus, txawm li cas los xij, muaj qee lub sijhawm uas koj tsuas ua tsis tau yam tsis muaj nws. Hmoov tsis zoo, koj yuav tsum tau them nyiaj ntau rau lub cuab yeej zoo. Muaj ib txoj hauv kev tawm - qhov no yog sib sau ua ke inverter ntaus ntawv nrog koj tus kheej txhais tes. Ua-nws-koj tus kheej inverter vuam yog muaj rau txhua tus.
Yog tias koj muaj lub siab xav me ntsis thiab muaj peev xwm nyeem thiab siv cov khoom siv hluav taws xob, peb tuaj yeem xav tias 50% ntawm cov haujlwm tau ua tiav lawm. Nyob rau hauv tus txheej txheem ntawm assembling inverter li, semiconductor qhov chaw yog siv: capacitors, transistors, diodes, thiab hais txog. Lub inverter ntaus ntawv muaj peb yam yooj yim modules: input rectifier; inverter module; tso zis rectifier. Lub tswv yim rectifier yog tsim los ntawm lub zog diodes ntawm kev tsim khoom hauv tsev (piv txwv li, DL 112). Tom ntej no, tus tsav tuaj rau hauv kev ua haujlwm, uas yog lub capacitor tsim rau qhov voltagetsis pub tsawg tshaj 300 V. Tom qab ntawd lub inverter module tuaj rau hauv kev ua haujlwm, uas muaj lub tshuab hluav taws xob ntau zaus, uas tsim cov unipolar lossis bipolar pulses. Qhov chaw ntawm cov cuab yeej ua haujlwm hauv qhov hnyav, yog li lawv tsim kom muaj cua sov ntau. Hauv qhov teeb meem no, nws yuav tsis yog superfluous xav txog kev siv lub tshuab cua txias thiab muaj zog radiators uas dissipate cov cua sov tsim. Txhua qhov kev sib txuas yuav tsum muaj kev ruaj ntseg, thiab rooj plaub nws tus kheej yuav tsum tau insulated.
Tam sim no, inverter vuam yog suav tias yog qhov zoo tshaj plaws vuam tshuab. Cov lus teb ntawm cov cuab yeej no feem ntau yog qhov zoo.
