High zaus switching fais fab mov, dab tsi yog high zaus switching fais fab mov txhais tau tias
1. Kev Tshawb Fawb Txog Kev Txhim Kho ntawm DC Electroplating Fais Fab Kev Lag Luam
Electroplating yog cov txheej txheem ntawm kev hloov hluav taws xob hluav taws xob mus rau hauv lub zog tshuaj. Nyob rau hauv cov txheej txheem no, hlau ions tau txais electrons thiab raug txo rau hlau atoms. Cov hlau atoms tau npaj raws li qee txoj cai los tsim cov muaju thiab ua cov txheej txheem. DC electroplating fais fab mov muab "qhov chaw" ntawm electrons thiab lub zog rau crystallize hlau atoms. Yog li ntawd, lub luag haujlwm ntawm cov khoom siv hluav taws xob hauv cov txheej txheem electroplating yog qhov tseem ceeb heev.

Ua ntej nruab nrab -1960s, tib neeg siv AC-DC generators los muab DC fais fab rau electroplating. Thaum kho qhov tso zis ntawm DC lub tshuab hluav taws xob, qhov tso zis ntawm DC lub tshuab hluav taws xob yog siv los ua cov qauv ntsuas, thiab qhov ceev ntawm AC lub cev muaj zog hloov pauv hloov cov zis DC, uas yog hu ua "AC-DC-AC pawg. ". Vim nws txoj kev ntseeg siab, qhov system no ib zaug tau tswj hwm thaj tsam ntawm electroplating (tseem muaj cov khoom siv hluav taws xob hauv tib lub sijhawm, tab sis nws raug tshem tawm ua ntej.) Cov neeg tseem tuaj yeem pom nws hauv qee lub tsev loj hauv tsev. lawv ntxoov ntxoo. Txawm li cas los xij, qhov ua tau zoo ntawm cov kab ke no yog qhov tsawg heev, yog li nws thim rov qab los ntawm theem ntawm keeb kwm tsis ntev tom qab yug los ntawm lub zog hluav taws xob tshuab hluav taws xob. Peb hu rau DC fais fab mov system sawv cev los ntawm AC thiab DC generator teeb tsa thawj tiam ntawm DC electroplating fais fab mov.
Ua ntej lub hwj chim hluav taws xob tau sib txawv ntawm cov cuab yeej hluav taws xob, lub zog hluav taws xob silicon rectifiers tau siv dav hauv kev lag luam. Yog li ntawd, nyob rau hauv lub tshav pob ntawm electroplating, ib tug thiaj li hu ua "self-coupling plus silicon rectification" DC electroplating fais fab mov tshwm sim, uas yog, siv nws pib-coupling Lub transformer tswj lub AC voltage, thiab ces rectifies nws nrog ib tug high-power silicon. cev (pob). Txawm hais tias lub kaw lus no tau ua qee qhov kev nce qib piv nrog "AC-DC generator teeb" hauv thev naus laus zis, nws tsis yooj yim heev vim tias nws yuav tsum siv lub cev muaj zog lossis cov neeg ua haujlwm kom rub lub zog tswj qhov kawg ntawm autotransformer hauv kev tswj. Nyob rau tib lub sijhawm, nws qhov kev ua tau zoo tsis tau txhim kho, thiab nws cov precision thiab ripple kuj tsis zoo. Qhov no yog qhov thib ob tiam DC plating fais fab mov.
Nyob rau hauv nruab nrab mus rau lig 1950s, thyristor tau yug los nyob rau hauv Tswb Laboratories nyob rau hauv lub tebchaws United States. Yog li coj txoj moo zoo hloov pauv mus rau lub zog hluav taws xob kev lag luam xws li electroplating fais fab mov. Lub DC electroplating fais fab mov nrog thyristor raws li cov tub ntxhais tau tsim nyob rau hauv xws li keeb kwm yav dhau.
SCR electroplating fais fab mov feem ntau muaj ob daim ntawv hais txog cov qauv hauv Circuit Court: ib qho yog siv SCR los tswj qhov hluav taws xob ntawm thawj sab ntawm lub hwj chim zaus transformer, thiab tom qab ntawd siv silicon tube multi-phase rectification ntawm ob sab; lwm qhov yog siv ncaj qha SCR Voltage regulation thiab rectification yog ua nyob rau theem nrab ntawm lub hwj chim zaus transformer. Txawm li cas los xij, txoj cai tswj kev paub tab thiab kev tswj hwm yog siv rau kev tswj ntawm lub kaum sab xis ntawm lub thyristor los ntawm cov hluav taws xob hluav taws xob, kom cov khoom siv hluav taws xob ntawm thyristor electroplating fais fab mov yog zoo heev rau cov khoom yav dhau los. Nyob rau hauv cov kev ntsuas load, txaus siab qhov tseeb, ripple thiab efficiency yog feem ntau tau, tshwj xeeb tshaj yog nyob rau hauv efficiency, uas tau zoo heev ho piv nrog yav dhau los cov khoom, thiab lub hwj chim ntau kuj yog dav heev. Cov yam ntxwv zoo no ua rau nws dhau los ua lub ntsiab ntawm DC electroplating fais fab mov thaum nws tshwm sim. Txog tam sim no, cov khoom siv hluav taws xob zoo li no tseem siv tau ntau hauv Suav teb, thiab nws kuj yog siv rau hauv kev lag luam ntawm lub zog hluav taws xob ntau hauv cov teb chaws industrialized txawv teb chaws. Peb hu nws thib peb tiam DC electroplating fais fab mov.
Cov khoom siv hluav taws xob thib peb muaj qhov zoo tshaj plaws ntawm cov khoom dhau los, tab sis nrog kev txhim kho txuas ntxiv ntawm tib neeg cov kev xav tau rau txheej txheej zoo thiab kev tsim cov txheej txheem kev lag luam automation, nrog rau tib neeg lub zog txuag thiab txo cov pa phem hauv kev lag luam hauv kaum xyoo dhau los. , Qhov tsis zoo ntawm thyristor fais fab mov tau dhau los ua kom pom tseeb. Ua ntej tshaj plaws, nws tsuas tuaj yeem lav qhov ntsuas qhov tseeb hauv qee qhov kev thauj khoom, tab sis hauv kev tsim khoom tiag tiag, feem ntau ntawm cov xwm txheej tsis raug ntsuas, yog li nws feem ntau nyuaj kom ua tau raws li qhov tseeb tiag. Tib yam muaj tseeb rau ripple, uas tsuas yog txaus siab rau tus nqi ntsuas nyob rau hauv ib qho chaw (feem ntau ze rau tag nrho cov load). Tag nrho cov no ua rau nws nyuaj rau cov neeg siv nws los txhim kho cov txheej txheem zoo. Qhov thib ob, vim hais tias analog hluav taws xob Circuit Court yog siv los ua kom tiav cov theem-hloov tswj, thaum nws txuas nrog lub computer tswj system, qhov yuav tsum tau interface Circuit Court yog cumbersome thiab inconvenient. Tsis tas li ntawd, vim tsis muaj peev xwm tshem tawm ntawm lub zog zaus transformer, tag nrho lub tshuab yog loj, hnyav, siv tooj liab, thiab muaj kev cuam tshuam loj heev rau daim phiaj hluav taws xob. Nrog rau txoj kev loj hlob ntawm lub hwj chim electronics technology, high-frequency hwj chim conversion technology tau ntau thiab ntau lug siv. Qhov thib plaub tiam ntawm DC electroplating fais fab mov - siab zaus hloov fais fab mov tuaj rau hauv qab no.
