Thaum kho kom zoo nkauj thiab tsim cov cables, koj kuj yuav tsum tau them sai sai rau qhov kev xaiv ntawm lub ntsiab fais fab hloov.Tom qab tag nrho, muaj ntau lub zog hloov pauv tseem ceeb, thiab lawv tau sib koom ua ke rau qhov sib txawv ntawm qhov sib txawv thiab lub zog tso zis.load yam ntxwv, thiab lwm yam Cov hauv qab no yog yuav ua li cas xaiv cov kev ua hauj lwm hom ntawm switching fais fab mov thiab switching fais fab mov.Nyob rau hauv tus txheej txheem ntawm kev xaiv ib tug switching fais fab mov, peb tuaj yeem xyuam xim rau cov teeb meem, thiab tom qab ntawd sim xaiv cov khoom siv hluav taws xob hloov hluav taws xob, thiab daim ntawv thov cov nyhuv yuav zoo dua.
Yuav ua li cas xaiv qhov hloov hluav taws xob.
Thaum xaiv cov khoom siv hluav taws xob hloov hluav taws xob, cov khoom siv hluav taws xob ntau, cov zis hluav taws xob nruab nrab, cov yam ntxwv ntawm kev thauj khoom, thiab kev ua haujlwm kub yuav tsum raug txiav txim siab.
1. Xaiv qhov tsim nyog input voltage ntau yam.Siv kev sib txuas lus ntaus ntawv ua piv txwv.Common input voltage specifications yog 110V thiab 220V, yog li muaj 110V.220V AC hloov dua siab tshiab thiab dav input voltage (AC: 85V-2**V).Tus qauv input voltage specification yuav tsum raug xaiv raws li qhov chaw thov.
2. Xaiv lub hwj chim tsim nyog.Cov khoom siv hluav taws xob hloov pauv siv ib feem ntawm cov zis hluav taws xob thaum lub sijhawm ua haujlwm thiab tso tawm raws li lub zog cua sov.Txhawm rau ua kom lub neej ua haujlwm zoo dua ntawm kev hloov hluav taws xob, nws tau thov kom xaiv cov khoom siv nrog lub zog ntsuas siab tshaj 30%.
3. Xav txog cov yam ntxwv ntawm kev thauj khoom.Txhawm rau txhim kho kev ruaj ntseg ntawm kev khiav hauj lwm zoo dua, nws tau thov kom hloov cov khoom siv hluav taws xob hauv kev ua haujlwm raws li kev thauj khoom ntawm 50% -80%, uas yog, piv txwv li cov khoom siv hluav taws xob ntau yog 20W, hloov hluav taws xob hloov nrog lub zog hluav taws xob. hwj chim ntawm 25W-40W yuav tsum tau xaiv.
Yog hais tias lub load yog lub cev muaj zog, lub teeb lub teeb los yog lub capacitor load, qhov tam sim no kuj loj heev thaum pib, thiab ib tug haum switching fais fab mov yuav tsum tau xaiv los tiv thaiv lub load.Yog hais tias lub load yog lub cev muaj zog, qhov voltage reversal ntawm shutdown yuav tsum tau txiav txim siab.
4. Tsis tas li ntawd, kev khiav hauj lwm kub ntawm cov khoom siv hluav taws xob hloov thiab seb puas muaj cov khoom siv cua txias ntau dhau yuav tsum tau txiav txim siab.Qhov ntsuas kub ntsuas hloov hluav taws xob nrog siab dhau lawm yuav tsum txo cov zis.Thov xa mus rau qhov txo qhov nkhaus ntawm qhov ntsuas kub ntsuas lub zog.
Lub tshuab hluav taws xob hloov hluav taws xob ua haujlwm yog dab tsi?
Ntau zaus.Pulse width tsau hom, zaus tsau.Pulse wide variable mode, zaus.Pulse dav variable hom.
1. Cov kev ua haujlwm qub feem ntau yog siv hauv DC / AC qhov sib txawv zaus fais fab mov lossis DC / DC voltage hloov dua siab tshiab;ob hom kev ua haujlwm tom kawg yog siv los hloov cov kev tswj fais fab.
2. Tsis tas li ntawd, qhov tso zis hluav taws xob ntawm cov khoom siv hluav taws xob hloov pauv kuj muaj peb hom kev ua haujlwm: txoj kev tawm hluav taws xob tam sim, qhov nruab nrab qhov hluav taws xob qhov hluav taws xob txoj kev, thiab qhov amplitude tus nqi tso tawm voltage txoj kev.
3. Nyob rau hauv tib txoj kev, txoj kev ua hauj lwm yav dhau los yog tsuas yog siv nyob rau hauv DC / AC hloov pauv zaus fais fab mov lossis DC / DC voltage hloov dua siab tshiab;ob txoj kev ua haujlwm tom kawg yog siv los hloov cov kev tswj fais fab.
Raws li hom kev sib txuas ntawm lub txee hloov pauv hauv kev tswj hwm, qhov hloov pauv hluav taws xob feem ntau tuaj yeem muab faib ua peb hom: series hloov hluav taws xob, sib txuas hloov hluav taws xob, thiab hloov hluav taws xob hloov hluav taws xob.Ntawm lawv, transformer switching fais fab mov (tom qab no hu ua transformer switching fais fab mov) kuj muab faib mus rau hauv: zawv zawg qhov rooj hom, semi-flat arm, tag nrho choj hom, thiab lwm yam .;raws li kev txhawb zog ntawm lub zog transformer thiab theem sib txawv ntawm qhov tso zis voltage, nws tuaj yeem muab faib ua: rau pem hauv ntej excitation, thim rov qab Excited, ib leeg-zoo siab, ob-excited;yog lub hom phiaj tseem ceeb muab faib ua ntau hom.
Cov ntsiab lus saum toj no yog yuav ua li cas xaiv hom kev ua haujlwm ntawm kev hloov hluav taws xob thiab hloov hluav taws xob.Thaum xaiv lub zog hloov pauv tseem ceeb, koj yuav tsum pom meej qhov ntsuas hluav taws xob thiab lub zog tsim nyog.Yog tias qhov hluav taws xob yog qhov siab, koj yuav tsum tau ua kom muaj peev xwm ntawm cov khoom siv no.Tsis tas li ntawd, qhov tseeb, qhov hloov hluav taws xob muaj ntau hom kev ua haujlwm, suav nrog cov zaus ruaj khov, mem tes dav, thiab lwm yam, yog li nws yuav tsum raug xaiv raws li qhov kev thov hauv tsev.
