Phau Ntawv Qhia Txog Kev Siv Hluav Taws Xob Siab Hloov Cov Khoom Siv Hluav Taws Xob
Nrog rau txoj kev loj hlob ntawm cov cuab yeej siv hluav taws xob niaj hnub no, cov khoom siv hluav taws xob tau dhau los ua txoj hauv kev, yog li yuav tsum muaj kev xav tau ntau dua rau cov khoom siv hluav taws xob. Txawm hais tias cov khoom siv hluav taws xob tswj hwm ib txwm muaj kev ruaj ntseg zoo dua thiab siv tau zoo dua, lawv xav tau cov tshuab hloov pauv loj thiab hnyav thiab cov lim dej, ua rau nws nyuaj rau kev ua tau raws li qhov yuav tsum tau ua. Nyob rau ntawm lub sijhawm no, qhov zoo ntawm kev hloov hluav taws xob hloov pauv pib tshwm sim, vim nws tau siv rau hauv ntau qhov chaw nrog qhov zoo ntawm qhov me me, lub teeb yuag, thiab kev ua haujlwm siab. Rau kev tswj hwm thiab kev tiv thaiv ntawm cov khoom siv hluav taws xob hloov hluav taws xob, peb yuav tsum paub qee qhov kev paub txog lawv cov kev ua txhaum thiab kev saib xyuas kom ntseeg tau tias muaj kev ntseeg siab ntawm cov khoom siv hluav taws xob thaum siv.
Thawj qhov ua tau txhaum yog lub fuse hlawv lossis lub raj tawg ntawm cov khoom siv hluav taws xob. Peb txoj haujlwm txij nkawm yuav tsum ua raws li cov kauj ruam hauv qab no: ua ntej, peb yuav tsum tau tshawb xyuas qhov tseem ceeb xws li tus choj rectifier, diode, thiab cov lim dej loj. Yog tias tsis pom muaj teeb meem, tom qab ntawd tshawb xyuas qhov kev cuam tshuam cuam tshuam rau cov teeb meem.
Qhov thib ob ntawm kev ua txhaum yog tias lub fuse yog qhov qub, tab sis cov khoom siv hluav taws xob tseem tsis muaj qhov hluav taws xob tso tawm. Qhov no yog thaum peb yuav tsum xub ntsuas seb puas muaj qhov pib voltage. Yog tias qhov hluav taws xob xoom lossis qis heev, peb yuav tsum xyuas seb puas muaj cov khoom xau hauv tus pin pib, kom pom qhov tsis raug. Yog tias muaj qhov pib qhov hluav taws xob, nws muaj peev xwm ua rau muaj kev ua haujlwm tsis zoo hauv cov nti tswj lossis kev tiv thaiv Circuit Court. Lub sijhawm no, peb tuaj yeem tshawb xyuas ib leeg los txheeb xyuas qhov ua txhaum.
Qhov thib peb ntawm kev ua txhaum yog tias qhov hluav taws xob tso tawm los ntawm lub zog hluav taws xob siab dhau lawm. Yog vim li cas rau qhov tsis ua hauj lwm no feem ntau yog ib qho teeb meem nrog lub voltage regulator tswj Circuit Court, uas tej zaum yuav tshwm sim nyob rau hauv ib qho kev tivthaiv nyob rau hauv lub kaw Circuit Court, nrog rau optocouplers, tswj chips, thiab lwm yam. Qhov thib plaub yam txhaum yog raws nraim qhov opposite, uas yog hais tias tus voltage. cov zis los ntawm cov khoom siv hluav taws xob tsawg dhau, thiab muaj ntau yam laj thawj rau qhov xwm txheej no. Ib qho yog luv luv hauv Circuit Court; Qhov thib ob, qhov kev ua haujlwm ntawm lub raj hloov pauv tsis ua haujlwm, ua rau muaj kev nce ntxiv hauv cov khoom siv hluav taws xob sab hauv thiab txo qhov tso zis voltage; Thib peb, kev ua haujlwm tsis zoo ntawm 300V lim capacitor ua rau txo qis ntawm lub peev xwm ntawm lub zog; Plaub, muaj teeb meem nrog cov hloov pauv hloov pauv.
Feem ntau ntawm kev ua haujlwm tsis zoo, yog tias muaj teeb meem nrog lub raj hloov pauv, nws yog ib qho tsim nyog yuav tsum txiav tawm tam sim ntawd lub hwj chim mov, txwv tsis pub nws yuav yooj yim ua rau lub raj hloov hluav taws xob. Tom qab disconnecting lub hwj chim mov, peb yuav hloov lub hloov raj thiab ua lwm yam teeb meem.
Hauv qee qhov kev siv hluav taws xob siab, qhov poob ntawm kev hloov hluav taws xob yog qhov siab heev, uas tuaj yeem yooj yim ua rau overheating thiab tiv thaiv burnout. Rau qee qhov kev kho kom yooj yim, cov neeg ua haujlwm tu neeg ua haujlwm yuav tsum tau kho thiab kho qhov tsis raug. Txhawm rau daws cov teeb meem me me thiab teeb meem thaum siv, nws yog ib qho tseem ceeb heev uas yuav tsum paub qee qhov tsim nyog hauv Circuit Court thiab kev paub txog kev saib xyuas.
