Thawj: Lub Teeb ntawm Cov Khoom Siv
Peb twb paub lawm tias lub luag haujlwm ntawm cov kua nplaum ntug thiab cov kua nplaum pob txha yog kho, yog li lawv ob leeg siv cov kua nplaum tawv, feem ntau yog cov kua nplaum epoxy. Cov kua nplaum epoxy feem ntau siv suav nrog ib qho khoom thiab ob qho khoom. Ib qho khoom hais txog tus neeg muag khoom ua ntej npaj lub cev nplaum thiab tus neeg sawv cev kho, feem ntau xav tau lub tub yees kom tiv thaiv kev kho ntawm chav tsev kub thiab txo nws cov kev ua tau zoo. Cov kua nplaum ob qho khoom muaj lub cev tseem ceeb ntawm cov kua nplaum thiab tus neeg sawv cev kho, uas tuaj yeem khaws cia ntawm chav tsev kub. Txawm li cas los xij, nws yuav tsum tau sib xyaw kom sib npaug raws li qhov sib piv tau teev tseg, txwv tsis pub nws yuav tsis qhuav zoo.
Ntau xyoo dhau los, tus nqi ntawm cov nplaum ib feem tau siab dua, thaum tus nqi ntawm cov nplaum ob feem qis dua. Ntau lub tuam txhab tsim khoom feem ntau siv cov nplaum ob feem vim yog kev txiav txim siab txog tus nqi, tab sis lawv feem ntau yuav ua rau tsis ua haujlwm vim yog qhov sib piv tsis raug lossis kev sib xyaw tsis sib xws. Nyob rau xyoo tas los no, tus nqi ntawm cov nplaum ib feem tau maj mam txo qis, thaum cov nplaum ob feem yuav luag poob lawv qhov zoo dua. Feem ntau cov tuam txhab tsim khoom feem ntau siv cov nplaum ib feem. Txawm li cas los xij, kev faib cov ncej ntug tau muab faib ua kev faib lub ntsej muag kawg thiab kev faib sib koom ua ke, thiab cov nplaum siv hauv ob txoj kev no txawv. Cov nplaum siv rau kev faib lub ntsej muag kawg yog siv rau qhov sib txuas ntawm lub hauv paus sib nqus, nrog rau qhov yuav tsum tau ua kom loj ntawm cov nplaum. Yog tias qhov loj ntawm cov nplaum yog ntxhib dhau, nws yog sib npaug rau kev nce qhov sib txawv ntawm huab cua ntawm lub transformer, ncaj qha cuam tshuam rau qhov inductance ntawm lub transformer.
Qhov thib ob, thaum siv cov nplaum rau ntawm qhov kawg, yuav tsum tau ua tib zoo saib xyuas qhov tawv ntawm cov kua nplaum. Lub plawv hlau nplaum uas muaj cov nplaum rau ntawm qhov kawg loj heev. Yog tias cov nplaum khov thiab muaj qhov tawv thiab kev ntxhov siab siab, nws yuav ua rau lub plawv hlau nplaum tawg. Yog li ntawd, nws yog qhov tsim nyog siv cov nplaum uas muaj qhov tawv nruab nrab. Rau kev faib cov kua nplaum ntawm qhov sib txuas ntawm cov ncej ntug, qhov yuav tsum tau ua rau cov kua nplaum nws tus kheej tsis siab heev. Txawm li cas los xij, yuav tsum tau ua tib zoo saib xyuas qhov puv ntawm cov nplaum ntug, txwv tsis pub nws tsis tuaj yeem tsim kev ntxhov siab zoo rau lub plawv hlau nplaum, thiab qhov inductance ntawm lub transformer yuav poob thaum lub sijhawm kub siab. Kev faib cov kua nplaum rau ntawm lub ncej nruab nrab yog kom txo qhov suab nrov, thiab siv cov kua nplaum mos. Nws yog qhov tsim nyog los tswj cov nyiaj faib kom tsim nyog. Yog tias muaj kua nplaum ntau dhau, nws tuaj yeem ua rau cov kua nplaum nthuav dav tom qab ci thiab cuam tshuam rau qhov inductance; Yog tias cov nyiaj faib me dhau, cov txiaj ntsig faib tsis tuaj yeem ua tiav. Hais txog kev siv tiag tiag, nws raug nquahu kom siv 2/3 txog 3/4 ntawm qhov ntim ntawm qhov sib txawv ntawm huab cua rau kev faib cov kem nruab nrab.
Feem ntau hais lus, cov chaw tsim khoom transformer xav tau cov nplaum ntug thiab cov nplaum nruab nrab ntau tshaj plaws, tab sis cov nplaum siv rau ob qho no sib txawv thiab yooj yim tsis meej pem. Yog li ntawd, nws yog qhov zoo tshaj plaws los siv ob xim kom paub qhov txawv ntawm lawv kom tsis txhob siv cov tsis raug. Kev faib khoom siv sab nraud feem ntau yog siv rau cov neeg siv khoom kawg kom txhaj cov nplaum rau hauv sab hauv ntawm lub transformer, thiab qhov yuav tsum tau ua tsawg heev. Cov nplaum mos feem ntau yog siv ua cov nplaum, uas tuaj yeem txo qhov rub ntawm lub zog sib nqus tom qab cov nplaum khov. Hom cua qhuav ntuj tuaj yeem siv los txo cov txheej txheem tsim khoom thiab tus nqi ntawm cov transformers. Nws yuav tsum tau sau tseg tias txhua cov nplaum yog cov tshuaj lom neeg thiab muaj cov kev cai txee lub neej. Cov khoom nplaum uas tshaj qhov txee lub neej yuav txo qis, thiab nws tsis pom zoo kom siv lawv dua.
Raws li rau tag nrho cov txheej txheem faib cov transformer, yog tias xav tau ci, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas qhov kub thiab lub sijhawm ntawm kev ci kom ntseeg tau tias cov kua nplaum tau kho tag nrho thiab ua tiav qhov txiaj ntsig siab tshaj plaws. Qhov kub ntawm cov kua nplaum ci ib txwm yog 100-120 ℃, thiab lub sijhawm yuav tsum tau tswj hwm hauv 0.5-1 teev.
