1 、 Kev saib xyuas piv txwv ntawm lub laptop fais fab adapter tsis muaj qhov hluav taws xob tso tawm
Thaum lub khoos phis tawj siv, qhov hluav taws xob tau nce dheev vim qhov teeb meem ntawm cov khoom siv hluav taws xob, ua rau lub hwj chim adapter hlawv tawm thiab tsis muaj hluav taws xob tso tawm.
Cov txheej txheem tu: lub hwj chim adapter siv lub zog hloov hluav taws xob, thiab cov khoom siv hluav taws xob yog 100 ~ 240V. Yog tias qhov hluav taws xob ntau tshaj 240V, lub hwj chim adapter yuav raug hlawv. Qhib lub plhaub yas ntawm lub hwj chim adapter thiab pom tias lub fuse tau tawg, lub varistor tau hlawv tawm, thiab ib qho ntawm cov pins tau raug hlawv. Siv ib lub multimeter los ntsuas seb lub hwj huam hluav taws xob puas muaj qhov luv luv luv. Hloov lub fuse thiab varistor ntawm tib qhov tshwj xeeb, thiab txuas lub hwj chim adapter. Lub hwj chim adapter tseem tuaj yeem ua haujlwm ib txwm. Nyob rau hauv txoj kev no, kev tiv thaiv hluav taws xob muab hluav taws xob hauv lub hwj chim adapter yog qhov zoo meej.
Los ntawm kev txheeb xyuas qhov tseeb hauv Circuit Court, lub varistor txuas nrog rau kev sib txuas nrog cov tswv yim ntawm tus choj rectifier diode. Nws txoj haujlwm yog siv nws "Self Fusing" nyob rau hauv cov ntaub ntawv ntawm instantaneous high voltage intrusion, thiaj li tiv thaiv lwm yam khoom ntawm ib feem ntawm lub hwj chim adapter los ntawm high voltage puas.
Nyob rau hauv cov xwm txheej ntawm ib txwm 220V fais fab mov voltage, yog tias tsis muaj varistor ntawm cov lus qhia zoo sib xws ntawm tes, lub resistor tsis tuaj yeem ntsia rau kev siv thaum muaj xwm ceev.
Txawm li cas los xij, nws yuav tsum tau nruab tam sim tom qab yuav lub varistor. Txwv tsis pub, yuav muaj teeb meem tsis kawg, xws li hlawv tawm ntau yam hauv lub hwj chim adapter mus hlawv tawm lub khoos phis tawj phau ntawv.
Txhawm rau kho lub plhaub yas disassembled ntawm lub hwj chim adapter, koj tuaj yeem siv polyurethane kua nplaum los kho nws. Yog tias tsis muaj cov kua nplaum polyurethane, koj tuaj yeem siv daim kab xev hluav taws xob dub los qhwv ob peb lub voj voog ncig lub plhaub yas ntawm lub hwj chim adapter.
2, Yuav ua li cas yog lub hwj chim adapter squeaks
Lub hwj chim adapter ua rau lub suab nrov "squeak" thaum lub sijhawm ua haujlwm, uas cuam tshuam rau kev khiav ntawm cov neeg siv khoom.
Cov txheej txheem tu: nyob rau hauv ib txwm muaj xwm txheej, nws yog ib txwm ua rau lub hwj chim adapter muaj suab nrov ua haujlwm me me, tab sis yog tias lub suab nrov nrov, qhov ntawd yog qhov teeb meem. Vim tias nyob rau hauv lub hwj chim adapter, tsuas yog thaum muaj qhov sib txawv loj ntawm qhov hloov pauv hloov pauv lossis lub nplhaib sib nqus ntawm inductance coil thiab lub kauj, "squeak" yuav tshwm sim. Tom qab tshem tawm lub hwj chim adapter, maj mam txav ib feem ntawm lub coils ntawm ob lub inductors los ntawm txhais tes nyob rau hauv qhov tsis muaj fais fab mov. Yog tias tsis muaj kev xav ntawm xoob, nws yog qhov tseeb tias lub suab nrov ua haujlwm ntawm lub hwj chim adapter los ntawm kev hloov pauv hloov pauv.
Cov txheej txheem los tshem tawm "squeak" suab ntawm kev hloov pauv hloov pauv thaum ua haujlwm yog raws li hauv qab no:
(1) Siv lub tshuab hluav taws xob hluav taws xob los rov txuas cov kev sib txuas ntawm cov pob qij txha ntawm ob peb tus pins ntawm qhov hloov pauv hloov thiab cov ntawv luam tawm. Thaum lub sij hawm vuam, nias lub hloov pauv hloov mus rau lub rooj tsav xwm hauv Circuit Court los ntawm tes ua rau hauv qab ntawm qhov hloov pauv hloov nyob rau hauv kev sib cuag nrog lub rooj tsav xwm Circuit Court.
(2) Ntxig ib lub phaj yas kom zoo nruab nrab ntawm cov tub ntxhais sib nqus thiab cov kauj ntawm lub tshuab hloov pauv lossis kaw nws nrog cov kua nplaum polyurethane.
(3) Muab cov ntawv tawv tawv lossis cov ntawv yas ntawm qhov hloov pauv hloov thiab lub rooj tsav xwm hauv Circuit Court.
Hauv qhov piv txwv no, thawj txoj kev tsis muaj txiaj ntsig, yog li lub tshuab hloov pauv tsuas tuaj yeem raug tshem tawm ntawm lub rooj tsav xwm Circuit Court, thiab lub suab "squeak" raug tshem tawm los ntawm lwm txoj kev.
Yog li ntawd, thaum yuav lub hwj chim adapter, nws tseem yuav tsum tau tswj qhov zoo ntawm cov khoom siv fais fab adapter transformer, uas tuaj yeem txuag tau ntau qhov tsis yooj yim!
