Umzekelo wokugcinwa kweadaptha yamandla

1, Umzekelo wokugcinwa kweadaptha yamandla elaptop ngaphandle kokuphuma kwamandla ombane

Xa i-laptop isetyenziswa, i-voltage iphakama ngokukhawuleza ngenxa yengxaki yombane wombane, obangela ukuba i-adapter yamandla iphele kwaye akukho mveliso yamandla.

Inkqubo yokugcinwa: i-adapter yamandla isebenzisa ukunikezelwa kwamandla okutshintsha, kunye noluhlu lwe-voltage yegalelo yi-100 ~ 240V. Ukuba i-voltage idlula i-240V, i-adapter yamandla inokutshiswa. Vula igobolondo yeplastiki ye-adapter yamandla kwaye ubone ukuba i-fuse iqhume, i-varistor itshise, kwaye enye yezikhonkwane itshiswe. Sebenzisa i-multimeter ukulinganisa ukuba isekethe yamandla inesekethe emfutshane ebonakalayo. Faka esikhundleni i-fuse kunye ne-varistor yenkcazo efanayo, kwaye udibanise i-adapter yamandla. Iadaptha yamandla isenokusebenza ngokuqhelekileyo. Ngale ndlela, ukhuseleko lwesekethe yonikezelo lwamandla kwi-adapter yamandla ilungile.

Ukususela kuhlalutyo lwangempela lwesiphaluka, i-varistor ixhunywe ngokuhambelana negalelo le-bridge rectifier diode. Umsebenzi wayo kukusebenzisa i-"Self Fusing" yayo kwimeko yokungena kombane ophezulu ngokukhawuleza, ukwenzela ukukhusela amanye amacandelo enxalenye ye-adapter yamandla kumonakalo ophezulu wombane.

Ngaphantsi kwemeko ye-voltage ye-220V eqhelekileyo yombane, ukuba akukho varistor yeenkcukacha ezifanayo esandleni, i-resistor ayikwazi ukufakwa kusetyenziso olungxamisekileyo.

Nangona kunjalo, kufuneka ifakwe ngokukhawuleza emva kokuthenga i-varistor. Kungenjalo, kuya kubakho ingxaki engapheliyo, ukusukela ekutshiseni amacandelo amaninzi kwiadaptha yamandla ukuya ekutshiseni ikhompyuter yencwadana.

Ukulungisa igobolondo yeplastiki edibeneyo ye-adapter yamandla, ungasebenzisa iglue ye-polyurethane ukuyilungisa. Ukuba akukho glu ye-polyurethane, ungasebenzisa iteyiphu yombane emnyama ukusongela izangqa ezininzi kwiqokobhe leplastiki yeadaptha yamandla.

2, Ukuba iadaptha yamandla iyancwina

I-adapter yamandla yenza isandi esikhulu "i-squeak" ngexesha lokusebenza, ephazamisana nomoya osebenzayo wabathengi.

Inkqubo yokugcinwa: phantsi kweemeko eziqhelekileyo, kuqhelekile ukuba i-adapter yamandla ibe nomsindo omncinci wokusebenza, kodwa ukuba ingxolo iyacaphukisa, yingxaki leyo. Ngenxa yokuba kwi-adapter yamandla, kuphela xa kukho i-gap enkulu ehambayo phakathi kwe-transformer yokutshintsha okanye i-ring magnetic ye-coil inductance kunye ne-coil, "i-squeak" iya kubangelwa. Emva kokususa i-adapter yamandla, hambisa ngobumnene inxalenye yeekhoyili kwii-inductors ezimbini ngesandla phantsi kwemeko yokungabikho kwamandla. Ukuba akukho mvakalelo yokukhululeka, kuqinisekileyo ukuba umthombo wengxolo yokusebenza yeadaptha yamandla uvela kwi-switching transformer.

Iindlela zokuphelisa isandi esithi "squeak" sokutshintsha i-transformer ngexesha lokusebenza zilandelayo:

(1) Sebenzisa intsimbi yokujongisa ngombane ukuphinda udibanise izikhonkwane zesolder phakathi kwezikhonkwane ezininzi zesiguquli sokutshintsha kunye nebhodi yesekethe eprintiweyo. Ngexesha le-welding, cinezela i-switch transformer ukuya kwibhodi yesiphaluka ngesandla ukwenza i-bottom ye-switch transformer ngokusondeleyo kwibhodi yesekethe.

(2) Faka ipleyiti yeplastiki efanelekileyo phakathi kondoqo wemagnethi kunye nekhoyili yesiguquli esitshintshayo okanye uyitywine ngeglue yepolyurethane.

(3) Beka iphepha eliqinileyo okanye iipleyiti zeplastiki phakathi kwe-switch transformer kunye nebhodi yesekethe.

Kulo mzekelo, indlela yokuqala ayinayo impembelelo, ngoko ke i-transformer yokutshintsha inokususwa kuphela kwibhodi yesiphaluka, kwaye isandi esithi "squeak" sipheliswa ngenye indlela.

Ngoko ke, xa kuthengwa i-adapter yamandla, kuyafuneka kwakhona ukulawula umgangatho we-transformer ye-adapter yamandla eveliswayo, enokuthi igcine ubuncinci bezinto eziphazamisayo!
