Isibonelo sokulungisa i-adaptha yamandla

1, Isibonelo sokugcinwa kwe-adaptha yamandla ekhompuyutha ngaphandle kokuphuma kwamandla kagesi

Lapho i-laptop isetshenziswa, i-voltage ikhuphuka ngokuzumayo ngenxa yenkinga yolayini wokuphakela amandla, okubangela ukuthi i-adaptha yamandla iphele futhi kungabikho okukhipha ugesi.

Inqubo yokulungisa: i-adaptha yamandla isebenzisa ukunikezwa kwamandla okushintshayo, futhi ububanzi be-voltage yokufaka ngu-100 ~ 240V. Uma i-voltage ingaphezu kuka-240V, i-adaptha yamandla ingase ishiswe. Vula igobolondo lepulasitiki le-adaptha yamandla futhi ubone ukuthi i-fuse iqhume, i-varistor ishile, futhi enye yezikhonkwane ishisiwe. Sebenzisa i-multimeter ukukala ukuthi isekethe yamandla inomjikelezo omfushane osobala. Faka esikhundleni i-fuse kanye ne-varistor yokucaciswa okufanayo, bese uxhuma i-adaptha yamandla. I-adaptha yamandla isengasebenza ngokujwayelekile. Ngale ndlela, isekethe yokunikeza amandla okuvikela ku-adaptha yamandla iphelele.

Kusukela ekuhlaziyweni kwesekethe kwangempela, i-varistor ixhunywe ngokuhambisana nokokufaka kwe-diode yokulungisa ibhuloho. Umsebenzi wayo ukusebenzisa i-“Self Fusing” yayo uma kwenzeka kungena i-voltage ephezulu ngokushesha, ukuze kuvikelwe ezinye izingxenye zengxenye ye-adaptha yamandla ekulimaleni kwamandla kagesi aphezulu.

Ngaphansi kwesimo se-voltage evamile engu-220V, uma ingekho i-varistor yokucaciswa okufanayo esandleni, i-resistor ayikwazi ukufakwa ukuze isetshenziswe ezimweni eziphuthumayo.

Kodwa-ke, kufanele ifakwe ngokushesha ngemuva kokuthenga i-varistor. Uma kungenjalo, kuzoba nezinkinga ezingapheli, kusukela ekushiseni izingxenye eziningi ku-adaptha yamandla kuya ekushiseni ikhompyutha yamanothi.

Ukuze ulungise igobolondo lepulasitiki elihlakaziwe le-adaptha yamandla, ungasebenzisa i-polyurethane glue ukuyilungisa. Uma ingekho i-polyurethane glue, ungasebenzisa futhi itheyiphu kagesi emnyama ukugoqa imibuthano eminingana egobolondweni lepulasitiki le-adaptha yamandla.

2. Kuthiwani uma i-adaptha yamandla ikhala

I-adaptha yamandla yenza umsindo omkhulu kakhulu othi "squeak" ngesikhathi sokusebenza, okuphazamisa isimo sokugijima sabathengi.

Inqubo yesondlo: ngaphansi kwezimo ezijwayelekile, kuvamile ukuthi i-adaptha yamandla ibe nomsindo omncane wokusebenza, kodwa uma umsindo ucasula, leyo yinkinga. Ngoba ku-adaptha yamandla, kuphela uma kukhona igebe elikhulu elihambayo phakathi kwe-switching transformer noma indandatho yamagnetic ye-coil inductance kanye nekhoyili, "i-squeak" izobangelwa. Ngemva kokukhipha i-adaptha yamandla, hambisa ngobumnene ingxenye yamakhoyili kuma-inductors amabili ngesandla ngaphansi kwesimo sokungatholakali kwamandla. Uma ungekho umuzwa wokuxega, kuqinisekile ukuthi umthombo womsindo wokusebenza we-adaptha yamandla uvela ku-switching transformer.

Izindlela zokuqeda umsindo "we-squeak" wokushintsha i-transformer ngesikhathi sokusebenza zimi kanje:

(1) Sebenzisa i-soldering iron kagesi ukushisela kabusha amajoyinti e-solder axhuma phakathi kwezikhonkwane eziningana ze-switch transformer kanye nebhodi lesifunda eliphrintiwe. Ngesikhathi sokushisela, cindezela i-switch transformer uye ebhodini lesifunda ngesandla ukuze wenze iphansi le-switch transformer lixhumane eduze nebhodi lesifunda.

(2) Faka ipuleti lepulasitiki elifanele phakathi kwengqikithi kazibuthe nekhoyili yesiguquli esishintshayo noma ulivale ngeglue enziwe nge-polyurethane.

(3) Beka iphepha eliqinile noma amapuleti epulasitiki phakathi kwe-switch transformer kanye nebhodi lesifunda.

Kulesi sibonelo, indlela yokuqala ayinawo umphumela, ngakho-ke i-transformer yokushintsha ingasuswa kuphela ebhodini lesifunda, futhi umsindo "we-squeak" uqedwa ngenye indlela.

Ngakho-ke, lapho uthenga i-adaptha yamandla, kuyadingeka futhi ukulawula ikhwalithi ye-adaptha ye-adaptha yamandla ekhiqiziwe, okungase okungenani isindise ukuphazamiseka okuningi!
