1, Kugadzirisa muenzaniso welaptop simba adapta pasina voltage kubuda
Kana laptop iri kushandiswa, voltage inosimuka kamwe kamwe nekuda kwedambudziko remagetsi emagetsi, zvichikonzera kuti adapta yemagetsi kupisa uye pasina voltage inobuda.
Maitiro ekugadzirisa: iyo dhizaini yemagetsi inoshandisa switching magetsi, uye yekuisa voltage renji i100 ~ 240V. Kana iyo voltage ichipfuura 240V, iyo adapta yemagetsi inogona kupiswa. Vhura ganda repurasitiki readapta yemagetsi uye ona kuti fuse yakaputika, varistor yakatsva, uye imwe yepini yakatsva. Shandisa multimeter kuyera kana dunhu remagetsi rine pachena pfupi dunhu. Tsiva iyo fuse uye varistor yezvakatsanangurwa zvakafanana, uye batanidza iyo dhizaini yemagetsi. Iyo adapta yemagetsi ichiri kukwanisa kushanda zvakajairika. Nenzira iyi, iyo yekudzivirira simba rekupa dunhu mune yemagetsi adapta yakaringana.
Kubva pakuongorora chaiko kwedunhu, iyo varistor yakabatana mukuwirirana neinopinza yebhiriji rectifier diode. Basa rayo ndere kushandisa "Self Fusing" yayo kana ikaitika pakarepo yakakwira voltage intrusion, kuitira kuchengetedza zvimwe zvikamu zvechikamu chemagetsi adapta kubva mukukuvadzwa kukuru kwemagetsi.
Pasi pemamiriro eyakajairwa 220V magetsi emagetsi, kana pasina varistor yezvakafanana zvakatemwa paruoko, resistor haigone kuisirwa kushandiswa kwekukurumidzira.
Zvisinei, inofanira kuiswa pakarepo mushure mekutenga varistor. Zvikasadaro, pachave nedambudziko risingaperi, kubva pakupisa zvinhu zvakawanda muadapta yemagetsi kusvika pakupisa komputa yekunyorera.
Kuti ugadzirise iyo disassembled plastiki shell yemagetsi adapta, unogona kushandisa polyurethane glue kuigadzirisa. Kana pasina polyurethane glue, unogona zvakare kushandisa nhema tepi yemagetsi kuputira akati wandei kutenderedza goko repurasitiki readapta yemagetsi.
2, Ko kana iyo adapta yemagetsi ikarira
A adapta yemagetsi inoita ruzha rwakanyanya "squeak" panguva yekushanda, iyo inovhiringidza mhepo inomhanya yevatengi.
Maitiro ekugadzirisa: pasi pemamiriro akajairwa, zvakajairika kuti dhizaini yemagetsi ive neruzha rudiki rwekushandisa, asi kana ruzha ruchitsamwisa, ndiro dambudziko. Nokuti mumagetsi emagetsi, chete kana pane gomba guru rinofambisa pakati pekushandura transformer kana magnetic ring ye inductance coil uye coil, "squeak" ichakonzerwa. Mushure mekubvisa gadziriso yemagetsi, zvinyoronyoro fambisa chikamu chemakoiri pane maviri inductors neruoko pasi pemamiriro ekushaya simba. Kana pasina manzwiro ekusununguka, ichokwadi kuti iko kushanda kweruzha kweiyo adapta yemagetsi kunobva kune inoshandura shanduko.
Nzira dzekubvisa kurira kwe "squeak" yekushandura transformer panguva yekushanda ndeyotevera:
(1) Shandisa simbi yemagetsi solder weld yekubatanidza solder majoini pakati pemapini akati wandei eiyo switch transformer uye yakadhindwa redunhu bhodhi. Munguva yewelding, dzvanya switch transformer yakananga kudhiketi bhodhi neruoko kuti iite pasi peiyo switch transformer iri pedyo nepedyo nebhodhi redunhu.
(2) Isai ndiro yepurasitiki yakakodzera pakati pemagineti core uye coil ye switching transformer kana kuisimbisa nepolyurethane glue.
(3) Isa pepa rakaoma kana mahwendefa epurasitiki pakati pekuchinja kwekushandura uye bhodhi redunhu.
Mumuenzaniso uyu, nzira yekutanga haina simba, saka shanduko yekushandura inogona kubviswa chete kubva pabhodhi redunhu, uye "squeak" inzwi rinobviswa neimwe nzira.
Naizvozvo, kana uchitenga dhizaini yemagetsi, inofanirwawo kudzora kunaka kweiyo inogadzirwa magetsi adapta transformer, iyo inogona kunyanya kuchengetedza yakawanda kusagadzikana!
