Indlela ukulungisa okuphakela amandla?

Okuphakela amandla kuyingxenye ebaluleke kakhulu computer, ngaphandle ukuthi iyiphi idivayisi personalki ayikwazi ukuthola amandla. Le ngxenye ngokuvamile awahlelanga, kanye nokulungiswa okuphakela amandla kungaba kwenziwe ukuzama ekhaya. Kube ugaye nezinhlobo yomugqa, imodi wokusebenza futhi yiziphi kudivayisi ehlukile. block Linear siqukethe isimame kwaleli bhuloho diode futhi transformer. Esikhathini kudivayisi ishayela voltage ngoba powering generator is bulungiswe ibhuloho diode, bese asuswe transformer ephezulu imvamisa ze ukuhoxiswa olwengeziwe.

Balungise kwamandla kusetshenziswa amathuluzi anjenge-Phillips ukufakwa kokumqoka kuphela, yensimbi nokunamathisela ngomthofu, multimeter nge embili ukuhwebelana. Ngaphezu kwalokho, ikhithi edingekayo, drive kanzima noma umbadlana nakho kungase oscilloscope ewusizo futhi ezengeziwe (12) ugesi. Kumele kukhunjulwe ukuthi akuvunyelwe ukufaka kudivayisi ishayela ngaphandle umthwalo.

Ngo amadeskithophu ivame ATX amandla kagesi, indlela zokulungisa ehlukile ngempela.

Okokuqala, uma kwehluleka zedivayisi ukuhlola voltage eza ebhodini. Uma ayitholakali, kufanele ufune ukuba baphule ebhodini. Kungenzeka ukuthi isihlungi umsindo, ushintshe, izintambo, kungase kube izisekelo okuyiphutha. Uma konke kuhamba kahle, hlola voltage ukunikezela ngemva kwebhuloho diode. Khona-ke, enifeza ukulungiswa ATX ugesi, hlola fuse, ukumelana okufanele uhambe zero.

Okulandelayo ukubukeka varistor (kungakhathaliseki lwamanje kwalokho). Kulula ukwenza uma idivayisi. Uma izinga ugesi, imishini yayo ihlanganisa bushelelezi sokuqala esiminyanisa zamanje emazombezombe ukumelana okuyinto asondele zero.

Isinyathelo esilandelayo kuhlanganisa ekulungiseni isimo ugesi by kwebhuloho diode lapho ikhompyutha. It kumelwe lunikezwe kushintshana zamanje, uhambe - unomphela. diodes Kungenjalo okuyiphutha.

Umbhali wayevame ukunezela lokhu imbangela yokwehluleka zedivayisi itholakala ukwehluleka capacitor. Uma zehla noma avuvukele ukukhanda of amandla supply iwukuba esikhundleni izakhi idatha. Ukusebenza ephezulu voltage transistors kungaba ihlolwe nge multimeter.

Ngokuvamile uxazulula kukhompyutha yakho, kanye ukulungisa TV ugesi, kudinga ulwazi olukhethekile namakhono. Akukhona nje ube nomqondo othile ngokuthi umsebenzi lezi amadivaysi. Ngakho-ke kungcono ukuba baphendukele ochwepheshe nezikhungo zomsebenzi. Ngezinye izikhathi izindleko umsebenzi kungaba idlule intengo ugesi ezintsha. Ngakho, ke nanela ukuthi ushibhile: bayawukhanda noma bayawushintsha engeyokuqala kuhlulekile.

Ukuze sithole ukuthi iyunithi uphumile emgqeni, kungenzeka kuvalwe oxhumana omnyama oluhlaza (ukuxhumana Isixhumi kuya umbadlana). Uma izintambo uxhumano lwedatha, isibonelo, isiqeshana, iyunithi fan ayisebenzanga, ke idivayisi kungenzeka ukuba uphume oda. Ukujoyina Oxhumana nabo befoni bangaba kuphela ixhumeke kumsindo idivayisi inethiwekhi!
