Kwenziwa kanjanivimbela izintambo nezintamboekubambeni umlilo ngenxa yezintambo ezigcwele kakhulu!
Ngesikhathi sokusebenza kocingo nekhebula, ukushisa kuzokwenziwa ngenxa yokuba khona kokumelana.Ukumelana nocingo ngokuvamile kuncane kakhulu, futhi amandla ayo okushisa angavezwa ngefomula q=I^2R.q=I^2R ikhombisa ukuthi: ocezwini locingo ekusetshenzisweni kwangempela (R ngokuyisisekelo ayiguquguquki), uma amandla amanje adlula ocingweni abe mkhulu, amandla okushisa aba makhulu;uma i-current ihlezi, amandla okushisa ocingo nawo ahlala njalo..Ukushisa okukhishwe ngesikhathi sokusebenza kuzomuncwa intambo ngokwayo, kubangele ukuthi izinga lokushisa lentambo likhuphuke.Nakuba ucingo luhlala lumunca ukushisa okukhishwe okwamanje futhi lwenza umsebenzi ngesikhathi sokusebenza, izinga lokushisa layo ngeke likhuphuke ngokungenamkhawulo.Ngenxa yokuthi intambo idonsa ukushisa, iphinde ikhiphele ukushisa emhlabeni wangaphandle.Iqiniso libonisa ukuthi izinga lokushisa locingo likhuphuka kancane kancane ngemva kokuba ucingo lunikezwe amandla, futhi ekugcineni izinga lokushisa lihlala njalo endaweni ethile.Kuleli qophelo elingaguquki, ukumunca ukushisa namandla okukhipha ukushisa kwentambo kuyafana, futhi intambo isesimweni sokulingana okushisayo.Kukhona umkhawulo emandleni ama-conductor ukumelana nokusebenza okuphezulu kwezinga lokushisa, futhi ukusebenza okungaphezu kwezinga elithile lokushisa eliphezulu kungaba yingozi.Lokhu kushisa okuphezulu ngokwemvelo kuhambisana nesilinganiso esiphezulu samanje, futhi intambo egijima ngale kwalesi silinganiso esiphezulu samanje igcwele ngokweqile.Ukulayisha ngokweqile ucingo kwandisa izinga lokushisa locingo ngokwalo kanye nezinto ezizungezile.Ukwenyuka kwezinga lokushisa kuyimbangela eqondile yomlilo onjalo.
Ukulayisha ngokweqile kulimaza isendlalelo sokuhlukanisa phakathi kwezintambo ezinemicu emibili, kubangele ukujikeleza okufushane, ukushisa okokusebenza, futhi kubangele umlilo.Izintambo ezinama-double-strand zihlukaniswa yi-insulating layer phakathi kwazo, futhi ukulayishwa ngokweqile kuzothambisa futhi kubhubhise isendlalelo se-insulating, okuzokwenza ukuthi ukuxhumana okuqondile kwezintambo ezimbili kubangele isifunda esifushane futhi kushise imishini.Ngesikhathi esifanayo, izinga lokushisa eliphezulu elikhiqizwa amandla amanje aphezulu ngesikhathi sesifunda esifushane kubangela ukuthi umugqa ubambe umlilo kanye ne-fuse, futhi ubuhlalu obuncibilikisiwe obukhiqiziwe buwela ezintweni ezivuthayo futhi bubangele umlilo.Ukwenyuka kwezinga lokushisa okugcwele ngokweqile kungathungela ngokuqondile izinto ezivuthayo eziseduze.Ukudluliswa kokushisa kwentambo egcwele kakhulu kwandisa izinga lokushisa lezinto ezivuthayo eziseduze.Ezintweni ezivuthayo eziseduze ezinamaphoyinti aphansi okushisa, kungenzeka ukuvutha futhi kubangele umlilo.Le ngozi igqame ikakhulukazi ezindlini zokugcina izimpahla lapho kugcinwa khona izinto ezivuthayo kanye nezakhiwo ezinemihlobiso esebenziseka kalula futhi evuthayo.
Ukulayishwa ngokweqile kuphinde kudalule ukuxhumana kulayini ezimweni ezishisa ngokweqile, okusheshisa inqubo ye-oxidation.I-oxidation ikhiqiza ifilimu encane ye-oxide engaqhubeki kalula ezindaweni zokuxhuma, futhi ifilimu ye-oxide ikhulisa ukumelana phakathi kwamaphoyinti okuxhumana, okuholela ezinhlansini nezinye izenzakalo, ezibangela umlilo.
Ngakho-ke, kanjani ukuvimbela umlilo obangelwa ukugcwala kwezintambo nezintambo?
1. Enkambweni yokuklama umugqa, umthamo wesayithi kufanele uhlolwe ngokunembile, futhi kungenzeka ukuthi ungeze umthamo omusha esikhathini esizayo kufanele kucatshangelwe ngokugcwele, futhi kufanele kukhethwe uhlobo olufanele locingo.Uma umthamo mkhulu, izintambo ezinkulu kufanele zikhethwe.Idizayini yesiyingi nokukhetha okunengqondo yizinyathelo ezibalulekile zokuvimbela ukugcwala.Uma umklamo ukhethiwe ngendlela engafanele, kuyoba nezingozi ezifihliwe zokuzalwa okunzima ukuzilungisa.Amanye amaphrojekthi amancane nezindawo akuklanyelwe futhi kukhethwe ngokucophelela.Kuyingozi kakhulu ukukhetha nokubeka imigqa ngokuthanda kwakho.Izinto zikagesi ezintsha kanye nezinto zikagesi kufanele zicabangele ngokugcwele umthamo wokuthwala wezintambo zokuqala.Uma umugqa wangempela ungahlangabezani nezidingo, kufanele uklanywe kabusha futhi wakhiwe kabusha.
2. Imigqa kufanele yakhiwe futhi ibekwe ngabasebenza ngogesi abaqeqeshiwe ngokuhambisana nemininingwane efanele.Izimo zokubeka imigqa zithinta ngokuqondile ukuchithwa kokushisa kwezintambo.Ngokuvamile, ukubeka umugqa akufanele kudlule ezintweni ezilula, ezivuthayo kanye nokupakishwa, okuzoholela ekulahlekeni kokushisa okungalungile kwezintambo, ukuqoqwa kokushisa, ithuba lokuthungela izinto ezivuthayo ezizungezile, nokwandisa ingozi yomlilo obangelwa ukugcwala ngokweqile;Imigqa ebekwe ophahleni lomhlobiso wezindawo zokuzijabulisa zomphakathi kufanele ivikelwe ngamapayipi ensimbi, ukuze uphahla luhlukaniswe nemigqa, futhi noma ngabe kukhona ubuhlalu obuncibilikisiwe obungaphansi kokulayishwa ngokweqile, isifunda esifushane, njll., ngeke siwe. vala, ukuze ugweme umlilo.
3. Qinisa ukuphathwa kwamandla, gwema izintambo ezingahleliwe kanye nezintambo, futhi usebenzise amasokhethi eselula ngokuqapha.Izintambo ezingahleliwe, izintambo ezingahleliwe, kanye nokusetshenziswa kwamasokhethi eselula empeleni kwengeza okokusebenza kagesi engxenyeni ethile yolayini, okwandisa inani lamanje futhi okungenzeka kubangele ukugcwala ngokweqile.Ama-jack socket jacks ngokusobala angaphezulu kwamasokhethi angaguquki odongeni.Uma kusetshenziswa izinto zikagesi eziningi kakhulu kumasokhethi eselula, isekethe yokuqala ngeke ibekezeleleke.Okokusebenza okunamandla amakhulu nezinto zikagesi, kufanele kumiswe izintambo ezihlukene, futhi amasokhethi eselula akufanele asetshenziswe njengemithombo yezintambo.
