Umgaqo osebenzayo wokuxhathisa ifeni ye-elektroniki, ukuxhathisa ifeni ye-elektroniki ziimpawu ezaphukileyo.
Guqula umbane ube bubushushu
Ukumelana kombane kwefeni ye-elektroniki kusebenza kakhulu ngokuguqula umbane ube ngamandla obushushu.
I-resistor kwi-electronic fan, eyaziwa ngokuba yi-thermistor, inendima ephambili ekujongeni ubushushu bee-motor windings. Xa ubushushu be-motor winding bunyuka, ixabiso le-resistance ye-thermistor liya kuncipha. Olu tshintsho lubangelwa kubudlelwane be-negative temperature coefficient phakathi kwexabiso le-resistance ye-thermistor kunye nobushushu, oko kukuthi, njengoko ubushushu busanda, ixabiso le-resistance liya kuncipha. Xa ixabiso le-resistance lifikelela kubushushu obuthile, liya kwehla liye kwixabiso elithile, nto leyo eya kubangela ukuba i-pre-value circuit icime ukusebenza, ukuze i-electrical fan iyeke ukusebenza. Le ndlela ngokwenene iyimpembelelo yokukhusela kwi-electrical fan, ithintela umonakalo ngenxa yokushisa kakhulu.
Ukongeza, umgaqo wokusebenza wokuxhathisa ukwabandakanya ukuguqulwa kombane. Xa umbane udlula kwi-resistor, ngenxa yempembelelo ye-thermoelectric ye-resistor, ubushushu bomphezulu we-resistor buya kunyuka, kwaye ixabiso langoku nalo liya kutshintsha. Ngokulungisa umbane, iiparameter zokumelana zinokulungiswa, njengexabiso lokuxhathisa kunye nexabiso langoku, ukuze kufezekiswe uzinzo lwesekethe kwaye kuthintelwe isiganeko sombane ogqithisileyo.
Ekusetyenzisweni kweefeni ze-elektroniki, ukumelana akupheleli nje ekudlaleni indima yokukhusela, kodwa kukwathatha inxaxheba kwinkqubo yokulawula isantya kunye nokulawula ubushushu befeni yombane. Umzekelo, kwifeni yokupholisa ye-elektroniki yeemoto, ukusebenza kwefeni kulawulwa ngeendlela ezahlukeneyo zokulawula (ezifana nemodi yokulawula "iswitshi ye-thermistor + relay"), kwaye isantya sefeni sihlengahlengiswa ngokuzenzekelayo ngokweqondo lobushushu bamanzi okanye isantya. Le ndlela yokulawula ayiphuculi kuphela ukusebenza kakuhle kwefeni yombane, kodwa ikwaqinisekisa ukusebenza kwayo ngokukhuselekileyo.
Iimpawu eziphambili zokungaphumeleli kokumelana nefeni yombane ziquka:
Umoya ophumayo awunakulungiswa, oko kukuthi, umoya ophumayo wefeni awunakulungiswa njengoko kufuneka.
Akukho giya ye-1234, kukho indawo yokuphuma enye kuphela, okanye ayisebenzi.
Ezi mpawu zibonisa ukuba i-resistor yefeni ye-elektroniki isenokuba yonakele, nto leyo ebangele ukuba ingasebenzi kakuhle. I-resistor isebenza njengokhuselo lokunciphisa umbane kunye nokukhusela i-overvoltage kwisekethe, kwaye xa yonakele, inokubangela ukuba ukuphuma komoya kwefeni kungakwazi ukulungiswa, okanye isenokungasebenzi konke konke. Ukongeza, xa i-resistor isebenza ngokuqhelekileyo, ukumelana kwayo akunasiphelo, xa i-voltage yokufaka idlula ixabiso elithile, ukumelana kwayo kuya kuba ncinci ngequbuliso, ukuze isekethe ibe yi-short circuit, inyanzelise i-fuse ukuba itshise imfutshane, idlale indima ekukhuseleni isixhobo.
Indlela yokulinganisa ngokuchanekileyo ukumelana nefeni yombane
Okokuqala, indima yokumelana nefeni yombane kunye neempazamo eziqhelekileyo
Ukumelana kwefeni yombane yenye yezona zinto zibalulekileyo ekulawuleni isantya sokusebenza kwemoto, esibonakala ngokutshintsha i-voltage yombane. Iimpazamo eziqhelekileyo ziquka umonakalo wokuxhathisa, unxibelelwano olubi okanye i-open circuit, njl.njl., nto leyo eya kubangela ukuba imoto ingasebenzi kakuhle.
Okwesibini, amanyathelo kunye neendlela zokulinganisa ukumelana
1. Nqamla umbane uze ususe isigqubuthelo sefeni ukuze ubonise ukuxhathisa.
2. Sebenzisa i-multimeter ukuchukumisa intonga yokulinganisa kuzo zombini iziphelo ze-resistance. I-multimeter kufuneka ibekwe kwi-resistance measure gear. Ukuba i-resistance iyalungiselelwa, beka i-multimeter kwi-rheostat gear ukuze i-resistance ifundwe ngokuchanekileyo.
3. Funda ixabiso lokumelana uze ulithelekise nexabiso lokulinganisa lemitha yokumelana. Ukuba ukufundwa kusondele kwixabiso lokulinganisa, ukumelana kuqhelekile; Ngaphandle koko ukumelana kuyonakala.
Okwesithathu, amanyathelo okhuseleko
1. Xa kulinganiswa ukumelana, umbane kufuneka ukhutshwe kuqala ukuze kuthintelwe iingozi.
2. Ukuba kusetyenziswa i-multimeter ukulinganisa ukumelana okuhlengahlengiswayo, jika i-resistor ibe yeyona xabiso liphezulu ngaphambi kokuvavanya ukuze ungonakalisi i-resistor.
3. Ukuba uqhagamshelo oluchaseneyo alulunganga, sebenzisa isepha ukucoca iindawo zoqhagamshelo kwaye ujonge ukuba izikrufu zibotshelelwe na.
Iv. Isiphelo
Ngokusebenzisa le ndlela ingentla yokulinganisa ukumelana, singakwazi ukufumanisa ngokukhawuleza nangokuchanekileyo ukuba ukumelana nefeni yombane kuyonakele na, ukuze sitshintshe ngexesha elifanelekileyo kwaye siqinisekise ukusebenza okuqhelekileyo kwefeni yombane. Kwangaxeshanye, kuyacetyiswa ukuba siqwalasele ukhuseleko xa sisebenzisa iifeni zombane kwaye singazisebenzisi kakhulu ixesha elide.
