I fusethi yintoni? Umgaqo wokusebenza kwamafomu

I-elektroniki kwimoto ixanduva lweenkqubo ezininzi kunye nessystems. Ukukhanyisa, ukulalelwa, ukupholisa, ewe apho, awuyi kuqhuba iinjinjini ukuba umbane uphuma. Ngelishwa, abaninzi abaqhubi "bahambi" kulo mmandla kwaye abahlala bekwazi ukuhlangabezana nokusilela kwesekethe zombane, nangona iimeko ezinzima zidibaniswa kuphela nefusethi yokutshiswa. Le yindlela yokukhusela, edla ngokuphazamiseka kwaye iphazamise abaqhubi. Kule nkcazelo elandelayo, siza kuxubusha ngokubanzi malunga nento eyona fusethi, indlela esebenza ngayo nendlela yokwenza indawo xa kwenzeka ukungaphumeleli komnye wabo.

Yintoni i fuse?

Ifestile iyisistim ekhethekileyo sokutshintsha kombane onomsebenzi wokunqanyula isiphaluka esikhuselekile ngokuyivula okanye ukutshabalalisa (ukutshisa) iindawo ezihamba phambili eziqhubekileyo xa ezikhoyo zikhoyo ziphezulu. Ngokuthethileyo, i-fuse yindlela yokukhusela eyonakalisa ukutshatyalaliswa kwimeko yesongelo kuyo yonke i-electronics (kwimoto okanye kwizixhobo zombane). Uhlobo lokuzibingelela, ukuba ucinga ngemifanekiso.

I fuse isebenza njani?

Kwiimoto zefestile zisetyenzisiweyo kwaye zikhethwe ngokuhambelana nomthwalo ogunyazisiweyo. Xa kwenzeka imeko yongxamiseko, xa i-voltage iphakama, isiqhagamshelo sefesti yomfesane siphula phantsi kwaye sivula isiphaluka kagesi.

Inkqubo yokutshatyalaliswa iqala ukuba:

• Isigqeba esifutshane - senzeke ukuba ukuxutywa kwamalungu athileyo okanye ukuxhomekeka okungalunganga kwezixhobo kuphuliwe. Ingxaki yezicatshulwa ezicatshulwayo emotweni ngokuqhelekileyo yimbangela yezihlandlo ezifayo.
• Ukungahambelani kwamandla kwesoxhobo somthengi kunye nomyinge ochongiweyo ovunyelwe kwisiphaluli esithile. Le ngxaki ijongene nalabo bathetha ukufaka kwiimoto zabo ezongezelelweyo izixhobo zombane (ukukhanyisa, i-redio kunye nabanye abafana nabo). Amandla anamandla anjalo anikezelwa ngumbambo wesiseko ongeyilungiselelwe ukuxabisa okwangoku. Ngenxa yobukhulu bamandla okwangoku, iifowuni ziyahlanjululwa kwaye zikhokele kwisiphaluka esifutshane, esikhokelela ekufakeni i-fuses ngaphandle komyalelo.

Ukukhusela iifsi

Ukusuka ngasentla, kuyacaca ukuba i-fuse emotweni iyachithwa xa kunqunyanyiswa ixabiso lomlinganiselo lombane. I fuse inxalenye yefusethi ishushu kwaye iyatshisa.

I-current rate of fuse ibalwa ngolu hlobo: Inom = Pmax / U.

• I-inom yinto ekhethiweyo yangoku elandelwa kwii-Amps;
• I-Pmax iyona mthwalo ophezulu umthwalo onikezelweyo. Amandla aboniswa kwiixhobo kwaye lilinganiswa kumatshini;
• U yinqanaba lombane lomnatha. Esi sibonakaliso silinganiswa kwiiVolts. Izinga lamandla emnatha wezithuthi li-12 Volts.

Iifom zefayile

Amafaysi ahlelwe ngokwemandla elinganisiweyo, kunye nobukhulu befayili.

Ngokwesayizi, iifomu ziyahlula zibe:

• I-Micro - eyona nto ifakile.
• I-Mini - encinci (iimitha eziyi-16).
• Isiqhelo sisayizi obuqhelekileyo (i-19 millimeters).
• I-Maxi yona mkhulu kunabo (ama-millimitha angama-34).

Yintoni ebaluleke ngakumbi ukuhlukana ngokwemandla yangoku. Ukuze kube lula, bonke baphawulwe ngemibala ethile, kodwa akufanelekanga kugxininise kumbala, kuba kwiimoto zeVAZ zifakwe imbala eyahlukileyo nakwezinye iimoto zangaphandle, kuba akukho migaqo kule ndawo.

Fuse Indawo

Into yokuqala umqhubi wemoto uza kufuneka abhekane nayo xa ezama ukujonga imeko yefestile okanye ukuyibuyisela kuyo ukukhangela ibhokisi lokukhusela. Into eyiyo, ukufumanisa apho i-fuse ikhona khona, umsebenzi awuyinto encinane. Kwiimodeli ezahlukeneyo zeemoto, ibhokisi lefestile lifumaneka kwiindawo ezahlukeneyo zekhabini okanye nangaphantsi kwebhodi. Ngamanye amaxesha inani lamafestile landa kakhulu, kwaye umenzi wemoto ubeka iibhloko ezininzi kwiindawo ezahlukeneyo zomatshini. Ngenxa yolu bungozi, akunakwenzeka ukuba ucebise icebo okanye umyalelo wokufumana indawo yokukhusela. Ngokomzekelo, kwimveliso yasekhaya yeefusi ziphantsi kwekhowudi (inguqulo yeklasi yeendawo "iLada"). Kwiimoto zangaphandle le meko iyinkimbinkimbi. Iifom kwi-Toyota Corolla zisekunene kwevili lokuqhuba kwideshibhodi. Kubonakala ngathi abavelisi belizwe elinye bafanele bafanane nokukhetha indawo yezinto, kodwa ngokwenene yonke into iyahluke. Iifomu kwi-Almera yeNissan zifumaneka ngakwesobunxele besondo lokuqhuba, kwi-pocket encinane.

Uvavanyo lweFuse

I-fuse yokusebenza iyona nto yokuqala kunye nokhuseleko. Ngoko ke, kuyimfuneko ukuyigcina ngokusebenza. Ukuba kukho nayiphi na into ekhompyutheni emotweni ayiphumelelanga, kuyimfuneko ukuhlolisisa amandla okusebenza kwengcaciso. Oku kwenziwa njani? Abaqhubi abaninzi bafumana ukufikelela kwinqanaba lokukhusela kwaye bathathe amafomu ukuze bahlole imeko yabo. Abanikazi beemoto bajonge nje, ingaba i-jumper kwi fuse ibonakaliswe. Kakade, le ndlela isebenza, kodwa iyafana ne-dilettantes, kwaye ngaphandle koko, ayisoloko ithembekile, kuba i-jumper inokuhlala iphelele nangona i-fuse iyashiswa. Ukuqwalasela imeko yeengxenye, kungcono ukuquka isiphaluka eyeke ukusebenza (le nto ingaba yiphina i-electronics, ingaba izibane, isitofu okanye isimiso se stereo), kwaye sebenzisa i-multimeter ukujonga izinga le-voltage kwi-fuse elijongene nale circuit. Uvavanyo olunjalo luza kuthatha ixesha elincinci kwaye linike umphumo ochanekileyo.

Ukutshintsha iifom

Ukuba i-fuse iyaphela, kufuneka ithathe indawo ngokukhawuleza. Okokuqala siyifumana ibhokisi lefestile (ukuba inyunithi ikhona phantsi kwebhodi, ibhetri kufuneka ikhutshwe kwangaphambili). Susa iibhotshi ezivela kwiphepha lekhuseleko. Sebenzisa isikhonkco se-10 ukuze unqamle umnqweno, obambe iqhosha ngemicingo. Oku kwenziwa ukwenzela ukuba bahambise (bavala ukufikelela kwiifom). Kwakhona, ukuze uthuthuzele kakhulu, unokuqhawula iphaneli ngefestile, kodwa oku akuyimfuneko. Emva koko sitshintshisa i-fuse engasebenziyo kwaye sibeke kwindawo yayo entsha (eqinisweni, ifanelekileyo ngobukhulu kunye nexabiso lobuso).

Ukukhetha nokuvavanya i fuse

Ukukhetha ukuba yiyiphi i fuse oyifunayo, kufuneka ugcine engqondweni ethile imiqathango. Xa ukhetha inxalenye entsha, kuyimfuneko ukufaka izicelo kuphela kubakhiqizi abaqinisekisiweyo, abajongene nomgangatho weemveliso zabo. Kucebise ukubonisana nabanye abaqhubi abaneemoto ezifanayo kunye nomthwalo kwisiphaluka zombane. Oku kubaluleke kakhulu, njengoko amaninzi amafomu akwenziwa eChina, apho kungekho mntu olawula le nkqubo. Ngenxa yeemveliso ezinobulunga, awukwazi nje ukutshabalalisa i-electronics, kodwa yonke imoto. Kuye kubekho iimeko xa ibhokisi enefesti yatshisa, kodwa iifom zihlala zizinzile.

Ukujonga ubungakanani bendawo, kuyimfuneko ukukhupha isiphaluka esifutshane ngaphandle kwemoto, kwaye ukuba i-fuse iyashisa, ithetha ukuba imgangatho kwaye ungathabatha lonke iqashiso ukuze ubeke endaweni eyonakalisiweyo kwimoto yakho.

Ukwenza isiphaluka esifutshane esifanelekileyo, kuyimfuneko ukukhawuleza ekupheleni kwefayile kwifowuni, kwaye ke omnye wabo kufuneka axhumeke kwi-plus, kunye neyesibini ekugqibeleni aze abeke umbane wamandla kunye nombane ophezulu ngaphezu kwegama.

Ukufakwa kwezixhobo ezongezelelweyo

Ukuba uceba ukufaka izixhobo ezongezelelweyo kwimoto, kuyimfuneko ukufumana ukuba i-wiring evamile yemoto yakho iya kumelana nomthwalo onjalo. Ukuba akunjalo, kuba izixhobo ezintsha ziya kubakho ukuqhuba i-wiring ehlukeneyo, kwaye i-current rate of fuse kuyo kufuneka ibe sisihlandlo esinye nesigxina esiphezulu kunomlinganiselo okhoyo kwisiphaluka. Ukubala umthwalo, ungasebenzisa umthetho ka-Ohm kunye neetafile ezikhethekileyo.
