Fuse - Iyini? Umgomo we operation ye fuses

Electronics kule moto unesibopho ezihlukahlukene izinhlelo kanye subsystems. Ukukhanyisa, umshini wokukhulisa Ukupholisa ngomoya, kodwa yini lapho, ungenawo ngisho ukuqala injini uma ukwehluleka amandla. Ngeshwa, kule ndawo "iflothi" kanye nabashayeli abaningi akuzona njalo bakwazi ukubhekana nezinkinga circuit kagesi, naphezu kweqiniso lokuthi ngokuvamile lapho umuntu enezinkinga ezihambisana kuphela fuse kushaywa. Kuyinto indlela ukuvikela ukuthi liza laphinde labhidlika futhi kuphazamisa abashayeli. Esikhathini follwing material ngaphezulu nixoxe ngalokho-fuse, njengoba usebenza njengoba esikhundleni uma kwenzeka ukwehluleka Kolunye lwazo.

Uyini fuse?

Fuse - a kagesi idivayisi ekhethekile usuke, ogama msebenzi unqamule wesifunda ivikelwe ukuvulwa noma ukuwohloka yayo (esivuthayo) izingxenye conductive enikeziwe kusengaphambili ezidlulayo i zamanje eziphakeme ngokwedlulele kuye kagesi ngokusebenzisa kwabo. ukukhuluma Cishe, fuse - livikela mshini zokuzilimaza endabeni usongo lonke electronics (imoto noma izinto zikagesi). A uhlobo wokuzidela, uma ukhuluma njengesifenqo.

Isimiso ezisebenza we-fuse

Izimoto ezisetshenziswa kanye fuses akhethiwe ngokuhambisana ukalwe umthwalo umthamo. Esimweni esiphuthumayo lapho voltage liphume, fuse fuse kuvula bese ephula i wesifunda kagesi.

inqubo Self-ukubhujiswa ithoma endabeni:

• short circuit - kwenzeka lapho uphule ukwahlukanisa izingxenye conductive noma uxhumano okungafanele amadivayisi. Inkinga Uqothukile ikhebula ukwahlukanisa emotweni nhlobo, yezimbangela njalo iningi ukwehluleka fuse.
• Incompatibilities amandla oqothulayo amadivayisi futhi amandla okuzisholo wamanje, esivunyelwe wesifunda ethile kagesi. Lena inkinga ezibhekene labo abanquma ukufaka emotweni yakho extra imishini kagesi (ukukhanyisa, umsakazo nokunye okufana nabo). Enjalo enamandla amandla abathengi ezidla kusukela base bakha imizila edingekayo yokwenza, okungasekelwe eyenzelwe imali enjalo ephakeme zamanje. Ngenxa amandla izintambo phezu-kwamanje elicibilikile kuholele short circuit, ukuthi okukhiphayo ukuhluleka fuse.

Fuse ezithothene embundwini

Kulokhu okungenhla kuyacaca ukuthi fuse imoto iphuka uma okweqa ukalwe amandla value. A fusible fuse ingxenye overheats futhi liphele.

Fuse ukalwe zamanje ibalwa ifomula: Inom = Pmax / U.

• Inom - the okuzisholo Inani lamanje, okuyinto ulinganiswa amperes;
• Pmax - esiphezulu umthwalo kungenzeka, okuyinto angakwazi ukusingatha umshini othile. Amandla kuboniswa kwidivaysi bese ulinganiswa Watts;
• U - yizinga we amapayipi voltage. It is kulinganiswa ngo volts. Izinga voltage kunethiwekhi imoto 12 volts.

izinhlobo fuses

Fuses zehlukaniswe ngokwamandla ukalwe, kanye ubukhulu fuses ngokwabo.

On ubukhulu fuses zihlukaniswe zibe:

• Micro - icwecwe kakhulu.
• Mini - kancane ngaphezulu (16 kwangu).
• Okuvamile - olingene (19 mm).
• Maxi - ngobukhulu (34 mm).

Okuningi ezibalulekile division of amandla zamanje. Ukuze kube lula, konke ziphawulwe umbala ethile, kodwa ngokuyinhloko uncika umbala akudingekile, njengoba e Vaz fuses ziphawulwe umbala azisafani izimoto angaphandle, ngoba akukho amazinga kulo mkhakha alikho.

fuse

Into yokuqala nobuso umshayeli ngenkathi kuzanywa hlola fuses noma esikhundleni sawo - thola ibhokisi ukuphepha. Into wukuthi ukuthola lapho fuse itholakala, hhayi umsebenzi eziwubala. Ngo onobuhle ezahlukene imishini fuses block elise ezingxenyeni ezahlukene kuleli gumbi engangikulo umgibeli noma ngaphansi hood. Ngezinye izikhathi inani fuses luyanda kakhulu, futhi umakhi auto esegqoka amabhlogo amaningana ezindaweni ezihlukahlukene umshini. Ngenxa kunokudideka okungaka ukunikela isikimu jikelele noma search ibhukwana iyunithi ukuphepha akunakwenzeka. Ngokwesibonelo, e imishini ye fuses yasekhaya ukukhiqizwa zitholakala ngaphansi bonnet (zakudala isakhiwo inketho "Zhiguley"). Ngo izimoto angaphandle iyinkimbinkimbi kakhulu kunalokho. Fuses ku "yohlobo lweToyota Corolla" elise kuya kwesokudla amasondo ayo kuyi-dashboard. Kunengqondo ukuphetha ngokuthi abakhiqizi ezweni elilodwa Kufanele kube okufanayo kukhethwa indawo izinto, kodwa empeleni ngenye indlela. Fuses ku "Nissan Almera" elise kwesokunxele amasondo ayo, ephaketheni elincane.

Hlola fuses

Ukusebenza fuse - ke ngokuyinhloko ukuphepha. Ngakho-ke kubalulekile ukuba uwagcine isimo ukusebenza. Uma kuphunyuka umuntu walaba elementi e-elekthronikhi emotweni uphumile emgqeni, kufanele uhlole imininingwane ukusebenza. Indlela ukukwenza? Abashayeli abaningi bamane ukufinyelela iyunithi ukuphepha vula fuses ikhishiwe ngenxa kokuhlaziywa ezibukwayo yesimo sabo. abanikazi Car umane bheka ukuze ubone uma fuse jumper lilimele. Yiqiniso, le ndlela isebenza, kodwa ejwayelekile nayizimfundamakhwela, futhi ngaphandle kwalokho, asinakuyethemba njalo, ngoba ibha obungahlala bunjalo ngisho noma fuse kushaywa. Ukuze uhlole isimo izingxenye kungcono ukufaka iketango ukuthi wayeka isebenze (kungaba iyiphi electronics, ngabe kungcono izibani, isitofu noma uhlelo stereo), bese usebenzisa i-multimeter ukuhlola ezingeni voltage ku-fuse, unesibopho lesi sifunda. Lokhu kuqinisekisa kuthatha isikhathi esincane futhi bayokwenza umphumela olunembile.

Njengoba ezothatha isikhundla fuses

Uma fuse kuhlulekile, kumele kube indawo ngokushesha. Ukuze uqale, thola ibhokisi fuse (uma iyunithi itholakala ngaphansi hood, ibhethri kufanele inqanyuliwe kusengaphambili). Susa ngezikulufo kusukela isembozo fuse ibhokisi. Ukudonsa 10 uyasikrufulula nut ebamba ngocingo kuya izintambo. Lokhu kwenziwa ukuze uzihambise (bona ukuvala ukufinyelela fuses). Futhi iphaneli nge fuses angasuswa ukuze athole induduzo ngaphezulu, kodwa lokhu into ozikhethela wena. Khona-ke mane ususe okungenamsoco fuse bese efakwa endaweni yayo entsha (Yiqiniso, ubukhulu sokunene par).

Khetha bese uhlole fuse

Ukukhetha fuse kuyadingeka ukuze sikusize, kumelwe uyikhumbule lezimo eziningana. Ukukhetha into entsha, kumelwe ukuba ufinyelele kuphela abakhiqizi othembekile obhekene izinga imikhiqizo yayo. Kuyinto efiselekayo uthintane izimoto abanye abashayeli Kutholwe ezifanayo nomthwalo wesifunda. Lokhu kubaluleke kakhulu njengoba iningi fuses ekhiqizwa in China, lapho le nqubo kungalawulwa yinoma ubani. Ngenxa imikhiqizo onesici abakwazi kuphela ukubhubhisa electronics, kodwa futhi wonke imoto. Kwakuba nezikhathi lapho kushiswe fuse isivimbo fuses ngokwabo bunjalo.

Ukuhlola izinga imininingwane, kubalulekile ukuba avuse short circuit ngaphandle imoto, futhi uma ushaywa fuse, khona-ke ungakwazi ukuthatha ikhwalithi wonke party, ukuze kungene esikhundleni ezilimele imoto yakho.

Ukwakha i-yokufakelwa isekhethi isidingo primotat ukuxuba emikhawulweni wire, bese omunye wabo ixhunywe omuhle, futhi yesibili engemihle futhi siyinqobe kubo i kagesi nge voltage ephakeme ukwedlula bokuzisholo.

Ukufakwa imishini ezengeziwe

Uma uhlela ukufaka izesekeli imoto, kubalulekile ukunquma ukuthi wiring esezingeni imoto yakho ume umthwalo ongako. Uma kungenjalo, khona-ke imishini emisha uzodinga ubambe wiring ehlukile futhi ubukhulu fuse kuye ukuba nohafu ephakeme kunaleyo wamanje ezingu-circuit. Ukuze abale umthwalo ungasebenzisa umthetho Ohm sika namathebula ekhethekile.
