Ungahlola kanjani i-fuse nge-multimeter
Okuqukethwe
Amasekhethi kagesi ahlukile ngomqondo wokuthi izingxenye ezincane zidlala indima ebaluleke kakhulu kuzo.
I-fuse ingenye yalezo zingxenye ezincane zokuzidela ezivimbela ukuphakama kwamandla okungalindelekile okungenza yonke isifunda sibe yize.
Ingabe idivayisi esekhaya lakho noma imoto ayiwatholi amandla? Ingabe usola ukuthi inkinga isebhokisini le-fuse? Wazi kanjani uma i-fuse ishaywa, okungase kubangele inkinga yakho?
Ngezinyathelo ezimbalwa nje ezilula, uzofunda ukuthi ungayihlola kanjani i-fuse nge-multimeter kusuka kulo mhlahlandlela.
Ake siqale.
Isebenza kanjani i-fuse?
Ama-Fuse ayizingxenye ezilula eziklanyelwe ukuvikela amasekhethi kagesi ekukhuphukeni kwamandla noma ekulayishweni ngokweqile.
Ikakhulukazi ihlanganisa intambo yensimbi encane noma intambo encibilikayo noma "eshayayo" lapho amandla amaningi edlula kuyo. Eyamanje ifuse engakwazi ukuyibamba yaziwa ngokuthi imanje yayo elinganiselwe, ehluka ukusuka ku-10A kuye ku-6000A.
Uhlobo oluvame kakhulu lwe-fuse olusetshenziswa ezinhlelweni ezihlukene zikagesi i-cartridge fuse, enomumo we-cylindrical, ngokuvamile ebonisa ngale, enezinsimbi ezimbili zensimbi nhlangothi zombili.
Ngaphakathi kunentambo yensimbi exhuma la matheminali amabili bese isha ngenxa yamandla amaningi ukuze ivimbele ukuhamba kwamandla kagesi phakathi kwazo.
Amathuluzi adingekayo ukuhlola i-fuse
Ukuze uhlole i-fuse udinga:
- i-multimeter
- I-Automotive Fuse Puller
Ungahlola kanjani i-fuse nge-multimeter
Setha i-multimeter yakho kububanzi obungu-200 ohm ukuze ulinganise ukumelana, beka ama-multimeter ama-negative and positive probe ekupheleni kwefuse ngayinye, bese ulinda kuze kube yilapho ukufundwa kunguziro (0) noma eduze noziro, okusho ukuthi i-fuse yinhle. Uma uthola ukufundwa kwe-"OL", khona-ke i-fuse yimbi futhi idinga ukushintshwa.
Sizobheka ngemininingwane ngayinye yalezi zinyathelo, kanye nazo zonke ezinye izinyathelo ezibalulekile.
- Khipha i-fuse
Isinyathelo sokuqala ukususa i-fuse kusekethe ekuyo. Yiqiniso, ukuthi i-fuse isuswa kanjani incike kumjikelezo, idivayisi, noma uhlobo lwe-fuse.
Kunoma yikuphi, ngaphambi kokwenza lokhu, nqamula umthombo wamandla ukuze ugweme ukushaqeka okubulalayo kagesi. Kufanele futhi uqaphele lapho ususa i-fuse ukuze ungalimazi.
- Setha i-multimeter ibe yi-ohms
Ukuhlola ama- fuse amaphutha kudinga ukuhlola ukumelana kwawo. Ukuze ulinganise ukumelana ne-multimeter, uvula ukudayela kwayo endaweni ye-Ohm.
Isethingi ye-ohm imelwe uphawu lwe-Omega (Ohm) ku-multimeter futhi njengoba uzobona nayo inobubanzi obuningi (2 MΩ, 200 kΩ, 20 kΩ, 2 kΩ kanye no-200 Ω).
Umkhawulo ongu-200 ohm ububanzi obufanele osethela i-multimeter yakho njengoba kuyibanga eliphakeme eliseduze elinikeza imiphumela enembe kakhulu.
Ngaphezu kwalokho, ungasetha futhi i-multimeter kumodi eqhubekayo, evame ukuboniswa uphawu lwegagasi lomsindo.
Manje, ngenkathi imodi yokuqhubeka nayo ilungele ukuhlola ukuthi intambo yensimbi iphukile noma cha, ayikuniki ukuxilongwa okuningiliziwe.
Isilungiselelo se-ohm yisona esihamba phambili, njengoba sikutshela ukuthi i-fuse yimbi, noma ngabe intambo yensimbi inganqamuki. Nika kuqala isilungiselelo se-ohm.
Ukuze uhlole ukuthi i-multimeter isethwe ngendlela efanele, beka imikhondo ephozithivu nenegethivu phezu komunye nomunye.
Ngesilungiselelo esifanele, uzothola uziro (0) noma usondele kuso ngokulungiselelwa kwe-ohm, noma uzozwa ibhiphu ye-multimeter kumodi eqhubekayo. Uma uwatholile, qhubekela esinyathelweni esilandelayo.
- Beka imikhondo ye-multimeter ekugcineni kwefuse
Lapha umane ubeke umkhondo we-multimeter ekugcineni kwephinikhodi ye-fuse, kungakhathaliseki ukuthi i-polarity.
Ukumelana nokulinganisa akudingi ukubekwa okuqinile kocingo oluphozithivu noma olunegethivu ekugcineni okuthile, ngakho-ke akumele ukhathazeke ngalokho. Ngemuva kokuthi izintambo zithintane kahle, hlola ukufundwa esikrinini semitha.
- Linganisa imiphumela
Imiphumela ilula kakhulu. Kumodi yokuqhubeka, uma i-multimeter ikhala, kusho ukuthi kukhona ukuqhubeka phakathi kwamatheminali amabili e-multimeter (i-metal filament Kulungile). Uma ungezwa ibhiphu, i-fuse iyashaywa futhi kufanele ishintshwe.
Kodwa-ke, ngisho nalapho i-multimeter ikhala, intambo yensimbi ingase ibe namaphutha athile, futhi kulapho ukuhlolwa kokumelana kusiza khona.
Uma i-multimeter isendaweni ye-ohm, amafuse amahle kulindeleke ukuthi akunikeze inani lokumelana likaziro (0) noma elisondele ku-zero.
Lokhu kusho ukuthi kukhona indlela eqhubekayo phakathi kwemikhondo emibili ye-multimeter (intambo yensimbi iseyinhle), futhi kusho nokuthi okwamanje kungageleza kalula kuyo uma kudingeka.
Inani elingaphezu kuka-1 lisho ukuthi kunokumelana okukhulu kakhulu ngaphakathi kwefuse, okungase kube isizathu sokuthi kungani kungagelezi okwamanje okwanele kuyo.
I-multimeter ingakubonisa futhi "OL", ebonisa ukuthi akukho ukuqhubeka nhlobo ku-fuse (intambo yensimbi ishaywa) futhi i-fuse idinga ukushintshwa.
Ukuhlola amafuse emoto nge-multimeter
Amafuse ezimoto anomumo ongavamile, njengoba anama-blades ezinhlangothini zombili, hhayi ama-protrusions. Zihlala isikhathi eside kunamafuse avamile futhi zitholakala ebhokisini le-fuse.
Ukuze uhlole i-fuse yemoto, qiniseka ukuthi imoto ivaliwe, hlola ishadi le-fuse lemoto yakho ukuze uthole i-fuse ethile yedivayisi enephutha, bese ususa i-fuse nge-fuse puller.
Manje usuyihlolela amachashaza amnyama abonisa i-fuse eshile noma eshaywayo, noma zama ukuhlola ukuthi intambo iphukile uma i-fuse isobala. Zibonisa i-fuse enephutha edinga ukushintshwa.
Uma ungatholi lutho olungalungile ngemva kokuhlola okubukwayo, landela inqubo evamile yokuhlola amafuse nge-multimeter. Setha imitha kububanzi obungu-200 ohm, beka ama-multimeter probe emaphethelweni amabili e-fuse, futhi uhlole inani esikrinini ngemva kokuxhumana okufanele.
Uma uthola uziro, inani eliseduze noziro, noma ibhiphu, i-fuse yinhle. Ukufunda "OL" nanoma yiliphi elinye inani kusho ukuthi i-fuse inesici futhi kufanele ishintshwe.
Okokugcina, lapho ushintsha ama-fuse, qiniseka ukuthi usebenzisa i-fuse entsha ene-amperage rating efana ne-fuse ehlulekile. Wenza lokhu ukuze ugweme ukufaka i-fuse edonsa amandla amanje kakhulu kunesidingo, engalimaza idivayisi noma isekethe eklanyelwe ukuyivikela.
Ividiyo yomhlahlandlela
Ungathola yonke inqubo kusiqondisi sethu sevidiyo:
Ngenkathi ungakwazi ukuhlola i-fuse ngaphandle kwe-multimeter, i-multimeter yedijithali iyindlela elula yokunquma ukuthi i-fuse yimbi. Kuwusizo futhi kwezinye izifo zokuxilonga zikagesi.
isiphetho
Ukuhlola amafuse nge-multimeter kungenye yezinqubo zokuxilonga zikagesi ezilula okufanele uzilandele uma ulandela amathiphu ethu. Umane ubeke ama-multimeter probe ekugcineni ngakunye bese ulinda ibhiphu noma inani elisondele ku-zero.
Qiniseka ukuthi uyayikhipha i-fuse kudivayisi kagesi ngaphambi kokuyibheka, futhi uphinde ufake i-fuse enesici esikhundleni se-fuse yesilinganiso esifanayo.
Imibuzo Evame Ukubuzwa
Wazi kanjani uma i-fuse ingalungile?
I-fuse ayisebenzi uma uthola ukuthi umucu wayo ugqashukile noma kunendawo emnyama kuyo, okukhombisa umlilo. Uphinde usebenzise i-multimeter ukukala ukuqhubeka noma ukumelana, okufanele kusondele ku-zero.
Iyiphi imbangela evame kakhulu ye-fuse yemitha ephephethiwe?
Isizathu esivame kakhulu samafuse aqhunyiswa ukugcwala kwesekethe. Ukulayishwa ngokweqile kwesiyingi kulapho izinto zikagesi eziningi kakhulu zidonsa amandla kusekethe ngokusebenzisa i-fuse, okubangela ukuvunguza kwesekhethi.
