Momwe mungayang'anire fuse ndi multimeter

Mabwalo amagetsi ndi apadera chifukwa chakuti zigawo zing'onozing'ono zimagwira ntchito yofunika kwambiri mwa iwo.

Fuseyi ndi imodzi mwazinthu zazing'ono zodzipereka zomwe zimalepheretsa kuwonjezereka kwamphamvu kosayembekezereka komwe kungapangitse dera lonse kukhala lopanda ntchito.

Kodi chipangizo chili mnyumba mwanu kapena mgalimoto yanu sichikupeza mphamvu? Mukuganiza kuti vuto lili m'bokosi la fuse? Kodi mungadziwe bwanji ngati fusesi ikuwombedwa, zomwe zingayambitse vuto lanu?

Munjira zingapo zosavuta, muphunzira momwe mungayesere fusesi ndi multimeter kuchokera mu bukhuli.

Tiyeni tiyambe.

Kodi fuse imagwira ntchito bwanji?

Ma fuse ndi zinthu zosavuta zomwe zimapangidwira kuti ziteteze mabwalo amagetsi ku mawotchi amagetsi kapena mochulukira.

Amakhala ndi kachingwe kakang'ono kachitsulo kapena waya kamene kamasungunuka kapena "kuwomba" pamene madzi ochulukirapo adutsa. Pakalipano yomwe fusesi imatha kugwira imadziwika kuti idavotera, yomwe imasiyana kuchokera ku 10A mpaka 6000A.

Mtundu wofala kwambiri wa fusewu womwe umagwiritsidwa ntchito pamagetsi osiyanasiyana ndi fusesi ya cartridge, yomwe imakhala yozungulira, nthawi zambiri imawonekera, yokhala ndi zitsulo ziwiri mbali zonse.

M'kati mwake muli chingwe chachitsulo chomwe chimagwirizanitsa ma terminals awiriwa ndikuwotcha kuchokera kumagetsi ochulukirapo kuti ateteze kutuluka kwa magetsi pakati pawo.

Zida zofunika kufufuza fuse

Kuti muwone fuse muyenera:

• multimeter
• Magalimoto a Fuse Puller

Momwe mungayang'anire fuse ndi multimeter

Khazikitsani ma multimeter anu pamlingo wa 200 ohm kuti muyeze kukana, ikani zoyeserera zoyipa komanso zabwino za multimeter kumapeto kulikonse kwa fuseyo, ndipo dikirani mpaka kuwerenga kukhale ziro (0) kapena kuyandikira ziro, kutanthauza kuti fuseyo ndiyabwino. Ngati mupeza kuwerenga kwa "OL", ndiye kuti fusesiyo ndi yoyipa ndipo iyenera kusinthidwa.  

Tiwona mwatsatanetsatane chilichonse mwamasitepewa, komanso gawo lina lililonse lofunikira.

1. Chotsani fusesi

Gawo loyamba ndikuchotsa fusesi kudera lomwe ilimo. Inde, momwe fusesi imachotsedwa zimatengera dera, chipangizo, kapena mtundu wa fusesi. 

Mulimonsemo, musanachite izi, chotsani gwero lamagetsi kuti mupewe kugunda kwamagetsi koopsa. Muyeneranso kusamala pochotsa fusesi kuti musawononge.

2.  Khazikitsani ma multimeter kukhala ohms

Kuyang'ana fuse ngati zolakwika kumafuna kuwunika kukana kwawo. Kuti muyese kukana ndi ma multimeter, mumatembenuza kuyimba kwake ku malo a Ohm.

Kuyika kwa ohm kumayimiridwa ndi chizindikiro cha Omega (Ohm) pa multimeter ndipo monga muwona kuti ilinso ndi magawo angapo (2 MΩ, 200 kΩ, 20 kΩ, 2 kΩ ndi 200 Ω). 

Malire a 200 ohm ndiye mulingo woyenera womwe mumayika ma multimeter anu popeza ndiwotalikirapo omwe amapereka zotsatira zolondola kwambiri. 

Kuphatikiza apo, mutha kuyikanso ma multimeter kukhala mosalekeza, omwe nthawi zambiri amawonetsedwa ndi chizindikiro cha phokoso.

Tsopano, ngakhale njira yopititsira patsogolo ndiyabwinonso kuyang'ana ngati chingwe chachitsulo chathyoka kapena ayi, sichikukupatsani chidziwitso chatsatanetsatane. 

Kuyika kwa ohm ndikwabwino kwambiri, monga kumakuwuzani ngati fusesi ili yoyipa, ngakhale chingwe chachitsulo sichinadulidwe. Ikani patsogolo makonzedwe a ohm.

Kuti muwone ngati multimeter yakhazikitsidwa molondola, ikani njira zabwino ndi zoipa pamwamba pa wina ndi mzake.

Ndi makonda olondola, mudzapeza ziro (0) kapena kuyandikira pafupi ndi ohm, kapena mudzamva beep ya multimeter mumayendedwe opitilira. Ngati munawalandira, pitani ku sitepe yotsatira.

3. Ikani ma multimeter kumapeto kwa fusesi

Apa mumangoyika zotsogola za multimeter kumapeto kulikonse kwa pini ya fuse, mosasamala kanthu za polarity.

Kuyeza kukana sikufuna kuyika mwamphamvu waya wabwino kapena woyipa kumapeto kwake, kotero simuyenera kuda nkhawa nazo. Pambuyo pa mawaya alumikizana bwino, yang'anani kuwerenga pazithunzi za mita.

4. Voterani zotsatira

Zotsatira zake ndizosavuta. Mumayendedwe opitilira, ngati ma multimeter akulira, zikutanthauza kuti pali kupitiliza pakati pa ma terminals awiri a multimeter (zitsulo zachitsulo zili bwino). Ngati simukumva beep, fusesiyo imawombedwa ndipo iyenera kusinthidwa.

Komabe, ngakhale multimeter ikulira, chingwe chachitsulo chikhoza kukhala ndi zolakwika zina, ndipo apa ndi pamene kuyesa kukana kumakhala kothandiza.

Ngati multimeter ili mu ohm setting, ma fuse abwino amayembekezeredwa kukupatsani mtengo wotsutsa wa ziro (0) kapena pafupi ndi ziro.

Izi zikutanthauza kuti pali njira yopitilira pakati pa mayendedwe awiri a multimeter (chingwe chachitsulo chikadali chabwino), komanso zikutanthauza kuti pakali pano imatha kuyenda mosavuta ngati pakufunika. 

Mtengo womwe uli pamwamba pa 1 umatanthawuza kuti pali kukana kwambiri mkati mwa fusesi, zomwe zingakhale chifukwa chomwe sichikuyenda bwino pakali pano.

Multimeter ikhoza kukuwonetsaninso "OL", kusonyeza kuti palibe kupitirizabe mu fuse (chingwe chachitsulo chikuwombedwa) ndipo fuseyi iyenera kusinthidwa.

Kuyang'ana ma fuse amagalimoto ndi multimeter

Ma fuse amagalimoto ali ndi mawonekedwe osazolowereka, popeza ali ndi "mabala" mbali zonse, osati zotuluka. Amakhalanso nthawi yayitali kuposa ma fuse okhazikika ndipo ali mu bokosi la fuse.

Kuti muyese fusesi yagalimoto, onetsetsani kuti galimotoyo yazimitsidwa, yang'anani tchati chagalimoto yanu kuti mupeze fuseyi ya chipangizo chomwe chili ndi vuto, kenako chotsani fuseyo ndi chokokera. 

Tsopano mumayang'anitsitsa mawanga akuda omwe amawonetsa fuse yowotchedwa kapena yowombedwa, kapena yesani kuwona ngati chingwe chathyoka ngati fuyusiyo ikuwonekera. Amawonetsa fusesi yolakwika yomwe ikufunika kusinthidwa.

Ngati simukupeza cholakwika mutayang'ana zowona, tsatirani njira yanthawi zonse yowonera ma fuse ndi multimeter. Khazikitsani mita ku 200 ohm range, ikani ma probes a multimeter kumapeto kwa tsamba la fuse, ndipo yang'anani mtengo pazenera mutatha kulumikizana koyenera. 

Ngati mupeza ziro, mtengo woyandikira zero, kapena beep, fusesiyo ndiyabwino. Kuwerenga "OL" kapena mtengo wina uliwonse kumatanthauza kuti fuseyo ndi yolakwika ndipo iyenera kusinthidwa.

Pomaliza, posintha ma fusesi, onetsetsani kuti mwagwiritsa ntchito fusesi yatsopano yokhala ndi ma amperage rating monga fuse yomwe yalephera. Mumachita izi kuti mupewe kuyika fusesi yomwe imakoka kwambiri kuposa momwe imafunikira, yomwe ingawononge chipangizocho kapena dera lomwe lapangidwa kuti liziteteza.

Kanema Wotsogolera

Mutha kupeza njira yonse mu kalozera wathu wamavidiyo:

Momwe Mungayesere Fuse Ndi Multimeter

Ngakhale mutha kuyesa fuse popanda multimeter, multimeter ya digito ndiyo njira yosavuta yodziwira ngati fusesi ndi yoyipa. Ndiwothandiza kwa zina zamagetsi diagnostics.

Pomaliza

Kuyang'ana ma fuse okhala ndi ma multimeter ndi imodzi mwa njira zosavuta zowunikira zamagetsi zomwe mungatsatire ngati mutsatira malangizo athu. Mumangoyika ma probe a multimeter kumapeto kulikonse ndikudikirira beep kapena mtengo womwe uli pafupi ndi ziro.

Onetsetsani kuti mwachotsa fuyusi ku chipangizo chamagetsi musanayang'ane, komanso m'malo mwa fuseyi yolakwika ndi fusesi ya mlingo womwewo.

FAQ

Kodi mungadziwe bwanji ngati fusesi ndi yoyipa?

Fuseyo imakhala yolakwika ngati mupeza kuti ulusi wake wathyoka kapena pali malo amdima, kusonyeza moto. Mumagwiritsanso ntchito ma multimeter kuti muyese kupitiliza kapena kukana, komwe kuyenera kukhala pafupi ndi ziro.

Kodi choyambitsa kwambiri cha fuse ya mita yowomberedwa ndi chiyani?

Chomwe chimayambitsa ma fuse omwe amawomberedwa ndi kuchuluka kwa ma circuit. Kudzaza mozungulira ndi pamene zida zambiri zimakoka magetsi mozungulira kudzera mu fusesi, zomwe zimapangitsa kuti dera liwombe.
