Momwe mungayang'anire fuse yotentha ndi multimeter

Ma fuse amawotcha nthawi zambiri amawomba chifukwa cha kuchuluka kwa mphamvu komanso nthawi zina chifukwa cha kutsekeka. Simungangoyang'ana fusesi ndikuwona ngati ikuwombedwa, muyenera kuyesa kuyesa kopitilira.

Kufufuza kosalekeza kumatsimikizira kukhalapo kwa njira yamagetsi yosalekeza. Ngati fuseji yotentha imakhala ndi umphumphu, ndiye kuti ikugwira ntchito, ndipo ngati sichoncho, ndiye kuti ndi yolakwika ndipo iyenera kusinthidwa.

Nkhaniyi ifotokoza njira zingapo zosavuta kuti muwone ngati fusesi ili ndi dera lopitilira kapena ayi. Kuti muchite izi, mufunika multimeter, makamaka multimeter ya digito.

Kuti muyesedwe, muyenera kutsatira izi:

1. Pezani ndi kuchotsa fuse mu chipangizo chanu,

2. Tsegulani fusesi yotentha popanda kuwononga kapena kudzipweteka nokha, ndipo potsiriza

3. Khazikitsani ma multimeter kumayendedwe olondola kuti muyese kupitiliza.

Zida Zofunikira

Mufunika zida zotsatirazi kuti muyese kupitiliza kwa fuse:

  • Zogwiritsa ntchito digito kapena analogi multimeter
  • Fuse yotentha yochokera ku chipangizo cholakwika
  • Kulumikiza mawaya kapena masensa
  • Chida chamagetsi
  • Ma screwdrivers amitundu yosiyanasiyana

Tsatirani njira zomwe zili pansipa kuti mumvetsetse zomwe muyenera kuchita kuti mudziwe ngati fuse yanu ili bwino. 

  1. Malo ndi kuchotsedwa kwa fuse yotentha: Ma fuse otentha amapezeka mosiyanasiyana ndi makulidwe osiyanasiyana. Onse ali ndi ntchito zofanana zamkati zomwe zimatanthauzira ntchito zawo. Mwachitsanzo, ngati mukugwiritsa ntchito chowumitsira, mungayambe ndi kuchotsa zitsulo zonse ndikuyang'ana fuse yotentha. Ndiye shunt mawaya ndi kuchotsa fusesi. Zolemba za fusezi zimatithandiza kuonetsetsa kuti chipangizocho sichinalumikizidwe ndi magetsi. Izi zimatithandiza kupewa kugunda kwa magetsi. Ma fuse ambiri amakhazikika bwino pagawo lolowera. Amayikidwa kumbuyo kwa chiwonetsero kapena gulu lowongolera (mwachitsanzo, mu uvuni wa microwave kapena chotsukira mbale). Mufiriji, ma fuse otentha amapezeka mufiriji. Ili kuseri kwa chivundikiro cha evaporator chifukwa cha chotenthetsera. (1)
  2. Momwe mungatsegule fusesi yotentha popanda kuwononga kapena kudzivulaza nokha: Kuti mutsegule fusesi, chotsani mawaya kuchokera kumaterminal. Kenako gwiritsani ntchito screwdriver kuchotsa zomangira zomwe zili ndi fuse yotentha m'malo mwake.
  3. Momwe Mungakonzekere Multimeter Kuti Muyese KupitilizaA: Musanasankhe kusintha fusesi yakale kapena ayi, muyenera kuyesa kupitiliza. Mufunika multimeter pa ntchitoyi. Nthawi zina ma fuse terminals amatsekedwa. Chifukwa chake, mungafunike kumasula chotsekekacho pochotsa zotsekereza kapena dothi. Kenako pukutani pang'onopang'ono ndi chinthu chachitsulo musanachite mayeso opitilira. (2)

    Kuti muyimbe ma multimeter, tembenuzani kuyimba kosiyanasiyana kukhala kotsika kwambiri kukana mu ma ohms. Pambuyo pake, yesani mamita polumikiza masensa pamodzi. Khazikitsani singano ku zero (kwa multimeter ya analogi). Kwa multimeter ya digito, tembenuzirani kuyimbayo kuti ikhale yotsika mtengo yokana. Kenako gwiritsani ntchito probe imodzi kukhudza matheminali a chida ndipo inayo kuti mugwire malo ena.

    Ngati kuwerenga ndi zero ohms, fusejiyo imakhala ndi kukhulupirika. Ngati dzanja silisuntha (kwa analogi) kapena ngati chiwonetsero sichikusintha kwambiri (pa digito), ndiye kuti palibe kupitiriza. Kupanda kupitiliza kumatanthauza kuti fusesi imawombedwa ndipo ikufunika kusinthidwa.

Kusintha fusesi yolakwika ndi malangizo okonzekera

Kuti mulowe m'malo mwa fuse yotentha, sinthani njira yochotsera monga pamwambapa. Kuti muchepetse chiopsezo chowombera fuse, gwiritsani ntchito zowongolera magetsi kuti muchedwetse mphamvu kapena magetsi. Kuti muchepetse kutsekeka, ndikofunikira kutseka fusesi ndikudzaza mabowo mu chipangizocho. Pomaliza, gwiritsani ntchito fuse wokhazikika.

Onani zina mwazolemba zathu pansipa.

  • Chizindikiro chopitilira ma multimeter
  • Momwe mungawerenge ohms pa multimeter
  • Momwe mungayesere capacitor ndi multimeter
