Yuav ua li cas sai sai kuaj qhov zoo ntawm multimeter fuse?
Rau cov engineers uas feem ntau cuam tshuam nrog "hluav taws xob", "kev nyab xeeb" yog ib txwm yog qhov tseem ceeb tshaj plaws. Thiab multimeter yog qhov tsim nyog ntsuas cov cuab yeej siv hluav taws xob, yog li kev nyab xeeb ntawm kev siv multimeter yog qhov tseem ceeb tshwj xeeb rau cov kws tshaj lij pem hauv ntej. Raws li peb txhua tus paub, multimeter muaj ib lub fuse nyob rau hauv qhov tam sim no los xyuas kom meej tias thaum kuaj qhov tam sim no, lub multimeter txuas nrog hauv series rau hauv Circuit Court. Thaum lub Circuit Court tam sim no tshaj qhov txwv lossis muaj qhov txaus ntshai tam sim no, lub fuse tuaj yeem qhib tau raws sijhawm kom ntseeg tau tias muaj kev nyab xeeb ntawm cov cuab yeej, tshwj xeeb tshaj yog cov neeg ua haujlwm.
Yuav ua li cas xaiv ib tug haum fuse?
Txhawm rau kom muaj kev nyab xeeb ntawm cov cuab yeej thiab cov neeg siv, nws yog ib qho tseem ceeb tshwj xeeb los xaiv lub fuse tsim nyog thiab muaj kev nyab xeeb. Lub Fluke multimeter tau nruab nrog cov fuses qub nrog lub zog siab thiab cov lus teb ceev ceev, kom ntseeg tau tias thaum muaj xwm txheej, lub cuab yeej tuaj yeem tiv thaiv qhov phom sij sai. Fluke tus thawj fuses yeej ib txwm tau tsim los raws li cov kev cai nruj uas ua tau raws li lossis tseem tshaj cov qauv kev nyab xeeb thoob ntiaj teb.
Qhov zoo ntawm fuses:
1. Rated voltage 1000V, 11A fuse tawg peev xwm 20KA. Tus thawj high-zog fuse yuav tsis tsuas yog tshuab nyob rau hauv lub nruam ntsuas tam sim no, tab sis kuj tam sim ntawd tshuab nyob rau hauv siab tam sim no tam sim no, kom ntseeg tau ceev teb thiab kev nyab xeeb.
2. Ceramic raj ntim nrog muaj zog arc extinguishing muaj peev xwm thiab kev ntseeg siab. Tus tsim tshwj xeeb tsim thawj high-zog fuse yog ntim nrog xuab zeb hauv. Thaum lub zog thiab qhov kub thiab txias uas ua rau muaj kev tawg, cov xuab zeb melts, absorbs lub zog, thiab cais cov huab cua uas xav tau rau kev tawg.
Kev phom sij ntawm kev siv cov fuses tsis raug:
Burnout ntawm cov cuab yeej; Cwj mem yaj; Cov neeg raug mob.
Kuv xav tsis nruab ib lub fuse dua li nruab ib lub fuse li niaj zaus!
Yuav ua li cas kom paub qhov zoo ntawm lub fuse sai sai?
Teem lub multimeter mus rau "Ω" txoj hauj lwm thiab siv ib qho kev sojntsuam xwb. Ntxig lub ntsaws rau hauv Ω qhov (socket) thiab siv qhov kawg ntawm kev sojntsuam mus txog rau hauv qhov "A" thiab "mA / uA" qhov sib npaug. Yog tias muaj kev nyeem ntawv, nws qhia tau tias lub fuse nyob rau hauv qhov zoo (qhov "A" yuav tsum nyeem 0-0.5 Ω, thiab lub qhov (socket) "mA / uA" yuav tsum nyeem ib ncig ntawm 10K Ω). Yog tias "OL" tshwm sim, nws qhia tau tias lub fuse raug hlawv.
