Yuav Ua Li Cas Ua Kev Ntsuas Ceev kom kuaj xyuas qhov xwm txheej ntawm Multimeter Fuse
Rau cov engineers uas feem ntau cuam tshuam nrog hluav taws xob, kev nyab xeeb yog qhov tseem ceeb tshaj plaws. Thiab ib lub multimeter yog ib qho tseem ceeb rau kev ntsuam xyuas cov cuab yeej hluav taws xob, yog li kev nyab xeeb ntawm kev siv multimeter yog qhov tseem ceeb tshwj xeeb rau cov engineers pem hauv ntej. Raws li peb txhua tus paub, multimeter muaj qhov ua tau - nyob rau hauv fuse nyob rau hauv hom 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 qhov hluav taws xob tam sim no dhau ntawm tus qauv lossis muaj qhov txaus ntshai tam sim no, lub fuse tuaj yeem raug txiav tawm hauv lub sijhawm kom muaj kev nyab xeeb ntawm cov cuab yeej, tshwj xeeb tshaj yog tus neeg teb xov tooj.
Yuav ua li cas xaiv lub fuse tsim nyog?
Nws yog ib qho tseem ceeb tshwj xeeb los xaiv lub fuse tsim nyog thiab muaj kev nyab xeeb los xyuas kom muaj kev nyab xeeb ntawm cov cuab yeej thiab cov neeg siv. Fluke multimeters tau nruab nrog siab -zog, ultra high-speed teb thawj fuses, kom ntseeg tau tias thaum muaj xwm txheej, cov cuab yeej tuaj yeem tiv thaiv kev phom sij sai. Fluke thawj fuses yeej ib txwm tau tsim los raws li cov kev cai nruj uas ua tau raws li lossis tseem dhau cov qauv kev nyab xeeb thoob ntiaj teb.
Qhov zoo ntawm Fluke fuses:
1. Rated voltage 1000V, 11A fuse tawg peev xwm 20KA. Tus thawj siab - lub zog fuse tuaj yeem tsis tsuas yog yaj hauv qhov ntsuas tam sim no, tab sis kuj tam sim ntawd yaj nyob rau hauv siab tam sim no tam sim no, ua kom cov lus teb ceev ceev thiab kev nyab xeeb.
2. Ceramic raj ntim, muaj zog arc extinguishing muaj peev xwm, muaj kev ntseeg siab. Tus tsim tshwj xeeb tsim thawj siab - lub zog fuse yog ntim nrog xuab zeb hauv. Thaum lub zog thiab qhov kub thiab txias uas tuaj yeem ua rau tawg, cov xuab zeb melts, absorbs lub zog, thiab cais cov huab cua uas xav tau rau kev tawg thiab combustion.
Kev phom sij ntawm kev siv lub fuse tsis raug:
Cov cuab yeej hlawv tawm; Kev sojntsuam melts; Cov neeg raug mob.
Kuv xav tsis nruab ib lub fuse dua li ib txwm!
Yuav ua li cas kom paub qhov zoo ntawm fuses sai sai?
Teem lub multimeter rau "Ω" txoj hauj lwm, tsuas yog siv ib qho kev sojntsuam, ntxig lub ntsaws rau hauv Ω socket, thiab ntxig tus cwj mem rau hauv lub qhov "A" thiab "mA / uA" raws. Yog tias muaj kev nyeem ntawv, nws qhia tau hais tias lub fuse zoo (qhov "A" nyeem ntawv yuav tsum yog 0-0.5 Ω, thiab "mA / uA" socket nyeem yuav tsum nyob ib ncig ntawm 10K Ω). Yog hais tias nws qhia "OL", nws qhia tau hais tias lub fuse yog burnt tawm.
