Dab tsi yog qhov teeb meem thaum fuse nyob hauv tsev? Yuav ua li cas siv tus mullamatal ntsuas qhov tam sim no?
Nyob rau hauv ib txwm muaj xwm txheej, cov xwm txheej hauv qab no tuaj yeem ua rau lub fuse kom tshuab:
① hlau sib txuas kev sib txuas hauv Circuit Court.
Luv luv luv ntawm Circuit Court hauv Circuit Court.
③ Overloading, uas yog, siv cov khoom siv hluav taws xob nrog qhov kev tshaj tawm tam sim no ntawm qhov ntsuas hluav taws xob.
④ Tsis yog ntawm rab riam hloov. Thaum sib txuas ntawm rab riam hloov, yog tias cov hlau xaus yog tsis nruj thiab lub fuse yog tsis ua rau muaj kev sib koom ua ke kub thiab tshav kub thaum siv yuav tshuab li.
Qhov thib ob lo lus nug yog: Yuav ua li cas siv tus multimeter los ntsuas qhov tam sim no?
Thaum siv ntau qhov kev ntsuas qhov tam sim no, kho cov hloov pauv ntawm ntau qhov puv rau ACTIVE thiab ntau yam. Koj tuaj yeem kwv yees thawj zaug ntawm tag nrho cov khoom siv hluav taws xob hauv tsev. Tom qab ntawd, kho cov ntau sib txuam rau ntau qhov ntau dua los yog sib npaug ntawm cov hluav taws xob hauv tsev thiab txuas nws hauv cov kab hauv Circuit Court rau kev ntsuas. (Ua tib zoo saib xyuas kev nyab xeeb kom tiv thaiv hluav taws xob. Nws tsis pom zoo rau qhov tsis- kws tshaj lij ua haujlwm.)
Txij li tam sim no ntau ntawm cov ntau yam yog qhov me me, nws raug pom zoo kom siv cov khoom siv tshwj xeeb nrog ntau dua li ib lub clamper ammeter. Tsuas yog muab ib qho -} theem cov xaim xaim hluav taws xob tau ntsuas hauv lub tshuab clamp ntawm cov khoom siv tshiab uas tsim nyog tam sim no ntawm lub clamp ammeter). Tus lej naj npawb ntawm lub sijhawm no yog qhov tam sim no (hauv amperes) ntawm kev siv hluav taws xob hauv lub sijhawm no.
Cov laj thawj rau lub fuse tshuab yog tsis muaj dab tsi ntau tshaj overloading thiab luv Circuit Court. Fuses (fuse traves) muaj tus neeg ntaus nqi, thiab lawv yuav tshuab thaum lub nra tau dhau. Thaum cov khoom siv hluav taws xob tsis tshaj cov kev siv hluav taws xob feem ntau ntawm cov fuse, muaj ib qho teeb meem nrog ib tus neeg Circuit Court. Thiab qee cov multimeters tib neeg tsuas yog ntsuas DC tam sim no thiab tsis tuaj yeem txuas rau hauv cov ntawv rau AC Circuit Court. Feem ntau, rau kev saib xyuas, nws yog ib qho yuav tsum tau qhib Circuit Court nyob hauv zos thiab tom qab ntawv xyuas lub zog muab khoom. Yog tias lub fuse tsis yog bling tom qab ib feem yog disconnected, qhov kev txhaum ntau yuav txiav txim siab. Yog tias lub fuse tseem tawg tom qab tag nrho cov khoom siv tau raug txiav tawm, nws tuaj yeem txiav txim siab tias muaj teeb meem nrog Circuit Court. Disconnect lub hwj chim muab thiab lub nra, thiab siv ntau yam ntawm ntau ntau ntawm kev ntsuas qhov tsis kam ntawm cov xov hlau. Yog tias nws yog kev coj ua, nws txhais tau tias muaj teeb meem nrog Circuit Court, thiab tsuas yog kev daws teeb meem yog los hloov cov xov hlau lossis rewire. Nws raug nquahu kom caw cov hluav taws xob kev txawj rau kev saib xyuas thiab tsis txhob ua haujlwm casually. Tom qab tag nrho, hluav taws xob yog "Tsov txaus ntshai", thiab tsis ua cov haujlwm phom sij.
