Thaum twg high voltage fuseblows, qhov no yog qhov peb yuav tsum tau them sai sai rau. Paub qhov ua rau lub tshuab yog qhov zoo heev rau peb rau nruab thiab siv lub tshuab hluav taws xob siab.
High-voltage fuses feem ntau tshuab hauv cov xwm txheej hauv qab no:
1.High-voltage fuseis me me, ntsia tsis raug, thiab cua tshuab vim tsis muaj zog txhua yam. Feem ntau, tsuas yog ib theem tawg. Feem ntau, tsis muaj qhov pom tseeb arc kab. Hloov lub high-voltage fuse tuaj yeem rov pib xa hluav taws xob.
2. Lub high-voltage fuse ntawm lub transformer yog cua tshuab vim nyob rau hauv lub faults, feem ntau yog ob-theem fuses. Hauv qhov no, qhov laj thawj yuav tsum tau tshawb pom ua ntej lub zog xa hluav taws xob tuaj yeem rov pib dua. Thaum lub transformer yog nyob rau hauv faulty, nws feem ntau ua rau cov roj los ntawm lub seam ntawm lub loj cover ntawm cov roj tank, cov roj txhaj qhov, thiab lwm yam, qhib cov roj txhaj lub qhov npog thiab tsis hnov tsw ntawm oily pa luam yeeb, thiab txiav txim seb lub transformer twb hlawv raws li oily pa luam yeeb, thiab seb nws puas siv tau. Yog tias tsis muaj qhov kos npe pom tseeb, qhov laj thawj yuav tsum tau tshawb pom ua ntej nws muab tso rau hauv kev ua haujlwm.
3. Lub high voltage fuse yog tshuab vim tej thaj chaw deb Circuit Court luv los yog overload. Vim lub sij hawm ntev ntawm lub fuse thiab kev koom tes ntawm lub siab thiab tsis tshua muaj hluav taws xob fuses, lub siab thiab qis voltage fuses tuaj yeem tshuab tib lub sijhawm. Nyob rau hauv cov ntaub ntawv no, muaj ib tug kab ntawm arc teeb thiab lub melting point ntawm lub fuse nyob rau hauv lub melting raj thiab lub porcelain yas dhos. Thaum ua tiav, siv lub megger los ntsuas qhov rwb thaiv tsev ntawm qhov siab thiab qis voltage transformers rau hauv av thiab nruab nrab ntawm lawv, thiab siv lub ohmmeter los ntsuas qhov conduction thiab DC tsis kam sib npaug ntawm qhov siab thiab qis voltage windings. Yog tias tsis muaj qhov txawv txav, tshem tawm tag nrho cov fuses ntawm sab qis-voltage, hloov cov fuses siab kom xa hluav taws xob, mloog seb lub suab ntawm lub tshuab hluav taws xob puas zoo li qub, thiab ntsuas seb qhov voltage thib ob yog qhov sib npaug. Yog tias tsis muaj teeb meem, rov pib xa hluav taws xob mus rau qhov tsis tshua muaj hluav taws xob.
