Fuse Rating Ntawm Distribution Transformer
Qhov tseem ceeb ntawm qhov ntsuas fuse rau kev faib khoom transformers tsis tuaj yeem overstated. Lub tshuab hluav taws xob faib hluav taws xob yog lub luag haujlwm los txo qhov hluav taws xob hluav taws xob mus rau theem uas muaj kev nyab xeeb rau kev siv hauv tsev thiab kev lag luam. Lub fuse yog ib qho tseem ceeb ntawm lub transformer uas tiv thaiv nws ntawm kev puas tsuaj vim overcurrent faults. Yog li ntawd, xaiv txoj cai fuse rating yog ib qho tseem ceeb los xyuas kom meej qhov zoo ntawm lub transformer thiab tsis txhob raug nqi kho los yog hloov.
Qhov ntsuas fuse ntawm lub tshuab hluav taws xob faib hluav taws xob yog txiav txim siab los ntawm qhov siab tshaj plaws uas yuav tsum tau ua txhaum tam sim no uas tuaj yeem ntws los ntawm qhov hloov pauv. Nws yog ib qho tseem ceeb uas yuav tsum tau ua kom qhov loj me ntawm qhov ntsuas fuse kom haum rau qhov siab tshaj plaws tam sim no kom tiv thaiv lub fuse ntawm lub tshuab tsis tsim nyog lossis tsis tshuab thaum xav tau. Lub fuse uas tshuab sai dhau tuaj yeem ua rau lub zog tsis zoo, thaum lub fuse uas tsis tshuab tuaj yeem ua rau muaj kev puas tsuaj loj dua rau lub tshuab hloov pauv thiab, muaj peev xwm, tsim kom muaj kev nyab xeeb.
Feem ntau, muaj ob hom fuses siv nyob rau hauv kev faib khoom transformers: tshem tawm fuses thiab tam sim no-limiting fuses. Kev tshem tawm fuses yooj yim dua thiab tsis tshua kim tab sis yuav tsis muaj kev tiv thaiv txaus nyob rau hauv qhov teeb meem tam sim no. Tam sim no-limiting fuses, ntawm qhov tod tes, muaj zog dua thiab muab kev tiv thaiv zoo dua los ntawm kev cuam tshuam qhov txhaum tam sim no, txwv tsis pub muaj peev xwm rau kev puas tsuaj ntawm cov khoom siv hluav taws xob.
Thaum xaiv qhov ntsuas fuse rau kev faib khoom siv hluav taws xob, nws tseem ceeb heev uas yuav tsum tau txiav txim siab txog kev nce ntxiv rau yav tom ntej. Lub tshuab hluav taws xob tau teeb tsa los ua haujlwm rau thaj chaw qis qis yuav ua rau muaj kev loj hlob loj hauv lub sijhawm. Txhawm rau kom muaj kev loj hlob zoo li no, qhov ntsuas fuse yuav tsum raug xaiv kom tso cai rau kev ua txhaum tam sim no ntxiv yam tsis ua rau lub fuse tshuab sai dhau.
Hauv kev xaus, qhov ntsuas fuse ntawm cov khoom siv hluav taws xob faib hluav taws xob yog qhov tseem ceeb uas yuav tsum tau ua tib zoo saib xyuas kom muaj kev ua haujlwm zoo thiab tiv thaiv hluav taws xob tsis raug. Kev ntsuas qhov ntsuas fuse kom raug thiab xaiv hom fuse tsim nyog yog qhov tseem ceeb los lav qhov kev ntseeg siab tshaj plaws thiab tiv thaiv cov nqi kho lossis hloov pauv. Tsis tas li ntawd, xav txog qhov muaj peev xwm thauj khoom loj hlob thaum xaiv qhov ntsuas fuse tuaj yeem ua kom ntseeg tau tias lub tshuab hloov pauv tuaj yeem ua raws li cov kev xav tau hluav taws xob yav tom ntej ntawm thaj chaw pabcuam.
