Yuav ua li castiv thaiv cov xov hlau thiab cableslos ntawm ntes hluav taws vim overloaded hlau!
Thaum lub sijhawm ua haujlwm ntawm cov hlau thiab cable, cov cua sov yuav raug tsim tawm vim muaj qhov ua haujlwm tsis zoo.Qhov tsis kam ntawm cov hlau feem ntau me me, thiab nws lub zog cua sov tuaj yeem qhia tau los ntawm cov mis q = I^2R.q = I^2R qhia tau hais tias: rau ib daim hlau hauv kev siv tiag tiag (R yog qhov tsis tu ncua), qhov ntau dua tam sim no dhau los ntawm cov xaim, lub zog cua sov ntau dua;yog tias qhov tam sim no tas li, lub zog cua sov ntawm cov hlau kuj tseem nyob tas li..Cov cua sov tso tawm thaum lub sijhawm ua haujlwm yuav raug nqus los ntawm cov hlau nws tus kheej, ua rau cov hlau kub nce.Txawm hais tias cov hlau tsis tu ncua nqus cov cua sov tso tawm los ntawm qhov tam sim no thiab ua haujlwm thaum lub sijhawm ua haujlwm, nws qhov kub thiab txias yuav tsis nce mus txog qhov kawg.Vim hais tias cov hlau yog nqus cua sov, nws kuj tseem tso tawm cua sov mus rau lub ntiaj teb sab nraud.Qhov tseeb qhia tau hais tias qhov kub ntawm cov hlau maj mam nce tom qab cov hlau yog energized, thiab thaum kawg qhov kub thiab txias yog tas li ntawm ib qho chaw.Ntawm qhov chaw tas mus li no, qhov nqus cua sov thiab cov cua sov tso tawm lub zog ntawm cov hlau yog tib yam, thiab cov hlau nyob hauv lub xeev ntawm thermal equilibrium.Muaj kev txwv rau lub peev xwm ntawm cov conductors kom tiv taus kev ua haujlwm kub dua, thiab kev ua haujlwm dhau qhov kub siab tshaj plaws tuaj yeem ua rau muaj kev phom sij.Qhov kub siab tshaj plaws no ib txwm sib raug rau qee qhov siab tshaj plaws tam sim no, thiab cov xaim khiav dhau qhov siab tshaj plaws tam sim no yog overloaded.Overloading cov hlau ncaj qha nce qhov kub ntawm cov hlau nws tus kheej thiab nws cov khoom nyob ib puag ncig.Qhov kub thiab txias yog qhov ncaj tshaj plaws ua rau muaj hluav taws kub.
Overload ua rau lub rwb thaiv tsev txheej ntawm ob-strand xov hlau, ua rau luv luv Circuit Court, hlawv cov khoom, thiab ua rau hluav taws.Ob-strand xov hlau yog sib cais los ntawm cov txheej insulating ntawm lawv, thiab cov overload yuav soften thiab rhuav tshem cov insulating txheej, uas yuav ua rau cov kev sib cuag ncaj qha ntawm ob-strand nyob ntawm tej ua rau ib tug luv luv Circuit Court thiab hlawv cov khoom.Nyob rau tib lub sijhawm, qhov kub thiab txias tsim los ntawm qhov siab tam sim no ntawm lub caij luv luv ua rau cov kab hluav taws kub thiab fuse, thiab cov hlaws uas tau tsim los ntawm cov khoom siv hluav taws xob poob rau cov khoom siv hluav taws xob thiab ua rau hluav taws kub.Lub overload kub nce tuaj yeem ncaj qha ignites nyob ze combustibles.Lub tshav kub hloov ntawm lub overloaded hlau tsub kom qhov kub ntawm cov nyob ze combustibles.Rau cov combustibles nyob ze nrog cov ntsiab lus ignition qis, nws muaj peev xwm ignite lawv thiab ua rau hluav taws.Qhov kev phom sij no tshwj xeeb tshaj yog nyob rau hauv cov tsev khaws khoom uas cov khoom siv hluav taws xob tau khaws cia thiab cov tsev nrog cov khoom siv yooj yim thiab cov khoom siv hluav taws xob.
Overloading kuj nthuav tawm cov kev sib txuas hauv kab rau overheated tej yam kev mob, uas accelerates tus txheej txheem ntawm oxidation.Oxidation ua rau nyias oxide zaj duab xis uas tsis yooj yim conductive ntawm cov ntsiab lus sib txuas, thiab cov oxide zaj duab xis ua rau muaj kev tiv thaiv ntawm cov ntsiab lus sib cuag, uas ua rau muaj hluav taws thiab lwm yam tshwm sim, ua rau hluav taws kub.
Yog li, yuav ua li cas tiv thaiv hluav taws los ntawm overloading ntawm cov xov hlau thiab cables?
1. Nyob rau hauv cov txheej txheem ntawm kev tsim kab, lub peev xwm ntawm qhov chaw yuav tsum raug kuaj xyuas kom raug, thiab qhov muaj peev xwm ntxiv cov peev txheej tshiab yav tom ntej yuav tsum tau txiav txim siab tag nrho, thiab cov hom hlau tsim nyog yuav tsum raug xaiv.Yog tias lub peev xwm loj, cov xov hlau tuab yuav tsum tau xaiv.Circuit Court tsim thiab tsim nyog xaiv yog cov kauj ruam tseem ceeb los tiv thaiv overload.Yog tias tus qauv tsim raug xaiv tsis raug, yuav muaj kev phom sij zais cia uas nyuaj rau kho.Qee qhov haujlwm me me thiab qhov chaw tsis ua tib zoo tsim thiab xaiv.Nws yog qhov txaus ntshai heev los xaiv thiab nteg cov kab ntawm qhov xav tau.Cov khoom siv hluav taws xob tshiab thiab cov khoom siv hluav taws xob yuav tsum xav txog tag nrho cov kabmob muaj peev xwm ntawm cov kab qub.Yog hais tias tus thawj kab tsis tau raws li qhov yuav tsum tau, nws yuav tsum tau redesigned thiab reconstructed.
2. Cov kab yuav tsum tau tsim thiab tsim los ntawm cov kws tsim hluav taws xob tsim nyog raws li cov lus qhia tshwj xeeb.Cov txheej txheem tso ntawm cov kab ncaj qha cuam tshuam rau lub tshav kub dissipation ntawm cov xov hlau.Feem ntau hais lus, cov kab nteg yuav tsum tsis txhob dhau los ntawm cov khoom siv yooj yim, combustible thiab stacking, uas yuav ua rau tsis zoo cua sov dissipation ntawm cov xov hlau, cov cua kub tsub zuj zuj, muaj peev xwm ntawm igniting cov ntaub ntawv uas nyob ib ncig ntawm combustible, thiab ua rau muaj kev pheej hmoo ntawm hluav taws los ntawm overloading;Cov kab nteg nyob rau hauv lub qab nthab ntawm kev kho kom zoo nkauj ntawm pej xeem kev lom zem qhov chaw yuav tsum tau tiv thaiv los ntawm steel kav, thiaj li hais tias lub qab nthab yog sib cais los ntawm cov kab, thiab txawm yog hais tias muaj molten hlaws nyob rau hauv overload, luv luv Circuit Court, thiab lwm yam, nws yuav tsis poob. tawm, thiaj li zam tau hluav taws.
3. Txhim khu kev tswj fais fab, tsis txhob muaj kev sib txuas thiab xaim, thiab siv cov xov tooj ntawm tes nrog ceev faj.Kev xaim hluav taws xob tsis sib xws, kev xaim tsis sib xws, thiab kev siv cov xov tooj ntawm tes yog qhov ua tau ntxiv cov khoom siv hluav taws xob rau qee ntu ntawm txoj kab, ua kom cov nqi tam sim no thiab tej zaum yuav ua rau overload.Lub qhov (socket) jacks ntawm lub xov tooj ntawm tes yog pom tseeb ntau dua li cov sockets ruaj khov ntawm phab ntsa.Yog tias siv cov khoom siv hluav taws xob ntau dhau ntawm lub qhov (socket) ntawm lub xov tooj ntawm tes, qhov qub Circuit Court yuav tsis tuaj yeem tiv taus.Rau cov cuab yeej siv hluav taws xob siab thiab cov khoom siv hluav taws xob, cov kab sib cais yuav tsum tau teeb tsa, thiab cov khoom siv txawb yuav tsum tsis txhob siv los ua cov khoom siv hluav taws xob.
