Kev qhia xaiv thiab cov peev txheej xam cov tsheb fuses
Hauv cov txheej txheem ntawm kev tsim qauv ntawm lub hauv paus ntawm tag nrho cov tsheb architecture, kev xaiv ntawm cov fuses yog qhov tseem ceeb uas tsis paub thiab kev txawj txuag rau cov xaim hlua hluav taws xob system engineers. Rau lub hauv paus ntawm kev kawm ntau npoj yaig' kev tshawb fawb ntawm kev xaiv ntawm cov tsheb fuses, Anna ua ke nrog nws tus kheej kev lag luam los ua kev soj ntsuam thiab cov ntsiab lus ntawm kev xaiv cov ntsiab lus thiab cov hau kev ntawm cov tsheb fuses.
1 Lub tshuab ua haujlwm ntawm lub fuse
Ua ntej peb xaiv thiab tsim lub fuse, peb yuav tsum nkag siab txog ob lub ntsiab lus tseem ceeb: 1. Vim li cas peb thiaj li yuav tsum tau ntxiv lub fuse rau txoj hlua txuas ntawm lub xov hlau? 2. Dab tsi yog qhov ua haujlwm ua haujlwm ntawm lub fuse?
1 Vim li cas fuse ntxiv rau hauv Circuit Court?
Lub fuse yog lub zog hluav taws xob teb, yog ib qho hluav taws xob tiv thaiv cov xov hlau. Yog tias tsis muaj cov fuse hauv Circuit Court, tom qab ntawd ib zaug Circuit Court dhau mus, thaum lub sijhawm luv luv Circuit Court tshwm sim, qhov tam sim no ntws los ntawm cov xaim ntau tshaj qhov nqa tawm tam sim no ntawm cov hlau, thiab cov hlau tsis cuam tshuam, ua rau muaj kev nyab xeeb (tsheb hlawv) Cov. Nws yog tsim nyog kom nco ntsoov tias txoj haujlwm ntawm fuse yog qhov tseem ceeb los tiv thaiv cov hlau.
Cov xwm txheej tshwm sim ntawm cov hlau yog muaj nyob hauv daim duab hauv qab no:
Ntawm no dua, hauv Circuit Court, lub fuse tuaj yeem tiv thaiv cov xov hlau tom qab fuse, yog li cov fuse yuav tsum tau muab tso kom ze rau qhov kev xa hluav taws xob kom sai li sai tau. Yog tias qhov kev ncua deb mus deb, xav txog teeb tsa kev tiv thaiv qib siab.
2 Dab tsi yog qhov haujlwm ua haujlwm ntawm lub fuse?
Ua ntej xaiv lub fuse, nws yog ib qho tseem ceeb kom nkag siab lub luag haujlwm tseem ceeb thiab kev ua haujlwm ntawm lub fuse, thiab nws yog qhov yuav tsum tau ua ua ntej rau kev nkag siab cov qauv tsim rau xaiv lub peev xwm fuse.
Lub tshuab ua haujlwm ntawm lub fuse yog tias thaum lub Circuit Court luv luv, nws tuaj yeem raug tshuab hauv lub sijhawm thaum cov xaim yog haus luam yeeb thiab ntes hluav taws, thiaj li txiav tawm ntawm Circuit Court thiab tiv thaiv cov hlau los ntawm hlawv thiab ua rau tshwm sim ntawm lub qhov hluav taws xob ntawm tsheb. Yog li, nws yog qhov tsim nyog los nruab lub pob hluav taws xob (fuse) hauv txhua lub zog txuas rau kab kev tiv thaiv.
Cov haujlwm ua haujlwm tshwj xeeb ntawm kev fuse yog raws li hauv qab no:
Lub fuse muaj qhov muaj qhov tsis kam, tus neeg xyuas pib yuav tsim kom muaj cua sov thaum hluav taws xob tam sim no, thiab lub tshav kub hluav taws xob nce nrog lub sijhawm, thiab cov hluav taws xob tam sim no thiab cov kuj tseem nce cov hluav taws xob kub ceev. Tus qauv ntawm fuse thiab nws cov teeb tsa txiav txim siab lub cua sov dissipation ceev.
Yog hais tias: tshav kub tiam ceev< tshav="" kub="" dissipation="" ceev,="" lub="" fuse="" yuav="" tsis="">
Yog hais tias: tshav kub tiam ceev=tshav kub dissipation ceev, nws yuav tsis fuse rau lub sijhawm ntev;
Yog tias: tshav kub tiam ceev> tshav kub dissipation ceev, tshav kub accumulates, thiab lub fuse tawg thaum lub kub nce siab tshaj qhov melting point ntawm lub fuse.
Qhov no yog li cas cov fuse ua haujlwm.
Hauv qhov tsim hluav taws xob hauv Circuit Court, lub fuse raug xaj rau ntawm lub zog sab nraud ntawm Circuit Court. Thaum lub load dhau ntawm kev hla, cov cuab yeej lossis cov xov hlau luv luv, lub tshav kub uas tsim los ntawm qhov tam sim no nce mus txog lub chaw melting nyob rau hauv qhov me me ntawm qhov fuse hla qhov chaw thiab yaj, tiv thaiv cov xov hlau ntawm Circuit Court. Daim duab ntawm daim duab ntawm lub fuse.
Hais txog lub tshuab ntawm cov fuse thiab xov hluav taws xob txuam, Kuv kuj tau sau ib tsab xov xwm ua ntej. Yog tias koj txaus siab, koj tuaj yeem nyeem nws (qhov sib txuam tsim ntawm lub fuse thiab xaim).
2 Lub hom fuse thiab qhov ntsuas tseem ceeb
Tom qab kev nkag siab cov txheej txheem ua haujlwm ntawm lub fuse, peb kuj yuav tsum paub txog hom thiab yam tseem ceeb ntawm kev fuse txhawm rau txhawm rau ua qhov kev xaiv tseeb ntawm lub fuse.
Hauv kev tsim qauv ntawm kev kho tsheb, cov hom fuse suav nrog fuse, fuse, thiab breaker Circuit Court. Qhov tshwj xeeb siv ib puag ncig muaj raws li nram no:
1) Fuse
Lub ntsiab lus tiv thaiv ntawm kev fuse yog fuse, uas yog kev cob cog rau hauv cov kab ntau hauv Circuit Court nws tiv thaiv. Lub fuse yog cov khoom siv ib zaug xwb, thov xyuam xim rau:
Tom qab fuse tshuab, tus ua txhaum thiaj li yuav tsum pom ua ntej. Thiab tau txiav txim kiag li.
Thaum hloov lub fuse, nws yuav tsum yog tib yam li qhov tseem ceeb tshaj plaws. Hauv qhov tshwj xeeb, ib qho fuse uas muaj lub peev xwm loj dua li qhov teev tshwj xeeb tsis tuaj yeem siv, txwv tsis pub cov ntsiab lus tiv thaiv yuav ploj.
Kev tiv tauj tsis zoo ntawm tus fuse nrog thiab lub fuse yuav ua rau voltage poob thiab cov cua sov tiam. Yog li ntawd, them nyiaj tshwj xeeb rau kev kuaj xyuas kom muaj oxidation thiab av. Yog tias muaj cov av thiab oxides, nws yuav tsum tau txhuam nrog cov ntawv nplaum kom zoo rau kev sib cuag.
2) Kab cuav
Cov kab hluav taws xob yooj yim feem ntau txuas nrog rau lub hwj chim kab thiab kab nrog lub loj tam sim no los tiv thaiv tag nrho cov kab lossis tseem ceeb cov voj voog. Piv txwv, Beijing Cherokee muaj tsib xaim xaim xaim thaiv los tiv thaiv lub xov hluav taws xob, ua ntej rhaub hluav taws xob, lub teeb huab, lub teeb thiab ntu txuas nrog.
3) Circuit Court breaker
Circuit breakers siv nyob rau hauv Circuit Court uas nquag raug overload thaum lub sijhawm ua haujlwm. Lub hauv paus ntsiab lus yog siv bimetallic ib daim hlab kom sov thiab deform los cais cov neeg. Muaj ob qho tseem ceeb ntawm cov hluav taws xob Circuit Court, 1. Kev rov kho tus kheej hluav taws xob Circuit Court: Txiav kev txiav tawm dhau thiab rhuav, thiab rov pib kho tom qab txias, thiab rov ua dua kom txog thaum lub Circuit Court tsis tshaj. 2 Nias lub xov hluav taws xob rov ua txhaum kev sib tsoo: Tom qab daws teeb meem, koj yuav tsum nias lub khawm kom rov teeb tsa tus kheej.
Rau cov hom tshwj xeeb thiab qhov tseem ceeb ntawm ntau yam fuses, koj tuaj yeem mus ncaj qha rau lub vev xaib fuse kom paub cov khoom siv phau ntawv ntawm lub fuse. Tam sim no, txoj kev ua lag luam loj rau fuses yog Dissmann Fuse (www.dissmannfuse.com)
