Cov yam ntxwv ntawm kev fuse yog tias qhov ntau dua qhov hluav taws xob los ntawm kev yaj, qhov luv luv ntawm lub sijhawm fusing
Lub fuse (fuse) yog hais txog cov khoom siv hluav taws xob uas siv hluav taws xob kub uas tsim los ntawm nws tus kheej los fuse cov yaj thiab tawg hauv Circuit Court thaum qhov tam sim no tshaj tus nqi teev tseg. Lub fuse yog ua raws li qhov tam sim no tshaj qhov teev tshwj xeeb rau ib lub sijhawm, cov yaj tau yaj los ntawm nws tus kheej tshav kub, yog li ua txhaum lub voj voos; tus tiv thaiv tam sim no ua los ntawm siv cov ntsiab cai no. Fuses tau siv dav hauv qhov siab thiab qis hluav taws xob faib hluav taws xob thiab tswj cov tshuab thiab raws li cov khoom siv hluav taws xob. Raws li luv luv Circuit Court thiab overcurrent tiv thaiv, nws yog ib qho ntawm cov khoom siv tiv thaiv feem ntau.
1) Lub fuse yog tus tiv thaiv tam sim no ua los ntawm kev siv lub ntsiab cai no los ua kom yaj nrog nws cov cua sov tsim tom qab tam sim no tshaj tus nqi teev tseg rau ib lub sijhawm, yog li txhawm rau Circuit Court. Fuses tau siv dav hauv qhov siab thiab qis hluav taws xob faib hluav taws xob thiab tswj cov tshuab thiab raws li cov khoom siv hluav taws xob. Raws li luv luv Circuit Court thiab overcurrent tiv thaiv, nws yog ib qho ntawm cov khoom siv tiv thaiv feem ntau.
Lub fuse yog kev tiv thaiv overcurrent. Lub fuse yog tsuas yog tsim ntawm yaj, yaj lub raj thiab muab tub lim sab nraud. Thaum siv, txuas rau lub fuse hauv series nrog tiv thaiv Circuit Court. Thaum tam sim no ntawm kev tiv thaiv Circuit Court tshaj qhov teev tus nqi, thiab tom qab qee lub sijhawm, lub tshav kub uas tsim los ntawm yaj nws tus kheej yuav fuse yaj thiab txiav tawm hauv Circuit Court, yog li tiv thaiv nws. nyhuv.
Cov cuab yeej hluav taws xob uas siv tus kav hlau los ua kom cov yaj kom tawg lub pob hluav taws xob yog sib txuas hauv cov kab hauv Circuit Court. Thaum lub sijhawm dhau los lossis luv luv-tam sim no dhau los ntawm yaj, cov yaj nws tus kheej yuav kub thiab fuse, uas ua tau zoo rau lub kaw lus fais fab, ntau yam khoom siv hluav taws xob thiab khoom siv hauv tsev. Tej yam kev tiv thaiv. Nrog kev rov qab ua dua lub sijhawm qeeb, thaum lub sijhawm dhau mus tam sim no me me, lub sijhawm fusing ntev; thaum lub overload tam sim no loj, lub sijhawm fusing yog luv. Yog li ntawd, nyob rau hauv qee qhov dhau ntawm qhov tam sim no kom txog rau thaum tam sim no rov rau qhov qub, lub fuse yuav tsis tshuab thiab koj tuaj yeem siv txuas ntxiv. Lub fuse feem ntau yog tsim los ntawm peb ntu: yaj, lub plhaub thiab kev txhawb nqa, thiab cov yaj yog qhov khoom tseem ceeb los tswj lub fusing yam ntxwv.
2) Cov yam ntxwv ntawm lub fuse:
1. Cov ntaub ntawv yaj tau muab faib ua cov khoom tawg qis thiab lub ntsiab lus melting. Tsawg melting point cov ntaub ntawv xws li cov hlau lead thiab cov hlau txhuas txhuas muaj qhov chaw melting tsawg thiab yooj yim rau fuse. Vim tias lawv cov kev tawm tsam loj, qhov sib hla qhov loj ntawm lub yaj yog qhov loj dua, thiab cov hlau ntau cov pa tso tawm thaum fuse. Nws tsuas yog haum rau fuse nrog qis tawg qhov muaj peev xwm. Ntaus ntawv.
High melting point cov ntaub ntawv xws li tooj liab thiab nyiaj muaj lub siab melting point thiab tsis yooj yim rau fuse, tab sis vim lawv qhov tsis kam tiv thaiv qis, lawv tuaj yeem ua rau hauv qhov chaw me me hla qhov loj dua qhov qis melting point melts, thiab tsim cov pa hlau tsawg dua thaum lub sijhawm fuse, uas yog haum rau qhov siab tawg Peev fuse. Cov duab ntawm cov melt tau muab faib ua ob hom: filament thiab ribbon. Hloov cov duab ntawm cov seem sib txawv tuaj yeem hloov pauv qhov cuam tshuam ntawm qhov fuse.
2. Lub fuse muaj qhov rov qab sib hloov lub sijhawm qeeb, qhov ntawd yog, thaum lub sijhawm tam sim no tseem me me, lub sijhawm fuse yog qhov ntev; thaum lub overload tam sim no loj, lub sijhawm fusing yog luv. Yog li ntawd, nyob rau qee qhov kev tswj ntawm ntau tshaj qhov tam sim no, thaum qhov tam sim no rov mus rau qhov qub, lub fuse yuav tsis tshuab thiab siv tau tas li. Lub fuse muaj ntau yam sib txawv ntawm cov fuse yam ntxwv ntawm cov kab nrig, uas tuaj yeem ua raws li qhov xav tau ntawm ntau hom kev tiv thaiv cov khoom.
3. Lub fuse raug muab nruab rau hauv Circuit Court kom ntseeg tau tias muaj kev nyab xeeb ntawm Circuit Court. Thaum lub Circuit Court tawg lossis muaj qhov txawv txav, qhov tam sim no tseem nce siab, thiab qhov nce tam sim no yuav ua rau qee qhov tseem ceeb lossis muaj nuj nqis hauv Circuit Court, lossis hlawv lub Circuit Court lossis tseem ua rau muaj hluav taws. Yog tias lub fuse raug txhim kho nyob hauv lub Circuit Court, lub fuse yuav fuse nws tus kheej thiab txiav tawm qhov tam sim no thaum qhov tam sim no nce mus rau ib qhov siab tsis meej, yog li tiv thaiv kev nyab xeeb kev ua haujlwm ntawm Circuit Court. Fuse txiav tawm qhov tam sim no, thiaj li tiv thaiv kev ua haujlwm zoo ntawm Circuit Court.
