Fuse vs Circuit Breaker

Hluav taws xob yog qhov tseem ceeb hauv peb tsev neeg thiab kev lag luam. Nrog nws cov txiaj ntsig ntau, tseem hluav taws xob yuav ua rau muaj teeb meem hauv txhua daim ntawv thov yog tias tsis tswj kom raug. Ib qho khoom siv hluav taws xob ntau dhau tuaj yeem ua rau txhua yam khoom siv lossis cov tshuab txuas nrog lub zog hluav taws xob; tej zaum txawm ua rau kev ploj tuag. Ob lub fuses thiab Circuit Court breakers yog cov cuab yeej siv los tiv thaiv kev puas tsuaj vim hluav taws xob overloads. Lub tswv yim tom qab cov yam ntxwv ntawm kev nyab xeeb zoo li fuses thiab cov hluav taws xob hluav taws xob yog kom tshem tawm cov hluav taws xob sab hauv los ntawm lub hwj chim loj, thaum muaj hluav taws xob ntau dhau los yog tam sim no sim hla dhau qhov ntawd.

Ntau txog Fuses

fuses yog cov khoom siv txuas nrog txuas mus rau ib lub voj voog nyob nruab nrab ntawm cov khoom siv hluav taws xob thiab hluav taws xob sab hauv. Tag nrho cov hluav taws xob fuses qhia txog cov hauv paus ntsiab lus ntawm kev ua haujlwm, tab sis muaj ntau yam kev hloov pauv thiab hloov kho kom haum raws li qhov xav tau ntawm cov hluav taws xob. Lub fuse muaj xws li ib tug nyias conduction hlau nrog tshwj xeeb thermal zog txuas nrog ob terminals ntawm qhov kawg.

Txhua tus neeg xyuas pib qhia tsawg kawg ib qho kev tiv thaiv me me rau qhov ntws ntawm tam sim no, thiab cov tam sim no heats li tus neeg xyuas pib. fuses yog tsim los xws li hais tias, thaum tus nqi ntawm cov tam sim no dhau los ntawm cov hlau nyias dhau qhov kev tso cai, cov cua sov tsim ua rau lub melting ntawm cov hlau hlau, disconnecting lub sab hauv Circuit Court los ntawm lub hwj chim qhov chaw. Cov yam ntxwv hluav taws xob ntawm cov fuses raug ntsuas, thiab cov khoom siv hluav taws xob yuav tsum ua haujlwm nyob rau hauv cov nqi ntsuas no, kom ua haujlwm yam tsis muaj kev cuam tshuam.

Fuses muaj qhov ntsuas tam sim no (IN), uas yog qhov siab tshaj plaws tso cai tam sim no ua ntej kev tawg. Rated Voltage yog qhov tsawg kawg nkaus voltage uas lub Circuit Court yuav qhib vim melting ntawm cov hlau. Kub muaj feem xyuam rau cov khoom siv; yog li qhov voltage uas lub fuse tshuab. Yog li ntawd, qhov ntsuas kub kuj tseem ntsuas rau lub fuse thiab cim rau ntawm pob ntawm lub fuse.

Qhov loj ntawm lub fuse yuav txawv ntawm ib centimeters mus txog ib nrab ib 'meter'. Tsis tas li ntawd, lub ntim kuj hloov raws li daim ntawv thov. Thaum lub fuse raug tshuab nws yuav tsum tau hloov nrog ib qho tshiab.

Ntau txog Circuit Breakers

Ib lub tshuab hluav taws xob yog qhov hloov pauv tsis siv neeg uas tsim los siv cov txheej txheem electromechanical los tiv thaiv lub zog dhau kev puas tsuaj lossis luv luv. Lub Circuit Court breaker muaj ib tug solenoid nyob rau hauv, thiab nws yog khaws cia nyob rau hauv ib tug tej yam voltage theem, kom lub triggering mechanism nyob rau hauv sib npaug. Thaum pom qhov ua txhaum cai hauv Circuit Court, xws li overload lossis luv luv Circuit Court, qhov hloov pauv tau tshwm sim, thiab tam sim no ntws tawm. Tom qab kev daws qhov teeb meem cuam tshuam hauv qhov hluav taws xob, qhov hluav taws xob hluav taws xob tuaj yeem hloov rov qab mus rau dua.

Zoo li fuses, Circuit Court breakers kuj tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab pob khoom, tshwj xeeb rau cov kev xav tau ntawm cov hluav taws xob. Lawv muaj qhov tam sim no thiab qhov ntsuas hluav taws xob qhia qhov siab tshaj plaws tam sim no thiab qhov hluav taws xob.

Dab tsi yog qhov txawv ntawm Fuses thiab Circuit Breakers?

• Lub fuse yog cov cuab yeej ua haujlwm ntawm cov khoom siv hluav taws xob thiab thermal ntawm cov khoom siv, thaum lub tshuab hluav taws xob yog cov khoom siv ua haujlwm ntawm cov qauv siv hluav taws xob.

• Ib zaug siv lub fuse yuav tsum tau hloov tab sis lub Circuit Court breaker tuaj yeem rov qab siv tau tom qab kho qhov txhaum hauv qhov system.

• Fuses muab kev tiv thaiv tsuas yog lub hwj chim overloads, thaum Circuit Court breaker muaj kev tiv thaiv tiv thaiv hluav taws xob overloads thiab luv circuits (voltage imbalances).
