Txoj Cai Ua Haujlwm ntawm Circuit Breaker

Lub tshuab hluav taws xob feem ntau muaj cov kab sib tiv tauj, ib qho arc - tua hluav taws xob, lub tshuab ua haujlwm, ib qho chaw mus ncig, thiab qhov chaw kaw.

Nyob rau hauv qhov kev tshwm sim ntawm ib tug luv luv Circuit Court, lub magnetic teb generated los ntawm cov loj heev tam sim no (feem ntau yog 10 mus rau 12 lub sij hawm tus nqi ntsuas) overcomes lub zog ntawm ib tug counter- caij nplooj ntoos hlav; chav tsev mus txawv tebchaws ces actuates lub operating mechanism, ua rau lub hloov mus rau instantaneously. Thaum lub sij hawm overloading, qhov nce tam sim no intensifies thermal cua sov; ib tug bimetallic sawb deforms mus rau ib tug tshwj xeeb, yog li ua rau cov kev khiav hauj lwm mechanism (qhov siab dua qhov tam sim no, lub sij hawm teb luv luv).

Kuj tseem muaj hluav taws xob- hom hluav taws xob hluav taws xob, uas siv cov hloov pauv tam sim no los ua piv txwv qhov ntsuas tam sim no hauv txhua theem. Los ntawm kev sib piv cov txiaj ntsig no tawm tsam qhov pib ua ntej, lub microprocessor kuaj pom qhov tsis txaus ntseeg tam sim no thiab teeb tsa lub teeb liab, ua rau lub tshuab hluav taws xob mus ncig ua haujlwm rau kev ua haujlwm.

Lub luag haujlwm tseem ceeb ntawm lub tshuab hluav taws xob hluav taws xob yog txhawm rau txuas thiab tshem tawm cov khoom siv hluav taws xob, nrog rau kev cuam tshuam cov hluav taws xob cuam tshuam, yog li tiv thaiv kev sib tsoo ntawm kev sib tsoo thiab ua kom muaj kev nyab xeeb. High-voltage circuit breakers, tshwj xeeb tshaj yog, yuav tsum tau cuam tshuam cov arcs uas muaj qhov voltages ntawm 1500 V thiab cov tam sim no ntawm 1500 txog 2000 A- arcs uas tuaj yeem ncav cuag 2 meters ntev tsis tau txuas ntxiv hlawv yam tsis muaj kev tua. Yog li ntawd, kev tua hluav taws zoo ntawm cov arcs yog ib qho kev sib tw tseem ceeb uas siab -voltage circuit breakers yuav tsum ua tiav.
