Kev Taw Qhia rau Universal Circuit Breaker Functions: Lub Circuit Court breaker nta peb - qhov loj me; cov kev sib txuas lus, instantaneous overcurrent mus txawv tebchaws chav tsev, thiab sab laug thiab sab daim hlau yog tag nrho mounted rau ib tug insulating board. Ib qho arc-kev tua hluav taws raug teeb tsa nyob rau sab saud, thaum lub tshuab ua haujlwm tuaj yeem tso ncaj qha rau pem hauv ntej lossis sab xis; nws suav nrog "Qhib" thiab "Closed" qhov taw qhia nrog rau phau ntawv mus ncig ua si khawm. Chav tsev shunt mus txawv tebchaws yog mounted nyob rau sab sauv -sab laug, thiab ib tug undervoltage mus txawv tebchaws unit-txuas mus rau ib nrab mus txawv tebchaws - ncej- nyob rau tom qab. Fast-saturating tam sim no transformers los yog tam sim no-rau-voltage converters yog haum rau hauv qab busbars. Lub sij hawm tsis muaj hluav taws xob- ncua sijhawm cov khoom siv, thermal relays, lossis semiconductor mus txawv tebchaws tej zaum yuav raug teeb tsa cais nyob rau hauv qis dua.
Lub DW15-2000, 3200, 4000, thiab 6300 series Circuit Court breakers kuj tseem siv peb -dimensional layout, featuring ib tug ncej qauv tsim ntawm lub hauv paus ncej, sab phaj, thiab crossbeams. Lub kaw lus tiv tauj rau txhua theem yog mounted ntawm lub hauv paus ncej, nrog lub arc -extinguishing chambers positioned saum toj no. Lub tshuab ua haujlwm yog nyob rau hauv pem hauv ntej- sab xis ntawm lub Circuit Court breaker thiab txuas mus rau kev sib cuag ntawm lub ntsiab ncej. Lub tshuab hluav taws xob ua haujlwm - koom nrog lub ntsiab mechanism ntawm lub square ncej- yog mounted nyob rau hauv qis seem ntawm lub Circuit Court breaker; nws ua haujlwm khaws cia lub zog rau lub breaker lossis ua haujlwm kaw ncaj qha. Thaum lub zog tau muab khaws cia, qhov kaw haujlwm yog ua los ntawm kev tso tawm electromagnet. Ib qho kev tiv thaiv rebound mechanism yog ntsia saum toj ntawm sab laug phaj los tiv thaiv Circuit Court breaker los ntawm bouncing thaum lub sij hawm qhib txheej txheem. Ntau yam overcurrent mus txawv tebchaws tau teeb tsa nyob rau hauv qis qis ntawm Circuit Court breaker kom tau raws li cov kev cai tshwj xeeb, thaum lub undervoltage mus txawv tebchaws unit, shunt trip unit, thiab hluav taws xob kev khiav hauj lwm tswj Cheebtsam nyob rau sab laug. Tshwj xeeb tshaj yog, lub undervoltage thiab shunt mus txawv tebchaws units yog txuas nrog ib tug amplification mechanism ntawm lub mus txawv tebchaws ncej, yog li txo lub tripping quab yuam yuav tsum tau rau lub Circuit Court breaker.
