I-CJMM1E 1000V 250A 3P yekhwalithi ephezulu ye-MCCB Moulded case circuit breaker Isithombe Esivelele

I-CJMM1E 1000V 250A 3P Electronic type MCCB Moulded case circuit breaker esezingeni eliphezulu

Incazelo emfushane:

·I-CJM1E series electronic plastic case circuit breaker (ebizwa ngokuthi i-circuit breaker), efanelekela i-AC 50H2 noma i-60Hz), i-insulation voltage yayo elinganisiwe ingu-1000V, i-voltage yokusebenza elinganisiwe ingu-690V nangaphansi, kanti i-operating current elinganisiwe ifinyelela ku-800A yokushintsha okungajwayelekile kuma-circuit. I-motor isetshenziselwa ukuqala okungajwayelekile. I-circuit breaker inomkhawulo wesikhathi ophambene nokulibaziseka okude, umkhawulo wesikhathi ophambene nokulibaziseka okufushane, umkhawulo wesikhathi oqondile olinganiselwe we-short circuit, imisebenzi yokuvikela i-short circuit esheshayo ne-undervoltage, ukuvikelwa kwamanje okusele (ongakukhetha), kanye nomsebenzi wokuvikela ukulahlekelwa kwesigaba (ongakukhetha). Ingavikela imigqa nemishini yamandla ekulimaleni. I-circuit breaker inezici zokuvikela eziphelele nezinembile, ezingathuthukisa ukuthembeka kokunikezwa kwamandla futhi zigweme ukucima kukagesi okungadingekile.

·Ama-circuit breaker ahlukaniswe izinhlobo ezimbili: Uhlobo lwe-M (uhlobo lokuphuka okuphezulu) kanye nohlobo lwe-H (uhlobo lokuphuka okuphezulu) ngokwesilinganiso sawo somkhawulo wokuphuka kwe-short circuit. Lesi sigaba sokuphuka sinezimpawu zobukhulu obuncane, amandla okuphuka aphezulu, i-arcing emfushane, kanye ne-anti-vibration.

·I-circuit breaker ingafakwa ngokuqondile (okungukuthi, ngokuqondile) noma ngokuqondile (okungukuthi, ngokuqondile).
·I-circuit breaker ayikwazi ukuhlehliswa, okungukuthi, yi-1, 3, kanye no-5 kuphela abavunyelwe ukuxhunywa ezintanjeni zikagesi kanti yi-2, 4, kanye no-6 abavunyelwe ukuxhunywa ezintanjeni zomthwalo.

Izimo Zokusebenza Nokufaka

·Ukuphakama: ≤2000m;
·Izinga lokushisa elizungezile: -5°C~+40°C;
·Ingakwazi ukumelana nethonya lomoya omanzi;
·Ingakwazi ukumelana nethonya lesifutho sikasawoti kanye nenkungu yamafutha;
·Isigaba sokufakwa kwesekethe eyinhloko ye-circuit breaker yi-III, kanti isigaba sokufakwa kwamanye amasekethe asizayo namasekethe okulawula yi-ll;
·Uma izinga lokushisa eliphezulu lingu-+40°C, umswakama womoya awudluli ku-50%. Umswakama ophezulu uvunyelwe uma kunomswakama ophansi. Kufanele kuthathwe izinyathelo ezikhethekile ukubhekana nokufiphala ngezikhathi ezithile ngenxa yokushintsha kwezinga lokushisa;
·Ukuthambekela okuphezulu kakhulu kungu-22.5°;
·Ku-medium engenangozi yokuqhuma, futhi lapho i-medium ingenawo amagesi nothuli oluhambisa umoya olungagqwala insimbi futhi lubhubhise ukufudumala;
·Endaweni lapho kungekho mvula noma iqhwa.

Vikela

·Ukulungiswa kwe-Ir1 yamanje yesenzo sokubambezeleka isikhathi eside kungalungiswa kusuka kumaphuzu angu-4 kuya kwangu-10 ngokuya ngemisinga ehlukene elinganisiwe ye-circuit breaker;
·Isikhathi sokulibaziseka eside t1 singalungiswa ngamaphuzu ama-4;
·I-Ir2 yamanje yesenzo sokulibaziseka esifushane ingalungiswa ngamaphuzu ayi-10;
Ukulungiswa kwesenzo sokulibaziseka okufushane kwe-t2, ukulungiswa kwamaphuzu angu-4 kuyatholakala;
I-Ir3 yamanje yokusebenza esheshayo ye-short-circuit ingalungiswa ngamaphuzu angu-9 noma angu-10;
I-Ir0 yamanje yesenzo sangaphambi kwe-alamu ingalungiswa ngamaphuzu ayi-7;
Itheminali yokuhlola, esetshenziselwa ukuthola inani lamanje lokusetha le-tripper kagesi;
Imiyalelo yokusebenza yokukhishwa kwe-elekthronikhi;
Imiyalelo yangaphambi kwe-alamu;
Isibonakaliso sokulayisha ngokweqile;
Inkinobho yohambo.
