Izicelo

Ama-CJW1 series ahlakaniphile ama-universal circuit breakers angasetshenziswa i-fir elawula inethi yokusabalalisa i-voltage ephansi futhi ayigcine iphephile. Uma ifakwa kumaphaneli okusabalalisa i-voltage ephansi, isebenza njenge-master switch ukuze idlale indima yokuphepha evamile. Uhlobo lwayo lobuchwepheshe selufinyelele izinga elithuthukisiwe lomhlaba wonke lalolo hlobo lwemikhiqizo ngawo-1990. Ifanela isekethe ye-AC 50Hz, i-voltage elinganiselwe ingu-660V (690V) noma ngaphansi, i-current elinganiselwe ingu-400A-6300A.

Isilawuli esihlakaniphile esihlukahlukene sinikeza imisebenzi ehlukahlukene.

Ama-breaker ahambisana nezidingo zamazinga alandelayo, i-IEC 60947-2, i-GB14048.2-2001.

Silandela isimiso sokuphatha esithi “Ikhwalithi iyamangalisa, Inkampani iphakeme, Igama lihamba phambili”, futhi sizodala ngobuqotho futhi sabelane ngempumelelo nabo bonke amakhasimende e-CJW1-2000M-3P/4P Intelligent Universal Air Circuit Breaker Acb ene-IEC60947-2, Siyakwamukela ngobuqotho abathengi abavela kuyo yonke indawo emhlabeni ukuthi beze kithi, ngokubambisana kwethu okunezinhlangothi eziningi futhi sisebenzisana ngokubambisana ukwakha izimakethe ezintsha, senze ikusasa elingcono kakhulu elibikezelwayo.
Silandela isimiso sokuphatha esithi “Ikhwalithi iyamangalisa, Inkampani iphakeme, Igama liza kuqala”, futhi sizodala ngobuqotho futhi sabelane ngempumelelo nabo bonke amakhasimende.I-C&J Acb kanye ne-Air Circuit BreakerNgaphezu kwalokho, sisekelwa ochwepheshe abanolwazi oluphezulu nabanolwazi, abanobuchwepheshe obukhulu emkhakheni wabo. Laba ochwepheshe basebenza ngokubambisana ukuze banikeze amakhasimende ethu uhla lwemikhiqizo olusebenzayo.

Ukuhlukaniswa

Ngokusho kokufakwa: okulungisiwe nokudonswa ngaphandle
Ngokusho kwezinsika: izinsika ezintathu, izinsika ezine
Ngokwezindlela zokusebenza: injini kanye nesandla (ukulungiswa nokulungiswa)
Ngokusho kokukhishwa: isilawuli samanje esihlakaniphile, ukukhululwa okusheshayo (noma ukubambezeleka) okungaphansi kwe-voltage, kanye nokukhululwa kwe-shunt
Amandla esilawuli esihlakaniphile esisebenzisa amandla amaningi:
ukuhlukaniswa: Uhlobo lwe-H (olujwayelekile), uhlobo lwe-M (oluhlakaniphile olujwayelekile), uhlobo lwe-L (olunomnotho)
inomsebenzi wokuvikela umkhawulo wesikhathi esiphindaphindayo ukuze ibambezeleke kakhulu
umsebenzi wokuvikela owenziwe ngesigaba esisodwa
umsebenzi wokubonisa: ukusetha inkomba yamanje, inkomba yamanje yesenzo, inkomba ngayinye ye-voltage yentambo (kufanele isho njengoba u-oda).

Isimo Sendawo Yokusebenza Nokufakwa

Izinga lokushisa eliphakathi nendawo: -5℃ ~ 40℃, kanye nezinga lokushisa eliphakathi emahoreni angama-24 ngaphansi kuka-+35℃ (ngaphandle kwama-oda akhethekile).
Ukuphakama kwendawo yokufaka: ≤2000m.
Umswakama ohlobene: Akudluli ku-50% ekushiseni okuphezulu kwe-ambient okungu-+40℃. Uma izinga lokushisa liphansi, umswakama ophezulu uzovunyelwa, kodwa izinga lokushisa eliphansi kakhulu ngenyanga alidluli ku-+25℃ phakathi nenyanga emanzi kakhulu, kanye nenani eliphakeme kakhulu lenyanga elingadluli ku-90% kuleyo nyanga, kanye nokucabangela amazolo ebusweni bezimpahla, okuzovela ngenxa yokushintsha kwezinga lokushisa.
Ukuvikelwa kokungcola: 3 degree.
Izigaba zokufaka: Ⅳ zamasekethe amakhulu e-breaker, amakhoyili okukhululwa kwe-voltage ngaphansi kanye nesekethe eyinhloko yama-transformer; Ⅲ kwamanye amasekethe asizayo kanye nesekethe yokulawula.
Ama-breaker asetshenziswa emikhunjini nasezindaweni ezishisayo ezinomswakama angasebenza ngokujwayelekile ngaphandle kwethonya lomoya omanzi, inkungu kasawoti kanye nesikhunta.
Ama-breaker asetshenziswa emikhunjini angasebenza ngokuthembekile ngaphansi kokudlidliza okuvamile.
I-breaker kufanele ifakwe ngokwemigomo esencwadini yokusebenza. Kuma-breaker asetshenziswa njalo, i-gradient eqondile ayidluli ku-50, kuleyo esetshenziswa emikhunjini, i-gradient eqondile ayidluli ku-22.50.
I-breaker kufanele ibekwe endaweni lapho kungekho khona i-explosive medium kanye nothuli oluqhubayo futhi kungekho gesi, engagqwala insimbi noma ibhubhise i-insulation.
I-breaker kufanele ifakwe engxenyeni ye-switchboard futhi uhlaka lomnyango kufanele lulungiswe ngaphezu kwalokho, izinga lokuvikela lifinyelela ku-lP40.
