Incazelo emfushane:

Izinhlelo zokusebenza

Ama-CJW1 series ama-circuit breaker ahlakaniphile angasetshenziswa i-fir ukulawula inetha yokusabalalisa ama-voltage aphansi nokuyigcina iphephile.Ukufaka kumaphaneli okusabalalisa amandla kagesi aphansi, kusebenza njengeswishi eyinhloko ukudlala indima yokuphepha evamile.Imvelo yezobuchwepheshe isifinyelele izinga elithuthukile lomhlaba wonke lalolo hlobo lwemikhiqizo ngeminyaka yawo-1990.Ihambisana nesekhethi ye-AC 50Hz, i-volage elinganiselwe ingu-660V (690V) noma ngezansi, ikalwe ngo-400A-6300A yamanje.

Isilawuli esihlakaniphile esihlukahlukene sinikeza imisebenzi ehlukahlukene.

Ama-breaker ahambisana nezidingo zalawa mazinga alandelayo, IEC 60947-2, GB14048.2-2001.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Sigcizelela inqubekelaphambili futhi sethula izixazululo ezintsha emakethe unyaka ngamunye ze-China Supplier CJW1-450-1000-3p/4p Intelligent Universal Air Circuit Breaker Acb nge-IEC60947-2, Kanye nethagethi yaphakade “yokuthuthukiswa okuqhubekayo kwekhwalithi ephezulu, ukwaneliseka kwamakhasimende” , siye saqiniseka ukuthi imikhiqizo yethu ikhwalithi ephezulu izinzile futhi ithembekile futhi izixazululo zethu zithengiswa kakhulu ekhaya lakho naphesheya kwezilwandle.
Sigcizelela inqubekelaphambili futhi sethula izixazululo ezintsha emakethe unyaka ngamunyeI-China Acb kanye ne-Air Circuit Breaker, Uma unentshisekelo kunoma yisiphi isixazululo sethu noma ungathanda ukuxoxa ngomyalo wangokwezifiso, kufanele uzizwe ukhululekile ukuxhumana nathi.Besibheke ngabomvu ukwakha ubudlelwano bebhizinisi obuphumelelayo namakhasimende amasha emhlabeni jikelele esikhathini esizayo esiseduze.

Ukwahlukanisa

  • Ngokusho kokukhweza: kulungisiwe futhi kukhishwe
  • Ngokwezinti: izinti ezintathu, izinti ezine
  • Ngokusho kwezindlela zokusebenza: i-motor kanye ne-manual (ukugcinwa nokulungiswa)
  • Ngokuvumelana nokukhishwa: ihlakaniphile phezu kwesilawuli samanje, i-under-voltage ngokushesha (noma ukubambezeleka) ukukhululwa, nokukhululwa kwe-shunt
  • Amandla wesilawuli esihlakaniphile samanje:
  • ukuhlukaniswa: uhlobo H (oluvamile), uhlobo lwe-M (oluhlakaniphile oluvamile), uhlobo luka-L (lwezomnotho)
  • inomsebenzi wokulibazisa okuchichimayo ukuhlehlisa umkhawulo wesikhathi sokuvikela
  • umsebenzi wokuvikela wesigaba esisodwa somhlaba
  • umsebenzi wenkomba: ukusetha inkomba yamanje, inkomba yesenzo samanje, inkomba ngayinye ye-voltage yocingo (kufanele isho njengoba uyala).
  • Umsebenzi we-alamu
  • Umsebenzi wokuzihlola
  • Umsebenzi wokuhlola

Isimo Sendawo Sokusebenza Nokufakwa

  • Izinga lokushisa le-ambient: -5℃ ~ 40℃, kanye nezinga lokushisa elijwayelekile emahoreni angama-24 ngaphansi kuka +35℃ (ngaphandle kwama-oda akhethekile).
  • Ukuphakama kwendawo yokufaka: ≤2000m.
  • Umswakama ohlobene: Awedluli ama-50% ezingeni lokushisa eliphakeme kakhulu le-ambient elingu-+40℃.Uma izinga lokushisa liphansi, umswakama ophezulu uzovunyelwa, kodwa izinga lokushisa eliphansi kakhulu enyangeni elingadluli +25℃ phakathi nenyanga enomswakama kakhulu, kanye nesilinganiso esiphezulu sanyanga zonke se-numiaty esihlobene esingeqile ku-90% kuleyo nyanga, nokucabangela amazolo. endaweni yezimpahla, ezovela ngenxa yokushintsha kwezinga lokushisa.
  • Ukuvikelwa kokungcola: 3 degree.
  • Izigaba zokufaka: Ⅳ amasekhethi ayinhloko e-breaker, amakhoyili okukhipha amandla kagesi angaphansi kanye nesekhethi eyinhloko yama-transformer;Ⅲ kwamanye amasekhethi asizayo kanye nesekhethi yokulawula.
  • Izinqamuli ezisetshenziswa emikhunjini nasezindaweni ezishisayo ezishisayo zingasebenza ngokujwayelekile ngaphandle komthelela womoya oswakeme, inkungu kasawoti kanye nesikhutha.
  • Izinqamuli ezisetshenziswa emikhunjini zingasebenza ngokuthembekile ngaphansi kokudlidliza okuvamile.
  • I-breaker kufanele ifakwe ngokuya ngemibandela ebhalwe encwadini yokusebenza.Kumabreaker asetshenziswa okuvamile, i-gradient eqondile ayikho ngaphezu kuka-50, kulokho okusetshenziswa emikhunjini, i-gradient eqondile ayikho ngaphezu kuka-22.50.
  • I-breaker kufanele ibekwe endaweni lapho kungekho khona igesi eliqhumayo kanye ne-conductive dustand, engagqwalisa insimbi noma ibhidlize into efakwa ngaphakathi.
  • I-breaker kufanele ifakwe engxenyeni ye-switchboard futhi uzimele womnyango kufanele ulungiswe ngaphezu kwalokho, izinga lokuvikela lifika ku-lP40.
