CJW1-2000M-3P/4P Intelligent Universal Air Circuit Breaker Acb ene-IEC60947-2

Inkcazelo emfutshane:

Usetyenziso

I-CJW1 uthotho lwezaphuli zesekethe ezikrelekrele zendalo iphela zinokusetyenziswa ifir ukulawula umnatha wokuhambisa ombane ophantsi kunye nokuwugcina ukhuseleko.Ukufakela kwiiphaneli zokuhambisa umbane ophantsi, kusebenza njengokutshintsha okuphambili ukudlala indima yokhuseleko ngokubanzi.Indalo yobuchwephesha ifikelele kumgangatho ophezulu wehlabathi wolo hlobo lweemveliso ngo-1990s.Ihambelana nesekethe ye-AC 50Hz, i-volage elinganisiweyo yi-660V (690V) okanye ngaphantsi, ilinganiswe ngoku 400A-6300A.

Umlawuli okrelekrele ohlukeneyo ubonelela ngemisebenzi eyahlukeneyo.

Abaphuli bathobela iimfuno zale migangatho ilandelayo, IEC 60947-2, GB14048.2-2001.

Silandela imfundiso yolawulo "Umgangatho uyamangalisa, iNkampani iphezulu, igama lelokuqala", kwaye siyakwenza ngokunyanisekileyo kwaye sabelane ngempumelelo nabo bonke abathengi.I-C&J Acb kunye ne-Air Circuit Breaker, Ngaphaya koko, sixhaswa ngabasebenzi abanamava kunye nabanolwazi kakhulu, abanobuchule obukhulu kwisizinda sabo.Ezi ngcali zisebenza ngokubambisana ngokusondeleyo ukuze zinike abathengi bethu uluhlu olusebenzayo lweemveliso.

Ukuhlelwa

  • Ngokokunyuswa: kulungiswe kwaye kutsalwe ngaphandle
  • ngokwezibonda ezo: zantathu izibonda, nezibonda ezine
  • Ngokweendlela zokusebenza: imoto kunye nencwadana (ukugcinwa kunye nokulungiswa)
  • Ngokukhutshwa: ikrelekrele ngaphezulu komlawuli wangoku, ngaphantsi kwe-voltage kwangoko (okanye ukulibaziseka) ukukhululwa, kunye nokukhululwa kwe-shunt
  • Isakhono somlawuli okrelekrele wangoku:
  • Ukuhlelwa: Uhlobo lwe-H (oluqhelekileyo), uhlobo lwe-M (ingqondo eqhelekileyo), uhlobo lwe-L (uqoqosho)
  • unomsebenzi womthwalo ogqithisiweyo wokulibaziseka okude umva ukhuseleko lomda wexesha
  • umsebenzi wokhuselo wenqanaba elinye lomhlaba
  • umsebenzi wesalathiso: ukuseta isalathiso sangoku, isalathiso sangoku, isalathisi sombane wocingo ngalunye (kufuneka sikhankanye njengoko u-odola).
  • Umsebenzi we-alam
  • Umsebenzi wokuzihlola
  • Umsebenzi wovavanyo

Umqathango wokusiNgqongileyo wokuSebenza kunye noFakelo

  • Ubushushu be-Ambient: -5℃ ~ 40℃, kunye nobushushu obuphakathi kwiiyure ezingama-24 ngaphantsi +35℃ (ngaphandle kweeodolo ezikhethekileyo).
  • Ukuphakama kwendawo yofakelo: ≤2000m.
  • Ukufuma okuhambelanayo: Abukho ngaphezu kwe-50% kobona bushushu bobushushu bommandla obungu +40℃.Ngobushushu obuphantsi, ukufuma okuphezulu kuya kuvunyelwa, kodwa owona myinge usezantsi wobushushu eMontn ongagqithiyo kwi +25℃ ngeyona nyanga ifumileyo, kunye nowona myinge wenyanga uphezulu wokufuma ongekho ngaphezulu kwe-90% kuloo nyanga, kwaye unike ingqwalaselo kumazolo. kumphezulu wempahla, oya kuvela ngenxa yokutshintsha kobushushu.
  • Ukukhusela ukungcola: i-3 degree.
  • Iindidi zokufakela: Ⅳ kwiisekethe eziphambili ze-breaker, iikhoyili zokukhutshwa kwamandla ombane kunye neesekethe eziphambili zeenguqu;Ⅲ kwezinye iisekethe ezincedisayo kunye neesekethe zolawulo.
  • Izaphuli-mthetho ezisetyenziswa kwiinqanawa nakwiindawo ezifumileyo zetropikhi zinokusebenza ngokwesiqhelo ngaphandle kweempembelelo zomoya ofumayo, inkungu yetyuwa kunye nokungunda.
  • Izaphuli-mthetho ezisetyenziswa kwiinqanawa zinokusebenza ngokuthembekileyo phantsi kokungcangcazela okuqhelekileyo.
  • I-breaker kufuneka ifakwe ngokwemigqaliselo kwincwadana yokusebenza.Kwiziqhekeza ezisetyenziswayo eziqhelekileyo, i-gradient ethe nkqo ayikho ngaphezu kwe-50, kuba isetyenziselwa kwiinqanawa, i-gradient ethe nkqo ayikho ngaphezu kwe-22.50.
  • I-breaker kufuneka ibekwe kwindawo apho kungekho nasiphi na isiqhushumbisi kunye ne-conductive dustand, akukho gesi, enokuthi idle isinyithi okanye itshabalalise isigqubuthelo.
  • I-breaker kufuneka ifakwe kwi-compartment ye-switchboard kwaye umnyango womnyango kufuneka ulungiswe ukongeza, ibakala lokukhusela lifikelela kwi-lP40.
