I-Intelligent Universal Breaker CJW1 (ACB)
Ulwahlulo
- Ngokwendlela yokufakelwa: esisigxina nesokutsalwa
- Ngokweepali: iipali ezintathu, iipali ezine
- Ngokweendlela zokusebenza: injini kunye nesandla (ukugcinwa kunye nokulungiswa)
- Ngokwengxelo yokukhululwa: i-intelligent phezu kwesilawuli sangoku, ukukhululwa kwe-under-voltage instantaneous (okanye ukulibaziseka), kunye nokukhululwa kwe-shunt
- Amandla omlawuli we-over-current okrelekrele:
- udidi: Uhlobo lwe-H (oluqhelekileyo), uhlobo lwe-M (olukrelekrele oluqhelekileyo), uhlobo lwe-L (olunoqoqosho)
- inomsebenzi wokukhusela umda wexesha elide ngokulibaziseka kakhulu
- umsebenzi wokukhusela umhlaba onesigaba esinye
- umsebenzi wesalathiso: ukuseta isalathiso sangoku, isalathiso sangoku sesenzo, isalathiso ngasinye se-voltage yentambo (kufuneka sikhankanye njengoko uyalela).
- Umsebenzi we-alamu
- Umsebenzi wokuzixilonga
- Umsebenzi wovavanyo
Imeko Yendalo Yokusebenza Nokufakelwa
- Ubushushu obuphakathi: -5℃ ~ 40℃, kunye nobushushu obuphakathi kwiiyure ezingama-24 ngaphantsi kwe +35℃ (ngaphandle kwee-odolo ezikhethekileyo).
- Ukuphakama kwendawo yokufakela: ≤2000m.
- Ukufuma okunxulumeneyo: Akudluli kwi-50% kubushushu obuphezulu obuphakathi obuyi-+40℃. Xa ubushushu buphantsi, ukufuma okuphezulu kuya kuvunyelwa, kodwa ubushushu obuphakathi obuphantsi ngenyanga abudluli kwi-+25℃ ngexesha lenyanga emanzi kakhulu, kunye nomyinge ophezulu wenyanga ohambelanayo ongadluli kwi-90% kuloo nyanga, kwaye kuthathelwe ingqalelo amazolo kumphezulu wempahla, anokubonakala ngenxa yotshintsho lobushushu.
- Ukhuseleko longcoliseko: idigri ezi-3.
- Iindidi zokufakela: Ⅳ kwiisekethe eziphambili ze-breaker, iikhoyili zokukhululwa kwe-voltage ephantsi kunye nesekethe ephambili yee-transformers; Ⅲ kwezinye iisekethe ezincedisayo kunye nesekethe yokulawula.
- Iziqhekezi ezisetyenziswa kwiinqanawa nakwiindawo ezishushu ezinomswakama zinokusebenza ngokuqhelekileyo ngaphandle kwempembelelo yomoya ofumileyo, inkungu yetyuwa kunye nokungunda.
- Iziqhekeza ezisetyenziswa kwiinqanawa zinokusebenza ngokuthembekileyo phantsi kokungcangcazela okuqhelekileyo.
- I-breaker kufuneka ifakwe ngokwemiqathango ekwincwadi yemiyalelo yokusebenza. Kwi-breakers ezisetyenziswa rhoqo, i-gradient ethe nkqo ayidluli kwi-50, kwi-gradient esetyenziswa kwiinqanawa, i-gradient ethe nkqo ayidluli kwi-22.50.
- Isixhobo sokuqhekeza kufuneka sibekwe kwindawo apho kungekho nto iqhumayo kunye nothuli oluqhubayo kwaye kungekho gesi, enokonakalisa isinyithi okanye itshabalalise ubushushu.
- I-breaker kufuneka ifakwe kwindawo ye-switchboard kwaye ucango kufuneka lulungiswe, umgangatho wokhuseleko ufikelela kwi-lP40.
