Izicelo

Ii-CJW1 series ezikrelekrele ze-universal circuit breakers zingasetyenziswa njenge-fir elawula i-low voltage distribution net kwaye ziyigcine ikhuselekile. Ukufakela kwiipaneli ze-low voltage distribution, isebenza njenge-master switch ukudlala indima yokhuseleko ngokubanzi. Uhlobo lobuchwephesha lufikelele kumgangatho ophezulu wamazwe ngamazwe waloo hlobo lweemveliso kwiminyaka yoo-1990. Ihambelana nesekethe ye-AC 50Hz, i-volage elinganisiweyo yi-660V (690V) okanye ngaphantsi, i-current elinganisiweyo yi-400A-6300A.

Isilawuli esikrelekrele esahlukeneyo sinika imisebenzi eyahlukeneyo.

Iziphuli-mlilo ziyahambelana neemfuno zemigangatho elandelayo, i-IEC 60947-2, i-GB14048.2-2001.

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.
