• I-CJM6HU series molded AC circuit breaker ingaphuka ifike ku-50kA ngaphansi kwe-AC800V voltage, engenza ukuvikelwa kwe-short circuit kube ngokuthembekile.
• Ama-CJM6Z series molded case circuit breakers ane-320A, 400A, 630A, 800A, ama-current cases angu-4 avela ku-63A-800A, ane-voltage yokusebenza elinganiselwa ku-DC1500V.
• I-CJM6Z series molded case circuit breaker ingaphuka ifike ku-20kA ngaphansi kwe-DC 1500V voltage, engakwazi ukuvikela i-short circuit ngokuthembekile.

Indawo yokusetshenziswa

• Izinga lokushisa elizungezile: -35~70°C
• Ukuphakama kwendawo yokufaka: ≤2500m.
• Umswakama ohlobene: ongadluli ku-50% ekushiseni okuphezulu kwe-ambient okungu-+40°C Uma izinga lokushisa liphansi, umswakama ophezulu uzovunyelwa. Isibonelo, uma umswakama ohlobene ungama-90% ekushiseni kwe-ambient okungu-20°C, kufanele kuthathwe izinyathelo ezikhethekile zokuxazulula amazolo ebusweni, okuzovela ngenxa yokushintsha kwezinga lokushisa.
• Ukuvikelwa kokungcola: ibanga lesi-3.
• Izigaba zokufaka: i-llI yamasekethe amakhulu ama-breaker.
• Insimu yamagnetic yangaphandle endaweni yokufaka i-circuit breaker akufanele idlule izikhathi ezi-5 kunensimu yamagnetic kunoma iyiphi indlela.
• Ama-breaker kufanele afakwe endaweni engenawo ugesi oqhumayo, uthuli oluqhubayo futhi awakwazi ukugqwala insimbi futhi abhubhise ukufudumala.
• Lonke uchungechunge lwama-circuit breaker lungafakwa ngokuvundlile (ngokuphambeneyo) noma ngokuvundlile (ngokuqondile).

Izindinganiso zohlelo lokusebenza

• Ama-breaker ahambisana nezidingo zalezi zindinganiso ezilandelayo:
• Imithetho ejwayelekile ye-IEC 60947-1 GB/T14048.1
• I-IEC 60947-2 GB/T14048.2 Ama-circuit breaker

Ukusetshenziswa nokugcinwa

• Ungayisebenzisi i-circuit breaker ngezandla ezimanzi, ngaphandle kwalokho kungase kube nezingozi zokushaqeka ngogesi.
• Ama-circuit breaker akufanele asetshenziswe njalo, ngaphandle kwalokho kuzofinyeza impilo yesevisi ye-circuit breaker.
• Qinisekisa ukuthi ukuxhumeka kwe-terminal kanye nezikulufo zokulungisa kuboshwe kahle ngaphandle kokukhululeka.
• Hlola ukuthi izintambo zilungile yini.
• Sebenzisa i-megohmmeter ukukala ukumelana kokushisa phakathi kwezigaba naphakathi kwezigaba kanye nomhlabathi.
• Qinisekisa ukuthi i-circuit breaker phase partition ifakwe kahle.
• Uma ufaka i-circuit breaker enokukhululwa kwe-undervoltage, i-undervoltagerelease kufanele ixhunywe ku-voltage elinganisiwe ngaphambi kokuvala i-circuit breaker, i-circuit breaker isesimweni sokuvalwa.
• Faka ama-circuit breaker anokuxhumana okusizayo kanye nokuxhumana kwe-alamu. Uma uvala noma uvula i-circuit breaker, isignali yokuxhumana okusizayo kumele iguqulwe ngokujwayelekile, cindezela inkinobho yohambo oluphuthumayo, bese isignali yokuxhumana kwe-alamu kumele iguqulwe ngokujwayelekile.
• Uma i-circuit breaker ifakwe indlela yokusebenza kagesi noma ngesandla, sebenzisa indlela yokusebenza ukuvula nokuvala izikhathi ezingu-3-5, Qinisekisa ukusebenza okuthembekile nokujwayelekile.
• Izici ezahlukene kanye nezesekeli ze-circuit breaker zisethwa ngumkhiqizi wazo futhi azikwazi ukulungiswa ngokungahleliwe ngesikhathi sokusetshenziswa. Ngaphansi kwesimo sokuthi umsebenzisi uhambisana nemibandela yokugcina nokusebenzisa, uphawu lwe-circuit breaker kufanele luhlale luphelele zingakapheli izinyanga ezingama-24 kusukela ngosuku lokuthunyelwa kumkhiqizi. Uma umkhiqizo wonakele noma ungasetshenziswa ngokujwayelekile ngenxa yezinkinga zekhwalithi yokukhiqiza, umenzi unesibopho sokushintsha nokulungisa mahhala.

Ukusebenza okuyinhloko kobuchwepheshe
