Indawo yesicelo

• Ubushushu obuphakathi: -35~70°C
• Ukuphakama kwendawo yokufakela: ≤2500m.
• Ukufuma okulinganiselweyo: akudluli kwi-50% kubushushu obuphezulu obuphakathi kwe-+40°C Xa ubushushu buphantsi, ukufuma okuphezulu kuya kuvunyelwa. Umzekelo, xa ukufuma okulinganiselweyo kuyi-90% kubushushu obuphakathi be-20°C, kufuneka kuthathwe amanyathelo akhethekileyo ukuze kucocwe amazolo angaphezulu, abonakala ngenxa yokutshintsha kobushushu.
• Ukhuseleko longcoliseko: 3 grade.
• Iindidi zokufaka: llI kwiisekethe eziphambili ze-breakers.
• Intsimi yemagnethi yangaphandle kwindawo yokufakelwa kwe-circuit breaker akufuneki idlule amaxesha ama-5 kwintsimi ye-geomagnetic nakweyiphi na indlela.
• Iibreaker kufuneka zifakwe endaweni engenazo izinto eziqhumayo, uthuli oluqhubayo kwaye azinakonakalisa isinyithi kwaye zitshabalalise ubushushu.
• Lonke uthotho lwee-circuit breakers lungafakwa ngokuthe tye (ngokuthe tye) okanye ngokuthe nkqo (ngokuthe tye).

Imigangatho yesicelo

• Abaphuli-mthetho bathobela iimfuno zale migangatho ilandelayo:
• Imithetho ngokubanzi ye-IEC 60947-1 GB/T14048.1
• I-IEC 60947-2 GB/T14048.2 Iziphuli zesekethe

Ukusetyenziswa kunye nokugcinwa

• Musa ukusebenzisa i-circuit breaker ngezandla ezimanzi, kungenjalo kunokubakho iingozi zokutshayiswa ngumbane.
• Ii-circuit breakers akufuneki zisetyenziswe rhoqo, kungenjalo ziya kunciphisa ubomi benkonzo ye-circuit breaker.
• Qinisekisa ukuba uqhagamshelo lwesiphelo kunye nezikrufu zokulungisa zibotshelelwe kakuhle ngaphandle kokukhululeka.
• Jonga ukuba iingcingo zichanekile na.
• Sebenzisa i-megohmmeter ukulinganisa ukumelana nobushushu phakathi kwezigaba kunye naphakathi kwezigaba kunye nomhlaba.
• Qinisekisa ukuba i-circuit breaker phase partition ifakwe ngokufanelekileyo.
• Xa ufaka i-circuit breaker enokukhululwa kwe-undervoltage, i-undervoltagerelease kufuneka iqhagamshelwe kwi-voltage elinganisiweyo ngaphambi kokuba ivale i-circuit breaker, i-circuit breaker ikwimeko yokuvalwa.
• Faka ii-circuit breakers ezinee-assistant contacts kunye nee-alamu contacts. Xa uvala okanye uvula i-circuit breaker, i-assistant contact signal kufuneka iguqulwe ngendlela eqhelekileyo, cofa iqhosha le-emergency trip, kwaye i-alamu contact signal kufuneka iguqulwe ngendlela eqhelekileyo.
• Ukuba i-circuit breaker ixhotyiswe ngesixhobo sokusebenza sombane okanye esenziwe ngesandla, sebenzisa isixhobo sokusebenza ukuvula nokuvala amaxesha ama-3-5, Qinisekisa ukusebenza okuthembekileyo nokuqhelekileyo.
• Iimpawu ezahlukeneyo kunye nezixhobo ze-circuit breaker zisetwa ngumenzi wazo kwaye azinakulungiswa ngokungacwangciswanga ngexesha lokusetyenziswa. Phantsi kwemeko yokuba umsebenzisi uyayithobela imiqathango yokugcina kunye nokusetyenziswa, itywina le-circuit breaker kufuneka lihlale lingaphazanyiswa kwiinyanga ezingama-24 ukusukela kumhla wokuthunyelwa kumvelisi. Ukuba imveliso yonakele okanye ayinakusetyenziswa ngokuqhelekileyo ngenxa yeengxaki zomgangatho wokwenziwa, umenzi unoxanduva lokutshintsha nokulungisa simahla.
