Incwadana yemiyalelo ye-B6/RCBO (iodolwe)
1）ushwankathelo
I-B6 yintsalela yangoku esebenzayo ye-circuit breaker kunye ne-overcurrent yokukhusela kwikhaya kunye neenjongo ezifanayo (emva koku kuthiwa yi-circuit breaker), i-breaker circuit inokukhusela ukuvuza, ukugqithiswa kunye nemisebenzi yokukhusela isiphaluka esifutshane, ilungele i-AC 50Hz, i-voltage elinganisiweyo ye-230V, ilinganiswe. okwangoku kwimigca ye-40A yokukhusela.Xa umntu ebanjwe ngumbane okanye i-circuit leakage current idlula ixabiso elichaziweyo, i-breaker circuit inganqumla ngokuzenzekelayo umbane ngaphakathi kwe-0.1s ukuqinisekisa ukhuseleko lomntu kunye nokuthintela iingozi ezibangelwa ukuvuza kwangoku.Ingasetyenziselwa ukukhusela i-overload kunye nesiphaluka esifutshane somgca, kwaye ingasetyenziselwa ukuguqulwa okungaqhelekanga komgca phantsi kweemeko eziqhelekileyo.
Le mveliso ihambelana ne-GB16917.1,IEC61009
2）Uphawu
1. Imveliso iqukethe igobolondo, inkqubo yokusebenza, inkqubo yoqhagamshelwano, inkqubo yokucima i-arc, i-conductive system, inkqubo yokufumanisa i-residual yangoku, inkqubo ye-fault trip ye-fault, i-terminal yokuvavanya yangaphandle, i-buckle yokufakela, njl.
Imveliso yokukhusela i-overcurrent (i-overload and short circuit) ithatha ukukhutshwa kwe-hydraulic, kwaye iimpawu zokusebenza azichaphazeli ukushisa kwe-ambient.
3. Isixhobo sokukhululwa kwe-electromagnetic samkelwe ukukhusela ukuvuza okushiyekileyo kwemveliso.Iimpawu zizimeleyo kwi-voltage, kwaye i-residual current inokukhuselwa nje ukuba ifikelele kwixabiso lomgubasi.
4. Imveliso inemisebenzi emithathu yokukhusela isiphaluka esifutshane, ukukhuselwa kokugqithiswa kunye nokukhuselwa kokuvuza.N Ngaphandle kokugqithiswa kunye nokukhusela isiphaluka esifutshane.
3) Isaziso sovavanyo loMthengi:
1.Uvavanyo lwesi-2 lunokuvelisa i-residual current kwi-N kunye nomhlaba, onokuthi ukhubeke ukuba ufikelela kumda;
2.Uvavanyo lwesi-2 lu-equipotential ukuya ku-L, alukwazi ukuvelisa i-residual current, ayikwazi ukuhamba;
3. Iimpawu ze-overcurrent ziye zavavanywa kwi-factory enezixhobo ezizodwa kwaye zifanelekile;
4. Iimpawu zokukhusela iisekhethi ezimfutshane ziye zavavanywa kwifektri enezixhobo ezikhethekileyo, ezifanelekileyo;(Akukhuthazwa ukuba abasebenzisi bavavanye kwaye baqinisekise ngezixhobo ezingezizo ezobuchwephesha)
Iingcebiso zovavanyo
1. Ukukhuselwa kokuvuza: Umzi-mveliso usebenzise izixhobo ezikhethekileyo zokuvavanya nokuseta iimpawu zokukhusela ukuvuza ngokwemigangatho, ukuba umsebenzisi ufuna ukuqinisekisa, kuyacetyiswa ukuba uchukumise indawo ukusuka ekupheleni kokuphuma kwe-circuit breaker L (uchungechunge lwe i-milliammeter kwi-loop ukumisela ubungakanani bokuvuza kwangoku), i-breaker circuit kufuneka isebenze.
Qaphela: Ngezizathu zokhuseleko, unikezelo lwamandla ovavanyo kufuneka luxhotyiswe nge-30mA nangaphantsi komkhuseli wokuvuza, nxiba izihlangu zerabha zokugquma iiglavu, ukuthintela iingozi zokothuka kombane.
2. Ukukhuselwa komthwalo ogqithisiweyo: Umzi-mveliso weempawu zokukhusela umthwalo ogqithisiweyo uye wasebenzisa izixhobo ezikhethekileyo zokuvavanya nokuseta ngokomgangatho, ukuba umsebenzisi ufuna ukuqinisekisa, kuyacetyiswa ukuba uvavanye i-motor ebala umthwalo ngamaxesha angama-1.5 umlinganiselo olinganisiweyo wesekethe. i-breaker, kunye nexesha lokusebenza yi-50-90 imizuzwana;Amaxesha ama-2 kwixesha elilinganisiweyo langoku lokusebenza imizuzwana eyi-10-20.
3. Ukukhuselwa kwesiphaluka esifutshane: iimpawu zokukhusela isiphaluka esifutshane somzi-mveliso uye wasebenzisa izixhobo ezikhethekileyo zokuvavanya nokuseta ngokomgangatho, akukhuthazwa ukuba abasebenzisi basebenzise izixhobo ezingezizo ezobuchwephesha zokuqinisekisa, i-short circuit current iya kufikelela malunga ne-400A i-circuit breaker. ukuhamba, kuyingozi kakhulu, kubeka emngciphekweni ukhuseleko lomntu kunye nokhuseleko lwegridi yamandla.
