Yazisa:
Kubunjineli bombane,ii-breakers zesekethe ezibunjiweyo (Ii-MCCBs) zizinto eziphambili ekukhuseleni iinkqubo zombane kwi-overloads, iisekethe ezimfutshane kunye nezinye iindlela zokungaphumeleli.Ii-MCCBszisetyenziswa ngokuqhelekileyo kwizicelo ezahlukeneyo kwiindawo zokuhlala, zorhwebo kunye nezoshishino ukuze kuqinisekiswe ukusebenza ngokufanelekileyo nokukhuselekileyo kweenkqubo zombane.Kweli nqaku, siza kuphonononga usetyenziso, iimpawu, kunye nokuqwalaselwa kwee-MCCBs.
Ukusetyenziswa kweicala elibunjiweyo isaphuli sesekethe:
Ii-MCCBszisetyenziswa kwiinkqubo ezahlukeneyo ezibandakanya:
1. Izicelo Industrial: MCCBs ziqhele ukusetyenziswa kwimizi-mveliso ukubonelela ukhuseleko iinkqubo zombane nxamnye overloads, iisekethe ezimfutshane, kunye nezinye iintlobo iimpazamo.Ezi zicelo ziquka imveliso, i-oyile negesi, imigodi kunye nezinye iindawo zoshishino.
2. Izicelo zoRhwebo: I-molded case circuit breakers isetyenziswa kwizicelo zorhwebo, ezifana neendawo zokuthenga, iihotele, izakhiwo zeofisi, njl., Ukuqinisekisa ukusebenza ngokufanelekileyo nokukhuselekileyo kweenkqubo zombane.
3. Izicelo zokuhlala: I-molded case circuit breakers isetyenziswa kwizicelo zokuhlala ukuqinisekisa ukhuseleko lwabahlali bezindlu.Ifakwe kwiibhokisi zokusasaza ukukhusela iisekethe kwiimpazamo zombane.
Iimpawu zee-breakers zesekethe ezibunjiweyo:
1. Ireyithiwe yangoku: Ireyithi yokulinganisa yangoku ye-molded case circuit breakers yahlukile, ukusuka kwii-ampere ezimbalwa ukuya kwii-ampere ezingamawaka amaninzi.Olu phawu luyenza ikwazi ukusetyenziswa kwizicelo ezahlukeneyo.
2. Uphawu lokuhamba: I-molded case circuit breaker ine-tracking character, eqinisekisa ukuba ukuhamba kweesekethe kwimeko yombane ukukhusela umonakalo ongaphezulu.Uphawu lohambo lunokuba yi-thermal okanye magnetic.
3. Umthamo ophezulu wokuqhawula: I-molded case circuit breaker inomthamo ophezulu wokuqhawula kwaye inokumelana nephutha elikhulu langoku ngaphandle kokuphuka.Olu phawu luqinisekisa ukuba isiphaluka sikhuselekile kumonakalo.
4. Ukukhethwa: I-molded case circuit breaker inikezela ukukhetha kwisistim yombane, oko kukuthi, kuphela i-molded case circuit breaker kufuphi ne-fault trips, ngelixa ezinye iisekethe kwinkqubo yombane azichaphazeleki.
Izilumkiso zokukhetha ii-breakers zesekethe ezibunjiweyo:
1. Umlinganiselo wangoku: Xa ukhetha i-case circuit breaker, i-current rated current yenkqubo yombane kufuneka izimisele ukuqinisekisa ukuba i-molded case circuit breaker inokumelana nombane ngaphandle kokukhubeka.
2. Uhlobo lokusilela: Uhlobo lokusilela i-MCCB eyilelwe ukukhusela ngokuchasene nayo luqwalaselo olusisiseko xa ukhetha i-MCCB.Ngokomzekelo, ezinye ze-MCCB zenzelwe ukukhusela ukusilela kwe-thermal, ngelixa ezinye zenzelwe ukukhusela ukusilela kwemagnethi.
3. Ubushushu be-Ambient: Ubushushu be-ambient yokusingqongileyo apho i-mold case circuit breaker ikhoyo nayo iyimfuneko ebalulekileyo.I-MCCB inomlinganiselo wobushushu kwaye isenokungasebenzi kakuhle ukuba ubushushu be-ambient bugqithise umlinganiselo we-MCCB.
Isishwankathelo: I-MCCB licandelo elibalulekileyo kwinkqubo yombane njengoko ibonelela ngokhuseleko kwiimpazamo zombane.Inemisinga elinganisiweyo eyahlukileyo, iimpawu zokukhubeka kunye nomthamo wokuphuka, ngoko ifanelekile kwizicelo ezahlukeneyo.Xa ukhetha i-MCCB, ukulinganisa kwangoku, uhlobo lwempazamo, kunye nobushushu be-ambient kufuneka kuthathelwe ingqalelo ukuqinisekisa ukusebenza ngokufanelekileyo.
