Kuzo zonke iinkqubo zombane, ukhuseleko kunye nokukhuselwa kufuneka kuhlale kuphambili.Kulapho keI-MCCB or I-Case Molded Circuit Breakeringena. Ezi zixhobo eziyimfuneko ekukhuseleni izixhobo zombane, iisekethe kunye neengcingo ukusuka kwi-overcurrent kunye neesekethe ezimfutshane, ukuthintela iingozi zombane kunye nomonakalo wezixhobo.
Ii-MCCBsngabaphuli beesekethe banamhlanje ababonelela ngeenzuzo ezininzi ngaphezulu kweentlobo zemveli kunye nezakudalaabaphuli beesekethe.Kule bhlog, siza kuphonononga iingenelo zokusebenzisa i-MCCBs kwiinkqubo zombane kunye nendlela enokunceda ngayo ukuqinisekisa ukusebenza kombane okuthembekileyo nokukhuselekileyo.
1. Umthamo ophezulu wokuqhawula
Ii-MCCBs zinomthamo ophezulu wokuqhawula, olona xabiso luphezulu lwangoku abanokuphazamisa ngokukhuselekileyo.Ii-MCCBs zinomthamo ophezulu wokuqhawuka kwaye ziyakwazi ukusingatha imisinga ye-short-circuit currents ukuya kumashumi eekhilomperes (kA).Oku kuthetha ukuba banokukhawuleza bahlukanise iimpazamo kwaye bathintele umonakalo kwiiyunithi ezisezantsi kunye nezixhobo.Umthamo ophezulu wokuqhawula kwakhona kuthetha ukuba ii-MCCBs ziyakwazi ukusingatha imithwalo emikhulu, eyenza iinkqubo zombane zisebenze kumanqanaba aphezulu ombane.
2. Ulungiselelo olufanelekileyo lohambo
I-MCCB inesetingi zohambo ezilungelelanisiweyo ezivumela ukuba imiselwe iimfuno ezithile zesicelo.Ezi setingi zisusela kwiiyunithi zohambo lwemagnethi eshushu ukuya kwiiyunithi zohambo lwe-elektroniki kwaye zivumela i-MCCB ukuba iphendule kwiimeko ezahlukeneyo ezidlulayo ezifana nesekethe emfutshane okanye ukulayisha ngaphezulu.Ukusebenzisa i-MCCB, abasebenzisi banokulungisa izicwangciso zokubonelela ngenqanaba elifunekayo lokukhusela kunye nokwandisa ukusebenza kakuhle kwenkqubo yabo yombane.
3. Ukukhuselwa kwe-Thermal magnetic
Ii-MCCBs zibonelela ngokudityaniswa kokhuseleko lwe-thermal kunye nemagnethi.Izinto zohambo zokhuseleko lwe-thermal ziphendula kumthwalo ogqithisiweyo, ngelixa izinto zokukhusela kazibuthe ziphendula kwiisekethe ezimfutshane.Indlela yohambo isabela kakhulu kwaye iya kusebenza ngokukhawuleza ngokusekelwe kwimeko yokudlula.Xa i-MCCB ifakiwe, inkqubo yombane izuza kukhuseleko oluphezulu ngokuchasene nomonakalo we-thermal kunye nemagnethi.
4. Uyilo oluqinileyo
Inzuzo enkulu yeI-MCCBluyilo lwayo olubambeneyo.Bathatha indawo encinci kunezaphuli zesekethe zesitayile esidala kwaye zinokubotshwa okanye zikrwelwe kuloliwe weDIN, zigcina indawo yephaneli ebalulekileyo.Uyilo lwe-compact lwenza ukuba i-MCCB ibe khaphukhaphu, inciphise iindleko zokuthumela kunye nokwenza kube lula ukuyiphatha kunye nokuyifaka.
5. Ukuphuculwa kwamandla okubeka esweni nokunxibelelana
Ii-MCCB zanamhlanje zibandakanya itekhnoloji ye-microprocessor ephucukileyo, ibenza bakwazi ukunxibelelana nezinye izixhobo kunye neenkqubo.Ii-MCCBs zibeke iliso kwaye zirekhode iiparamitha ezinje ngoku, amandla ombane, amandla, kunye nokusetyenziswa kwamandla, ukunceda abaqhubi kunye neenjineli ukulinganisa impilo yonke yeenkqubo zombane.Ukongeza, izakhono zonxibelelwano zenza ukuba ii-MCCB zijongane nokubeka iliso, ulawulo kunye neenkqubo ezizenzekelayo, ukuphucula ulawulo lwenkqubo yombane kunye nokusebenza.
6. Iqinile kwaye ithembekile
Ii-MCCBs ziyilelwe ukuba zimelane nemekobume erhabaxa kwaye zinokusebenza kumaqondo obushushu ukusuka ku -25°C ukuya +70°C.Zenziwe ngezinto ezikumgangatho ophezulu ezichasene neekhemikhali kunye nokugqoka komatshini, njengepolycarbonate, i-polyester kunye ne-ceramic.Ukongeza, ii-MCCB ziphila ixesha elide kakhulu, zihlala iminyaka eyi-10 ukuya kwengama-20 ngokuxhomekeke ekusebenziseni nasekugcinweni kwazo.
7. Ukusetyenziswa kwezinto ezininzi
Ii-MCCBs zinoluhlu olubanzi lwezicelo, ukusuka kumbane ophantsi ukuya kwiinkqubo zombane zamandla aphezulu.Ziyinxalenye ebalulekileyo yokukhusela nokulawula iinjini, iijenereyitha, iziguquli kunye nezinye izixhobo zombane ezibalulekileyo.I-MCCBs nayo iyindlela yokuqala yokukhusela yokwakha iinkqubo zombane, izitishi, imboni enzima kunye nezityalo zamandla.
ukuququmbela
Ii-MCCBs zithembekile, zisebenza kwaye zikhuselekile ii-circuit breakers ezidlala indima ebalulekileyo kwiinkqubo zombane.Banikezela ngokhuseleko oluyimfuneko lwezixhobo, i-wiring kunye nabasebenzi kwiingozi kunye nomonakalo obangelwa yi-overcurrents kunye neesekethe ezimfutshane.Izicwangciso zohambo oluphezulu lwe-MCCB, ukhuseleko lwemagnethi ye-thermal, uyilo olubambeneyo, iifitsha zokubeka iliso, ukuqina kunye nokuguquguquka kwenza kube lukhetho olufanelekileyo kuyo nayiphi na inkqubo yombane.Ukuqinisekisa ukusebenza kombane okuthembekileyo nokukhuselekileyo, tshintshela kwi-MCCBs kwaye ufumane izibonelelo ezinikezelayo.
