Ii-MCCB zinamandla okuqhekeza aphezulu kwaye zinokusingatha imisinga yesekethe emfutshane ukuya kuthi ga kwishumi lee-kiloamperes (kA). Oku kuthetha ukuba zinokwahlula ngokukhawuleza iimpazamo kwaye zithintele umonakalo kwiiyunithi nezixhobo ezisezantsi. Amandla okuqhekeza aphezulu athetha ukuba ii-MCCB zinokusingatha imithwalo emikhulu, nto leyo evumela iinkqubo zombane ukuba zisebenze kumanqanaba aphezulu ombane.
2. Ulungiselelo lwenkqubo olulula
I-MCCB inezicwangciso zokuhamba ezihlengahlengiswayo ezivumela ukuba ilungiselelwe iimfuno ezithile zesicelo. Ezi zicwangciso ziqala kwiiyunithi zokuhamba ngemagnethi ezishushu ukuya kwiiyunithi zokuhamba nge-elektroniki kwaye zivumela i-MCCB ukuba iphendule kwiimeko ezahlukeneyo zomsinga ogqithisileyo ezifana ne-short circuit okanye i-overload. Besebenzisa i-MCCB, abasebenzisi banokulungisa izicwangciso ukuze banike inqanaba lokhuseleko elifunekayo kwaye baphucule ukusebenza kakuhle kwenkqubo yabo yombane.
3. Ukhuseleko lwemagnethi olushushu
Ii-MCCB zibonelela ngokudibanisa ukhuseleko lobushushu kunye nolwemagnethi. Izinto zohambo lokhuseleko lobushushu zisabela kwimithwalo engaphezulu, ngelixa izinto zokhuseleko lobushushu zisabela kwimijikelezo emifutshane. Indlela yohambo isabela kakhulu kwaye iya kusebenza ngokukhawuleza ngokusekelwe kwimeko yoxinzelelo lobushushu. Xa kufakwa i-MCCB, inkqubo yombane ixhamla kukhuseleko oluphambili kumonakalo wobushushu kunye nolwemagnethi.
4. Uyilo oluncinci
Inzuzo enkulu yeI-MCCBluyilo lwayo oluncinci. Zithatha indawo encinci kunee-circuit breakers ezindala kwaye zinokubotshelelwa okanye ziqhotyoshelwe kwi-DIN rail, nto leyo egcina indawo exabisekileyo yepaneli. Uyilo oluncinci lwenza i-MCCB ibe lula, inciphisa iindleko zokuthumela kwaye yenza kube lula ukuyiphatha nokuyifaka.
5. Ukuphuculwa kwamandla okubeka esweni nokunxibelelana
IiMCCB zanamhlanje zifaka itekhnoloji ye-microprocessor ephucukileyo, evumela ukuba zinxibelelane nezinye izixhobo kunye neenkqubo. IiMCCB zijonga kwaye zirekhode iiparameter ezifana nombane, i-voltage, amandla, kunye nokusetyenziswa kwamandla, zinceda abaqhubi kunye neenjineli ukulinganisa impilo iyonke yeenkqubo zombane. Ukongeza, amandla onxibelelwano avumela iiMCCB ukuba ziqhagamshelane neenkqubo zokubeka esweni, ukulawula kunye nokusebenza ngokuzenzekelayo, ukuphucula ulawulo kunye nokusebenza kwenkqubo yombane.
6. Iqinile kwaye ithembekile
Ii-MCCB zenzelwe ukumelana neendawo ezinzima kwaye zinokusebenza kumaqondo obushushu aqala kwi -25°C ukuya kwi +70°C. Zenziwe ngezinto ezisemgangathweni ophezulu ezimelana nokuguguleka kweekhemikhali kunye noomatshini, ezifana ne-polycarbonate, i-polyester kunye ne-ceramic. Ukongeza, ii-MCCB zihlala ixesha elide kakhulu, zihlala iminyaka eli-10 ukuya kwengama-20 kuxhomekeke ekusetyenzisweni nasekugcinweni kwazo.
7. Ukusetyenziswa kwemisebenzi emininzi
Ii-MCCB zinoluhlu olubanzi lwezicelo, ukusuka kwiinkqubo zombane ezisebenzisa umbane ophantsi ukuya kwiinkqubo zombane ezisebenzisa umbane onamandla aphezulu. Ziyinxalenye ebalulekileyo yokukhusela nokulawula iimoto, iijenereyitha, iitransformer kunye nezinye izixhobo zombane ezibalulekileyo. Ii-MCCB zikwangumgca wokuqala wokhuselo ekwakheni iinkqubo zombane, izitishi ezincinci, amashishini amakhulu kunye nezikhululo zamandla.
ukuququmbela
Ii-MCCB zizixhobo zokuqhekeza iisekethe ezinokuthenjwa, ezisebenzayo nezikhuselekileyo ezidlala indima ebalulekileyo kwiinkqubo zombane. Zibonelela ngokhuseleko olufunekayo kwizixhobo, kwiintambo kunye nabasebenzi kwiingozi kunye nomonakalo obangelwa yi-overcurrents kunye nee-short circuits. Useto oluphambili lwe-MCCB lokuhamba, ukhuseleko lwe-thermal magnetic, uyilo oluncinci, iimpawu zokubeka esweni, ukuqina kunye nokuguquguquka kwenza ukuba ibe lukhetho olufanelekileyo kuyo nayiphi na inkqubo yombane. Ukuqinisekisa ukusebenza kombane okuthembekileyo nokukhuselekileyo, tshintshela kwi-MCCBs kwaye ufumane iingenelo ezibonelela ngazo.
