Indima ye-MCB

Isixhobo sokwaphula iisekethe esincinci (I-MCB) zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko kunye nokukhuselwa kwezixhobo zasekhaya kunye nezixhobo ze-elektroniki. Ii-Miniature circuit breakers zisetyenziswa kakhulu ukuthintela ukugqithiswa kakhulu, ii-short circuit kunye nokuvuza, ngaloo ndlela zikhusela izixhobo ekonakaleni kwaye zinciphise ukusetyenziswa kwamandla. Ubungakanani bazo obuncinci, ukulula kokufakwa, ukuthembeka okuphezulu kunye nokusebenza kakuhle kweendleko kuzenza zibe yinxalenye ebalulekileyo kwiinkqubo zombane.

Omnye wemisebenzi ephambili ye-MCBs kukubonelela ngokhuseleko lwesekethe emfutshane. Xa kwenzeka impazamo yesekethe emfutshane kwaye umsinga kumgca mkhulu kakhulu, i-miniature circuit breaker isebenzisa amandla e-electromagnetic aveliswa yi-electromagnetic coil ukuqhuba i-iron core, ityhale intonga yokutyhala ukuze ivuleke, kwaye ikhuphe isekethe ngexesha elifutshane. Ngaphantsi kwemizuzwana eyi-0.1. Le mpendulo ikhawulezayo kwiimpazamo zesekethe emfutshane inceda ukuthintela umonakalo onokubakho kwizixhobo kwaye iqinisekisa ukhuseleko lweenkqubo zombane.

Ukongeza kukhuseleko lwesekethe emfutshane, ii-MCB zenzelwe ukubonelela ngokhuseleko lokugqithisa. Xa umbane kumgca udlula umbane olinganiselweyo kodwa usengaphantsi kunexabiso lombane wesekethe emfutshane elibekiweyo, nto leyo ebangela impazamo yokugqithisa, i-thermal bimetallic element kwi-miniature circuit breaker iyagoba kwaye imelane nokutshixa, ngaloo ndlela iphula umbane. Ixesha lokwaphuka liyatshintsha ngokobukhulu bombane ogqithisileyo, kwaye ubungakanani bamandla ahlukeneyo buhambelana namanqanaba ahlukeneyo okulibaziseka. Olu phawu lunceda ukuthintela izixhobo ekutshiseni kakhulu kunye nomonakalo onokubakho obangelwa kukugqithisa ixesha elide.

Xa kujongwa amandla okuqhekeza ii-MCB, kubalulekile ukuqaphela ukuba zenzelwe ukwamkela uluhlu lweendlela zokuqhekeza iisekethe ezimfutshane. Umthamo wokuqhekeza iisekethe ezimfutshane (Icn) olinganiselweyo wezixhobo zokuqhekeza iisekethe ezincinci eziqhelekileyo udla ngokuba yi-6A ukuya kwi-63A, apho amandla okuqhekeza iisekethe ezincinci ze-6A ukuya kwi-40A yi-6KA, kwaye amandla okuqhekeza iisekethe ezincinci ze-50A ukuya kwi-63A yi-4.5KA. Ukongeza, amandla okuqhekeza iisekethe ezimfutshane (Ics) asebenza nawo achazwe njenge-6KA kwizixhobo zokuqhekeza iisekethe ezincinci ze-6A ukuya kwi-40A kunye ne-4.5KA kwizixhobo zokuqhekeza iisekethe ezincinci ze-50A ukuya kwi-63A. Ezi zakhono zokuqhekeza ziqinisekisa ukuba izixhobo zokuqhekeza iisekethe ezincinci zinokuphazamisa iisekethe ngokukhuselekileyo phantsi kweemeko ezahlukeneyo zezixhobo zokuqhekeza ezimfutshane, zongeza umaleko wokhuseleko kwiinkqubo zombane.

Ukuguquguquka nokusebenza kakuhle kwe-MCB kuyenza ibe yinxalenye ebalulekileyo yokukhusela izixhobo zasekhaya kunye nezixhobo ze-elektroniki. Amandla okukhusela ukulayisha kakhulu, ukujikeleza okufutshane kunye nokuvuza awakhuseli nje kuphela izixhobo kodwa anceda ekunciphiseni ukusetyenziswa kwamandla. Ii-MCB zincinci, kulula ukuzifaka, zithembekile kakhulu kwaye ziyafikeleleka, zibonelela ngesisombululo esingabizi kakhulu sokuqinisekisa ukhuseleko kunye nokukhuselwa kweenkqubo zombane. Nokuba sisicelo sendawo yokuhlala, sorhwebo okanye semizi-mveliso, ii-miniature circuit breakers zibalulekile ekugcineni ingqibelelo kunye nokhuseleko lokufakelwa kombane.

Iqela leMutai liqokelele amava angaphezu kweminyaka elishumi okuvelisa nokuthengisa kwi-iziphuli zesekethe, izixhobo zoqhagamshelwano, iiswitshi zokudlulisela ngokuzenzekelayo zamandla amabini (I-ATS) kunye neenkalo ezinxulumene noko. Silangazelela ithuba lokusebenza nani.
