Iindaba zeshishini

I-Miniature Circuit Breakers (MCBs) yenye yezona zinto zibaluleke kakhulu kwiinkqubo zokuhambisa umbane zanamhlanje. Ziyilelwe ukuba zikhuphe ngokuzenzekelayo iisekethe zombane xa kukho ukugqithiswa okanye iisekethe ezimfutshane, ukuthintela umonakalo wesixhobo, iingozi zomlilo, kunye neengozi zombane.

I-Air Circuit Breaker idlala indima ebalulekileyo ekukhuseleni iinkqubo zombane kwi-overloads, iisekethe ezimfutshane, kunye nokungaphumeleli kokusebenza. Ukusuka kwiifektri kunye nezakhiwo zorhwebo ukuya kwiinkqubo zamandla avuselelekayo kunye namaziko edatha, ezi ziqhekeza ziqinisekisa ukuhanjiswa kwamandla okuzinzile kunye nokuphucula ukhuseleko lokusebenza.

Ukukhetha i-breaker circuit efanelekileyo kufuna uvavanyo olubanzi lweeparamitha zesekethe, iimpawu zomthwalo, indawo yokufakela, kunye neemfuno zokukhusela. Iingqwalasela eziphambili ziqinisekisa ukuba i-voltage elinganisiweyo ihambelana ne-voltage yenkqubo, i-current rated current inkulu kunomthwalo wangoku kodwa ingaphantsi kwe-conductor current-carrying capacity, kunye nomthamo wokuqhawula (i-Icu) uphezulu kunoko kulindelwe i-short-circuit current.

Umgaqo-siseko wokusebenza wesaphuli sesekethe ujikeleza ingqiqo engundoqo yokubeka iliso, ukugweba, kunye nokuphunyezwa. Ngokusebenzisa indlela eyakhelweyo yokukhwela kunye nenkqubo yokucima i-arc, ifezekisa uxhulumaniso lwesekethe oluqhelekileyo kunye nolawulo lokuqhawula kunye nokuphazamiseka ngokukhawuleza kweesekethe eziphosakeleyo. Ngokukodwa, inokwahlulwa kwimodi yokusebenza eqhelekileyo kunye nemodi yokukhusela impazamo. Inkqubo yokucima i-arc yeyona ndlela ibalulekileyo encedisayo eqinisekisa ukuhamba okuthembekileyo.

Ii-Circuit breakers zizixhobo eziphambili kwiinkqubo zamandla, ezenza ulawulo lokutshintsha kweesekethe kunye nokukhusela impazamo ngokuzenzekelayo. Zisetyenziswa ngokubanzi kuzo zonke iimeko, ukusuka kumbane wendlu ukuya kwiigridi zamandla aphezulu. Imisebenzi yabo engundoqo igqithise / isiphaluka esifutshane / ukukhuselwa kokuvuza, ukhuseleko lwezixhobo, ukuzinza kokunikezelwa kwamandla, kunye nokukhusela umlilo kunye nombane.
