Iziphuli zesekethe ezincinci: isisombululo esincinci sokhuseleko lombane

Kwicandelo lokhuseleko lombane,ii-miniature circuit breakers (ii-MCB)ziye zaba sisisombululo esincinci nesisebenzayo sokukhusela iisekethe kwiingxaki ezinkulu kunye neesekethe ezimfutshane. Ezi zixhobo zithembeke kakhulu zithandwa ngenxa yokukwazi kwazo ukuqinisekisa ukuhamba kwamandla okuthe tye, okungaphazanyiswayo ngelixa ziphucula amanyathelo okhuseleko ngokubanzi. Kweli nqaku, siza kujonga ngokusondeleyo iimpawu kunye neenzuzo zee-miniature circuit breakers.

I-miniature circuit breaker sisixhobo se-electromechanical esenzelwe ukusebenza ngokuzenzekelayo njengeswitshi xa kukho umbane omninzi okanye i-short circuit. Sisebenza njengenethi yokhuseleko, sithintela umonakalo kwizixhobo zombane okanye kwiingozi zomlilo ngokubona umbane ogqithisileyo kwaye siphazamise i-circuit ngokukhawuleza.

Enye yezona nzuzo ziphambili zee-miniature circuit breakers bubukhulu bazo obuncinci. Zenzelwe ukuthatha indawo encinci kwi-switchboard okanye kwi-switchboard. Ngokungafaniyo nezinye ezinkulu ezifana nee-molded case circuit breakers okanye ii-fuses, ii-MCB zinokufakwa ngokufanelekileyo kwiindawo ezixineneyo, nto leyo ezenza zibe zilungele ukusetyenziswa kwiindawo zokuhlala, ezorhwebo nakwimizi-mveliso. Olu phawu luba lubaluleke kakhulu kwizakhiwo zanamhlanje nakwizindlu apho ukulungiswa kwendawo kubaluleke khona.

Enye into ebalulekileyo kwii-miniature circuit breakers kukuba lula kwazo ukusebenza kunye nendlela yokuseta kwakhona. Ukuba kwenzeka i-overload okanye i-short circuit breaker, i-miniature circuit breaker iyakhubeka ngokuzenzekelayo kwaye ikhuphe i-circuit, ikhusela izixhobo zombane. Nje ukuba impazamo isusiwe, i-miniature circuit breaker inokuphinda isetyenziswe ngokulula ukuze ibuyisele umbane ngaphandle kokutshintshwa okanye iindleko ezongezelelweyo. Olu phawu lulula ukuyisebenzisa lunciphisa ixesha lokungasebenzi kwaye lubonelela ngokulula ngakumbi kubanini bezindlu kunye neengcali.

Ukongeza, ii-miniature circuit breakers ziyafumaneka kwiindidi ezahlukeneyo zangoku, ukusuka kwii-amps ezimbalwa ukuya kwii-amps ezingamakhulu, nto leyo evumela ukuba zikhethwe ngokuchanekileyo ngokweemfuno zenkqubo ethile yombane. Oku kuguquguquka kwenza iinjineli zombane kunye nabafaki bakwazi ukuhlangabezana neemfuno ezahlukeneyo zesicelo, ukuqinisekisa ukhuseleko olufanelekileyo ngamaxesha onke. I-MCB ikwabonelela ngezicwangciso zokuhamba ezihlengahlengiswayo, ivumela ukuba umgangatho wokhuseleko wenziwe ngokwezifiso ukuhlangabezana neemfuno ezizodwa zeesekethe ezahlukeneyo.

Ukuthembeka yinto ebalulekileyo kukhuseleko lombane, kwaye ii-miniature circuit breakers zibalaseleyo kule ndawo. Ngokwakhiwa kwayo okuhlala ixesha elide kunye nezixhobo ezikumgangatho ophezulu, i-MCB inika ukhuseleko oluthembekileyo ixesha elide. Zenzelwe ukumelana nee-short circuits kunye ne-high fault currents ngaphandle kokuguguleka okukhulu. Le nto yokuthembeka iqinisekisa ukusebenza okuhlala ixesha elide kwaye inciphisa iindleko zokulungisa.

Ukongeza ekuqinisekiseni ukhuseleko lombane, ii-miniature circuit breakers zikwanceda ekuphuculeni ukusebenza kakuhle kwamandla. Ii-MCB ziyakwazi ukubona nokuphazamisa umbane ogqithisileyo, zithintele ukusetyenziswa kwamandla okungeyomfuneko kwaye zinciphise umngcipheko wemililo yombane. Ziyinxalenye ebalulekileyo yokusebenza kakuhle kwenkqubo yombane, nto leyo ezenza zibe yimpahla ebalulekileyo kwiindawo ezahlukeneyo.

Konke kwinto enye,iziphuli zesekethe ezincinciziye zaba yinxalenye ebalulekileyo yeenkqubo zombane kwihlabathi liphela. Ubungakanani bayo obuncinci, ukulula kokusebenza, ukukhetha ngokuchanekileyo, ukuthembeka kunye nokusebenza kakuhle kwamandla kwenza ukuba ibe lolona khetho luphambili lokukhusela iisekethe. Ukusebenzisa i-miniature circuit breaker akuqinisekisi nje kuphela ukunikezelwa kwamandla okungaphazanyiswa, kodwa kunciphisa nomngcipheko wokutshayiswa ngumbane, kukunika uxolo lwengqondo. Njengoko isidingo sokhuseleko lombane siqhubeka sikhula, ii-miniature circuit breakers ziyaqhubeka nokudlala indima ebalulekileyo kushishino, ziguqula indlela esikhusela ngayo iinkqubo zombane.
