Qonda intsingiselo kunye nendima ye-MCB kumbane (1)

Ingongoma yokuqala: Yintoni i-MCB

I-MCB, kwaziwa njengeiqhekeza lesekethe elincinci, yinto encinciumephuli wojikelezooko kudlala indima ebalulekileyo kwiinkqubo zombane. Ngokungafaniyo neefusi zemveli, ii-MCB zinokusetyenziswa kwakhona, zibonelela ngokhuseleko oluphuculweyo kwiimpazamo zombane ezibangelwa kukugqithisa kweesekethe okanye ii-short circuits. Ii-Miniature circuit breakers ziqinisekisa ukhuseleko kunye nokuthembeka kwezixhobo zombane ngokulawula ngesandla okanye ngokuzenzekelayo ukutshintsha iisekethe.

Umbono wesibini: Indlela esebenza ngayo i-MCB

Umgaqo wokusebenza we-MCB usekelwe kwindlela yokulibaziseka kwemagnethi yobushushu. Xa umbane uhamba nge-MCB, kuvela intsimi yemagnethi. Ukuba umbane ufikelela kwixabiso elimiselweyo, i-MCB iyakhubeka ngokuzenzekelayo ize inqumle isekethe. Ukongeza, izinto ezishushu kwi-MCB zibona utshintsho kubushushu. Ukuba ubushushu budlula ixabiso elimiselweyo, i-MCB iya kukhubeka kwakhona, ithintele isekethe ekubeni igqithise kakhulu.

Imbono Yesithathu: Iintlobo zeeMiniature Circuit Breakers

Ii-MCB ziyafumaneka kwiimodeli ezahlukeneyo ngokusekelwe kumandla azo alinganiselweyo, njenge-6A, 32A, 64A, njl. Zikwahlulwa ngokwenani leepali ezinazo, ukusuka kwi-unipolar, bipolar, ukuya kwi-three-pole configurations. Ukongeza, amandla okuqhekeza alinganiselweyo ee-miniature circuit breakers nawo ahlukile, kuquka i-4KA, 6KA, 8KA, njl.

Ingongoma yesine: Iingenelo ze-MCB

Ii-MCB zineengenelo ezininzi kunee-fuse zemveli. Okokuqala, ii-miniature circuit breakers zincinci, zilula, kwaye kulula ukuzifaka nokuzitshintsha. Uyilo lwazo oluncinci lwenza ukuba zilungele ukufakwa kombane kwanamhlanje. Okwesibini, ii-miniature circuit breakers zingasetyenziswa kwakhona amaxesha amaninzi, nto leyo eyenza ukuba zibe zezona zingabizi kakhulu kwaye zisebenziseke. Ngokungafaniyo nee-fuse, ekufuneka zitshintshwe emva kokusilela ngakunye, ii-MCBs zinokuphinda zisetyenziswe, oko konga ixesha kunye nezixhobo.

Ukongeza, i-MCB ibonelela ngokhuseleko oluphuculweyo kunye nokuthembeka. Banokuphazamisa isekethe ngesandla okanye ngokuzenzekelayo xa kuyimfuneko, bethintela umonakalo onokubakho okanye iimeko eziyingozi. Ngokuphendula ngokukhawuleza, i-MCB iqinisekisa ukuqhawuka kwesekethe ngokukhawuleza, ikhusela izixhobo zombane ekonakalisweni.
