Ukuqonda Ukubaluleka Kwe-Ama-MCCBEzinhlelweni Zikagesi
Emkhakheni wezinhlelo zikagesi, i-MCCB (Molded Case Circuit Breaker) idlala indima ebalulekile ekuqinisekiseni ukuphepha nokuthembeka kokufakwa konke. Le ngxenye ebalulekile yenzelwe ukuvikela amasekethe ekugcwaleni ngokweqile kanye namasekethe amafushane, ngaleyo ndlela ivimbele ukulimala okungenzeka emishinini kanye nokuqinisekisa ukuphepha kwabasebenzi.
Esinye sezici ezibalulekile ze-MCCB yikhono layo lokusingatha imisinga ephezulu. Lokhu kuyenza ifaneleke ezinhlobonhlobo zezicelo kusukela emishinini yezimboni kuya ekwakhiweni kwezentengiselwano. Ikhono lokusingatha imisinga ephezulu lisho ukuthi ama-MCCB angavikela ngempumelelo ekugcwaleni ngokweqile, okwenzeka lapho umusi ogeleza ngesekethe udlula umthamo wawo olinganiselwe. Kulesi simo, i-MCCB izokhubeka futhi iphazamise ukugeleza kwamandla kagesi, ngaleyo ndlela ivimbele noma yimuphi umonakalo wesekethe noma imishini exhunyiwe.
Esinye isici esibalulekile se-MCCB yikhono layo lokuvikela kuma-short circuits. I-short circuit yenzeka lapho uxhumano olungalindelekile luvela phakathi kwamaphuzu amabili ku-circuit, okubangela ukwanda okukhulu kwamandla kagesi. Lokhu kungabangela ukushisa ngokweqile futhi mhlawumbe ingozi yomlilo. Ama-MCCB aklanyelwe ukubona nokuphazamisa ngokushesha ukuhamba kukagesi lapho kwenzeka i-short circuit, ngaleyo ndlela kuvinjelwe noma yimuphi umonakalo noma ingozi engaba khona.
Ngaphezu komsebenzi wokuvikela, i-molded case circuit breaker nayo inenzuzo yokuba lula ukuyisetha kabusha ngemva kokukhubeka. Lokhu kusho ukuthi uma imbangela yokugcwala ngokweqile noma i-short circuit isixazululiwe, i-MCCB ingasethwa kabusha ukuze kubuyiselwe ukugeleza, kuncishiswe isikhathi sokungasebenzi futhi kuqinisekiswe ukuqhubeka kokusebenza.
Ngaphezu kwalokho, ama-MCCB amancane futhi kulula ukuwafaka, okwenza abe ukukhetha okusebenzayo kwezinhlelo zokusebenza ezahlukahlukene. Ubukhulu bawo obuncane busebenzisa kahle isikhala kuma-switchboard nama-switchboard, kuyilapho kulula ukuwafaka, okwenza abe ukukhetha okulula kwabakhi bezinto zikagesi kanye nabasebenzi bokulungisa.
Kufanele kuqashelwe ukuthi ama-case case circuit breaker akhiwe kufanele akhethwe futhi afakwe ngokwezidingo ezithile zesistimu kagesi. Izici ezifana nesilinganiso samanje, amandla okuphuka kanye nokuxhumana namanye amadivayisi okuvikela kufanele kucatshangelwe ngokucophelela ukuqinisekisa ukusebenza kahle nokuphepha.
Ngamafuphi, ama-MCCB adlala indima ebalulekile ekuvikeleni izinhlelo zikagesi ekugcwaleni ngokweqile kanye nama-short circuits. Amandla awo okusingatha amaza aphezulu, ukuvimbela ukungasebenzi kahle kanye nokuhlinzeka ngamakhono okusetha kabusha okulula kuyenza ibe yingxenye ebalulekile yokuqinisekisa ukuphepha nokuthembeka kokufakwa kukagesi. Ngokuqonda ukubaluleka kwama-MCCB nokukhetha i-MCCB efanele yesicelo esithile, izinhlelo zikagesi zingavikelwa futhi zigcinwe ngempumelelo ukuze zisebenze kahle.
