Isihloko: Ukuqonda Ukubaluleka kweIiMiniature Circuit Breakers (iiMCB)uKhuseleko loMbane
yazisa:
Kwihlabathi lanamhlanje, umbane udlala indima ebalulekileyo kubomi bethu bemihla ngemihla. Nangona kunjalo, unokuba neengozi ezininzi ukuba awuphathwanga kakuhle. Ke ngoko, kubalulekile ukuthatha amanyathelo okhuseleko asebenzayo ukukhusela abantu kunye nezixhobo kwiingozi zombane. Enye yezinto ezibalulekileyo ukuqinisekisa ukhuseleko lombane yilei-miniature circuit breaker (MCB)Kule posi yebhlog, singena nzulu kwihlabathi leIi-MCB, ukubaluleka kwazo, kunye nendlela ezinegalelo ngayo kukhuseleko lombane.
1. Yintoni ii-miniature circuit breaker (MCB)?
A iqhekeza lesekethe elincinci, edla ngokubizwa ngokuba yi-I-MCB, sisixhobo sombane esenzelwe ukukhusela isekethe kunye nezixhobo zayo eziqhagamshelweyo kwi-overcurrent. I-overcurrent inokwenzeka ngenxa ye-short circuit okanye i-current eninzi kakhulu ehamba kwisekethe. I-MCB ijonga i-current ehamba kwisekethe kwaye iphazamisa okanye ikhuphe umbane ngokuzenzekelayo xa ibona i-overcurrent.
2. Kutheniiziphuli zesekethe ezincincikubalulekile kukhuseleko lombane?
2.1 Ukuthintela imililo yombane:
Imililo yombane ibangela inani elikhulu lemililo yehlabathi. Iisekethe zombane ezingasebenzi kakuhle okanye ezixineneyo zidla ngokubangela le mililo.I-MCBluluhlu lokuqala lokuzikhusela kwiziganeko ezinjalo. Xa umsinga ogqithisileyo ungena kwisekethe, i-miniature circuit breaker iyawa ngokukhawuleza, iqhawule isekethe ize inqumle umbane. Le mpendulo ikhawulezileyo ithintela iingcingo ekutshiseni kakhulu kwaye ibangele umlilo.
2.2 Ukukhuselwa kwezixhobo zombane:
Umbane ogqithisileyo unokonakalisa izixhobo zombane ezibuthathaka, nto leyo enokubangela ukulungiswa okanye ukutshintshwa okubiza kakhulu.Ii-MCBZikhusele ezi zixhobo ngokunqamula umbane xa kukho umbane ogqithisileyo. Ngokusebenza njengabalawuli beesekethe, zikhusela izixhobo kumonakalo obizayo obangelwa kukuguquguquka kwevolthi okanye ii-short circuits.
2.3 Ukhuseleko lomntu oluphuculweyo:
Ukuqhawuka kombane kuyingozi enkulu kubomi babantu. Ii-MCB zidlala indima ebalulekileyo ekunciphiseni umngcipheko weziganeko ezinjalo ngokuthintela ukuhamba kwamandla agqithisileyo kwiisekethe nakwizixhobo. Ukuqhawuka kwesekethe kunokuthintela iingozi ezinokubakho kwaye kukhusele abantu kwiingozi eziyingozi zombane.
3. Iimpawu kunye neenzuzo zee-miniature circuit breakers:
3.1 Uvavanyo lwangoku:
Ii-MCBziyafumaneka kwiireyithingi ezahlukeneyo zangoku kwaye zingasetyenziswa kwiindidi ezahlukeneyo zeesekethe kunye nezicelo. Nangona kunjalo, ureyithingi olufanelekileyo lwangoku kufuneka lukhethwe ngokwemithwalo yesekethe ukuqinisekisa ukhuseleko kunye nokusebenza okuphezulu.
3.2 Indlela esebenzayo yokukhubeka:
I-MCB inendlela yokujikeleza ngobushushu kunye nendlela yokujikeleza ngemagnethi. Indlela yokujikeleza ngobushushu ikhusela kwiimeko zokugqithiswa kwamandla, iimeko apho umsinga ogqithisileyo uhamba ixesha elide. Indlela yokujikeleza ngemagnethi ibona iisekethe ezimfutshane ezibandakanya imisinga ephezulu ixesha elifutshane.
3.3 Ukuseta kwakhona ngokukhawuleza nangokulula:
Emva kokuba i-MCB ikhubekile ngenxa yesiganeko okanye impazamo engaphezulu, ingasetyenziswa kwakhona ngokulula ngokubuyisela iswitshi yokutshintsha kwindawo ye-ON. Olu phawu lususa isidingo sokutshintsha iifusi ngesandla kwaye lubonelela ngendlela elula yokubuyisela amandla ngokukhawuleza.
4. Ukufakelwa nokugcinwa kwee-miniature circuit breakers:
4.1 Ufakelo lobuchwephesha:
Ukuqinisekisa ukusebenza ngokufanelekileyo kunye nokhuseleko olupheleleyo lombane we-I-MCB, ukufakelwa kwayo kufuneka kwenziwe rhoqo yingcali yombane eqeqeshiweyo. Banobuchule obufunekayo bokuvavanya ngokuchanekileyo iimfuno zomthwalo wesekethe kunye nokukhetha nokufaka i-MCB efanelekileyo.
4.2 Ukuhlolwa rhoqo kunye novavanyo:
Ukuhlolwa rhoqo kunye nokugcinwa kweiziphuli zesekethe ezincinciKubalulekile ekuchongeni iingxaki ezinokubakho, ukuqinisekisa ukuthembeka kwazo kunye nokugcina ukusebenza kwazo okuphezulu. Inkqubo yovavanyo kufuneka ilandelwe rhoqo ukuqinisekisa ukukhubeka kwe-MCB phantsi kweemeko ezigqithisileyo.
ukuququmbela:
Iziphuli zesekethe ezincinci (ii-MCB)ziyinxalenye ebalulekileyo yeenkqubo zombane ezibonelela ngokhuseleko olubalulekileyo kwiingozi zombane. Ngokubona nokucima umbane ngokukhawuleza xa kukho umbane ogqithisileyo, ii-miniature circuit breakers zithintela imililo yombane, zikhusela izixhobo, kwaye zikhusela abantu kwiingozi zombane eziyingozi. Ukulula kokusebenza, uphawu lokuseta kwakhona ngokukhawuleza, kunye nokufumaneka kwamanqanaba ahlukeneyo angoku kwenza ii-MCB zibe lukhetho oluhle kakhulu lokugcina ukhuseleko lombane kwiindawo ezahlukeneyo zokuhlala, zorhwebo, kunye nezoshishino. Kubalulekile ukubeka phambili ukufakwa, ukuhlolwa kunye nokugcinwa kweIi-MCBukuqinisekisa ukusebenza kwazo ngokugqibeleleyo nokudala imeko-bume yombane ekhuselekileyo kubo bonke abantu.
