Intshayelelo kuIi-MCCBs

Ii-MCCBs zithiywe ngegama loyilo lwazo olulodwa, apho amacandelo e-breaker circuit afakwe kwi-mold, i-insulated yezindlu zeplastiki. Le ndlu ibonelela ngokhuseleko oluphezulu kwiingozi zokusingqongileyo njengothuli, ukufuma, kunye nokunxibelelana ngokomzimba ngengozi, kubenza ukuba bahlale ixesha elide kwaye bethembekile kwiisetingi ezahlukeneyo zokusebenza. Ezi zaphuli ziza ngobukhulu obahlukeneyo, zivumela uluhlu olubanzi lwangoku kunye nokulinganisa kwamandla ombane ukuze zilungele izicelo ezahlukeneyo.

Ii-MCCBs zigqamile ngenxa yazouyilo oludibeneyo, amandla okuphazamisa aphezulu, kwayeukuthembeka. Ezi mpawu zibenza zibe yimfuneko ekusetyenzisweni kwiimeko apho ukusebenza okufanayo kunye nokukhuselekileyo kweesekethe zombane kubalulekile, ukusuka kwiindawo zokuhlala ezincinci ukuya kuthungelwano lwemizi-mveliso emikhulu.

ImiSebenzi ePhambili yee-MCCBs

I-Molded Case Circuit Breakers isebenza kwiindima ezininzi ezibalulekileyo ekuqinisekiseni ukhuseleko kunye nokusebenza kweesekethe zombane:

 

1. uKhuseleko lomthwalo ogqithisileyo

Ii-MCCBs zixhotyiswe ngokhuseleko lwe-thermal oluphendula kwiimeko ezizinzileyo zokugcwala. Xa ukulayisha ngaphezulu kwenzeka, ukonyuka kwangoku kubangela ukuba i-thermal element ishushu. Njengoko iqondo lobushushu linyuka, ekugqibeleni libangela indlela yohambo, ukwaphula isiphaluka nokuthintela umonakalo ongakumbi. Oku kuphazamiseka okuzenzekelayo kukhusela izixhobo zombane kunye neengcingo ekutshiseni, ukunciphisa umngcipheko womlilo.

 

2. Ukukhuselwa kweSekethe emfutshane

Kwimeko yesiphaluka esifutshane, apho ukuhamba kwangoku kudlula umthwalo kwaye kudala indlela ethe ngqo phakathi komthombo wamandla kunye nomhlaba, ii-MCCBs zisebenzisa i-magnetic trip mechanism. Lo matshini usebenza ngoko nangoko, ngokwesiqhelo kwi-milliseconds, ukuphazamisa ukuhamba kwangoku. Ukusabela ngokukhawuleza kwe-MCCB kuthintela umonakalo omkhulu kwizixhobo kunye neengcingo, ngelixa kunciphisa ingozi yomlilo wombane.

 

3. Ukukhuselwa kweFault Fault

Iziphene ezisemhlabeni zenzeka xa umsinga uphuncuka kwindlela ebewuyilindele kwaye ufumane indlela eya emhlabeni, enokubangela iingozi zothuso okanye umonakalo wesixhobo. Ii-MCCBs ziyakwazi ukubona iimpazamo ezisemhlabeni kwaye zihambe kwangoko ziye kubeka bucala isiphene kwaye zikhusele izixhobo kunye nabasebenzi ekwenzakaleni.

 

4. Ulawulo Lwezandla loLondolozo

Ii-MCCBs nazo ziyilelwe ukusebenza ngesandla, ezivumela abasebenzisi ukubavula ngesandla okanye uvaleumaphuli. Olu phawu lubalulekile ekubekeni bucala iisekethe zombane ngexesha lokugcinwa, uvavanyo, okanye ukuphuculwa kwenkqubo, ukuqinisekisa ukhuseleko lwabasebenzi bolondolozo ngokuthintela ukuphinda unikwe amandla ngengozi.

 

Ukusebenza kwee-MCCBs

Ukusebenza kwe-MCCB kujikeleza kwiindlela ezimbini eziphambili zohambo:ukhuseleko thermalkwayeukhuseleko lwemagnethi.

 

Ukukhuselwa kweThermal

Ukukhuselwa kwe-thermal kunikezelwa ngumgca we-bimetallic ngaphakathi kwe-breaker. Ngethuba lokusebenza okuqhelekileyo, umgca we-bimetallic uhlala upholile kwaye i-breaker ihlala ivaliwe, ivumela ukuba i-current ihambe. Xa ukugqithisa kwenzeka, ukwanda kwangoku, kubangela ukuba umgca we-bimetallic ushushu kwaye ugobe. Oku kugoba ekugqibeleni kukhubaza isaphuli, kunqumle unikezelo lombane. Ukukhuselwa kwe-thermal kulungele ukukhusela ngokugqithiswa kwezinto ezikhulayo ngokuhamba kwexesha, ukuqinisekisa ukuba i-breaker iphendula ngokufanelekileyo ngaphandle kokuphazamiseka okungadingekile.

 

Ukhuseleko lweMagnetic

Ukukhuselwa kwamagnetic, ngakolunye uhlangothi, yenzelwe ukuphendula ngokukhawuleza kwiisekethe ezimfutshane. Ikhoyili engaphakathi kwi-breaker idala i-magnetic field xa i-short circuit isenzeka, ibangela ukuba i-plunger ihambe i-breaker ngokukhawuleza. Le mpendulo ngokukhawuleza ibalulekile ekunciphiseni umonakalo obangelwa yimijikelezo emfutshane, ukukhusela zombini i-wiring kunye nezixhobo ezixhunyiwe.

 

Imimiselo yohambo oluhlengahlengiswayo

Ii-MCCB ezininzi zixhotyiswe ngezicwangciso zohambo olulungelelanisiweyo, ezivumela umsebenzisi ukuba alungise kakuhle impendulo ye-breaker kwi-overloads kunye neesekethe ezimfutshane. Olu lungelelwaniso lwenza ukuba i-breaker iqulunqwe ngokweempawu ezithile zenkqubo yombane, ukuphucula ukukhuselwa ngaphandle kokuncama ukusebenza kakuhle.
