I-MCCB VS MCB vs Rcbo: Zithetha ukuthini?

I-MCCB ngumphuli wesekethe oxutywe, kwaye i-MCB ingumphunga wesekethe ongumbhobho. Zombini zisetyenziswa kwimijikelezo yombane ukubonelela ngokhuseleko olugqithisileyo. I-MCCB isetyenziswa rhoqo kwiinkqubo ezinkulu, ngelixa i-MCBs isetyenziswa kwimijikelezo emincinci.

I-RCB yindibaniselwano ye-MCCB kunye ne-MCB. Isetyenziswa kwiisekethe ezijikelezayo apho obolekayo kwaye ukhuseleko lwesekethe luyafuneka. I-RCBOs ingaqhelekanga kune-MCCBs okanye i-MCBS, kodwa ziyakhula ngokuthandwa ngenxa yokwazi kwabo ukubonelela ngeentlobo zokukhusela ezimbini kwisixhobo esinye.

I-MCCBs, i-MCBS, kunye ne-RCBs Zonke zisebenzela umsebenzi ofanayo wesiseko: ukukhusela imijikelezo yombane kumonakalo ngenxa yeemeko ezikhoyo. Nangona kunjalo, ngamnye anezibonelelo zabo kwaye angabakholisanga. I-MCCB zezona zinkulu kwaye zibiza kakhulu kwezi ndlela zintathu, kodwa zinokuphatha imijikelezo ephezulu kwaye zibe nexesha elide lobomi.

I-MCBS incinci kwaye ingabizi kakhulu, kodwa inomphakamo ofutshane kwaye unokuphatha kuphela imijikelezo esezantsi.I-RCBOs yeyona nto iphambiliInketho, kwaye banikezela ngezibonelelo ze-MCCB ze-MCCB kunye ne-MCBS kwisixhobo esinye.

Xa kukho ukungaqhelekanga okufunyanwa kwisekethe, i-MCB okanye i-MCB okanye i-MAITAT STACHE CRACLE ngokuzenzekelayo icocwe. I-MCBS yenzelwe ukucaca ngokulula xa kukho indawo egqithisileyo, eyenzeka rhoqo xa kukho isiphaluka esifutshane.

Isebenza njani i-MCB? Zimbini iintlobo zabafowunelwa kwi-MCB-enye ilungisiwe kwaye enye isusiwe. Xa ukuqukuqela kwangoku ngokunyuka kwesekethe, kubangela ukuba abafowunelwa abanokususwa ukuba bakhuphe oonxibelelwano olumiselweyo. Oku "kuvula" isekethe kwaye uyeke ukuhamba kombane ukusuka ekuboneleleni kakhulu. Ngamanye amagama, i-MCB isebenza njengenqanaba lokhuseleko lokukhusela isekethe ekumdlayo ophathekayo kunye nomonakalo.

I-MCCB (i-Polded Forteaker yesekethe)

I-MCCB zenzelwe ukukhusela isekethe yakho ekugcwaliseni okungaphezulu. Babonisa amalungiselelo amabini: enye i-overcurirenting kwaye enye yeqondo lokushisa. I-MCCB isebenza ngokutshintsha ngesandla ukuba ihambele iskepha yesekethe, kunye nonxibelelwano lwe-Bimitallic olwanda okanye ikhontrakthi xa utshintsho lobushushu be-MCCB.

Zonke ezi zinto zihlanganisana ukudala isixhobo esinokuthenjwa, esiqinileyo esinokunceda siqhubeke sikhuselekile. Ndiyabulela kuyilo lwayo, i-MCCB inokuba lukhetho olukhulu lwezicelo ezahlukeneyo.

I-MCCB ngumphuli wesekethe onceda ukukhusela izixhobo kumonakalo ngokukhupha ubonelelo oluphambili xa kungoko ixabisekisile. Xa unyuso lwangoku, abafowunelwa kwi-MCCB banda kwaye bafudumele de bavule, ngaloo ndlela baphule isiphaluka. Oku kuthintela ukonakala ngakumbi ngokufumana izixhobo ezivela kubonelelo oluphambili.

Yintoni eyenza i-MCCB & MCB ifana?

I-MCCB kunye ne-MCBS ingabeki baphula okwenziwa kwisekethe ezibonelela ngento yokhuseleko kwisekethe yamandla. Zisetyenziswa kakhulu kwisekethe ephantsi ye-voltage kwaye zenzelwe ukuqonda nokukhusela isekethe kwiisekethe ezifutshane okanye iimeko ezingaphezulu.

Ngelixa babelana ngezinto ezininzi, ii-MCCC ezisetyenziselwa imijikelezo emikhulu okanye ezo zinemijikelezo ephezulu, ngelixa i-MCBs ilungele imijikelezo emincinci. Zombini iintlobo zecandelo lesekethe zidlala indima ebalulekileyo ekuqinisekiseni ukhuseleko lweenkqubo zombane.

Nguwuphi umahluko mcb ukusuka kwi-MCB?

Umahluko ophambili phakathi kwe-MCB kunye ne-MCCB ngumthamo wazo. I-MCB inomlinganiso ongaphantsi kweminyaka eli-100 phantsi kwe-18,000 ye-Amps iphazamisa umlinganiso we-18,000 ye-Ampcs, ngelixa i-MCCB ibonelela ngama-Amplis njenge-10,500. Ukongeza, i-MCCB ibonisa into esebenzayo yohambo lweemodeli eziphambili ezingaphezulu. Ngenxa yoko, i-MCCB ilungile kakhulu kwisekethe efuna umthamo ophezulu.

Okulandelayo bambalwa umahluko obaluleke ngakumbi phakathi kwezi ntlobo zimbini zeesekethe:

I-MCCB luhlobo oluthile lomphunga osetyenziselwa ukulawula nokukhusela iinkqubo zombane. I-MCBS ikwabophula iSekethe kodwa zahlukile kuba zisetyenziselwa izixhobo zekhaya kunye neemfuno zamandla aphantsi.

I-MCCB zinokusetyenziselwa imimandla ephezulu yokusebenza, enjengamashishini amakhulu.

McbsYiba nesekethe ehleliweyo yokuhamba ngexesha kwi-MCCTS, isekethe yokuhamba iyashukuma.

Ngokwe-AMPS, i-MCBS inama-Amplitha ngaphantsi kwe-100 ngelixa i-MCCTS inokuba phezulu njenge-2500 ye-2500.

Akunakwenzeka ukuba ujike kwaye ucime i-MCB ngelixa kunokwenzeka ukuba wenze i-MCCB ngokusebenzisa i-wire ye-wire.

I-MCCBs isetyenziswa ikakhulu kwiimeko apho kukho i-rough kakhulu ngelixa i-MCBS inokusetyenziswa kuyo nayiphi na isekethe ephantsi yangoku.

Ke, ukuba ufuna ikhefu lesekethe kwikhaya lakho, ungasebenzisa i-MCB kodwa ukuba ufuna enye yendawo yomzi mveliso, ungasebenzisa i-MCCB.
