Umahluko phakathi kwe-ACB kunye ne-MCCB

Isixhobo sokwaphula isekethe yomoya (I-ACBkunyeiqhekeza lesekethe elibunjiweyo (I-MCCB) zizixhobo ezimbini zokukhusela iisekethe ezisetyenziswa kakhulu kwiinkqubo zombane. Nangona zombini zisebenza umsebenzi osisiseko wokukhusela iisekethe kwimithwalo egqithisileyo, iisekethe ezimfutshane, kunye nezinye iimpazamo, kukho umahluko ophambili phakathi kwezi zimbini ezenza zifaneleke kwiindlela ezahlukeneyo zokusebenza.

Okokuqala, ubukhulu be-ACB kunye ne-MCCB bahluke kakhulu. Ii-ACB zikhulu ngobukhulu nangomthamo kwaye zinezilinganiso zangoku eziqala kwi-400A ukuya kwi-6300A. Oku kuzenza zilungele ukusetyenziswa kwiinethiwekhi zokusasaza amandla, apho umsebenzi wazo kukusasaza amandla ombane kunye nokukhusela imigca kunye nezixhobo zombane kwiimpazamo ezahlukeneyo. Ii-MCCB, kwelinye icala, zincinci ngobukhulu nangomthamo kwaye zinezilinganiso zangoku eziqala kwi-10A ukuya kwi-800A. Zisetyenziswa rhoqo ukukhusela imigca yokusasaza kunye nezixhobo kwimithwalo engaphezulu, iisekethe ezimfutshane kunye ne-undervoltages, kwaye zinokukhusela imisebenzi yokuqalisa iimoto.

Omnye umahluko obalulekileyo phakathi kwe-ACB kunye ne-MCCB ngumsebenzi wazo wokukhusela. I-tripper ekrelekrele ye-air circuit breaker inemisebenzi emininzi yokukhusela efana nokukhusela ukulibaziseka kwexesha elide, ukukhusela ukulibaziseka kwexesha elifutshane, ukukhusela kwangoko, ukukhusela umhlaba, ukukhusela i-overvoltage, kunye nokukhusela ukulahleka kwesigaba. Ukongeza kwimisebenzi yokukhusela, i-ACB ikwabonelela ngemisebenzi yokulinganisa efana nokulinganisa okwangoku, ukulinganisa i-voltage, ukulinganisa amandla, kunye nokulinganisa i-harmonic, kunye nemisebenzi yokuncedisa efana nokulumkisa kwangethuba, ukuzixilonga, ukurekhoda imbali yempazamo, kunye nemisebenzi yovavanyo. Ukongeza, i-ACB ixhotyiswe ngezakhono zonxibelelwano ezivumela ukuhlanganiswa okungenamthungo kwinkqubo ebanzi yombane. Ngokwahlukileyo koko, ii-molded case circuit breakers ikakhulu zibonelela ngokhuseleko lwexesha elide, ukhuseleko lwexesha elifutshane (ukhuseleko lomthwalo ogqithisileyo) kunye nokhuseleko olukhawulezileyo (ukhuseleko lwe-short-circuit).

Ububanzi bokusetyenziswa kwe-ACB kunye ne-MCCB nabo bahlukile. I-ACB isetyenziswa kakhulu kwiinethiwekhi ezinkulu zokusasaza amandla ngenxa yomthamo wayo wamandla aphezulu kunye noluhlu olubanzi lwemisebenzi yokukhusela. Zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza okuthembekileyo nokukhuselekileyo kweenkqubo zombane ngokuthintela iimpazamo ezahlukeneyo kunye nokungaqhelekanga. Kwelinye icala, ii-MCCB zisetyenziswa kwiindawo zorhwebo kunye nezoshishino apho umthamo wamandla wamandla aphantsi wanele ukukhusela ukugqithisa, ii-short circuits, kunye ne-undervoltages. Zihlala zisetyenziselwa ukukhusela imigca yokusasaza kunye nezixhobo kunye nokubonelela ngokhuseleko kwimisebenzi yokuqalisa iimoto.

Ngamafutshane, umahluko phakathi kwe-ACB kunye ne-MCCB unokubangelwa bubungakanani bazo, imisebenzi yokukhusela kunye nobubanzi besicelo. I-ACB inkulu ngobukhulu kwaye inokubonelela ngemisebenzi yokukhusela epheleleyo kunye nokulinganisa kwaye ifanelekile ukusetyenziswa kwiinethiwekhi zokusasaza umbane, ngelixa i-MCCB incinci kwaye inokubonelela ngemisebenzi yokukhusela efunekayo kwimigca emincinci yokusasaza kunye nezixhobo. Ukuqonda la mahluko kubalulekile ekukhetheni isixhobo sokukhusela isekethe esifanelekileyo kwinkqubo yombane ethile, ukuqinisekisa ukusebenza kakuhle kunye nokhuseleko.
