Umahluko phakathi kwe-AC MCB kunye ne-DC MCB

Umahluko phakathi kweIsixhobo sokwaphula isekethe esincinci se-AC(MCB) kunyeIsixhobo sokwaphula isekethe esincinci se-DC(MCB) yinto ebalulekileyo ekukhuseleni iisekethe. Ukuqonda la mahluko kubalulekile ekukhetheni i-circuit breaker efanelekileyo kwiimfuno zakho ezithile. Njengomntu okhokelayoUmenzi we-MCB, sizimisele ukukunika ulwazi oludingayo ukuze wenze izigqibo ezisekelwe kulwazi.

Okokuqala, makhe sazise iisekethe ezifanelekileyo zezi ntlobo zimbini zee-miniature circuit breakers. Ii-AC miniature circuit breakers zenzelwe ukusetyenziswa kwiisekethe ze-alternating current (AC), ngelixa ii-DC miniature circuit breakers zilungele ngakumbi iisekethe ze-direct current (DC). Oku kungenxa yokuba kukho umahluko omkhulu kwicala lokuhamba kombane kunye notshintsho lwe-voltage kwiisekethe ze-AC kunye ne-DC. Ke ngoko, iintlobo ezahlukeneyo zee-circuit breakers kufuneka ziyilwe kwaye zenziwe ngokukodwa kuhlobo ngalunye lwesekethe.

Ukuqhubeka nengxoxo malunga nendlela ezisebenza ngayo ezi MCB, ii-AC circuit breakers zisebenzisa i-magnetic trigger ukuguqula umbane ohamba nge-coil ube yi-magnetic field. Le magnetic field emva koko ityhala i-iron core ukuze iqalise iswitshi, iphula ngempumelelo i-circuit. Ngokwahlukileyo koko, ii-DC miniature circuit breakers ziphula i-circuit nge-fuse. Xa umbane udlula kwinqanaba elithile, i-fuse iyatshisa kwaye inyibilike, iphazamise i-circuit.

Ngokuphathelele amanqanaba okhuseleko, ii-DC miniature circuit breakers ngokubanzi zibonelela ngenqanaba eliphezulu lokhuseleko kunee-AC circuit breakers. Ngokubanzi, ii-DC miniature circuit breakers kufuneka zihlangabezane nenqanaba lokhuseleko lwe-IP67 ukuqinisekisa ukhuseleko olusebenzayo eluthulini nasemanzini. Kwelinye icala, ii-AC miniature circuit breakers zihlala zifuna kuphela ukufikelela kumlinganiselo wokhuseleko lwe-IP54. La manqanaba okhuseleko abalulekile ekumiseleni ukuthembeka kunye nobomi benkonzo ye-circuit breaker, nto leyo eyenza ukuba ibe yinto ebalulekileyo ekufuneka iqwalaselwe.

Umahluko kuyilo nawo udlala indima ebalulekileyo ekwahlukaniseni ii-AC kunye nee-DC MCB. Ngenxa yokungazinzi kakuhle kwe-voltage yombane ye-DC, i-DC miniature circuit breaker ifuna umbane ozinzileyo ukuqinisekisa ukusebenza kwayo okuqhelekileyo. Ukongeza, ii-DC MCB kufuneka zibonakalise uzinzo olungcono lobushushu kunye nokuqina ukuze kuthintelwe naluphi na uhlaselo lokusilela kuyo yonke inkqubo. Oku kugxininisa ukubaluleka kokukhetha ii-MCB ezenzelwe ngokukodwa iisekethe ze-DC, njengoko zenzelwe ukumelana nemingeni eyahlukileyo evezwa ziinkqubo zamandla ze-DC.

Ukushwankathela, umahluko ophambili phakathi kwee-AC miniature circuit breakers kunye nee-DC miniature circuit breakers usekwe kwisekethe efanelekileyo, umgaqo wokusebenza, inqanaba lokhuseleko kunye noyilo. Xa ukhetha phakathi kwezi ntlobo zimbini zee-MCB, kufuneka kuqwalaselwe iimeko ezithile zokusetyenziswa kunye neemfuno zenkqubo yombane. Njengomvelisi we-MCB othembekileyo, sinokukunceda ukhethe i-circuit breaker efanela iimfuno zakho, ukuqinisekisa ukhuseleko olufanelekileyo lwesekethe kunye noxolo lwengqondo.
