Umahluko phakathi kwe-DC MCCB kunye ne-AC MCCB

Kwihlabathi lanamhlanje eliphucukileyo kwezobuchwepheshe, ukhuseleko lombane lubaluleke kakhulu. Ke ngoko, kubalulekile ukuqonda umahluko phakathi kweDCI-MCCB (Umqhekezi weSekethe yeTyala eliQokelelweyo) kunye ne-AC MCCB. Ezi zixhobo zidlala indima ebalulekileyo ekukhuseleni iisekethe kwimithwalo emininzi kunye neesekethe ezimfutshane. Masijonge kwiingxaki zezi ntlobo zimbini zeesekethe eziqhekezayo size siqonde iimpawu zazo ezizodwa.

Okokuqala, masichaze ukuba yintoni i-MCCB. I-MCCB, okanye iMolded Case Circuit Breaker, sisixhobo sokukhusela esenzelwe ukuphazamisa isekethe yombane xa kukho i-overload okanye i-short circuit. Iqulathe iyunithi yokujika kunye nesakhelo, kwaye umsebenzi wayo ophambili kukulawula nokukhusela inkqubo yombane. Isetyenziswa kakhulu kwiindawo ezahlukeneyo zokusebenza kuquka amacandelo okuhlala, orhwebo kunye nemizi-mveliso, nto leyo eyenza ukuba ibe yinxalenye ebalulekileyo yeziseko zophuhliso zamandla ezikhuselekileyo nezithembekileyo.

Ngoku, makhe sijonge umahluko phakathi kwee-AC molded case circuit breakers kunye nee-DC molded case circuit breakers. Umahluko ophambili kukukwazi kwazo ukusebenza kwiintlobo ezahlukeneyo zamandla ombane. Ii-AC MCCB zenzelwe ngokukodwa ukuphatha i-alternating current, uhlobo oluqhelekileyo lwamandla ombane olufumaneka kwiinkqubo ezininzi zombane. Ii-DC MCCB, kwelinye icala, zenzelwe ukuphatha amandla e-DC kwaye zifanelekile kwizicelo ezithile ezifana neenkqubo zelanga, zebhetri kunye ne-traction. Lo mahluko ubalulekileyo kuhlobo lwamandla ombane uvumela ezi circuit breakers ukuba zihlangabezane neemfuno zamandla ezahlukeneyo.

Ukongeza, uyilo kunye nolwakhiwo lwangaphakathi lwee-AC molded case circuit breakers kunye nee-DC molded case circuit breakers nazo zahlukile. I-AC MCCB ineyunithi yokuhamba nge-thermal-magnetic esebenza ngokusebenzisa izinto ezishushu ukufumanisa izinto ezigqithisileyo kunye ne-magnetic ukufumanisa ii-short circuits. Le ndlela yokukhusela kabini iqinisekisa ukusebenza okusebenzayo nokuthembekileyo. Ngokwahlukileyo koko, ii-DC MCCB zihlala zineyunithi yokuhamba nge-elektroniki. Esi sixhobo sisebenzisa ii-elektroniki eziphambili ukubonelela ngokhuseleko oluchanekileyo noluchanekileyo ngokuchasene nokugqithisa kunye nee-short circuits kwiinkqubo ze-DC.

Enye into ebalulekileyo ekufuneka iqwalaselwe kukwazi ukuqhekeza i-MCCB. Ukwazi ukuqhekeza kubhekisa kumandla aphezulu okusilela anokuqhekeka yi-circuit breaker ngaphandle kokonakalisa izinto zayo zangaphakathi. Ii-AC MCCB ngokubanzi zenzelwe ukumelana nokuphazamisa amandla aphezulu okusilela njengoko zifanelekile kwiinkqubo zombane ezinkulu. Ngokwahlukileyo koko, ii-DC MCCB zihlala zenziwe ukujongana namandla aphantsi okusilela kuba iinkqubo ze-DC zihlala zine-mandla aphantsi okusilela xa kuthelekiswa neenkqubo ze-AC. Lo mahluko kumandla okusilela uqinisekisa ukhuseleko olufanelekileyo kuhlobo ngalunye lwamandla.

Ukongeza, kubalulekile ukuqaphela ukuba ayizizo zonke ii-MCCB ezifanayo. Abavelisi abahlukeneyo banokuvelisa ii-MCCB ezinemisebenzi eyahlukeneyo kunye namanqanaba okusebenza ahlukeneyo. Xa ukhetha i-molded case circuit breaker, kufuneka kuqwalaselwe izinto ezifana nomgangatho wezinto ezisetyenzisiweyo, ukuthembeka kweyunithi yokuhamba, kunye nodumo lulonke lomenzi. Ukukhetha uphawu oluthembekileyo nolunegama elihle kuqinisekisa ukuba i-MCCB inika ukhuseleko olungcono kwiisekethe zakho kwaye yandisa ubomi bazo.

Ukuqukumbela, ukuqonda umahluko phakathi kwe-DC MCCB kunye ne-AC MCCB kubalulekile kuye nabani na osebenza ngeenkqubo zombane. Umahluko kuhlobo lwangoku, uyilo, ulwakhiwo lwangaphakathi, kunye nobuchule bokuqhekeza kwenza ezi ziqhekeza zesekethe zahluke kwenye kwenye. Ke ngoko, kubalulekile ukukhetha i-MCCB efanelekileyo kwisicelo sakho esithile. Ngokutyala imali kwi-MCCB ethembekileyo nesemgangathweni ophezulu evela kumvelisi othembekileyo, unokuqinisekisa ukhuseleko kunye nokusebenza kwesekethe yakho kwiminyaka ezayo.
