Ukuqonda Ukuphulwa Kwekhono Lama-MCB

Ezweni lokuphepha kukagesi, imininingwane emincane ivame ukwenza umehluko omkhulu. Eminye imininingwane enjalo—evame ukungaqondwa kahle noma enganakwa—ukwephulwa kwamandla e-MCB. Uma usebenza ekufakeni, ekulungiseni, noma ekuklanyweni kwesistimu, ukuqonda le methrikhi eyisihluthulelo kungase kuvimbele ukulimala okubi kakhulu kwemishini—noma okubi nakakhulu, izingozi zikagesi.

What does Breaking Capacity ofI-MCBKusho ukuthini ngempela?

Kalula nje, amandla okuphuka kwe-MCB (Miniature Circuit Breaker) ibhekisela kumthamo wamanje ongawuphazamisa ngokuphephile ngaphandle kokudala umonakalo kuyona noma ohlelweni lukagesi. Kuyikhono le-circuit breaker ukumisa ukugeleza kukagesi phakathi nesekhethi emfushane noma isimo sephutha.

Uma kwenzeka ukulimala okungazelelwe noma iphutha, i-MCB kufanele ithathe isinyathelo ngokushesha. Uma i-current idlula umthamo wokuphuka kwesilinganiso sokuphuka, idivayisi ingase yehluleke—okungase kuholele emiphumeleni eyinhlekelele njengomlilo, ama-arcing, noma ukwehluleka kwemishini. Kungakho ukuqonda nokukhetha ngendlela efanele umthamo wokuphuka kubalulekile.

Ukubaluleka Kokukhetha Ikhono Elifanele Lokuphulwa

1. Ukuphepha Kuqala

I-MCB enamandla okuphuka anganele ingase ingakwazi ukubhekana nephutha eliphezulu, okubeka engcupheni ukulimala kukho kokubili isekethe nakubantu abayisebenzisayo. Ukukhetha kahle kuqinisekisa ukuthi idivayisi izohamba kahle ngaphandle kokuqhuma noma ukuncibilika.

2. Ukuhambisana Namazinga Kagesi

Amakhodi kagesi ezifundeni eziningi agunyaza ukuthi amandla okuphuka kwama-MCB kufanele abe makhulu noma alingane nomkhawulo wamanje wesekethe emfishane ongase ube khona endaweni yokufaka. Ukwehluleka ukuhlangabezana nalawa mazinga kungaholela ekungathobelini kanye nezinkinga zomthetho ezingaba khona.

3. Ukwethembeka Kwesistimu

Ama-MCB akalwe kahle awavikeli nje izintambo nezinto zikagesi kuphela kodwa futhi anomthelela ekuzinzeni okuphelele kohlelo lukagesi. Isikhathi sokuphumula ngenxa yeziqephu ezilinganiselwe ngokungafanele zingaholela ekulahlekelweni kokukhiqiza kanye nokulungiswa okumba eqolo.

Izici Ezithonya Ikhono Lokuphulwa

1. Indawo Yokufaka

Izinga lephutha endaweni lapho i-MCB ifakiwe idlala indima enkulu. Ukufakwa kwasemadolobheni noma lezo eziseduze nomthombo wamandla zingase zibe namaphutha aphezulu.

2. Uhlobo Lohlelo Lokusebenza

Izimo zezimboni ngokuvamile zidinga ama-MCB anesilinganiso esiphezulu kunezindawo zokuhlala noma izicelo zokuthengisa ezilula ngenxa yemithwalo esindayo kanye nezinhlelo eziyinkimbinkimbi kakhulu.

3. Ukuklama Uhlelo

Idizayini iyonke yenethiwekhi—okuhlanganisa nosayizi wekhebula, umthamo we-transformer, nebanga elisuka kumthombo wokunikezela—konke kungathinta amandla okuphuka adingekayo we-MCB.

Ungalithola Kanjani Ikhono Elifanele Lokuphulwa Kwezidingo Zakho

Ukukhetha umthamo ofanele wokuphuka we-MCB kuhilela ukuhlola iphutha lamanje endaweni yokufaka. Lokhu kuvame ukubalwa ngokusekelwe ekubambeni kwesistimu noma kuqinisekiswe kusetshenziswa idatha evela kumhlinzeki wosizo.

Nazi ezinye izilinganiso ezijwayelekile zokuphulwa kwamandla ongahlangabezana nazo:

6kA (6000 Amps) – Okujwayelekile kuzilungiselelo zezentengiselwano zendawo yokuhlala noma ezinobungozi obuncane

I-10kA (10000 Amps) - Ifanele ukusetha kokuthengisa okuphezulu noma okulula kwezimboni

I-16kA nangaphezulu - Iyadingeka ezindaweni zezimboni ezisindayo noma ukufakwa okunamandla okujikeleza isikhashana

Hlala uthintana nonjiniyela kagesi oqeqeshiwe ukuze uqinisekise ukubala nokukhetha okufanele.

Isondlo Nokuhlolwa Kwezikhathi: Ungakweqi

Ngisho nama-MCB anesilinganiso esihle kakhulu adinga ukuhlolwa ngezikhathi ezithile. Uthuli, ukugqwala, noma ukukhathala kwangaphakathi kunganciphisa ukusebenza kwazo ngokuhamba kwesikhathi. Ukuhlolwa okuvamile nokugcinwa kokuvikela kuqinisekisa ukuthi amandla okuphuka kwama-MCB ahlala eqinile futhi ethembekile.

Imicabango Yokugcina: Yenza Izinqumo Ezinolwazi Zokuvikela Uhlelo Lwakho

Amandla okuphuka kwe-MCB akuwona nje imininingwane yobuchwepheshe—kuyisici esibalulekile ekuqinisekiseni ukuphepha, ukusebenza, nokuhambisana kunoma yiluphi uhlelo lukagesi. Ukuthatha isikhathi sokuqonda nokusebenzisa kahle lo mqondo kungonga imali, isikhathi sokuphumula, ngisho nezimpilo.
