Indima ye-MCB

I-Miniature circuit breaker (I-MCB) zidlala indima ebalulekile ekuqinisekiseni ukuphepha nokuvikelwa kwezinto zasekhaya kanye nemishini kagesi. Ama-Miniature circuit breaker asetshenziswa kabanzi ukuvimbela ukugcwala ngokweqile, ama-short circuit kanye nokuvuza, ngaleyo ndlela avikele imishini ekulimaleni futhi anciphise ukusetshenziswa kwamandla. Ubukhulu bayo obuncane, ukulula kokufakwa, ukuthembeka okuphezulu kanye nokusebenza kahle kwezindleko kuyenza ibe yingxenye ebalulekile ezinhlelweni zikagesi.

Omunye wemisebenzi ebalulekile yama-MCB ukuhlinzeka ngokuvikelwa kwesekethe emfushane. Uma kwenzeka iphutha lesekethe emfushane futhi ugesi olayini umkhulu kakhulu, i-miniature circuit breaker isebenzisa amandla kagesi akhiqizwa yi-electromagnetic coil ukushayela i-iron core, icindezele induku yokucindezela ukuvula, futhi inqamule isekethe ngesikhathi esifushane. Ngaphansi kwemizuzwana engu-0.1. Lokhu kusabela okusheshayo emaphutheni esekethe emfushane kusiza ukuvimbela ukulimala okungenzeka emishinini futhi kuqinisekisa ukuphepha kwezinhlelo zikagesi.

Ngaphezu kokuvikelwa kwesekethe esifushane, ama-MCB aklanyelwe futhi ukuhlinzeka ngokuvikelwa kokulayisha ngokweqile. Uma ugesi olayini udlula ugesi olinganiselwe kodwa usephansi kunenani lamanje lesekethe esifushane elibekiwe, okubangela iphutha lokulayisha ngokweqile, isici se-bimetallic esishisayo ku-miniature circuit breaker siyagoba futhi simelane nokukhiya, ngaleyo ndlela siphule ugesi. Isikhathi sokuphuka siyashintsha ngokuya ngobukhulu bogesi olayisha ngokweqile, futhi osayizi bamanje abahlukene bahambisana namazinga ahlukene okulibaziseka. Lesi sici sisiza ukuvimbela imishini ekushiseni ngokweqile kanye nomonakalo ongaba khona obangelwa ukulayisha ngokweqile isikhathi eside.

Uma ucabangela amandla okuphula ama-MCB, kubalulekile ukuqaphela ukuthi aklanyelwe ukwamukela ububanzi bamandla okuphula isekethe esifushane. Umthamo wokuphula isekethe esifushane (Icn) olinganiselwe wama-circuit breaker amancane ajwayelekile uvame ukuba ngu-6A kuya ku-63A, lapho amandla okuphula ama-circuit breaker amancane angu-6A kuya ku-40A angu-6KA, kanti amandla okuphula ama-circuit breaker amancane angu-50A kuya ku-63A angu-4.5KA. Ngaphezu kwalokho, amandla okuphula isekethe esifushane (Ics) asebenzayo nawo achazwe njengo-6KA wama-circuit breaker amancane angu-6A kuya ku-40A kanye no-4.5KA wama-circuit breaker amancane angu-50A kuya ku-63A. Lawa makhono okuphula aqinisekisa ukuthi ama-circuit breaker amancane angaphazamisa isekethe ngokuphephile ngaphansi kwezimo ezahlukahlukene zesekethe esifushane, enezela ungqimba lokuvikela ezinhlelweni zikagesi.

Ukuguquguquka nokusebenza kahle kwe-MCB kwenza kube yingxenye ebalulekile yokuvikela izinto zasekhaya kanye nemishini kagesi. Amandla okuvikela ukulayisha ngokweqile, ama-short circuit kanye nokuvuza awagcini nje ngokuvikela imishini kodwa futhi asiza ekunciphiseni ukusetshenziswa kwamandla. Ama-MCB mancane, kulula ukuwafaka, athembekile kakhulu futhi ayathengeka, ahlinzeka ngesisombululo esingabizi kakhulu sokuqinisekisa ukuphepha nokuvikelwa kwezinhlelo zikagesi. Kungakhathaliseki ukuthi kuyindawo yokuhlala, yezentengiselwano noma yezimboni, ama-miniature circuit breaker abalulekile ekugcineni ubuqotho nokuphepha kokufakwa kukagesi.

I-Mutai Group iqoqe iminyaka engaphezu kweyishumi yesipiliyoni sokukhiqiza nokuthengisa e-USama-circuit breaker, ama-contactor, amaswishi okudlulisa okuzenzakalelayo anamandla amabili (I-ATS) kanye nezinkambu ezihlobene. Silangazelela ithuba lokusebenza nawe.
