I-Miniature Circuit Breaker JCB3 63DC1000V DC: Ukuvikelwa Okuthembekile Kwezinhlelo Zamandla we-DC

Emhlabeni wanamuhla, i-DC (Direct yamanje) isetshenziswa kabanzi ezinhlelweni zamandla elanga, ukugcinwa kwebhethri, imoto kagesi (eV) ukushaja, ukuxhumana ngocingo, kanye nezicelo zezimboni. Njengoba izimboni eziningi kanye nabanini khaya baguqukela ekuvuseleleni izixazululo zamandla, isidingo sokuvikelwa kweseketheli esithembekile akukaze kube mkhulu.

 

Le khasiI-JCB3-63DC1000V DC Miniature Breaker (MCB)Ingabe idivaysi esebenza kahle yokuzivikela eyenzelwe izinhlelo zokusebenza zamandla we-DC. Ngomthamo wayo ophakeme (6ka), ukwakheka okungewona ama-polarised, ukumiswa kwezikhwama eziningi, kanye nokuhambisana namazinga okuphepha we-IEC, kuqinisekisa ukuphepha okuphezulu nokusebenza kahle.

 

Lo mhlahlandlela uzohlola ukubaluleka kokuvikelwa kwesifunda i-DC, izici ezibalulekile, izinhlelo zokusebenza, izinzuzo, imihlahlandlela yokufaka, amathiphu wesondlo, kanye nokuqhathanisa namanye ama-MCB.

 

Kungani Kuvikelwa Ukuvikelwa Kwezifundo ze-DC

 

Ama-DC Power Systems asetshenziswa kakhulu ekufakweni kwe-solar Photovoltaic (PV), izixazululo zamandla ezipele izipele, izimoto zikagesi, kanye nezinto ezenziwa ezimbonini. Kodwa-ke, amaphutha we-DC ayingozi kakhulu kunamaphutha we-AC ngoba ama-ARC we-DC anzima ukuyicisha.

Uma umjikelezo omfishane noma ogcwele ngokweqile kwenzeka, kungaholela ku:

 

✔ Ukulimala kwemishini - Ukushisa ngokweqile kanye nokuhlinzwa kwamandla kunganciphisa isikhathi sokuphila kwezakhi ezibizayo.

Izingozi zomlilo - Imisinga eqhubekayo ye-DC ingaxhasa ama-arc kagesi, yandisa ingozi yomlilo.

✔ Ukwehluleka kwesistimu - uhlelo olungavikelekile lungathola ukulahleka kwamandla okuphelele, okwenza isikhathi sokuphumula kanye nokulungiswa okubizayo.

 

I-DC yezemidlalo esezingeni eliphakeme, njenge-JCB3-63DC, ibalulekile ekuqinisekiseni ukuphepha, ukuvikela ukulimala okubizayo, nokugcina ukuhamba kwamandla okungaphazamiseki.

 

Izici ezibalulekile zeJCB3-63DC MCB

 

I-JCB3-63DC DC miniature Breaker Breaker inikezela ngezici eziningi ezenza kube ukukhetha okuphezulu kochwepheshe abasebenza nezinhlelo zamandla aphezulu we-DC.
