Izixazululo Zakho Zokukhiqiza I-MCCB
I-ARM3E
I-ARM3E Series yohlobo lwe-elekthronikhi uhlobo olulungisekayo oluguquguqukayo Ikesi Elibunjiwe I-Circuit Breaker 400V/690V 250A 3/4 izigxobo Ezakhelwe ku-LSIG Trip Unit
Amaphuzu avelele e-MCCB
Izinzuzo kanye namaphuzu avelele wemishini yenqubo yokushisela yezingxenye zehadiwe zohlobo lwe-MCCB Electronic
1. I-Acereare inokuncintisana okuyisisekelo kokushisela, futhi isebenzisa okokusebenza okuzenzakalelayo ngokugcwele ukuze yamukele kalula izinqubo zokushisela izingxenye ezivela kuzo zonke izigaba zokuphila.
2. Inqubo yokushisela kufanele ifane. Ukucubungula ama-electrode asezingeni, ukusetshenziswa okujwayelekile kwama-electrode, ukugcinwa okujwayelekile kwama-electrode kanye nokuphathwa kwedatha okujwayelekile kuyixazulula ngokuphelele inkinga yenqubo yokushisela engazinzile Inenani lobuchwepheshe bezinqubo ezibalulekile. Okufana nenqubo ye-brazing yokumelana nokushisa okungaqondile, inqubo yokufaka i-induction brazing kanye ne-othomathikhi yokushisela ngemva kokugaya (ngezinkinga zokushisela zezinto ezahlukene).
3. Ubuchwepheshe bokulawula izinga lokushisa le-infrared busetshenziselwa ukulawula ngokunembile imingcele yokushisela, okuqinisekisa ikhwalithi yokushisela futhi ithuthukise kakhulu impilo yesevisi yomkhiqizo ngo-50%.
