II-HM4 medium-voltage circuit breakerukusetshenziswaigesi yesulfure hexafluoride (SF6)njengendlela yokucima i-arc kanye ne-insulation medium.
Igesi le-SF6inezici zokuphuka ezibushelelezi, futhi uma iphula ugesi kuwo, akukho mkhuba wokunquma ugesi futhi akukho ugesi odlulayo okhiqizwayo.
Lokhuisici esihle kakhulukuqinisekisa ukuthi i-circuit breaker iphila isikhathi eside kagesi.
Ngaphezu kwalokho, ngesikhathi sokusebenza, akunawo umthelela ekushaqekeni kwemishini, ezingeni le-dielectric, kanye nokucindezeleka kokushisa.
Ikholomu yesigxobo se-circuit breaker, okungukuthi, ingxenye yegumbi lokucisha i-arc, iyisistimu evaliwe engenakho ukulungiswa impilo yonke. Isikhathi sayo sokuvala sihambisana nezindinganiso ze-IEC 62271-100 kanye ne-CEI17-1.
