Overview
Optimized interrupting chamber
Basa na faɗiɗa da ake gani game da abubuwa masu shahara ta HEC technology, sabbin yakin HEC Series interrupting chamber wanda ake gina tana ƙunshi shekaru biyu da suka yi nasarar ƙarin bayanai a fadin GCB.
Yana iya koyar zafi mai karfi 300 kA da ma'adinnin karamin zafi 33,500 A, kuma yana da kyau don kula da muhimmanci da take da muhimmiyar generator applications.
Type-tested according to latest standards
HEC Series an saukar da ita a cikin IEC/IEEE 62271-37-013, kafin haka a yi koyar zafi mai karfi da full-phase opposition fault current (180° out-of-phase).
Kuma, an saukar da ita don koyar zafi mai karfi daga generator-source da 160 kA da ya samun delayed current zeros zuwa 130 percent degree of asymmetry a kan G2* class, wanda ke tsakanin turbo generators. Abubuwan da aka bayyana sun fi girma da abubuwan da ake bukata a cikin GCB standard da IEEE C37.013 masu ranar.
Enhanced passive cooling system
Basa na faɗiɗa da ake gani game da abubuwa masu shahara ta passive heat pipe technology masu patent da ba ake buƙata a 20 shekara. An bincika wannan system online da GMS600 don inganta yadda ake amfani da shi.
Fully separated disconnector and interrupting chamber
Duka main da arcing contacts na circuit-breaker suna cikin SF6 don kula da kawo aiki masu shiga da rarraba. Disconnector an fito shi a kan main contacts na circuit-breaker don kula da kawo isolation masu shiga da shiga a kan step-up trans-former da generator. Design na short-stroke yana taimakawa wa HEC 10 compact footprint ba a yi juye ga insulation level.
