Aiki fesu ɗaya na tsohu tsakiyar jirgin ruwa 12...24 kV, 630...1250A, 12...25 kA

General：

Muhimmanci karamin VD4 na circuit-breakers suna cikin vacuum don samar da shiga. Da yake ina buƙata ROCKWILL don hanyoyi masu inganci. Muhimmanci karamin VD4-R na medium voltage vacuum circuit-breakers tare da lateral operating mechanism don samar da shiga suna da siffar tekuniya ta bincike. Kowane pole na iya zama da vacuum interrupter wanda ya kasance a cikin resin idan cylinder ya fito da sabon inganci. Wannan siffar har zuwa ya magance vacuum interrupter daga tsirrai, cuta da juyin ruwa. Operating mechanism ce ta free stored energy type tare da independent opening and closing baɗe ne a yi aiki. Mechanism ce ta fiye da amfani a duk muhimmanci karamin VD4-R na circuit-breakers tare da frontal control. Circuit-breaker yana iya zama da remote control idan an kara da electrical accessories (gearmotor, opening and closing release).

Operating mechanism, uku poles da current sensors (idandanan) suna sa a metal frame bace da wheels. Siffar har zuwa ce mai kyau, gaskiya da kadan weight. Muhimmanci karamin VD4-R na circuit-breakers tare da lateral operating mechanisms suna da sealed pressure devices ta hanyar rana. (Standards IEC 62271-100)

Main technical data：

Muhimmanci karamin teknikal suna bayyana electrical parameter configurations, mechanical performance parameters, da dimensional details don in ba da precise system integration da application planning.
