outdoor vacuum circuit breaker

1 General state The SC40300 type outdoor vacuum circuit breaker of high voltage ( following abbreviation circuit breaker) can divide into used in the three-phase power system of 50 alternating Hz-12 kVs the load current that joins circuit , overload current and the fault current of short circuit, the room control of electrical network is protected equipment after circuit breaker and switch-disconnector are made up ( following abbreviation combination circuit breaker), page may use as section switch.

2 Operating ambient conditions a. Environmental temperature - 40 °C ~ + 40 °C b.Elevation does not exceed 2000 mm and 2000 mm more negotiate with user C. wind pressure does not exceed 700 Pas ( is equivalent to the 34 m/ses of wind speed); d. The daily mean of relative humidity does not be larger than 95%, mean monthly value does not be larger than 90% e. Air filthy level Ⅲ level f. Around air should not get corrosivity gas or combustibility gas and other obvious pollution; g. Without regular violent sport; h As the silicon rubber of insulation medium, should accord with GB655 386, concerning make application suit ask.
