Load Break Switch/Lbs Breaker

  Product Description  FL(R)N36-12(D) Load switches and combiners (hereinafter referred to as "load switches" and "combiners") are suitable for three-phase ac power systems of 10kV and 50HzThis product as industrial and mining enterprises, high-rise buildings, residential quarters, pre-installed type substation, for the breaking, closing load current, the fault current, control and protection circuit and the power distribution transformer1.normal operating conditionsa)Ambient air temperature is not more than 40 ºC, and at 24 h closed to the average no more than 35 ºC. Minimum ambient air temperature 25 ºC.b)The effects of sunlight can be ignoredc)No more than 3000m above sea level.d)Ambient air is not significantly contaminated by dust, smoke, corrosive and/or flammable gases, vapors, or salt fog. If the user does not have special requirements, the manufacturer may consider that these situations do not exist.e)The humidity conditions are as follows:--The average relative humidity measured within 24h is no more than 95%.--The mean value of water vapor pressure measured within 24h shall not exceed 2.2kPa.--The average monthly relative humidity should not exceed 90%.--The average monthly water vapor pressure does not exceed 1.8kpa. In such conditions appear condensation occasionally.f) The vibration or ground motion from the outside of the switching equipment and the control equipment has no obvious relationship with the normal operation mode of the equipment. If the user has no special requirements, the manufacturer may not consider these situations.GB 3804-2004         3.6KV~40.5KVHigh voltage ac load switchGB 16926-2009        High voltage ac load switch fuse combination electrical applianceGB 11023-1989        Test guide for fln36 gas seal of high pressure switching equipmentGB 1985-2004         High voltage ac isolation switch and ground switchGB/T 11022-2011Common technical requirements for high voltage switching equipment and control equipment standardsProduct Parameters No.    DescriptionUnitDataFLN36-12FLN36-12D1Rated VoltagekV122Rated CurrentA6301253Load switch rated short - term withstand current/durationkA/s20/3Ground switch rated short - term withstand current/durationkA/s20/24Rated peak withstand current and short circuit closing currentkA50125(Expect)5Rated active load switching currentA6306Rated closed loop breaking currentA63075% rated active load open currentA31.58Rated cable charging currentA109Rated capacity of open - break no-load transformerkVA125010Rated transfer open currentA 170011Rated expected short circuit open currentkA 5012Rated insulation level   1min working frequency withstand voltage phase to ground/breakkV42/48Lightning shock withstand voltage alternate, ground - to - ground/breakkV75/8513Mechanical endurance 500014SF6 pressure rating (20 ºC)MPa0.04 ~0.0515Rated operating voltage of electric mechanismVAC/DC22016Power frequency withstand voltage of secondary line 1minV200017Air leak rate/Year
