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 50Hz
This 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 transformer
1.normal operating conditions
a)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 ignored
c)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.
