1. Overview:
A series of indoor AC high-voltage vacuum contactors, divided into two types: mechanical closing and electromagnetic holding. This contactor is suitable for power systems with three-phase AC, rated voltage and current up to 3, for connecting and breaking lines over long distances, and controlling electrical equipment such as high-voltage motors, transformers and capacitive loads. It is especially suitable for various applications. Frequent operation areas. The contactor is small in size and light in weight. It adopts the internationally popular assembled structure of upper and lower arrangement. It is easy to use and maintain and is easy to form a complete set of circuit equipment.
2. Environmental conditions
) The upper limit of ambient air temperature +, the lower limit: - the altitude does not exceed
b) Humidity: the daily average of relative humidity is not greater than that, and the monthly average is not greater than that of water vapor pressure The average value is not greater than ., and the monthly average value is not greater than . The surrounding air should not be significantly polluted by corrosive gases, water vapor, etc.
) No frequent violent vibrations. When the contactor is running, the inclination angle of the installation plane to the horizontal should not be greater than
