FAQs:
  • What is SF6 gas and why is it used in this circuit breaker?
    SF6 (Sulfur Hexafluoride) is a colorless, odorless, non-flammable, and non-toxic inert gas known for its excellent insulation and arc extinguishing properties, making it ideal for high-voltage switchgear to ensure safe and efficient operation.
  • What are the key performance specifications of this SF6 load breaker switch?
    This switch operates with a rated current of 630A and a frequency voltage of 42kV, providing safe and reliable performance. It uses SF6 gas at pressures up to 1-1.5 MPa for effective arc extinguishing.
  • How does the SF6 circuit breaker handle arc extinguishing?
    The breaker uses high-pressure SF6 gas to create airflow that blows out the arc in the extinguishing chamber. This method, combined with SF6's insulating strength, ensures quick and reliable interruption of electrical currents.
  • What maintenance is required for the SF6 gas in this switchgear?
    Regular checks of the SF6 gas pressure against the product's temperature curve are essential during inflation or maintenance to ensure optimal performance and safety, as pressure varies with temperature.
