Definitions

  • the downstream valve (which is open during normal operation) can be dispensed with and the liquid can be drained into the inert gas container, its contents, if there is a risk of fire to the transformer.
  • the gas which is kept available, meaningfully nitrogen, can possibly be kept under negative pressure in order to avoid the creation of a strong excess pressure in the system of the transformer and gas container which communicates after liquid evacuation has occurred during the fire.
  • the shut-off valve for the inert gas would be opened with a corresponding delay.
  • insulating liquids up to approximately 95% of the filling quantity unlike solids or gases, can thus be made fire-unreliable by applying simple hydraulic-pneumatic laws.
  • the arrangement described is particularly useful for transformers that do not have a statistically quantifiable fire-causing potential, as is the case for transformers filled with K liquids.
