Micafluid sf6 device for transformers

Jul 29, 2019 · For systems with high fault potential, where power fuses are not appropriate, the use of SF6 gas is still the primary arc extinguishing medium used in transformer protective devices. It is not unusual for a circuit breaker to require 80 lbs. of SF6 gas.

  • Products - SF6-gas Gasbanor (Switzerland) GmbH, Micafluid

    SF 6 –gas is a non-toxic, non-flammable, stable compound. Its breakdown voltage is approximately 2.5 times higher than normal air, as the electro-negative SF 6 –molecule has a strong affinity to free electrons. It has over 100 times better arc quenching capability and significant better heat dissipation than air (N 2 ).

  • Transformer - Wikipedia

    A transformer is a passive electrical device that transfers electrical energy from one electrical circuit to another, or multiple circuits.A varying current in any one coil of the transformer produces a varying magnetic flux in the transformercore, which induces a varying electromotive force across any other coils wound around the same core.
