Maintenance of sf6 gas recovery Decomposition

With a response time of <15 seconds, self-sealing hoses and couplings, along with connections for discharge recovery systems, the SF 6 arc by-products analyzer is user friendly and emission free. During the operation of gas insulated switchgear decomposition products (SO2/SOF2) might occur after a breakdown, which has a negative impact on the gas quality in the circuit breaker as well as on the insulation properties.

  • SF6 gas handling - DILO

    A service cart enables the recovery of the SF 6 gas from a gas compartment to a final vacuum of < 1 mbar. Thereby the gas flows automatically via dry and particle filters which effectively adsorb decomposition products and moisture from the gas. During the gas recovery process the SF 6 is stored either in gaseous or in liquid form. Furthermore, the air is evacuated from gas compartments after maintenance works.

  • SF Maintenance Equipment Fundamentals

    6 gas recovery systems are used in several capacities: as a means to store the gas during GIE maintenance, to clean and dry the gas, and to perform cylinder consolidation. Various technologies exist that can achieve similar results. Compressed to liquid form, larger amounts of SF 6 can be stored in smaller volume storage containers.

  • Drying and particle filters absorb moisture, gas and dust

    On the suspicion that SF 6 gas in a circuit breaker is contaminated or humid, we strongly recommend the use of drying and particle filters between switchgear and service cart. Moisture and both gaseous and dusty decomposition products as well as oil aerosols are adsorbed by special drying and particle filters during the recovery operation. Thus, service carts are protected effectively against contamination as most of the moisture and decomposition products are collected by the prefilter units.
