Breakdown characteristics of CF3I/N2/CO2 mixture in power

Trifluoroiodomethane (CF 3 I) and its mixtures are believed to be prospective alternatives to sulfur hexafluoride (SF 6), which has been included as a greenhouse gas.In this paper, the breakdown properties of a CF 3 I/N 2 /CO 2 mixture with the volume fraction of CF 3 I fixed at 10% are investigated under power frequency and lightning impulse voltages. The experimental result shows that N 2

SF6 Gas Insulated Transformers - Mitsubishi Electric

22kV/390V 1500kVA SF6 Gas-Insulated Transformer Mitsubishi Electric Power Products, Inc. (MEPPI) supplies SF6 gas-insulated transformers for appliions where a non-flammable, non-polluting transformer is desired, such as in densely populated areas, inside buildings, and in areas near lakes and rivers where potential oil leakage from a conventional transformer would be harmful to the environment.

Decomposition Characteristics of SF6 under Flashover

In this paper, the flashover discharging experiment was carried out on epoxy resin surface in an SF6 atmosphere under pin-plate electrodes, with the electrodes distance from 5 mm to 9 mm. The concentration of seven characteristic gases was detected, indiing that the concentration of SOF2 and CF4 was the two highest, followed by SO2, CO2, SO2F2, CS2, and H2S.

Dielectric gas - Wikipedia

A dielectric gas, or insulating gas, is a dielectric material in gaseous state. Its main purpose is to prevent or rapidly quench electric discharges.Dielectric gases are used as electrical insulators in high voltage appliions, e.g. transformers, circuit breakers (namely sulfur hexafluoride circuit breakers), switchgear (namely high voltage switchgear), radar waveguides, etc.
