Abstract

Since SF6 has high liquefaction temperature, the reliability of GIS, GIL and other gas insulated electrical equipment is reduced, and the maintenance cost is high in areas with high latitude. Therefore, applying mixed gas of SF6 and N2 as an insulating medium can reduce the liquefaction temperature of the medium under the precondition of maintaining certain insulation strength. In the paper, a breakdown experimental platform was built to study the insulating property of SF6/N2 at low temperature. A slightly non-uniform electric field was generated by a hemisphere-plate electrode. The breakdown voltage of SF6/N2 with different mixing proportions at different gas pressures under low temperature condition was measured, therefore the influence law of temperature on mixed gas breakdown voltage was analyzed. The result showed that the insulating property of unliquefied mixed gas was not affected by temperature greatly in the slightly non-uniform electric field. The result in the paper has certain reference significance for applying SF6/N2 in GIS and other electrical equipment of high latitude areas.
