Abstract: As an environmentally friendly gas, Nitrogen gas has received close attention recently in the field of gas insulated switchgear due to its stable physical and chemical properties. The power frequency voltage withstand test and lighting impulse voltage withstand test were conducted in lower pressure for the pure N2 gas in non-columniforn electrodes which was commonly used in gas insulated switchgear, and the test result underwent a multi-angled analysis.The curve-fitting method was used to obtain the experiential formula of the relationship between breakdown voltage Ub and p×d in lower pressure. The research result is significant in guiding the research and development of nitrogen
insulated switchgear.
Key words: gas insulated switchgear; environmentally friendly gase; N2; insulation performance
