摘要
研究了在不同的主绝缘厚度下气隙放电的极限气隙间距和极限起始放电电压(有效值)。结果表明,当主绝缘厚度从3mm增加到7mm时,放电气隙的极限间距从309μm或431μm变化至595μm或667μm,极限起始放电电压从3.52kV或4.76kV增加到6.52kV或7.31kV。
The limited air gap distance and limited discharge inception voltage for different thickness of main insulation was studied. The result showed： In case of thickness of main insulation increased from 3mm to 7mm, limited distance for air gap discharge increased from 309μm or 431μm to 595μm or 667μm. while limited discharge inception voltage increased from 3.52kV or 4.76kV to 6.52kV or 7.31kV.
