This paper presents the effect of pressure on AC flashover characteristic of contaminated suspension insulator strings (unit: 7) and post insulators in a large artificial climatic chamber. The dependence of pollution flashover voltage on pressure has been obtained. The altitude revision factors influenced by pressure on pollution insulating strength of insulators were calculated under light pollution degree.

he relationship between the flashover voltage U of the polluted insulator andthe air pressure p is usually expressed by a formula where U0 is the flashovervoltage of the polluted insulator at the standard atmospheric pressure P0 In this paper several types of insulators with different shapes were tested by the artificial solid pollution layermethod at different air pressures and at different pollution degrees under both AC and DCvoltages. The test results showed that the exponent n at above formula was larger under acvoltage than that under DC voltage. For the insulators with simple shape the exponent n isnot influenced by the pollution degree, but for the insulators with complex shape the value nwas effected by the pollution degree. The reason of n changing is the arcbridging phenomenon between sheds or ribs of insulators at different air pressures.

污秽绝缘子的闪络电压U和大气压力户之间的关系为U=U。(P/p0)n,U0是该污秽绝缘子在标准大气压户。下的闪络电压。作者用固体污层人工污秽试验方法研究了不同形状绝缘子在不同污秽度下以及在不同大气压力下的污闪电压,并研究了在交流和直流电压分别作用下的污闪电压差别。试验结果表明,上述公式中的指数n在交流电压下的数值大于直流电压。对于形状简单的绝缘子n值不受污秽程度影响,对于形状复杂的绝缘子n值受污秽程度的影响。n值变化的原因在于绝缘子伞裙间的电弧桥络现象。
