冰类型 meaning in English
ice types
Examples
- The study results show that the minimum ac flashover voltage decreases with the increase of the ice amount accreted on the insulator surface by an exponential law , and the down - trend of the minimum ac flashover voltage will slow gradually with the bridging of the shed of the insulators by icicles , both the average saturated ice amount and the special exponent m of effect of ice amount for different insulators depend on the radius of shed and the air - gaps of the sheds of the insulators , and that the ac ice flashover voltage decrease with the decrease pressure ratio p / p0 ( rise of the altitude ) by power - law for different esdd and icing - states when the altitude is from 4000m to 5500m . the special exponent n , which show the effects of altitude on the flashover voltage , is various with the type of insulator , icing - states and the surface status of iced insulator etc . , and that the minimum ac flashover voltage of iced insulators decreases by power - law with esdd or the freezing water conductivity for different ice amount and atmospheric
研究结果表明：在不同海拔高度和等值盐密esdd下，绝缘子的最低交流冰闪电压均随覆冰量的增加而呈指数规律降低；当覆冰量增加到一定程度后，最低交流冰闪电压随覆冰量增加而降低的趋势趋于饱和；不同绝缘子串的平均饱和覆冰量及闪络电压的覆冰量影响特征指数m均与绝缘子的盘径和伞距等因素有关；在海拔4000 5500m之间，不同等值盐密esdd和覆冰状态下，绝缘子的交流冰闪电压随海拔高度的增加(气压的降低)与p / p0呈乘幂关系降低，气压影响特征指数n与绝缘子类型、覆冰类型、覆冰表面状况等因素有关；当覆冰量和气压一定时，绝缘子的最低冰闪电压均随着等值盐密( esdd )或覆冰水电导率的增加而呈乘幂关系降低，并逐渐趋于饱和。
