although the ac flashover performance of a polluted insulator has been studied well, there is few study on the valid coefficient of creepage distance of different types of insulators.
国内外虽对交流污闪特性研究较多,但对不同型式绝缘子的有效爬电系数及电弧发展路径研究不多。
creepage distance - shortest path between two conductive parts, or between a conductive parts and the bunding surface of the equipment, measured along the surface of the insulation.
爬电距离–沿绝缘材料表面测量,两个导体部件之间或者一个导体部件与产品的绝缘外壳之间的最短距离。
calculation and numerical analysis from programming educesaccurate measurement of creepage distance in complicated structure, thereby strengthening the proficiency test ability.
爬电距离是安全试验和国内外水平测试的重要项目。
creepage distance is an important test item of safety test and international proficiency test.
爬电距离是安全试验和国内外水平测试的重要项目。
ac flashover voltage, voltage gradient along the leakage distance and the valid creepage distance of polluted insulators are related to its materials and configuration.
人工污秽绝缘子的闪络电压、污闪电压梯度和有效爬电系数均与其材质和型式有关。
the total creepage distance of an insulator shall be not less creepage distance requested by the pollution level for the site.
绝缘子总的爬距应等于或大于由该地区污秽等级所要求的爬距。
