摘要
分析了大气尘微粒运动的机理 ,并通过对其单位时间内沉积到单元垂直表面及单元水平表面上微粒量的分析计算 ,表明了对于树脂浇注绝缘质量优良和结构设计合理的高电压 (35～ 110kV)干式电力变压器在二级空气质量和适当清理周期的条件下运行时可以不考虑积尘对绝缘性能的影响。
The mechanism of the movement of atmospheric dust particles is unalyzed. Based on the study of the quantity of dust particles precipitated on the unit vertical and horizontal surfaces in unit time, it is indicated that for good quality cast resin insulation and reasonable construction design of high voltage (35～110kV) dry type power transformer operated in the second grade air quality condition and with suitable cleaning period the effect of accumulative dust on insulation performance could be neglected.
