| 摘 要： | 污秽对电力系统安全稳定运行影响极大,某些特殊环境条件下的漂尘污染对输变电设备外绝缘也会构成威胁。文章分析了发生电气设备外绝缘放电的原因,即在输变电设备外绝缘的背风侧积聚的漂尘遇到合适的气象条件,就会污染在输变电设备外绝缘背风侧的空气,并在空气中产生放电,危及运行安全。文中还提供了几个例证。

| Abstract: | Influence of pollution on safety and steady operation of power system is very serious,and floating dust pollution in some special ambient conditions can also form threat for external insulation of power transmission and transformation equipment. The paper analyzed the reason that occurs the external insulation discharge of electrical equipment.If floating dust can be gathered at the leeward side of external insulation of power transmission and transformation equipment under the suitable meteorology condition, the air discharge at the leeward side of external insulation of power transmission and transformation equipment can occur,which is dangerous for safety operation.Some illustrations are offered in the paper. |
