本文以江苏地区为调查区域,针对水泥厂、化工厂、煤粉场、农业污染等几类典型污染源的现场挂网绝缘子进行采样分析,分别得到不同污源绝缘子的盐、灰密、离子成分以及颗粒物粒径分布数据,结果表明,化工厂污源和煤粉厂污源所含的无机盐含量最多,水泥污染源污秽中所含难溶物最多;根据实测数据规律,NO3-可表征化工类污源,NH4+可表征农田类污源.对几类典型污源自然污秽绝缘子,进行了高电导率雾对闪络电压影响的试验,结果表明,化工、农田和电厂类自然污秽绝缘子闪络电压均随雾水电导率升高而降低,煤粉类污秽闪络电压会随雾水电导率升高呈现饱和趋势.

众所周知,当电缆在恶劣环境下运行时,容易造成绝缘性能的劣化,而电缆附件(包括中间接头和终端)是电缆线路的薄弱环节,其绝缘屏蔽口处的电应力集中容易发生故障。有研究表明,对于高压电缆线路运行故障,约80%以上都是由电缆附件引起的。因此局部放电试验能够有效检测并定位电缆附件中的潜在绝缘缺陷,是电缆状态评估工作的重要组成部分.本文从电缆附件的制作过程和安装工艺,分析了电缆附件发生局部放电的原因,其次详细介
