本文采用X-射线粉末衍射仪、X-射线能谱仪、电感耦合等离子体发射光谱仪及离子色谱仪对广州市区及郊区化工厂、焦化厂、发电厂、钢铁厂、农田等五种典型环境中的输电线路绝缘子污秽的化学成分进行了定性和定量分析。这些区域绝缘子污秽主要由C、SiO2、CaSO4、硅铝酸盐、氯化物(KCl、NaCl、MgCl2等)、Fe3O4等组成。污秽中的炭黑的存在提高了污秽的电导率,对污闪事故的贡献不容忽视。化工厂和焦化厂

本文采用X-射线粉末衍射仪、X-射线能谱仪、电感耦合等离子体发射光谱仪及离子色谱仪对广州市区及郊区化工厂、焦化厂、发电厂、钢铁厂、农田等五种典型环境中的输电线路绝缘子污秽的化学成分进行了定性和定量分析。这些区域绝缘子污秽主要由C、SiO2、CaSO4、硅铝酸盐、氯化物(KCl、NaCl、MgCl2等)、Fe3O4等组成。污秽中的炭黑的存在提高了污秽的电导率,对污闪事故的贡献不容忽视。化工厂和焦化厂附近绝缘子污秽一价盐含量较高,有较大的污闪风险,钢铁厂和发电厂绝缘子污秽一价盐含量很低。这些研究结果对广州地区输电线路绝缘子的选型、运行和维护,防污措施的制订,绝缘子污闪事故的原因分析,具有重要的参考意义。
