高压电力设备外绝缘的耐污秽设计研究

摘要

The process and feature of flashover of h.v.power appliance under pollution is described.A proper rnexternal insulation design against pollution is introduced.It is demonstrated by practice that the most economrnic and essential approach to avoid flashover due to pollution and to simplify anti-pollution maintenance is reasrnonable selection of shed profile for external insulation.The significance of this study is pointed out.%介绍了高压电力设备外绝缘发生污秽闪络的过程和特点。重点论述了合理进行高压rn电力设备外绝缘的污秽设计,结合实际阐明了科学设计(选取)外绝缘伞形结构是解决污闪问题rn及减轻防污工作的最主要的也是最经济的方法。最后指出了这些研究的重要意义。
