标准摘要
[中文适用范围]: IEC/TS 60815-3是一项技术规范,适用于交流系统聚合物绝缘子的选择及其相关尺寸的确定,以用于高压系统的防污染。 IEC/TS 60815的这一部分给出了具体的指导原则和原则,以便对特定污染环境中给定绝缘体的可能行为做出明智的判断。本技术规范的内容基于CIGRE 33.13 TF 01文件[1],[2 ]1,对于那些希望更深入地研究污染条件下绝缘子性能的人来说,这构成了对本技术规范的有用补充。本技术规范不涉及雪或冰对污染绝缘子的影响。尽管 CIGRE [3] 处理了这个主题,但目前的知识非常有限,实践也过于多样化。本技术规范的目的是为用户提供一种方法,根据场地污染严重程度确定参考统一比爬电距离 (USCD) (SPS) 级,〜选择适当的剖面,〜对参考 USCD 应用海拔、绝缘体形状、尺寸和位置等的修正系数。 [外文原描述]: IEC/TS 60815-3:2008(E) is applicable to the selection of polymer insulators for a.c. systems, and the determination of their relevant dimensions, to be used in high voltage systems with respect to pollution. This part of IEC/TS 60815 gives specific guidelines and principles to arrive at an informed judgement on the probable behaviour of a given insulator in certain pollution environments.
