室内外用聚合物高压绝缘子.一般定义、试验方法和验收标准

[中文适用范围]： 该国际标准适用于绝缘体由一种或多种有机材料组成的聚合物绝缘子。本标准涵盖的聚合物绝缘子包括实心绝缘子和空心绝缘子。它们设计用于高压架空线路以及室内和室外设备。本标准的目的是：定义聚合物绝缘子使用的通用术语；规定聚合物绝缘子设计试验的通用试验方法；如有适用，规定验收或失效标准。这些试验、标准和推荐旨在确保在正常运行和环境影响下具有满意的寿命（见第 5 章）。本标准应仅与相关的产品标准结合使用。 [外文原描述]： IEC 62217:2012 is applicable to polymeric insulators whose insulating body consists of one or various organic materials. Polymeric insulators covered by this standard include both solid core and hollow insulators. They are intended for use on HV overhead lines and in indoor and outdoor equipment. The object of this standard is: - to define the common terms used for polymeric insulators; - to prescribe common test methods for design tests on polymeric insulators; - to prescribe acceptance or failure criteria, if applicable. These tests, criteria and recommendations are intended to ensure a satisfactory life-time under normal operating and environmental conditions. This standard shall only be applied in conjunction with the relevant product standard. This second edition cancels and replaces the first edition published in 2005. This edition constitutes a technical revision. This edition includes a significant technical change with respect to the previous edition. The first edition of IEC 62217 (2005) included two other alternative tracking and erosion tests (a 5 000 hour multi-stress test and a tracking wheel test) which were based on tests developed by CIGRE and utilities. These tests are no longer given as normative alternatives following the results of a study/questionnaire by TC 36 on the relative merits of all three tracking and erosion tests. The 5 000 hour multi-stress test and a tracking wheel test are described in IEC/TR 62730 (2012).
