交流 1000 V 和直流 1500 V 以上高压应用的交流和直流混合绝缘子 定义、试验方法和验收标准

[中文适用范围]： 本文件适用于交流和直流应用大于1000V AC和1500V DC的混合绝缘子，其由陶瓷或玻璃制成的承载绝缘固体或空心芯、由聚合物材料制成的外壳（定义几何形状，在绝缘芯外部）和永久连接到绝缘芯的端配件组成。本文件涵盖的混合绝缘子适用于悬式/张力长杆和帽针式绝缘子、线路柱式绝缘子、站柱式绝缘子和设备用空心绝缘子。本文件的目的是：•定义使用的术语；•规定测试方法；•规定验收标准。硅胶或其他功能涂层（CIGRE技术手册第478号）、增强伞裙、伞裙延伸器和雨偏转器不在本文件范围内。CIGRE B2.69于2021年6月发布了两份技术手册，TB 837和TB 838，涉及绝缘子防污涂层的实际应用和经验收集。本文件不包括针对特定运行条件选择绝缘子的要求。 [外文原描述]： IEC 62896:2024 applies to hybrid insulators for AC and DC applications greater than 1 000 V AC and 1 500 V DC consisting of a load-bearing insulating solid or hollow core consisting of ceramic or glass, a housing (defined geometry, outside the insulating core) made of polymeric material and end fittings permanently attached to the insulating core. Hybrid insulators covered by this document are intended for use as suspension/tension long rod and cap and pin type insulators, line post insulators, station post insulators and hollow core insulators for apparatus. The object of this document is to: - define the terms used; - prescribe test methods; - prescribe acceptance criteria This document does not include requirements dealing with the choice of insulators for specific operating conditions. This first edition cancels and replaces the IEC TS 62896 published in 2015. This edition includes the following significant technical changes with respect to the previous edition: - modifications of terms and definitions; - modifications of tests procedures included in IEC TR 62039 and IEC 62217 (Hydrophobicity transfer test); - harmonization of Table 1 (Tests to be carried out after design and type changes) with other product standards and IEC 62217.
