高压用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]： 本技术规范适用于由陶瓷或玻璃制成的承载绝缘固体或空心芯、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部配件组成的交流和直流应用的混合绝缘子。本技术规范涵盖的混合绝缘子适用于用作悬垂/张力线路绝缘子、线路支柱绝缘子、站支柱绝缘子和设备的空心芯绝缘子。本技术规范的目的是：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，附录B）、增强伞、伞延伸器和雨水偏转器不在本技术规范的范围内。本技术规范不包括针对特定操作条件选择绝缘子的要求。 [外文原描述]： IEC TS 62896:2015(E) applies to hybrid insulators for a.c. and d.c. applications 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 technical specification are intended for use as suspension/tension line insulators, line post insulators, station post insulators and hollow core insulators for apparatus. The object of this technical specification is to: - define the terms used; - prescribe test methods; - prescribe acceptance criteria. Silicone or other functional coatings (CIGRE Technical Brochure No. 478, Appendix B), booster sheds, shed extenders and rain deflectors are not within the scope of this technical specification. This technical specification does not include requirements dealing with the choice of insulators for specific operating conditions.
