标准范围

IEC 62772:2023作为IEC 62772:2023 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 62772:2023适用于由树脂浸渍纤维制成的承重绝缘管（芯）、绝缘填充材料（固体、液体、气体加压或非加压）、由聚合材料（例如硅树脂或乙烯丙烯）制成的外壳（绝缘管外部）以及绝缘管末端的固定装置。本标准中定义的复合空心站柱绝缘子用于室外和室内环境下的变电站，额定交流电压大于1 000 V，频率不大于100 Hz，或用于额定电压大于1 500 V DC的直流系统。本文件的目的是:-定义所使用的术语；-规定测试方法；-规定验收标准。

IEC 62772:2023 is available as IEC 62772:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62772:2023 applies to composite hollow core station post insulators consisting of a load-bearing insulating tube (core) made of resin impregnated fibres, insulating filler material (solid, liquid, gaseous – pressurized or unpressurized), a housing (outside the insulating tube) made of polymeric material (for example silicone or ethylene-propylene) and fixing devices at the ends of the insulating tube. Composite hollow core station post insulators as defined in this standard are intended for general use in substations in both, outdoor and indoor environments, operating with a rated AC voltage greater than 1 000 V and a frequency not greater than 100 Hz or for use in direct current systems with a rated voltage greater than 1 500 V DC. The object of this document is:
- to define the terms used;
- to specify test methods;
- to specify acceptance criteria.
