高压交流断路器标准的主要差异分析

Analysis of Major Differences in Standards for High-voltage Alternating-current Circuit-breakers

本文主要对GB/T 1984—2014与IEC 62271-100:2021的差异进行分析,主要针对文本差异和基本技术参量差异两个方面,其中文本差异主要分析了适用范围和规范性引用文件、使用条件以及术语和定义;基本技术参量差异主要分析了额定绝缘水平、温升限值、TRV参数以及试验参量的容差。通过以上几个方面的分析,加深对标准理解和规范检测认证。

This paper mainly analyzes the main differences between the existing national standard GB/T 1984-2014 and IEC 62271-100:2021,focusing on the differences in text and basic technical parameters.The textual differences are analyzed in terms of scope,normative references and service conditions.The basic technical parameters differences are analyzed in terms of rated insulation level,limits of temperature,TRV parameters and the tolerance on test quantities.Through the analysis of the above aspects,the paper aims to deepen the understanding of the standards and regulate testing and certification.
