高压绝缘子无线电干扰试验

[中文适用范围]： 本国际标准规定了在实验室中对清洁干燥绝缘子进行无线电干扰（RI）测试的程序，测试频率为0.5MHz或1MHz，或在0.5MHz至2MHz之间的其他频率。 本文件适用于额定电压大于1000V的交流或直流架空电力线和架空牵引线路用绝缘子。 在实际使用中，绝缘子的RI特性可能会受到环境条件的影响，特别是降雨和其他湿度以及污染。认为指定可重复的测试条件来模拟一系列环境条件是不可行的。因此，本文件仅规定了对清洁干燥绝缘子的测试。 注：包括污染在内的绝缘子表面条件的影响见CISPR 18-2:2017第6.3条。 [外文原描述]： IEC 60437:2023 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60437:2023 edition 3.0 and the previous IEC 60437:1997 edition 2.0. Furthermore, comments from IEC TC 36 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 60437:2023 specifies the procedure for a radio interference (RI) test carried out in a laboratory on clean and dry insulators at a frequency of 0,5 MHz or 1 MHz or, alternatively, at other frequencies between 0,5 MHz and 2 MHz. This document applies to insulators for use on AC or DC overhead power lines and overhead traction lines with a nominal voltage greater than 1 000 V. This third edition cancels and replaces the second edition published in 1997. This third edition cancels and replaces the second edition published in 1997. This edition includes the following significant technical changes with respect to the previous edition: a) Composite station post and composite hollow core station post insulators have been included; b) All paragraphs of Samples test were actualized; c) Sample test fast procedure was introduced.
