标准范围

IEC 60230:2018定义了对电缆及其附件进行耐雷电和开关冲击试验以及耐叠加冲击试验的程序。本文件仅适用于执行此类测试的方法，与选择待指定测试级别的问题无关。IEC 60183或相关产品标准中给出了与使用电缆和附件的系统相关的电压。本文件规定了以下要求:-测试装置的特性和状态，以及程序中为承受测试和高于承受水平的测试而常见的那些部分；-进行耐雷、开关冲击试验和叠加冲击试验的程序；-为研究目的进行高于承受水平的测试的程序。这第二版取消并取代了1966年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)标准的结构考虑了IEC标准的现行风格；b)本文件不再是“建议”，而是“国际标准”；c)测试安装不再仅与气压和充油电缆相关；d)包括开关冲击电压和叠加冲击电压测试；e)对于测量系统，增加了对IEC 60060-2的参考。对球间隙法的引用已移至附录B。

IEC 60230:2018 defines the procedure for carrying out withstand lightning and switching impulse tests and withstand superimposed impulse test on cables and their accessories.
This document applies solely to the methods of carrying out the tests as such, independently of the problem of selecting the test levels to be specified. The voltages pertaining to the system on which cables and accessories are to be used are given in IEC 60183 or in the relevant product standard.
This document specifies the following requirements:
- the characteristics and state of the test installation and those parts of the procedure which are common to withstand tests and tests above the withstand level;
- the procedure for carrying out withstand lightning, switching impulse tests and superimposed impulse test;
- the procedure for carrying out tests above the withstand level which is intended for research purposes.
This second edition cancels and replaces the first edition published in 1966. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the structure of the standard takes into account the current style of IEC standards;
b) this document is no longer a “Recommendation” but an “International Standard”;
c) the test installation is no longer related to gas-pressure and oil-filled cables only;
d) switching-impulse voltage and superimposed impulse voltage tests have been included;
e) for the measuring system the reference to IEC 60060-2 has been added. The reference to the sphere gap method has been moved to Annex B.
