标准摘要
[中文适用范围]： 本文件规定了电缆及其附件进行耐受雷电和开关冲击试验以及耐受叠加冲击试验的程序。 本文件仅适用于试验方法的执行，与选择要指定的试验水平的问题无关。电缆及其附件要使用的系统相关电压在IEC 60183或相关产品标准中给出。 本文件规定了以下要求： - 试验装置的特性和状态以及耐受试验和超过耐受水平的试验共有的程序部分； - 进行耐受雷电和开关冲击试验以及叠加冲击试验的程序； - 进行超过耐受水平的试验的程序，该试验用于研究目的。 [外文原描述]： IEC 60230:2018+A1:2021 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.
