标准摘要
[中文适用范围]： IEC 60060-1:2025 适用于： - 直流耐压试验； - 交流耐压试验； - 冲击耐压试验； - 上述组合的耐压试验。 本文件适用于最高设备电压 Um 高于 1.0 kV（交流）和 1.5 kV（直流）设备的试验。 本第四版取消并取代了 2010 年发布的第三版，属于技术性修订。相较于前一版，本版包含以下重要技术变更： - 对总体结构及文本进行了更新与优化，以提升标准的易用性，尤其是关于组合电压和复合试验电压的条款； - 对于 Um > 800 kV 的情况，将雷电冲击电压波前时间的正公差放宽至 100%（即 2.4 µs）； - 引入开关冲击电压的波前时间定义，类似雷电冲击电压，并据此将标准开关冲击电压定义为 170/2500 µs； - 根据 Um 的不同调整了关于降水的要求； - 新增附录 C《基于图形波形的手动计算程序》； - 附录 D《雷电冲击电压参数评估软件实施指南》中不再提供具体软件示例； - 删除了关于引入冲击电压系数以评估带过冲冲击的背景说明相关附录； - 新增资料性附录 F，对开关冲击电压波前时间的新定义进行了说明。 注 1：为获得可重复且具有意义的试验结果，可能需要采用替代试验程序。具体试验程序的选择由相关技术委员会审议决定。 注 2：对于 Um 高于 800 kV 的情况，部分规定的程序、公差及不确定度可能难以实现。 [外文原描述]： IEC 60060-1:2025 is applicable to: - dielectric tests with direct voltage; - dielectric tests with alternating voltage; - dielectric tests with impulse voltage; - dielectric tests with combinations of the above. This document is applicable to tests on equipment having its highest voltage for equipment Um above 1,0 kV AC and 1,5 kV DC. This fourth edition cancels and replaces the third edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - The general layout and text have been updated and improved to make the standard easier to use, particularly the clauses for combined and composite test voltages. - The positive tolerance of the front time of lightning impulse voltage has been extended for Um > 800 kV to 100 % (= 2,4 µs). - For switching impulse voltage, a front time has been introduced, similar to lightning impulse voltage and with the new front time the standard switching impulse is defined as 170/2 500 µs. - The requirements for precipitations have been adjusted depending on Um. - A new Annex C, "Procedure for manual calculation from graphical waveforms" has been incorporated. - No examples of software have been given in Annex D, "Guidance for implementing software for evaluation of lightning impulse voltage parameters". - The annex relating to the "Background to the introduction of the test voltage factor for evaluation of impulses with overshoot" has been deleted. - A new informative Annex F, "New definition of the front time of switching impulse voltage" has been incorporated. NOTE 1 Alternative test procedures can be required to obtain reproducible and significant results. The choice of a suitable test procedure is considered by the relevant Technical Committee. NOTE 2 For voltages Um above 800 kV it is possible that some specified procedures, tolerances and uncertainties will not be achievable.
