高压测试技术 第1部分：通用定义、要求和程序

[中文适用范围]： IEC 60060-1:2025 RLV 包含官方 IEC 国际标准及其红线版本。红线版本仅提供英文版，可让您快速轻松地比较官方 IEC 标准与其先前版本之间的所有变化。IEC 60060-1:2025 适用于：- 采用直流电压的介电试验；- 采用交流电压的介电试验；- 采用脉冲电压的介电试验；- 采用上述组合的介电试验。本文件适用于对设备最高电压 Um 高于 1.0 kV AC 和 1.5 kV DC 的设备进行测试。第四版取消并取代了 2010 年发布的第三版。此版本构成技术修订。此版本与上一版相比包括以下重大技术变化：- 总体布局和文本已更新和改进，以使标准更易于使用，特别是组合和复合测试电压的条款。 - 雷电冲击电压前沿时间的正公差已扩展至Um > 800 kV的100% (= 2.4 µs)。- 对于操作冲击电压，引入了与雷电冲击电压类似的前沿时间，并根据新的前沿时间将标准操作冲击定义为170/2 500 µs。- 已根据Um调整了对沉淀的要求。- 新增了附录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”中未提供任何软件示例。- 删除了关于“引入用于评估过冲脉冲的测试电压因子的背景”的附录。- 新增了参考性附录F“操作冲击电压前沿时间的新定义”。注1：可能需要采用其他测试程序才能获得可重复且有意义的结果。合适的测试程序的选择由相关技术委员会负责考虑。注 2：对于 800kV 以上的电压 Um，某些规定的程序、公差和不确定性可能无法实现。 [外文原描述]： IEC 60060-1:2025 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. 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.
