标准摘要
[中文适用范围]： IEC 61857 的这一部分提供了确定用于评估拟议电气绝缘系统 (EIS) 的适当测试方法的指南。一些标准用于 EIS@ 的评估和分类，而其他标准则确定了评估拟议或已建立的 EIS 的单因素或多因素应力的适当方法。本技术报告适用于 IEC 标准的各种工作电压的电工产品中使用的现有或拟议的 EIS。该报告注重根据施工和预期运行条件选择适当的标准。 [外文原描述]： IEC TR 61857-2:2015(E) gives guidelines to identify the appropriate test method to be used for the evaluation of a proposed Electrical Insulation System (EIS). Some of the standards are for evaluation and classification of the EIS, while other standards identify the appropriate method to evaluate single or multi-factor stresses of a proposed or of an established EIS. This Technical Report is applicable to existing or proposed EIS used in electrotechnical products across a wide range of operating voltages of IEC Standards. The report takes care to select the appropriate standard based on construction and intended operating conditions.
