标准摘要
[中文适用范围]： IEC TS 63263:2025描述了一种测试方法，用于在高温条件下评估绕组线在高频电压脉冲（伴随局部放电）作用下的寿命。该方法仅适用于在特定样品制备和测试环境下的比较性评估。该文件的比较性质在于，局部放电下的寿命受样品制备和测试条件中大量影响因素的影响，这些因素至今尚未能全部深入研究。本文件适用于圆形和矩形磁性绕组线。 [外文原描述]： IEC TS 63263:2025 describes a test method for evaluating the lifetime of winding wires under electrical high frequency voltage impulses (with partial discharges) at elevated temperatures. This method is only applicable as a comparative examination under a given sample preparation and testing environment. The comparative nature of this document lies in the fact that the lifetime under partial discharges depends on a large number of influencing factors in the sample preparation and test conditions which could not all be thoroughly investigated so far. This document applies to round and rectangular magnet wires.
