电气绝缘系统.热应力和电应力组合的短时评估

[中文适用范围]： 该技术规范适用于电气绝缘系统 (EIS)，规定了短时热和电气评估程序 • 适用于电源电压高达 1000 V（直流/交流/脉冲）的设备， • 使用绕线线圈模型；该模型可用于绕线应用，例如变压器、扼流器、镇流器、电抗器、铁氧体转换器等， • 在最低老化温度下的最小测试寿命为 1500 小时， • 适用于通常不经受环境影响的产品振动。该模型应包含最终产品的所有成分，以确定热老化条件下的化学相互作用。不允许修改，因为该老化程序旨在评估整个 EIS。 [外文原描述]： Applies to electrical insulation systems, specifies a short-time thermal and electrical evaluation procedure - applicable for devices with a supply voltage up to 1000 V (d.c./a.c./pulse), - using a wire-wound coil model; this model may be used for wire-wound applications, such as transformers, chokes, ballasts, reactors, ferrite converters, etc., - with minimum test life of 1500 h at the lowest ageing temperature, - for products that are not normally subjected to vibration. The model shall contain all components of the final product in order to determine chemical interaction under thermal ageing conditions. No modifications are allowed because this ageing program is designed to evaluate the entire EIS.
