电气绝缘系统（EIS）.液体和固体组合部件的热评估.第2部分:简化试验

[中文适用范围]： 本文档是 IEC 62332 系列的技术规范，适用于包含固体和液体成分且热应力为主要老化因素的电气绝缘系统（EIS），不受电压等级限制。本部分规定了用于热评估和资格认证的密封管测试程序。该程序还提供了一种为同时使用固体和液体成分的材料分配热分类的方法。该程序描述了一种比较老化方法，即由kraft纸和矿物油组成的参考系统与任何组合的固体和绝缘液体候选系统进行比较。本部分的测试程序专门适用于浸油变压器绝缘系统。类似的程序也应适用于其他具有液体和固体成分组合的电气设备，如套管、电缆或电容器，但这将在获得使用该技术规范的经验后作为补充部分添加。 [外文原描述]： IEC TS 62332-2:2014 is applicable to EIS containing solid and liquid components where the thermal stress is the dominant ageing factor, without restriction to voltage class. This part specifies a sealed tube test procedure for the thermal evaluation and qualification of electrical insulation systems (EIS). One aspect of this procedure is to also provide a method to assign thermal classifications to materials used in EIS where solid and liquid components are both used. This procedure describes a comparative ageing method whereby a reference system composed of kraft paper and mineral oil is compared to a candidate system of any combination of solid and insulating liquid. The test procedures in this part are specifically applicable to liquid immersed transformer insulation systems.
