电绝缘.耐热性评定和设计

[中文适用范围]： 该国际标准现在区分电气绝缘系统和电气绝缘材料的耐热等级。它建立了评估电绝缘材料 (EIM) 或电绝缘系统 (EIS) 耐热性的标准。它还建立了分配耐热等级的程序。本标准适用于热因素是主要老化因素的情况。注：与 EIS 中的使用相关的耐热等级并未分配给 EIM。 [外文原描述]： IEC 60085:2007 now distinguishes between thermal classes for electrical insulation systems and electrical insulating materials. It establishes the criteria for evaluating the thermal endurance of either electrical insulating materials (EIM) or electrical insulation systems (EIS). It also establishes the procedure for assigning thermal classes. This standard is applicable where the thermal factor is the dominant ageing factor. The major technical changes with regard to the previous edition concern the fact that this edition is an amalgamation of the third edition of this standard together with IEC 62114:2001.
