电力变压器.第2部分:液浸变压器的温升

[中文适用范围]： 本部分 IEC 60076 适用于油浸式变压器，根据冷却方法识别电力变压器，定义温升限值，并提供温升试验方法。 [外文原描述]： IEC 60076-2:2011 applies to liquid-immersed transformers, identifies power transformers according to their cooling methods, defines temperature rise limits and gives the methods for temperature rise tests. This new edition includes the following significant technical changes with respect to the previous edition: - the winding hot-spot temperature rise limit was introduced among the prescriptions; - the procedures for the temperature rise test were improved in relation to the new thermal requirements; - five informative annexes were added in order to facilitate the implementation of this standard.
