这个很难有个标准答案，因为里面有很多部品，每个部品都有不同的温度要求,一般是关键点,或者关键零部件需要做温升。作者: 日夏清 时间: 2011-12-18 10:09

CL11.3
The temperature rise of electrical insulation, other than that of windings, is determined on the
surface of the insulation at places where failure could cause
– a short circuit;
– contact between live parts and accessible metal parts;
– bridging of insulation;
– a reduction of clearances or creepage distances below the values specified in clause 29.
