首先要弄清楚一点:9 [8 f4 W2 t+ L& S& c( t# b0 L! n
LZ测的是高温绝缘电阻,这个应该是没有问题的。& t) c2 w4 S! A1 v; K
高温绝缘电阻怎样测呢?
# Y$ S" ~# F: e8 sC 3005-1993有如下规定:, `1 e8 Q; a" s, Z/ I5 j
9.2 Insulation resistance at high temperature: Sample a suitable length of a core specimen from the product, immerse it in water at a spesified temperature +-1 C, until the temperature of the insulation is stabilized, and then measure the insulation resistance by the method of 9.1. Do not carry out temperature conversion.
0 o6 I5 X& n; s9 J- m# \' c0 z这段话中,抽取的是CORE SPECIMEN,参考国标70C绝缘电阻测试方法,这指的应该是芯线。
5 e+ W h! A5 M" l5 x4 n* x8 @最好是翻阅日文版C 3005上面规定的很清楚。不过我不懂日文---& _3 |% @5 X9 Y9 h: r9 X5 G/ Z
