摘要

比较了用新合成酯和旧合成酯midel7131浸渍的湿化电工板的电性能。对新合成酯和旧合成酯浸渍的电工板在0.5% ~ 6%的含水量范围内进行了损耗角切线作为基本电学性能的测试。所选的水分含量对应于全新变压器单元和符合更换条件的变压器的初始水分含量。通过研究，我们发现了浸渍的液体对湿性纤维素绝缘材料电性能的影响。

Comparison of Electrical Properties of Moistured Pressboard Impregnated with New and Used Synthetic Ester

The paper compares the electrical properties of moistened electrotechnical pressboard impregnated with factory-new and used synthetic ester MIDEL 7131. The tangent of the loss angle as the basic electrical properties of the electrotechnical pressboard impregnated with new and used synthetic ester was tested for four different moisture contents ranging from 0.5% by weight up to 6% by weight. The selected moisture contents correspond to the initial moisture contents of the brand new transformer units and of the transformers that are eligible for replacement. Thanks to the research, it was found out what influence the liquid we impregnate with has on the electrical properties of the moist cellulose insulation.
