摘　　要：变压器固体绝缘状态信息的特征量受电压、温度、环境等因素影响,具有模糊性,无法准确选择和判断的特点。目前,国内外学者研究了多种变压器固体绝缘的判断方法,但均具有局限性。通过研究能够反映电力变压器固体绝缘部位的特征量,基于模糊数学理论,利用模糊综合评判法对固体绝缘进行综合诊断,建立了变压器固体绝缘状况的评估模型。实例结果验证了该方法的有效性与实用性。The information of transformer solid insulation state is fuzzy and unable to effectively judge.Therefore,an evaluation method of power transformer solid insulation state is proposed.In this paper,the characteristic quantities that can reflect the fault parts of power transformer solid insulation are studied,and the fault parts are comprehensively diagnosed by fuzzy comprehensive evaluation method,and the evaluation model of transformer solid insulation condition is established.The results show that the method is effective and practical.
