判断干式变压器线圈内金属导线材质的方法
摘要：
本发明提供了一种判断环氧树脂浇注干式变压器线圈内金属导线材质的方法，通过将待检测线圈的外形尺寸和质量数据与铜导体环氧树脂浇注干式变压器线圈的标准数据进行比较，若待检测线圈的长度和/或宽度大于标准数据中的长度和/或宽度8～10％、且质量比标准数据中的质量低15～25％，则判断该待检测线圈内的金属导线材质为铝。通过本发明，能够方便快捷地判定环氧树脂浇注干式变压器线圈为铜导体或铝导体的方法。
摘要（英）：

The invention provides a method for judging a material of a metal conductor in an epoxy resin-cast dry type transformer coil. By comparing the appearance size and quality data of a to-be-detected coil with standard data of a copper conductor epoxy resin-cast dry type transformer coil, and if the length and/or width of the to-be-detected coil is larger than the length and/or width in the standard data by 8-10% and the quality data are lower than that in the standard data by 15-25%, the material of the metal conductor in the to-be-detected coil can be judged to be aluminum. Through adopting the method, the material of the epoxy resin-cast dry type transformer coil can be conveniently and fast judged as a copper conductor or an aluminum conductor.
