请教高手。bobbin-wound transformer 这种变压器是什么样子的，有没有图片给看一下或解释说明。

谢谢！

我的理解是变压器的BOBBIN是工字型BOBBIN.对于要做15天测试的变压器你可以看标准后面的要求,其中有一条只要是初级线圈在次级线圈上面,或次级线圈在初级上面,那么变压器就需要做15天测试.当然三层绝缘线除外....

A Bobbin Wound Transformer is a transformer that is designed with the coil wound on a coil form or bobbin. The core structure is then mounted to the bobbin. Bobbin wound transformers can be designed to operate from 60Hz, or line frequency, well into the MHz range.
