| 摘要 |
<p>The present invention relates to a power transformer/inductor comprising at least one winding. The windings are designed by means of a high voltage cable (10), comprising an electric conductor, and around the conductor there is arranged a first semiconducting layer (14), around the first semiconducting layer (14) there is arranged an insulating layer (16) and around the insulating layer (16) there is arranged a second semiconducting layer (18). The second semiconducting layer (18) is directly earthed at both ends of each winding (221, 222) and furthermore at least at two points per turn of every winding (221, 222), whereby one or several points are indirectly earthed.</p> |
