Transformer type tie-plate for reduced stray loss and manufacturing method thereof

摘要

The present invention relates to a transformer tie plate for reducing stray loss generated in a tie plate by a leakage magnetic flux in a transformer in which a coil is wound on an iron core to reduce harmonics and unbalance generated in a power distribution system. And a manufacturing method thereof. A transformer tie plate according to an embodiment of the present invention includes an upper frame positioned at an upper portion of an iron core and fixing an upper portion of the iron core; A lower frame positioned below the iron core for fixing a lower portion of the iron core; And a vertical support vertically connecting the upper frame and the lower frame through a first support, a second support and a third support corresponding to the first leg, the second leg and the third leg, 2 support and the third support are formed with a central protrusion at the center to reduce stray loss by suppressing the leakage flux generated in the primary and secondary coils, .
