<p>PURPOSE:To make it possible to easily adjust the amount of leakage magnetic flux, by providing a magnetic leakage core of a tubular magnetic material with a high electric resistance between inner and outer windings wound on the core leg of a transformer. CONSTITUTION:Several kinds of core are prepared which are different from each other in length L and thickness (t). Any desired core 4 is inserted between an inner winding 2 and an outer winding 3, thereby obtaining a predetermined leakage magnetic flux, that is, a predetermined inductive reactance. If the length L or thickness (t) of the core 4 is smaller than the distance between the inner and outer windings 2, 3, the periphery of the core 4 may be wrapped or laminated with an electrical insulator.</p> |
