<p>PURPOSE:To decrease a stray loss due to a leakage flux and to enable manufacturing a large capacity transformer easily by dividing each winding of a plurality of a high voltage and a low voltage into a corresponding wiring unit, disposing aparting above and below and by disposing a magnetic shielding body between each winding unit. CONSTITUTION:On an iron core leg 5 two each low voltage windings 3,4 aparting above and below with a determined dimension and indepedently are at innermost side and a high voltage winding 2 is disposed at the outside. And together with dividing a winding 2 into a same number as windings 3,4, forming winding units 2a,2b to be used in parallel, aparting above and below so as to face against to windings 3,4 and a magnetic shielding body 10 consisting of a same laminated body as a leg 5 is disposed between these above and below sets. The shielding body 10 acts as an electro- magnetic shielding body at a balanced load time and at an unbalanced load time a leakage flux from above and below each winding is flown through independent magnetic circuit passing the shielding body 10 respectively to eliminate an interference between above and below mutually. In this manner a transformer of a large capacity can be manufactured easily.</p> |
