PRIMARY WINDING OF TRANSFORMER FOR METER

摘要

PROBLEM TO BE SOLVED: To provide a primary winding of a transformer for a meter, which can be made uniform in the distribution of voltage between layers from the inner peripheral part of a spool to the outer peripheral part of the spool. SOLUTION: A multitude of winding layers W1 to Wn are wound on the outer periphery of a spool B in a state that insulating layers L1 to Ln-1 are made to interpose between the winding layers. The numbers of turns of all the layers M1 to Mn are made roughly equal. The layer Wn located at the position most apart from the spool B is evenly wound in the axis direction of wounding of a winding. The layers W1 to Wn-1 , which are positioned inside of the layer Wn , are divided into winding parts W1a to Wna , and winding parts W1b to Wnb and these winding parts are respectively arranged on both end sides in the axis direction of winding of the winding.
