TRANSFORMER WITH A UNIT CORE

摘要

PURPOSE: A transformer is provided to mold a core as a unit core of a rectangular shape and to reduce the entire volume by rolling low pressure and high pressure coils on arms of the unit core. CONSTITUTION: A unit core(100) of a rectangular shape is formed by cut a thin plate as establishment dimension. One core body(200) is formed in order to maintain the unit core of the rectangular shape as triangle shape with adjacent unit cores. Low pressure and high pressure coils(300) are rolled on a core arm part(120) of the unit core of the rectangular shape. A cut opening part(500) is formed by cutting the core arm part of the unit core of the rectangular shape at a constant interval. Coils in which the low pressure and high pressure coils are rolled are inserted in a separate line through the cut opening part.
