断面が矩形の磁性体を用いて形成される複数の鉄心と、
前記鉄心の外側に絶縁物たるボビンを設け、該ボビンを隔て前記鉄心に導体を巻回して内側導体及び外側導体を形成するコイルを複数有し、該コイルを一列に並べて配置する変圧器において、
両端に配置される前記コイルの双方には少なくとも１つの同一の鉄心が挿通され、
隣接する前記コイルの双方には少なくとも１つの同一の鉄心が挿通され、
両端のコイル内を挿通する最も外側の鉄心の幅を、内側の鉄心の幅に対して狭く形成し、
両端のコイル内を挿通する鉄心に前記ボビンを取り付け、前記内側導体及び前記外側導体を巻き回すことで、両端のコイルの外形を端部外方に張り出すよう形成することを特徴とする油入変圧器。 A plurality of iron cores formed using a magnetic body having a rectangular cross section;
In the transformer in which a bobbin that is an insulator is provided outside the iron core, a plurality of coils are formed by winding a conductor around the iron core with the bobbin interposed therebetween to form an inner conductor and an outer conductor, and the coils are arranged in a row.
At least one identical iron core is inserted through both of the coils arranged at both ends,
At least one identical iron core is inserted through both of the adjacent coils,
The width of the outermost core inserted through the coils at both ends is formed narrower than the width of the inner core,
Oil bobbin is characterized in that the bobbin is attached to an iron core that passes through the inside of the coils at both ends, and the outer and outer conductors are wound so that the outer shape of the coils at both ends is projected outward. Transformer. 前記変圧器は、前記コイルを２つ具備する単相変圧器であることを特徴とする請求項１記載の油入変圧器。   The oil-filled transformer according to claim 1, wherein the transformer is a single-phase transformer having two of the coils. 前記変圧器は、前記コイルを３つ具備する三相変圧器であることを特徴とする請求項１記載の油入変圧器。   The oil-filled transformer according to claim 1, wherein the transformer is a three-phase transformer having three coils.
