Description
したがって、本発明では、新材料に最適な焼鈍条件を選定し、従来のアモルファス合金を採用した変圧器よりも低損失な配電用アモルファス変圧器を提供することを目的とする。
Fe量aは80%少ないと鉄心材料として十分な飽和磁束密度が得られず、また、83%以上では熱安定性が低下し、安定したアモルファス合金薄帯が製造できなくなるためです。さらに、Fe量の50%以下をCo、Niの1種または2種で置換してもよく、高飽和磁束密度を得るためには置換量をCoは40%以下、Niは10%以下とするのが好ましい。
Si量bは、アモルファス形成能に寄与する元素で、飽和磁束密度を向上させるためには5%以下であることが好ましい。
B量cは、アモルファス形成能に最も寄与し、8%未満では熱安定性が低下してしまい、18%より多く添加してもアモルファス形成能などの改善効果は見られない。また、高飽和磁束密度のアモルファスの熱安定性を保つには12%以上であることが好ましい。
Cは,角形性および飽和磁束密度の向上に効果があり、C量dは0.01%未満ではほとんど効果がなく、3%より多くすると脆化と熱安定性が低下する。
また、Cr、Mo、Zr、Hf、Nbの1種以上の元素を0.01〜5%含んでも良く、不可避な不純物としてMn,S,P,Sn,Cu,Al,Tiから少なくとも1種以上の元素を0.50%以下を含有しても良い。
本発明の配電用アモルファス変圧器の実施例について、図面を用いて説明する。
