Description
本発明は、発電機、モータなどの回転電機に関する。
The present invention relates to a rotating electrical machine such as a generator or a motor. *
これまで、発電機、モータなどの回転電機において、固定子および回転子のコイルを形成する銅系導体材料の接続方法に導体材料を溶かし込むアーク溶接、TIG溶接などの溶融溶接を用いる場合、導体材料の溶接欠陥を防止するために、導体材料に酸素含有量の少ない銅を用いていた(下記特許文献)。
Conventionally, in a rotating electrical machine such as a generator or a motor, when using fusion welding such as arc welding or TIG welding for melting a conductor material in a connection method of copper-based conductor material forming a stator and a rotor coil, In order to prevent welding defects in the material, copper having a low oxygen content was used as the conductor material (the following patent document).
従来の発電機、モータなどの回転電機において、固定子及び回転子のコイルを構成する導体材料に酸素含有量が多く亜酸化銅粒子を含む銅を用いた場合、その接続にアーク溶接、TIG溶接などの溶融溶接を適用すると溶接欠陥が発生しやすい。また、溶融溶接による溶接欠陥を防止するために固定子及び回転子のコイルの導体材料に酸素含有量が少なく亜酸化銅粒子を含まない銅を用いた場合、焼鈍状態では、亜酸化銅粒子を含む銅に比べて定常クリープ速度が速くてクリープ変形しやすい。また、導体材料に亜酸化銅粒子を含んでいても、微量の硫黄(S)を含んでいるので、この硫黄が結晶粒界に偏析してクリープ強度を低くしている。このためコイルが運転寿命期間中にクリープ変形あるいはクリープ破断しないよう構造設計する必要があり、その結果、コイルの支持構造が複雑になる。
In conventional rotating electrical machines such as generators and motors, when copper containing a large amount of oxygen and containing cuprous oxide particles is used as the conductor material constituting the stator and rotor coils, arc welding and TIG welding are used for the connection. When applying fusion welding such as, welding defects are likely to occur. In addition, in order to prevent welding defects due to fusion welding, when copper having a low oxygen content and not containing cuprous oxide particles is used as the conductor material of the stator and rotor coils, cuprous oxide particles are used in the annealed state. Compared to copper, the steady-state creep rate is high and creep deformation tends to occur. Moreover, even if the conductor material contains cuprous oxide particles, since it contains a trace amount of sulfur (S), this sulfur segregates at the crystal grain boundary to lower the creep strength. For this reason, it is necessary to design the coil so that it does not undergo creep deformation or creep rupture during the operating life, resulting in a complicated coil support structure.
本発明の目的は、コイルの導体材料に酸素含有量が多く亜酸化銅粒子を含む銅を用いた場合でも、接続部に欠陥が発生し難いコイル導体材料を有する回転電機を提供することにある。

本発明の導体材料は、マグネシウム添加により硫化物を形成して粒界に偏析する硫黄(S)が少ないため、引張応力が作用しても粒界のボイド形成が抑制されるので室温から300℃でのクリープ強度が高い。
Since the conductor material of the present invention has a small amount of sulfur (S) segregated at the grain boundary by forming a sulfide by adding magnesium, void formation at the grain boundary is suppressed even when a tensile stress is applied. The creep strength at is high.
また、本発明の導体材料をリン銅ロウでロウ付けした接続構造は、導体材料の接続にリン銅ロウを用いるので、フラックスを必要としない。このため、フラックス除去の工程が省略できる。また、リン銅ロウによって導体材料を接続する場合には、導体材料の接続構造にリン銅ロウを設置(置きロウ)または供給(挿しロウ)し、アセチレンガスバーナ、プロパンガスバーナ、誘導コイル、TIGトーチなどによって、700~850℃の温度で10~200秒加熱して、リン銅ロウを溶かすが、母材への入熱が少ないため母材の局部的溶融・凝固が起きないので割れる懸念が無い。
Also, the connection structure in which the conductor material of the present invention is brazed with phosphorous copper braze uses phosphorous copper braze for the connection of the conductor material, and therefore does not require flux.

以下に、導体材料に含まれている元素の効果と、その組成(単位は質量%)の範囲の限定理由について述べる。
Below, the effect of the elements contained in the conductor material and the reasons for limiting the range of the composition (unit: mass%) will be described.
酸素(O)は、その素材製造工程から不可避的に0.0001%以上含まれる。また酸素は導体材料の中に亜酸化銅粒子を生成して定常クリープ(二次クリープ)速度を遅くすることにより破断寿命を増してクリープ強度を高めるので0.0001%以上添加する。しかし、酸素は導体材料の導電率を低下させる元素である。このため、酸素の範囲は0.0001~0.0500%である。
Oxygen (O) is inevitably contained in the material manufacturing process by 0.0001% or more. Oxygen is added in an amount of 0.0001% or more because it produces cuprous oxide particles in the conductor material and slows the steady creep (secondary creep) rate to increase the fracture life and increase the creep strength. However, oxygen is an element that decreases the conductivity of the conductor material. For this reason, the range of oxygen is 0.0001 to 0.0500%.
銀(Ag)は、その素材製造工程から不可避的に0.0001%以上含まれる。また銀は導体材料の銅に固溶して定常クリープ(二次クリープ)速度を遅くすることにより破断寿命を増してクリープ強度を高めるので0.0001%以上添加する。しかし、銀は導体材料の導電率を低下させる元素である。このため、銀の範囲は0.0001~0.5000%とする。
Silver (Ag) is unavoidably contained in the material manufacturing process by 0.0001% or more. Silver is dissolved in copper as a conductor material and slows the steady creep (secondary creep) speed to increase the fracture life and increase the creep strength, so 0.0001% or more is added. However, silver is an element that lowers the conductivity of the conductor material. For this reason, the range of silver is made 0.0001 to 0.5000%.
マグネシウム(Mg)は、導体材料の硫黄(S)と結合して硫化物を生成して粒界に偏析する硫黄濃度を低めて導体材料の粒界での結合力を増すことによりクリープ強度を高める元素であり、0.0001%以上必要である。しかし、0.0200%を超えと導体材料の導電率を低下させる。このため、マグネシウムの範囲は0.0001~0.0200%とする。
Magnesium (Mg) increases the creep strength by combining the sulfur (S) of the conductor material to form a sulfide and lowering the sulfur concentration segregated at the grain boundary to increase the bond strength at the grain boundary of the conductor material. It is an element, and 0.0001% or more is necessary. However, if it exceeds 0.0200%, the conductivity of the conductor material is lowered. Therefore, the magnesium range is 0.0001 to 0.0200%.
本発明の導体材料をリン銅ロウでロウ付けした接続構造を使用している発電機、モータなどの回転電機はクリープ強度が高く、母材の割れなどの欠陥が無いので、接続部の信頼性が高いという効果がある。
