耐圧をもつ絶縁材が必要であった。Conventional typical wire rods for superconducting magnets have used metallic superconducting materials. However, since such superconducting materials have low critical temperatures,
Since liquid helium must be used as a cooling means, and liquid helium and gas helium have low breakdown voltages, superconducting magnet wires require insulating materials with extremely high breakdown voltages exceeding 500V.

めにも、上述した高耐圧絶縁が必要であった。In addition, since the ratio and heat of the components of the superconducting magnet, including the helium mentioned above, are small, the propagation speed of the normal conductive part when the superconducting material undergoes a normal conduction transition (quench) is faster and faster. This caused the accidental generation of high voltage. In order to prevent the magnet from being destroyed (arc generation and insulation failure) due to the high voltage generated during this quenching, the above-mentioned high withstand voltage insulation was necessary.

In the Ba-Cu-0 system, a critical temperature of 90°C has been obtained.

Ｖと次の関係にある。If a superconducting magnet wire made of this material is used at a temperature of 1 in 77, which corresponds to the boiling point of liquid nitrogen under atmospheric pressure, the maximum value VI11 of the voltage across the coil when the magnet is quenched is: It has the following relationship with the propagation velocity V of normal conduction.

1 0-'° m/see, and compared with To at 4.2K (the boiling point of liquid helium under atmospheric pressure), it is 500
It will be 1/2 the time. In other words, the voltage across the coil is (

は、５００ｖを超える値にまで確保する必要がない。On the other hand, nitrogen as a refrigerant has a higher dielectric strength voltage than helium, whether in liquid or gas state, and the dielectric strength required for the insulation coating of superconducting magnet wire exceeds 500V. There is no need to secure it.
また、冷媒として液体ヘリウムを用いるとしても、コイ
ル両端における最大電圧が低いので、５００ｖを超える
耐圧を必要としない。Further, even if liquid helium is used as the refrigerant, the maximum voltage at both ends of the coil is low, so a withstand voltage exceeding 500V is not required.
このように、この発明では、臨界温度の高い超電導材料

縁材が不要となる。In this way, since the present invention uses a superconducting material with a high critical temperature, it is possible to use a liquid or gas such as neon or nitrogen, which has a higher dielectric strength than helium, and therefore can achieve a high dielectric strength exceeding 500V. This eliminates the need for insulating materials with

速度を遅くすることができ、それによってコイルの発生
電圧を低くすることができる。Further, as described above, since a superconducting material with a high critical temperature is used, and therefore the operating temperature can be increased, the propagation speed of normal conduction can be slowed down, and thereby the voltage generated in the coil can be lowered.
このことからも、絶縁材に対して高い耐圧が要求されな

Those containing glass fibers, Al2O, coatings,
etc. can be used.

である。The above-mentioned materials have low breakdown voltage as insulating materials, but can be made thin. Therefore, not only the cooling performance is improved, but also the size can be reduced, so that the bucking factor as a coil is improved, the current density is increased, and the obtained coil is made compact. In particular, improved cooling performance greatly contributes to the stability of the coil, making it difficult for quench to occur, and greatly improving the reliability of systems using magnets.
