本発明は、超電導電力貯蔵装置（以下、ＳＭＥＳと略称
する。）に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a superconducting power storage device (hereinafter abbreviated as SMES).
ＳＭＥＳは、超電導コイルに永久電流を流して電力を磁

、第８図に示す如く空洞壁６に真空封止機能を持たせる
場合もある。SMES stores electric power in the form of magnetic field energy by passing a persistent current through a superconducting coil, and in order to support the huge electromagnetic force that normally acts on the coil, a toroidal structure is placed inside the rock 1 as shown in Figure 6. A cavity 2 is formed, and various devices including a superconducting coil are installed inside this cavity 2. In addition, since SMES uses a superconducting coil cooled to an extremely low temperature (usually about 4 ℃) using a coolant such as liquid helium, the superconducting coil 3 is sealed in a helium container 4 as shown in FIG. In order to reduce the heat intrusion into the helium container 3 as much as possible, the helium container 4 is installed inside the vacuum container 5 to provide a vacuum insulation effect from the surroundings. Note that, as shown in FIG. 8, the cavity wall 6 may be provided with a vacuum sealing function.
ところで、このようなＳＭＥＳでは、超電導コイル３を
封入したヘリウム容器４が真空容器５または空洞壁６内

かも超電導コイル３を冷却するための冷媒も大量に必要
とし、真空バウンダリとしての機能も考慮して製作しな
ければならないため、コスト高になるという問題があっ
た。By the way, in such an SMES, the helium container 4 containing the superconducting coil 3 is installed in a vacuum inside the vacuum container 5 or the cavity wall 6, so the helium container 4 needs to have a pressure-resistant structure that can withstand internal pressure. . However, if the helium container 4 is made to have a pressure-resistant structure, it will become a thick-walled horizontal body, and it will also require a large amount of refrigerant to cool the superconducting coil 3, and the function as a vacuum boundary must be taken into account when manufacturing. There was a problem of high cost.
本発明は、このような問題点に鑑みてなされたもので、
構成が簡単でコストの低減を図ることができる超電導電

。In order to solve the above problems, the present invention provides a superconducting storage device in which a superconducting coil is installed in a cavity formed in a rock, and a persistent current is passed through the coil to store electric power. It is characterized by having a flow path.
本発明では、超電導コイル内に冷媒流路を設けることに
より、超電導コイルを冷媒流路を流通する冷媒によって
極低温に冷却できるため、ヘリウム容器が不要となる。In the present invention, by providing a refrigerant flow path within the superconducting coil, the superconducting coil can be cooled to an extremely low temperature by the refrigerant flowing through the refrigerant flow path, thereby eliminating the need for a helium container.

As shown in FIG. 5, the centripetal force support member 8 is fixedly supported by the embedded metal fitting 19 with bolts 20, as shown in FIG.

としての経詩性が一段と向上する。In this way, by providing the coolant flow path 11 in the superconducting coil 3, the superconducting coil 3 can be cooled to an extremely low temperature by the coolant flowing through the coolant flow path 11, thereby eliminating the need for a helium container. This makes it possible to simplify the overall configuration of the SMES and reduce manufacturing costs. Furthermore, since a vacuum container is not required in this embodiment, the workability inside the cavity (during assembly and maintenance) is improved, and the usability of the entire system is further improved.

Further, since a refrigerant for cooling the helium container is not required, the amount of helium during operation can be reduced, and operating costs can be lowered. Furthermore, by eliminating the need for a helium container, there is no welding vacuum boundary, improving vacuum reliability.
