【発明の詳細な説明】 〔発明の目的〕 （産業上の利用分野） 本発明は超電導エネルギー貯蔵コイルの巻線構成技術

エリアを必要とする。(Prior Art) Generally, superconducting energy storage coils are generally classified into two types. One of them is called a poloidal type, and as shown in FIG.
A conductor is wound around to form the winding portion 1.
The other type is called a toroidal type, and is a type in which a large number of toroidal magnetic field coils 4 are arranged on a circle circle 5 as shown in FIG. Here, the poloidal type has a radius R
Since the hoop force proportional to is large, a structure supported by underground rock is generally proposed, which is expensive in cost. In addition, since the magnetic circuit is not closed, the leakage magnetic field is large, and its countermeasure is a serious problem. , Requires a large installation area.

イドコイルよりはるかに高価である。On the other hand, the toroidal type has a small magnetic field because it closes the magnetic circuit, but the area required for installation is still large, and because many coils are arranged circumferentially, the manufacturing cost is, for example, a linear solenoid with the same magnetic energy. Much more expensive than a coil.

There are various problems in terms of manufacturing cost and leakage magnetic field.

ない。(Operation) In such a structure, since the magnetic circuit is first closed, the leakage magnetic field is very small and the radial magnetic field component in the linear solenoid coil winding portion is small, so that the axial compression force of the solenoid coil is the same. Very small compared to. On the other hand, the linear solenoid coil that stores most of the energy is much easier to manufacture than the conventional type poloidal type or toroidal type. Therefore, it is highly reliable and low cost. Further, since the linear solenoid coils can be installed adjacent to each other, there is no circular dead space unlike the conventional type, and the required installation area is small.
（実施例） 以下、本発明を図面に示す一実施例を参照して説明す

抑制すると共に組立・分解を容易にする。FIG. 1 shows a sectional view of a coil according to the invention. In this coil, two linear solenoid coils are arranged in parallel on the plane of the drawing, and an arc-shaped solenoid coil is arranged at the end thereof. The conductor is wound around the winding frame 3 to form the winding portion 1. In addition, based on the results of examination of stress design of axial compression force and ease of maintenance, the coil is divided into multiple,
The winding frame of the divided portion has a joint structure with the flange 2. The axial compression force acting on the winding portion by the flange 2 is independent for each divided portion, and it is possible to suppress the generation of an excessive axial compression force at the center of the winding portion and to facilitate the assembly / disassembly.

は貯蔵エネルギー増大に対応して直線状ソレノイドコイ
ルの直線部長さを長くすればよくこれに伴う不都合な問
題は基本的にない。Most of the coils can be composed of linear solenoid coils, which can be sufficiently supported by conventional superconducting coil manufacturing technology. Therefore, even if it is a coil that stores a huge amount of energy, it is possible to manufacture it with the extension of the existing technology.
It has the advantages of high reliability and low cost. Conventionally, the coil diameter of the poloidal type increases as the stored energy increases. In the toroidal type, the number of toroidal coils increases, and therefore the circle center circle 5 shown in FIG. 3 in which each coil is arranged increases. This inevitably leads to an increase in electromagnetic force and an increase in required installation area. However, in the coil according to this embodiment, it is sufficient to lengthen the linear portion of the linear solenoid coil in response to the increase in stored energy. There is basically no problem.

地から軸長が制限されることは基本的にないといった利
点を有する。In general, since the magnetic circuit of the linear solenoid coil is not closed, the radial magnetic field component increases at the end, which increases the axial compressive force proportional to the length of the linear portion, which causes buckling of the winding. Therefore, the stress design condition becomes severe. However, according to this embodiment, since the magnetic circuit is closed, the axial compression force is very small. Therefore, there is an advantage that the axial length is basically not limited from the viewpoint of stress design.
２つの直線状ソレノイドコイルを隣接配置できるため
従来方式のような円状のデッドスペース部がなく、必要
設置エリアが小さくなる。Since the two linear solenoid coils can be arranged adjacent to each other, there is no circular dead space as in the conventional method, and the required installation area is reduced.

そのため低コストで高い信頼性を有する超電導エネルギ
ー貯蔵コイルを提供し得る。Since the present invention is a superconducting coil having a closed magnetic circuit mainly composed of a linear solenoid coil, the leakage magnetic field and the required installation area are smaller than those of the conventional coil, and the manufacturing is easy.
Therefore, a superconducting energy storage coil having low cost and high reliability can be provided.
