この発明は、超電導マグネットもこコイル固定用の樹脂
を均一かつ効率的に含浸させるための樹脂含浸方法に関
する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a resin impregnation method for uniformly and efficiently impregnating a superconducting magnet with a resin for fixing a coil.
超電導マグネットは、巻線線材の電磁力による動きがあ
ると発熱してクエンチを起こすなど、性能が安定しない
。従って、巻枠に巻回したコイルの線材間に樹脂を含浸
させ、この樹脂を介してコイル線材を一体化することが
行われている。The performance of superconducting magnets is unstable, as movement caused by the electromagnetic force of the winding wire generates heat and causes quenching. Therefore, resin is impregnated between the wire rods of the coil wound around the winding frame, and the coil wire rods are integrated through the resin.
この場合のマグネットに対する樹脂含浸の従来法を第２

引された樹脂からの更なる脱泡を考えて小量吸引、樹脂
人口８の閉鎖、一定時間の排気の各工程を多数回繰り返
す。In this case, the conventional method of impregnating the magnet with resin is
As shown in the figure. As shown in the figure, a superconducting coil 2 wound around a stainless steel winding frame 1 is placed in a pressure vessel 11. First, the resin cap 8 of the pressure vessel 11 is closed, the outlet 9 is opened, and the inside of the pressure vessel 11 is evacuated by the vacuum pump 7. after that,
4. The resin container 8 is opened, and the resin 10, which has been previously blended and defoamed and placed in the container 5, is sucked into the pressure container 11. In addition, in this work, the steps of suctioning a small amount, closing the resin population 8, and evacuation for a certain period of time are repeated many times in order to infiltrate the resin into the superconducting coil 2 and further defoam from the sucked resin. .
次に、超電導コイル２が完全に浸漬される位置まで圧力
容器１１内に樹脂１０が導入されたら、樹脂人口８を閉

ために一定時間の排気を行なう。さらに、真空ポンプ７
を外し、出口９からの窒素ガス等の導入により圧力容器
１１内を加圧してコイル中に樹脂を更に含浸させる。Next, when the resin 10 is introduced into the pressure vessel 11 to the point where the superconducting coil 2 is completely immersed, the resin port 8 is closed, and the resin 10 is kept at a constant temperature for degassing and promoting penetration of the resin 10 into the superconducting coil 2. Exhaust time. Furthermore, vacuum pump 7
is removed, and the inside of the pressure vessel 11 is pressurized by introducing nitrogen gas or the like from the outlet 9 to further impregnate the resin into the coil.
上述の従来法によると、必要量を越す量の樹脂を真空引
きされた圧力容器１１中に導き、その導入樹脂中に超電
導コイルを浸漬してコイル中に樹脂を浸透させるため、
導入樹脂の圧力低下、樹脂導入による容器内真空度の低
下があり、そのため、それ等の圧力差で決まるコイル中
への樹脂浸透力が不充分となることに加えて脱泡も不充
分となり、コイル内に樹脂未含浸部が生じ易いと云う欠
点がある。According to the conventional method described above, an amount of resin exceeding the required amount is introduced into the evacuated pressure vessel 11, and the superconducting coil is immersed in the introduced resin to infiltrate the resin into the coil.
There is a decrease in the pressure of the introduced resin and a decrease in the degree of vacuum inside the container due to the introduction of the resin, and as a result, in addition to insufficient resin penetration into the coil, which is determined by the pressure difference, defoaming is also insufficient. There is a drawback that resin-unimpregnated areas tend to occur within the coil.
また、真空引きする空間の容積が必要以上に大きく、作
業手順も複雑なため、含浸に時間がかかる欠点もある。In addition, the volume of the space to be evacuated is larger than necessary and the working procedure is complicated, so there is also the drawback that impregnation takes time.
この発明は、上記の課題を解決するためになされたもの
で、その目的は、超電導コイルへの樹脂含浸を均一かつ
効率的に行なえる方法を提供することにある。This invention was made to solve the above problems, and its purpose is to provide a method that can uniformly and efficiently impregnate a superconducting coil with a resin.
この発明は、コイル巻線後の巻枠外周にパイプを接合し
てこのパイプと上記巻枠とでコイルを密封する圧力容器
を形成し、この容器内を真空引き後、予め脱泡された樹
脂を圧力容器内に吸引することを特徴とする。This invention involves joining a pipe to the outer periphery of the winding frame after coil winding, forming a pressure vessel that seals the coil with this pipe and the winding frame, and after evacuating the inside of this vessel, a pre-defoamed resin is It is characterized by suctioning into a pressure vessel.
コイルの巻枠とその外周に接合するパイプとで圧力容器
を構成すると、容器内に流入した樹脂はコイル内の空間
を通って容器出口に向かわざるを得ないので、容器内に
働く吸引力の全てがコイルへの樹脂浸透力として有効に
活かされる。When a pressure vessel is constructed with a coil winding frame and a pipe connected to its outer periphery, the resin flowing into the vessel has no choice but to pass through the space inside the coil and head toward the outlet of the vessel, which reduces the suction force acting inside the vessel. All of this is effectively utilized as the resin penetration power into the coil.
また、無駄な空間を真空引きせずに済むのに加えて、樹
脂導入による容器内真空度の低下（浸透力の低下）を樹
脂吸引と平行した真空引きによって補うことが可能であ
り（従来法では、容器への樹脂導入と真空引きを平行さ
せても樹脂の圧力が直接真空ポンプ側に逃げるので浸透
力の低下は補えない）、これによって均一含浸と作業の
効率化の目的が共に達成されることになる。In addition, in addition to eliminating the need to vacuum up wasted space, it is possible to compensate for the decrease in the degree of vacuum inside the container (decrease in penetration power) due to the introduction of resin by vacuuming in parallel with the resin suction (conventional method). In this case, even if the introduction of the resin into the container and the evacuation are performed in parallel, the pressure of the resin will escape directly to the vacuum pump side, so the decrease in penetration power cannot be compensated for.)This achieves both the goals of uniform impregnation and improved work efficiency. That will happen.
以下、この発明の方法の一実施例を第１図に基いて説明
する。An embodiment of the method of the present invention will be described below with reference to FIG.
図のように、ステンレス巻枠１に超電導コイル２を巻線
し終えたら、１の外周にステンレスパイプ４を気密に溶
接する。そして、ステンレス巻枠に設けである樹脂人口
８と出口９に図のように樹脂容器５と真空ポンプ７を接
続する。このとき、真空ポンプ７と出口９との間には真
空びん６を配置しておく。３は、２と４の間に必要に応
じて設けるガラステープである。As shown in the figure, after winding the superconducting coil 2 around the stainless steel frame 1, a stainless steel pipe 4 is hermetically welded to the outer periphery of the frame 1. Then, as shown in the figure, the resin container 5 and vacuum pump 7 are connected to the resin cap 8 and outlet 9 provided on the stainless steel winding frame. At this time, a vacuum bottle 6 is placed between the vacuum pump 7 and the outlet 9. 3 is a glass tape provided between 2 and 4 as necessary.
この後、先ず樹脂人口８を閉め、真空ポンプ７により出
口９から１と４の２者で構成される圧力容器内を排気す
る。次に、その排気によって上記容器の内部真空度が所
定値に達したら、ここで樹脂入口８を開き、予め容器５
に入れておいた脱泡済の樹脂を超電導コイル２内に吸引
する。なお、このとき、樹脂の含浸空間容積が小さけれ
ば、真空ポンプ７を停止させてもよいが、好ましくはポ
ンプ７による真空引きを継続さセておく。After this, first, the resin cap 8 is closed, and the inside of the pressure vessel composed of the two parts 1 and 4 is evacuated from the outlet 9 by the vacuum pump 7. Next, when the internal vacuum level of the container reaches a predetermined value due to the evacuation, the resin inlet 8 is opened and the container 5 is opened in advance.
The defoamed resin that has been placed in the superconducting coil 2 is sucked into the superconducting coil 2. At this time, if the volume of the resin-impregnated space is small, the vacuum pump 7 may be stopped, but preferably the vacuum pump 7 is continued.
以上のようにして吸引を続行すると、樹脂は超電導コイ
ル２内に十分に含浸された後、出口９よリオーバフロー
して真空びん６に流入する。そこで樹脂人口８及び出口
９を閉め、真空びん６、真空ポンプ７、容器５を外し樹
脂を硬化させる。When the suction is continued as described above, the superconducting coil 2 is sufficiently impregnated with the resin, and then it overflows through the outlet 9 and flows into the vacuum bottle 6. Then, the resin cap 8 and the outlet 9 are closed, the vacuum bottle 6, the vacuum pump 7, and the container 5 are removed, and the resin is cured.
なお、この発明の方法は、この実施例に限定されない。Note that the method of the present invention is not limited to this example.
例えば巻枠とこれに接合するパイプとで構成される圧力
容器の下部に設ける樹脂人口８を複数個点在させて実施
してもよく、この場合、コイルの全周への樹脂の回り込
みが早まるため、より好ましくなる。For example, a plurality of resin layers 8 may be installed at the bottom of a pressure vessel consisting of a winding frame and a pipe connected thereto, and in this case, the resin can spread around the entire circumference of the coil more quickly. Therefore, it becomes more preferable.
以上説明したように、この発明の方法によれば、巻枠と
これに接合するパイプで超電導コイルを密封する圧力容
器を構成して無駄な真空引きを無くし、さらに、この真
空引きで生じる真空圧を無駄なく活かしながら樹脂含浸

く迅速に樹脂を含浸できると云う効果が得られる。As explained above, according to the method of the present invention, the winding frame and the pipe connected thereto constitute a pressure vessel that seals the superconducting coil, eliminating unnecessary evacuation, and furthermore, the vacuum pressure generated by this evacuation is Since the resin impregnation is carried out while utilizing the superconducting coil without wasting it, it is possible to impregnate every corner of the superconducting coil with the resin quickly and with good workability.
また、巻枠に接合したパイプは、そのま〜残してコイル
の押え部材として利用できるので、電磁力からの保護を
目的として従来コイル上に施していたステンレスの押え
巻きが不要になると云う付随効果も生じる。In addition, the pipe connected to the winding frame can be left as is and used as a holding member for the coil, which has the additional effect of eliminating the need for the stainless steel holding member that was conventionally placed on the coil to protect it from electromagnetic force. also occurs.
