させることになり、低温容器の冷却効果も悪化す
ることになつた。 Generally, superconducting coils are used by being immersed in a coolant such as liquid helium. When the superconducting coil quenches, it releases a large amount of heat into liquid helium,
Liquid helium evaporates. Since a large amount of this evaporated helium gas is generated, it must be promptly discharged to the outside of the cryogenic container, and therefore a thick discharge pipe for discharging the helium gas is required. However, in low-temperature containers used for superconducting coils for maglev trains, etc., it is difficult to install a thick helium gas discharge pipe due to space constraints, and when the discharge pipe becomes thick, helium gas causes convection within the pipe, which further increases the During acceleration and deceleration, liquid helium flows into the discharge pipe, allowing heat from the outside to enter the low-temperature container, which deteriorates the cooling effect of the low-temperature container.

太いガス排出管を用いる必要がなくなる。 The present invention provides an absorption tube in the refrigerant storage container, prevents refrigerant from being replenished from the refrigerant storage container to the superconducting equipment storage container when abnormal evaporation of refrigerant occurs in the superconducting equipment storage container, and furthermore, In order to suck out the refrigerant in the storage container, the refrigerant is sucked up by an absorption pipe. This prevents abnormal evaporation of the refrigerant, so there is no need to use a thick gas exhaust pipe like in the past.
以下、本発明の代表的実施例を図面を参照しな

It consists of a refrigerant storage container 6 that is supplied via a pipe 5.

つている。 The refrigerant storage container 6 also includes a supply pipe 7 for receiving the refrigerant 3 from outside and a discharge pipe 8 for discharging the evaporated gas of the refrigerant 3. When this occurs, the supply of refrigerant 3 into the superconducting equipment storage container 2 is cut off, and the refrigerant 3 inside the superconducting equipment storage container 2 is sucked out.
An absorption tube 9 is provided, the tip of which is located near the flow path 4 and the supply tube 5. Further, the absorption pipe 9 can discharge refrigerant from a discharge port 11 via a safety valve 10.
次に動作について説明する。 Next, the operation will be explained.

is being cooled. If evaporative gas is generated, it is discharged from the exhaust pipe 8.

り冷却を行う。 Here, when a quench occurs in the superconducting coil 1, a large amount of heat is generated, and the refrigerant 3 suddenly becomes a large amount of abnormal evaporated gas, which is discharged from the exhaust pipe 8. When the exhaust of the evaporative gas is finished, the refrigerant 3 is replenished from the refrigerant storage container 6 to the superconducting equipment storage container 2, and a large amount of abnormal evaporative gas is generated again and is discharged from the exhaust pipe 8. When such a large amount of abnormal evaporative gas is generated,
This abnormal evaporative gas generates abnormal pressure inside the superconducting equipment container 2 and the refrigerant storage container 6, and the safety valve 10
is activated, the absorption pipe 9 is opened, and the evaporated gas is discharged from the discharge port 11. Through these operations, the absorption pipe 9 absorbs the refrigerant 3 near the refrigerant storage container 6 side of the flow path 4 and the supply pipe 5, and prevents the refrigerant 3 from being replenished into the superconducting equipment storage container 2. Furthermore, since the refrigerant 3 is rapidly absorbed near the refrigerant storage container 6 side of the supply pipe 5, the refrigerant 3 stored in the superconducting equipment storage container 2 is also absorbed. By the above operation, the refrigerant 3 in the superconducting equipment storage container 2 is exhausted, and abnormal evaporation gas of the refrigerant 3 is no longer generated. Then, when the quenching of the superconducting coil 1 is resolved, cooling is performed by replenishing the refrigerant 3 into the superconducting equipment storage container 2.

Although the safety valve 10 is used as a means for detecting the occurrence of abnormal pressure inside the valve and distributing it, a break plate may be used, the valve may be opened by human supervision, or The valve may be opened by detecting this and using this detection as an electric signal.
尚、補給管５は超電導機器収納容器２内の冷媒
３を吸収する必要のない場合には不要である。 Incidentally, the supply pipe 5 is not necessary when there is no need to absorb the refrigerant 3 in the superconducting equipment storage container 2.

却効率も向上するなど優れた効果を奏する。 As is clear from the above explanation, if the low-temperature container according to the present invention is used, even if abnormal evaporative gas occurs, the absorption tube will immediately prevent refrigerant from being replenished into the superconducting equipment storage container, and Since it absorbs the refrigerant, there is no need to use the conventional thick exhaust pipe for evaporative gas, and the exhaust pipe is sufficient to discharge the evaporative gas under normal conditions.Therefore, it takes up less space and reduces heat intrusion. It has excellent effects such as reducing the amount of water and improving cooling efficiency.
