摘要： The disclosure relates to a superconducting energy storage and switching apparatus. A superconducting energy storing device, such as a coil, is surrounded and cooled by, for example, liquid helium. A switch comprising a material having relatively high resistivity when normal and superconducting at very low temperatures is electrically connected to the superconducting energy storage device. The switch is immersed in a dewar separate from the coil so that the temperature of the switch can be controlled independently of the temperature of the coil to provide electrical switching capability without loss of energy storing efficiency.

摘要： A persistent current switch adapted to connect the ends of a superconducting coil together and to disconnect the ends thereof includes a vacuum casing and at least a pair of electrodes disposed in the vacuum casing in opposing relationship to each other. Each of the electrodes is provided with a highly conductive contact portion of high-purity metal having a very small resistivity at extremely low temperatures and with at least one superconducting contact portion of superconducting material in alignment with one another in the respective electrodes so that parallel current paths of the highly conductive contact portion and the superconducting contact portion may be simultaneously established when the electrodes are brought into contact with each other. The persistent current flows through the superconducting contact portion in the normal state, but the current is swiftly diverted to the highly conductive contact portion when the S-N transition takes place owing to the deterioration of the critical current value of the superconductor due to the sudden change in conduction current or the application of external magnetic field so that the rapid attenuation of the persistent current can be prevented.
摘要翻译：一种持续电流开关，其适于将超导线圈的端部连接在一起并使其端部断开，其包括真空壳体和设置在真空壳体中的彼此相对关系的至少一对电极。每个电极设置有高纯度金属的高导电性接触部分，其在极低温度下具有非常小的电阻率，并且至少一个超导材料的超导接触部分在各个电极中彼此对准，使得并联电流当电极彼此接触时，可以同时建立高导电性接触部分和超导接触部分的路径。持续电流在正常状态下流过超导接触部分，但是当由于超导体的临界电流值由于突然变化而导致的SN转变发生时，电流迅速转移到高导电性接触部分传导电流或外部磁场的应用，从而可以防止持续电流的快速衰减。

摘要： A switching path for heavy current includes at least one superconductive winding traversible by a current and switchable from superconductive to electrically normally conductive condition through its intrinsic magnetic field, and magnetic shield means of superconducting material disposed in the vicinity of the winding and positioned in a manner that when the shield means are in superconductive condition, the magnetic lines of force produced by the winding during the passage of current therethrough are forced into a longer path (s1) than without the shield means so that the magnetic field within the winding is smaller than the lowest critical field intensity at any point of the winding, and so that when the current in the winding reaches a predetermined intensity (IO) the shielding effect of the shield means disappears at least partially due to the increased magnetic field whereby the magnetic lines of force are shortened and the magnetic field increases within the winding to a magnitude above the highest critical magnetic field intensity at any point of the winding passed by the current of predetermined intensity, the winding and the magnetic shield means being immersed in a coolant and being coolable thereby to superconductive temperature, the winding being embedded in heat insulating material of relatively high disruptive strength so as to avoid direct contact of the winding with the coolant, the insulating material having a thickness at least on a side thereof facing the coolant which affords recooling of the winding to superconductive condition subsequent to actuation of the switching path.
