| PURPOSE:To enable the title energy accumulating device to instantaneously respond to the request for a system stabilizing operation while satisfactorily keeping the normal energy accumulated state in a power system incurring no loss at all. CONSTITUTION:A parallel circuit comprising the first superconducting coil 1 and a superconductive permanent current switch 2 is connected to an AC.DC converter 4 connected to a power system 8 through the intermediary of a switch 3 simultaneously the first superconducting coil 1 and the second electromagnetically coupled superconductive coil 5 are connected to the AC-DC converter 4 through the intermediary of an AC breaker 6 and a protective resistor 7. On the other hand, at the request for the title system stabilizing operation, the ACs DC converter 4 is immediately deblocked without open-circuiting said superconducting permanent current switch 2 so that the accumulated energy of the first superconductive coil may be charged and discharged between the power system 8 through the intermediary of the second superconductor coil 5 to detect any quenching phenomenon observed in the first and second superconducting coils 1, 5 by detectors 9a, 9b for protecting said coils 1, 5 by open-circuiting the AC breaker 6. | ||||||

| PURPOSE: To perform a protective discharging process through a small number of short-circuit switches by providing each winding module with a short-circuit switch, so as to selectively short-circuit solenoid coils, and providing a bypass switch which turns off a faulty or defective winding module by selectively by-passing it. CONSTITUTION: For controlling a voltage generated in the winding of a coil, respective modules 9a to 9c are provided with short-circuit switches 43a to 43c in each module 9. Layer winding coils of the modules are symmetrical, so that when it is assumed that the level of a refrigerant drops from the top to the bottom, respective winding coils 11, 13, and 15, 17 can be observed independently of one another in the case of emergency discharging. Each module pair are provided with a pair of bypass switches 97 and 99, and a faulty module is detached from the circuit by opening a switch 97 and closing a switch 99. | ||||||

| PURPOSE:To prevent the breakage of a thyristor by a method wherein a diode is connected in forward direction between the gate electrode of the protective thyristor, connected between both ends of a superconductive coil, and the prescribed section of the superconductive coil. CONSTITUTION:A permanent current switch 3 and a thyristor 4 are parallel- connected to the superconductive coil 2 placed in a cryostat 1. A diode 7 is connected in forward direction between the gate electrode 5 of the thyristor 4 and the intermediate tap 6 of the coil 2. When a switch 3 is quenched, a gate current runs on the thyristor 4 through the diode 7, the thyristor 4 is turned ON, and the voltage at both ends of the coil 2 comes down to the threshold voltage of the thyristor 4. As a result, the voltage between the tap 6 and the cathode of the thyristor 4 drops to the threshold voltage or below of the diode 7, and the supply of the gate current to the thyristor 4 is stopped. | ||||||

| PURPOSE:To enable to sharply change the resistance value of a resistor by a method wherein the resistor is composed of the metal such as copper, aluminum and the like having a large resistance changing rate, the resistor is cooled by liquid nitrogen before application of a current, and the liquid nitrogen is evaporated by heating the resistor. CONSTITUTION:The titled protective circuit consists of a superconductive coil 1, a cryostat 2, a resistor 3, a liquid nitrogen chamber 4, a switch 5, with which coil current will be cut off in order to move the coil current to the resistor, and a power source 6 which excites the coil. Also, when an ordinary resistor 7 is used in parallel with a resistor 3 which is cooled by liquid nitrogen, the range of variation in resistance value of synthesized resistance is made smaller, and the thermal input to the resistor by the cooling of liquid nitrogen can be reduced, and the constitution of the resistor can be simplified as a whole. As the material having the large temperature variation, an incandescent lamp can be used, and the same effect can be obtained by the resistor which is formed by having a tungsten wire sealed up in a vacuum atmosphere. | ||||||

| PURPOSE:To make sure protection on normal conduction dislocation of a magnet while eliminating the loss of power on normal conduction by connecting an element conducted at set voltage or more in series with a discharge resistor. CONSTITUTION:A superconducting magnet 1, a discharge resistor 2, a diode element 3, a power supply 4 and a DC breaker 5 are connected as shown in the figure. Since an element of a high forward voltage drop is used as the diode element 3 and the n elements are connected in series, currents do not flow to the discharge resistor 2 in a dislocation protective circuit even when rise or fall currents flow through the magnet 1, and power is not consumed. When the magnet 1 is normal conduction dislocated, voltage at both terminals of the dislocation circuit rises by opening a breaker 5, energy stored in a coil flows through the discharge resistor 2 and the diode element 3 and consumed, and protection is completed. | ||||||
