PURPOSE:To make it possible to obtain a superconducting coil whose entire coil can be clamped uniformly without laying out a bolt in the inner peripheral part of the coil by dispersing and transmitting compression force produced by a bolt laid out in the outer peripheral part of the coil to both the inner and the outer peripheral sides of a conductor. CONSTITUTION:In a superconducting coil which clamps a conductor 4 coiled with a superconducting wire with a bolt 6 by way of a pressure plate 5, a pressure dispersion plate 7 is installed so as to disperse compression force between the conductor 4 and the pressure plate 5. Therefore, the compression force produced by the bolt 6 installed to the outer peripheral part of the coil is transmitted to the pressure dispersion plate 7 once by way of the pressure plate 5 and then transmitted to the conductor 4. This transmitted compression force is received by the central part of the pressure dispersion plate 7 but not received by the end of the plate. It is, therefore, possible to disperse and transmit the compression force by the bolt 6 uniformly to both the inner and outer peripheral parts of the conductor. |
