POLOIDAL FIELD COIL STRUCTURE OF HINGE TYPE FOR SUPERCONDUCTING TOKAMAK

摘要

A PF(Poloidal Field) coil structure of a hinge type of a superconducting tokamak is provided to absorb contraction transformation and intensity enough to endure an electromagnetic force by acquiring thermal, structural, and electrical stability of a poloidal coil. A PF coil structure of a hinge type of a superconducting tokamak includes a PF coil fixing unit(10), a connection block(20), and a base block(30). The PF coil fixing unit(10) fixes a PF coil. The connection block(20) is connected to one side of the PF coil fixing unit(10) by a hinge. The base block(30) is connected to the other side of the connection block(20) by the hinge, and is attached to a toroidal coil. The PF coil fixing unit(10) includes a lower side block(11), inner/outer side blocks(12,13), and an upper block(14). The lower side block(11) supports a lower part of the PF coil. The inner/outer side blocks(12,13) are vertically attached to inner/outer sides of the lower side block(11). The upper block(14) is horizontally attached to upper parts of the inner/outer side blocks(12,13).
