Description

Technical Field

[0001] The invention relates to the technical field of nuclear fusion devices, and in particular to a supporting device. Background Art

[0002] At present, in the Tokamak device, the support device is used to carry the TF coil (longitudinal field coil, the specific shape is similar to a ring) and other various equipment in harsh environments (such as high temperature, high pressure, strong magnetic field, etc.). Figure 1 ) is supported by multiple tripods and rigidly connected to the equipment above it to ensure the stability of the equipment.

[0003] During the nuclear fusion reaction, the temperature of the TF coil will rise, causing thermal expansion and generating thermal stress.
