Embodiment 1

[0052] The varistor of embodiment 1 adopts five KPP-30-300 high-energy zinc oxide varistors of the same model to be connected in parallel, and the rated energy of the zinc oxide varistor formed by parallel connection reaches 150 kilojoules; flow capacity to absorb large current pulses; during the plasma rupture stage, if an overvoltage occurs in the energy processing device, and the voltage amplitude is greater than the varistor voltage of the varistor, the zinc oxide varistor will be turned on and the zinc oxide varistor will start to work , play the role of limiting overvoltage and absorbing energy.

[0053] The pulse capacitor unit in Example 1 uses 70 MKMJ2-5000 pulse capacitors of the same type connected in parallel, with a capacitance value of 0.35 farads, which are used to bear the large current pulse at the moment of rupture and store energy.

[0054] The resistance of the resistance unit of embodiment 1 is used to absorb energy, and is formed by parallel connection of...

Embodiment 2

[0058] The application of the tokamak plasma rupture energy processing device provided by embodiment 2 is as follows: Figure 5 As shown, compared with embodiment 1, the difference is that the three-phase filter of the inverter unit in embodiment 2 uses a single inductor L filter, and other parts are the same; compared with embodiment 1, because embodiment 2 reduces the filter The feedback of the capacitor current reduces the difficulty of control, and the corresponding control unit can reduce a current acquisition module, which reduces the cost; but the filtering effect of the high-frequency harmonics by using a single-inductance L filter is not as good as that of using an LCL filter.

[0059] The flow process of the plasma rupture energy treatment method provided by the present invention is as follows: Image 6 As shown, the plasma rupture energy processing device provided in conjunction with embodiment 1 is specifically described as follows:

[0060] (1) When the plasma ru...

Description

technical field [0001] The invention belongs to the field of energy processing, and more specifically relates to a tokamak plasma rupture energy processing device and processing method. Background technique [0002] In magnetic confinement thermonuclear fusion, a magnetic field is used to confine high-temperature plasma in a circular vacuum chamber to perform circular motion to form a stable plasma current. When the high-energy tokamak plasma breaks and loses confinement, the current drops rapidly, and the internal energy and electromagnetic energy dissipate rapidly, which will cause serious damage to the tokamak device. The sum of the plasma rupture internal energy and electromagnetic energy of the tokamak operating in the future will be on the order of gigajoules, which is a great safety hazard for the tokamak device. Using the energy processing device, combined with the coil coupled with the plasma, the rupture energy is transferred out of the vacuum chamber, and the tra...
