Embodiment Construction

[0018] The technical solutions and beneficial effects of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 As shown, in the first embodiment, the radiation-resistant composite cable based on magnesium-aluminum spinel insulation provided by the present invention includes a metal conduit 1 , a magnesium-aluminum spinel insulation layer 2 , and a metal armor 3 from the inside to the outside. The exterior of Metal Armor 3 is a vacuum environment. The hollow part of the metal conduit 1 is a cooling channel 4 . The cooling channel 4 is filled with coolant to actively cool the metal conduit 1 .

[0020] Coolant can choose water, CO2, helium. The metal armor 3 can be selected from austenitic stainless steel, martensitic stainless steel, nickel-based alloy; the metal conductor 1 can be selected from oxygen-free copper, zirconium chromium copper, and stainless steel. The main compon...

Abstract

The invention belongs to the field of power transmission, and specifically discloses an anti-radiation composite cable based on magnesium aluminate spinel insulation. The cable comprises a conductor, a magnesium aluminate spinel insulation layer and a metal armor from the inside to the outside. The outside of the metal armor is a vacuum environment. The main component of the magnesium aluminate spinel insulation layer is MgAl2O4, wherein the weight percentage of MgAl2O4 is greater than 99%. The conductor is a metal conduit or a plurality of metal wires. Through the design of the metal armor, the cable can carry out the power transmission under the vacuum conditions. Through the design of the magnesium aluminate spinel insulation layer with the weight percentage of MgAl2O4 being greater than 99%, the cable solves a problem that the insulating performance decreases because a cable is liable to absorb moisture.

Description

technical field [0001] The invention belongs to the field of power transmission, in particular to a radiation-resistant composite cable based on magnesium-aluminum spinel insulation. Background technique [0002] In order to suppress the instability of the plasma and realize various tokamak fusion experimental functions, a variety of internal coils need to be installed in the vacuum chamber as the core component of the tokamak fusion experimental device, including various diagnostic coils facing the plasma, strong Shielding coils in magnetic fields, fringe localized mode and vertical instability coils, divertor trimming coils, TBM active compensation coils, etc. Because these internal coils will face the strong irradiation environment of fusion reaction (neutron irradiation and gamma ray irradiation), the working temperature is relatively high (above 300 degrees), so ordinary insulating materials such as epoxy resin and glass fiber cannot be used To achieve electrical insul...
