Abstract

The invention provides a superconductivity insulation material electrical characteristic test device which comprises a first casing, a second casing, a refrigerator, a test cable and a vacuumizing device. The first casing is provided with a first inner cavity, the second casing is made of heat conduction materials and arranged in the first inner cavity, the second casing is provided with a second inner cavity, a test electrode is positioned in the second inner cavity, a first cooling head of the refrigerator is fixedly connected with the second casing, the first end of the test cable is connected with the test electrode, the second end of the test cable is used for being connected with test equipment outside the first casing, the vacuumizing device is respectively connected with the first casing and the second casing and used for vacuumizing the first inner cavity and the second inner cavity, and the second casing is connected with the vacuumizing device through a first air pipe arranged in the first inner cavity. The technical scheme of the superconductivity insulation material electrical characteristic test device is that a test environment meeting work condition requirements of an international thermonuclear experimental reactor (ITER) device can be simulated in the second inner cavity to provide test methods for researching insulation material electrical characteristics when a superconducting magnet runs stably.

Description

technical field [0001] The invention relates to the technical field of high voltage and insulation, in particular to a device for testing electrical characteristics of superconducting insulating materials. Background technique [0002] The International Thermonuclear Experimental Reactor (ITER) is an important stage in realizing the commercialization of endless clean energy fusion energy, and its goal is to verify the scientific and technological feasibility of peaceful use of fusion energy. Its main components include: superconducting magnet system, external vacuum Dewar, internal and external cold shields, vacuum chamber and its internal components, and magnet feeder system and other components.
