Abstract

The invention relates to the technology of superconducting magnet insulation reliability, aims at realizing the electrical tree observation and image acquisition functions of a simulation superconducting magnet system in a strong magnetic field environment and a low temperature environment, and provides a low-temperature polymer electrical tree initiation method under the electromagnetic field combined effect and a low-temperature polymer electrical tree initiation device thereof. The low-temperature polymer electrical tree initiation device comprises a digital microscope imaging system, a temperature control system, a constant temperature box, a controllable high-voltage pulse power supply and a magnetic field generation device. The temperature control system controls temperature of the constant temperature box through a liquid nitrogen cooling device. The magnetic field generation device is composed of a constant current electromagnetic field generator and an electromagnet. The electromagnet uses a single-yoke U-shaped structure. The polymer is a polymer sampling for performing electrical tree aging. The polymer is arranged in the middle position of the single-yoke U-shaped structure, and the two ends are connected with the controllable high-voltage pulse power supply arranged outside the constant temperature box through a pin-plate electrode structure. The digital microscope imaging system observes the growing situation of the electrical tree in an epoxy resin sample in real time. The low-temperature polymer electrical tree initiation method under the electromagnetic field combined effect and the low-temperature polymer electrical tree initiation device thereof are mainly applied to the occasion of superconducting magnet insulation.

Description

technical field [0001] The invention relates to superconducting magnet insulation reliability technology, in particular, relates to a low-temperature polymer electric dendrite induction device under the combined action of electromagnetic fields. Background technique [0002] At present, the international thermonuclear fusion project has attracted widespread attention. The leading concept of magnetic confinement high-temperature plasma has been proposed internationally for this project.
