Electrode system for continuous AC breakdown voltage test in liquid nitrogen

摘要

The present invention relates to an electrode system capable of continuously performing an insulation breakdown test of an insulator of a superconducting power cable in a liquid nitrogen state. Specifically, an insulator starting roller having an insulator roll is formed on a lower support plate, and the insulator starts Phase by starting rollers. Guide rollers for guiding the insulator passing between the lower electrodes are formed on the lower support plate and the middle support plate, respectively, and an insulator recovery roller for winding and recovering the insulator guided by the guide roller is formed on the upper support plate. It relates to an electrode breakdown test electrode system, which is formed to drive a driving motor for driving the insulation and the breakdown test of the insulator roll by the rotation of the rollers in a liquid nitrogen state.
