Method for designing insulation thickness of 22.9kV class High-temperature superconducting cable using conversion coefficient

摘要

Disclosed herein is a method for designing an insulation thickness of a 22.9 kV high-temperature superconducting cable wherein conversion coefficients for use in the transmission of electric power. In the insulation thickness designing method, differently from a conventional design method wherein only AC insulation breakdown electric-field, impulse insulation breakdown electric-field, and partial discharge initiation electric-field characteristics of an insulation sheet sample are applied to cable insulation thickness design equations, conversion coefficients, which are obtained in consideration of the effects of shape, area, and thickness along with the respective electric-field values, to the cable insulation thickness design equations, thereby achieving an increase in the accuracy of the insulation thickness of the high-temperature superconducting cable to be manufactured.
