Final Paper
Supercritical carbon dioxide (scCO2) has garnered significant attention due to its excellent insulating strength and transport properties. Current international research primarily focuses on its breakdown characteristics near the critical point in micron-scale gaps. However, variations in power source types and polarities result in breakdown voltage data that lack broad reference significance, and there is a lack of discussion on voltage dispersion. For the same gap distance, slightly non-uniform electric fields exhibit similar DC, power frequency breakdown voltages (amplitudes), and 50% impulse breakdown voltages, with no significant polarity effect in asymmetric electrodes, indicating these data are valuable references. In this study, an independent supercritical discharge system was established using sphere-to-plate electrodes to generate a slightly non-uniform electric field with a non-uniformity coefficient of 0.99. Breakdown experiments were conducted at a 0.3 mm gap. The breakdown strength of scCO₂ was compared with common insulating media, and the regularity of its breakdown voltage dispersion was discussed. The results provide experimental data and a theoretical foundation for the application of scCO2 in switching technology.
