Abstract

The phase-change cooling technology shows its superiority on transient heat dissipation of electronic device, such as IC. It was furtherly investigated to apply this technology to some electric apparatus like generator and power rectifier. In order to fully utilize the capability of phase-change cooling technology in cooling applications of HV power electric apparatus, it is necessary to verify the partial discharge (PD) suppression capability of the phase-change cooling liquid dielectric and the insulation effect caused by the bubble under boiling conditions. In this paper, the partial discharge characteristics of fluorinert dielectric liquid under the nonuniform field are studied with a modified test chamber. The partial discharge signals with and without bubbles are measured and analyzed in detail. The effect of bubble on the partial discharge characteristics under boiling condition is explored. Furthermore, it is revealed that the effects of applied voltage on the bubble motion and PD parameters.

沸点条件下含氟液体排放规律的研究

相变冷却技术在集成电路等电子器件的瞬态散热方面显示出其优越性，并对该技术在发电机、电源整流器等电子器件中的应用进行了进一步的研究。为了在高压电力电器的冷却应用中充分发挥相变冷却技术的能力，有必要对相变冷却液介质的局部放电抑制能力和沸腾条件下气泡引起的绝缘效果进行验证。本文采用改进的试验箱，研究了非均匀场作用下氟惰性介质液体的局部放电特性。对带气泡和不带气泡的局部放电信号进行了详细的测量和分析。探讨了沸腾条件下气泡对部分放电特性的影响。此外，还揭示了外加电压对气泡运动和局部放电参数的影响。
