摘要

为研究局部放电对油浸式电力设备绝缘劣化的影响，文中建立了油纸绝缘局部放电试验平台，探讨了局部放电电压和持续时间对绝缘纸损伤、绝缘油中游离碳含量及形态的影响。实验结果表明，局部放电电压和放电时间显著影响绝缘纸劣化和游离碳生成。通过外观形貌和图像分析发现，随着放电电压和时间的增加，绝缘纸表面碳化痕迹增多，损伤面积明显扩大。当放电电压从20 kV升至45 kV时，放电120 s后游离碳含量增加约50.88%，且碳颗粒尺寸显著增大。放电时间延长导致游离碳含量和颗粒尺寸增加，尤其在45 kV电压下，放电时间从30s延长至120 s，游离碳的增长率达到61.41%。文中揭示了局部放电与油纸绝缘劣化的关系，为油浸式电力设备的绝缘监测与维护提供了理论支撑和实验依据。

Abstract

To investigate the impact of partial discharge (PD) on insulation degradation of oil-immersed electrical equipment

a partial discharge testing platform for oil-paper insulation is set up. The impact of PD voltage and duration on the damage of insulation paper

the contents and morphology of free carbon in insulating oil is discussed. The experimental results show that both the PD voltage and duration induce a significant influence on the degradation of insulation paper and the generation of free carbon particles. It is found through visual morphology and image analysis that with the increase of PD voltage and duration

carbonization marks on the insulation paper surface increases

and the damage area expands evidently. When the discharge voltage is increased from 20 kV to 45 kV

the free carbon content is increased by approximately 50.88%after PD process for 120 s

with a notable increase in the size of carbon particles. The long discharge time leads to the increase of both free carbon content and particle size. Especially

at voltage of 45 kV

the discharge time is extended from 30 s to 120 s

and the growth rate of free carbon is upto 61.41%. This study in this paper reveals the relationship of partial discharge and oil-paperin sulationdegradation

providing theoretical support and experimental basis for insulation monitoring and maintenance of oil-immersed electrical equipment.
