摘要
围绕干式自愈式电容器展开研究。从其关键特性出发，剖析击穿机理变化引发的问题，简述基膜与粗化膜粒料差异。基于金属化膜圆元件特性，分析卷绕张力对自愈能量影响，得出膜层间最大压强与元件直径成正比结论。针对导电极板薄致损耗大的特点，探讨成因，介绍油浸式全膜电容器“净化”位垒效应，分析其外壳温升高于油浸式的原因。依据热传导理论，分析干式电容器对壳绝缘及散热难题，建议降低对壳绝缘电压，对10kV级电容器装置提出分级绝缘设计，由绝缘平台承担系统绝缘水平。此外，分析温度、过压力等非电保护现存问题并提建议。针对电容无级变化特性，探讨内部故障保护问题，提出容衰与故障保护协同及安全容衰概念，依据IEC 63210标准，建议以破坏性试验验证安全容衰可靠性。
Abstract
The ersearch on dry-type self-healing capacitor is performed. Starting from its characteristics， the issues due to breakdown mechanism variation is analyzed，andthe differences between base-film and roughened-film polypropylene granules is briefly described. Based on the characteristics of metallized film circular elements，the influence of winding tension on self-healing energy is analyzed，and the conclusion that the maximum pressure between the film layers is directly proportional to the element diameter is made. The causes of large losses due to thin conductive plate of self-healing capacito are discussed. The“purification”barrier effect of oil-immersed all-film capacitor is introduced and the reasont that the temperature rise of shell of the self-healing capacitor is higher than that of oil-immersed one is analyzed. Based on the theory of heat conduction，an analysis on the insulation and heat dissipation problems of dry-type capacitors is conducted and the reduction of the insulation voltage to the shell is suggested. For 10kV capacitor device， a graded insulation design is proposed and the insulation level of the system is undertaken by the insulation platform. Furthermore，the the existing problems of such non-electrical protection as temperature protection and over-pressure protection are analyzed and suggestions are proposed. As for the stepless capacitance vriation of self-healing capacitor，the internal fault protection issues are discussed，and the concept of coordination between capacitance decay and fault protection，as well as the concept of safe capacitance decay are proposed. Based on the IEC 63210 standard，it is recommended to verify the reliability of safe capacitance decay through destructive tests.
