摘要

干式直流支撑电容器是柔性直流输电系统的核心器件，其元件卷绕质量直接决定产品的电气性能与长期运行可靠性。针对国产与进口树脂金属化聚丙烯薄膜机械强度差异导致的卷绕工艺适配性问题，基于ANSYS平台构建电容器圆柱元件卷绕过程的二维轴对称有限元模型，采用区域分层法实现计算效率与仿真精度的平衡，系统对比分析两种薄膜在8 N、10 N、13 N 3种典型恒定卷绕张力下的应力响应、变形特性及卷层间压力分布规律。本研究将国产粒料（中原石化FC03R）制备的薄膜编号为树脂A，进口粒料（北欧化工HC300BF）制备的薄膜编号为树脂B。研究结果表明：树脂A纵向弹性模量偏低19.3%，导致其基础层最大等效应力较树脂B低1.72%，最大径向变形低1.18%；卷层间压力呈显著分层特性，外层压力分布差异明显；树脂A强度储备更小，断膜风险更高，卷绕工艺窗口窄于树脂B。进一步通过不同卷绕张力下的加速老化实验验证了仿真结论，发现适中的卷绕张力可使国产薄膜元件获得最优的电容量稳定性。研究结果为国产树脂膜的卷绕工艺参数优化提供了定量理论支撑。

Abstract

Dry-type DC-link capacitors are core components in VSC-HVDC transmission systems. The winding quality of capacitor elements directly determines the electrical performance and long-term operational reliability of the products. In view of the winding process adaptability issues arising from the mechanical strength discrepancies between metallized polypropylene films made from domestic and imported resins

a two-dimensional axisymmetric finite element model of the cylindrical capacitor element winding process is established using the ANSYS platform. The regional layering technique is adopted to optimize the trade-off between computational efficiency and simulation fidelity. The stress behavior

deformation patterns

and interlaminar pressure distributions of the two film types are systematically compared under three constant winding tension levels—8 N

10 N

and 13 N. In this study

the film prepared from domestic granule (Sinopec Zhongyuan Petrochemical FC03R) is denoted as Resin A

and the film prepared from imported granule (Borealis HC300BF) is denoted as Resin B. The study results show that the longitudinal elastic modulus of Resin A is 19.3%lower than that of Resin B. As a consequence

the maximum equivalent stress in the base layer of Resin A is 1.72% lower

and the maximum radial deformation is 1.18% lower than those of Resin B. In addition

the inter-layer pressure exhibits significant layered characteristics

with notable differences observed in the pressure distribution of the outer layers.Resin A has a smaller strength reserve

leading to a higher risk of film rupture and a narrower winding process window compared to resin B. The simulation findings are further validated through accelerated aging tests under different winding tensions

revealing that a moderate winding tension enables domestically produced film elements to achieve optimal capacitance stability. The research results provide quantitative theoretical support for the optimization of winding process parameters for domestic resin films.
