Abstract

Metallized film capacitors (MFCs) is the essential components of the superconducting magnetic energy storage (SMES) system. In this paper, a polymer insulation film partial discharge(PD) experimental system is established to explore the PD characteristics of biaxially oriented polypropylene (BOPP) and metallized films based on the simulation of insulation defects formed after the self-healing in MFCs. As the size and quantity of defects increase, the distortion of the electric field intensifies, thereby facilitating the occurrence of PD. However, the PD amplitude of the metallized film decreased by about 10%. The PD of BOPP films is mainly internal discharge. The metallized film initially occurs surface discharge. With the applied voltage increasing, the intensity of internal discharge amplifies. Self-healing and PD will cause the loss of electrodes, leading to the degradation in capacitor performance. The difference in PD characteristics between BOPP and metallized films is attributed to the excellent conductivity of the metallized film surface. This property promotes diffusion and combination of the space charge, while reducing the accumulation of charges in the defects. Thus the electric field distortion is reduced, which makes PD more difficult to occur and less intensive.

功率电容器中金属化薄膜自愈合后的局部放电特性研究
金属化薄膜电容器(MFC)是超导磁能存储(SMES)系统的重要组成部分。本文建立了聚合物绝缘薄膜局部放电(PD)实验系统,在模拟 MFC 自愈后形成的绝缘缺陷的基础上,探讨了双向拉伸聚丙烯(BOPP)和金属化薄膜的局部放电特性。随着缺陷大小和数量的增加,电场畸变加剧,从而促进了 PD 的发生。然而,金属化薄膜的 PD 振幅降低了约 10%。BOPP 薄膜的放电主要是内部放电。金属化薄膜最初发生表面放电。随着外加电压的增加,内部放电的强度会放大。自愈和 PD 会导致电极脱落,从而导致电容器性能下降。BOPP 和金属化薄膜在放电特性上的差异归因于金属化薄膜表面的优异导电性。这一特性促进了空间电荷的扩散和结合,同时减少了缺陷处的电荷积累。因此,电场畸变减小,从而使 PD 更难发生,强度降低。
