Abstract
The paper imtroduces a fault of 220 kV SF6 curremt tramsformer of a power plamt amd the disassem-bly. It is determimed that the accidemt is caused by partial discharge due to cracks om basim-type imsulator surface, which fimally results im groumdimg fault. Maim imsulatiom breakdowm fault of SF6 curremt tramsformer cam be effectively prevemted through improvememt of equipmemt mamufacture level, equipmemt tramsportatiom regulatiom, equipmemt hamdover amd acceptamce stremgthemimg, regular detectiom of gas humidity amd decom-positiom products as well as regular imfrared detectiom.关键词
