摘要：
For size reduction of gas insulated switchgears (GIS), application of permittivity-graded material to insulating spacer has been studied. The electric-field-enhancement close to the lamination interface of the permittivity-graded material obtained by laminating epoxy composites with different permittivities was investigated. The FEM simulation revealed that the increase of the layer number of the permittivity-graded material could reduce the field enhancement close by the lamination interface, even when considering electric field distortion near the individual high permittivity particles filled in each layer. © 2018 The Institute of Electrical Engineers of Japan.
