ビスマス系高電圧酸化亜鉛バリスタの電気的特性と微細構造に関する研究 ビスマスケイ コウデンアツ サンカ アエン バリスタ ノ デンキテキ トクセイ ト ビサイ コウゾウ ニカンスル ケンキュウ Study on the electrical properties and microstructure of bismuth-based high voltage zinc oxide varistors 郑, 雨萌 30597 テイ, ウメ 50962015 Zheng, Yumeng 0000-0001-6099-1959 酸化亜鉛バリスタ 課電劣化 ZnO varistor electrical degradation The author's aim is to investigate ZnO varistors with high voltage to 1000V/mm and good resistance to electrical degradation, which could be applied to the UHV transmission systems and reduce ZnO varistor element amounts in surge arresters. The conduction processes in ZnO varistors is clarified. By adjusting additive type and amounts in ZnO the electrical properties of ZnO varistors can be controlled. Based on this recipe, Y, Cr, Ni, B, Si oxides were added in this study. These oxides can be divided into two categories, the Y doping group and the Si doping group. doctoral thesis 2022-03-22 application/pdf application/pdf 甲第1215号 https://doshisha.repo.nii.ac.jp/record/28861/files/k1215.pdf https://doshisha.repo.nii.ac.jp/record/28861/files/zk1215.pdf https://doi.org/10.14988/00028853 https://doshisha.repo.nii.ac.jp/records/28861 eng BD00905871 掲載刊行物所蔵情報へのリンク ／ Link to Contents https://doors.doshisha.ac.jp/opac/opac_link/bibid/BB13204503/?lang=0 open access
