For this purpose, the AC power souree of variabl form factor and variable frequency was made for trial, using an inverter, a filter and a phase-shifter. The author has measured the iron losses of Si-steel plate (JIS-S09F) 1.83kg by Epetein Set, changing the frequency and form factor of the output power of this equipment.","subitem_description_type":"Abstract"},{"subitem_description":"Inverter，Filter，Phase-Shifterを試作し，これ等を組み合せて可変波形率，可変周波数の交流電源を試作したので，この電源を用いて鉄損を測定した。\n試験器には小型Epstein試験装置を用い，波形率の測定には実効値電圧計および平均値電圧計の指示の比より算出して求め，これを試験器に供給した。\n試料には，JIS-S09F(T-90)，熱間圧延ケイ素鋼板，厚さ0.35[mm]のものを，3cmx28cmの短冊形に切ったもの1.83[kg]を用いた。\n本稿中の図-1は電源装置を，また，同じく本稿中の図-2はEpstein試験装置の接続図を示したものである。\nInverterのSCR用gate信号の周波数を変えて，電源周波数を制御し，また移械器および電圧調整器によって波形率を制御したものである。\nEpstein試験装置には特に試料挿入コイルの前後に切替開閉器S_2，S_3を取り付けた。\nその理由は従来の試験方法は電力計により回路の全消費電力を一旦測定し，つぎに，回路に接続されていた計器の内部抵抗を測定し，こがより計器による電力損失を計算し，もとの回路会体の消費電力より差し引き，残りを鉄損として計算した。\nこの方法はいちいち計器の損失を計算しなければならず，実際実験してみるとなかなか面倒なことである。\nそこで筆者は特に切替開閉器を試料挿入コイルの前後に設け，S_1，S_2を最初①側に閉じ普通と同じように回路全体の消費電力を測定し，つぎに，S_1, S__2を②側に閉じ試料挿入コイルを回路より切りはなし，試料以外の回路損失を再び電カ計にて測定した。\nただしこの時，幾分実効電圧Eが上昇するので実効電圧計Vを前に測定した時の電圧に合せるように電源電圧を多少調整しなければならない。\nこのようにすればいちいち計器の損失を計算する手数がなく測定能率を上げることが出来た。\nしかも精度は計器損失を計算より出した値と殆んど変らない程正確であった。\nつぎに筆者は本稿中の図-2のようにEpstein試験器の二次側にCRの積分回路を接続し，二次誘導起電力の積分電圧e'をシンクロスコープのY軸に，また一次側にはHコイルに直列に低抵抗rを接続し，その両端子をシンクロスコープのX軸に加えた。\nこのようにしてシンクロスコープに履歴環線を描がかしめ，そのループ面積より鉄損を計算し，シンクロスコープによる直視法と，エプスタイン装置による電力計法とを比較したものである。","subitem_description_type":"Abstract"}]},"item_3_description_40":{"attribute_name":"資源タイプ(DSpace)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_3_description_6":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"富山大学工学部紀要，20","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55833","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OKADA, Kumeji"}]}]},"item_3_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15099/00004015","subitem_identifier_reg_type":"JaLC"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"富山大学工学部"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00175872","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03871339","subitem_source_identifier_type":"ISSN"}]},"item_3_subject_22":{"attribute_name":"国立国会図書館分類","attribute_value_mlt":[{"subitem_subject":"ZM2","subitem_subject_scheme":"NDLC"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"岡田, 粂ニ"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-16"}],"displaytype":"detail","filename":"Kokiyo_20_01_Page001to007.pdf","filesize":[{"value":"9.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Kokiyo_20_01_Page001to007.pdf","url":"https://toyama.repo.nii.ac.jp/record/4021/files/Kokiyo_20_01_Page001to007.pdf"},"version_id":"a7298c54-c7ef-4695-a0a5-6b2eec3ae80c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"鉄損","subitem_subject_scheme":"Other"},{"subitem_subject":"波形率","subitem_subject_scheme":"Other"},{"subitem_subject":"可変波形率","subitem_subject_scheme":"Other"},{"subitem_subject":"可変周波数","subitem_subject_scheme":"Other"},{"subitem_subject":"交流電源","subitem_subject_scheme":"Other"},{"subitem_subject":"実効値電圧計","subitem_subject_scheme":"Other"},{"subitem_subject":"平均値電圧計","subitem_subject_scheme":"Other"},{"subitem_subject":"Inverter","subitem_subject_scheme":"Other"},{"subitem_subject":"Filter","subitem_subject_scheme":"Other"},{"subitem_subject":"Phase-Shifter","subitem_subject_scheme":"Other"},{"subitem_subject":"エプスタイン試験器","subitem_subject_scheme":"Other"},{"subitem_subject":"交流磁化曲線","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"鉄損と波形率の関係について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"鉄損と波形率の関係について"}]},"item_type_id":"3","owner":"3","path":["580"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-09-25"},"publish_date":"2012-09-25","publish_status":"0","recid":"4021","relation_version_is_last":true,"title":["鉄損と波形率の関係について"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-25T15:12:54.670094+00:00"}
