遮断器用油圧操作装置の動作時間安定化に関する研究 / シャダンキヨウ ユアツ ソウサ ソウチ ノ ドウサ ジカン アンテイカ ニカンスル ケンキュウ山下 透, Tohru Yamashita 02 March 2017 (has links)
電力用遮断器の油圧操作装置において，油圧回路内の気泡が操作装置の動作に及ぼす悪影響を解消するために，新しい油圧回路方式である常時高圧安定回路方式を提案し，油圧回路内の流れおよび可動部の定式化と解析および実測を行った．本方式の動作特性と動作安定性，ピストンの制動特性，複数の油圧操作装置の駆動特性について検討し，本方式が有効かつ安定的に機能することを確認した．以上により，油圧操作装置の動作時間安定化技術を開発することができた． / We proposed and studied a hydraulic operation stabilizing system for a hydraulic operating device of a circuit breaker to eliminate the influence of air bubbles created in hydraulic fluid. We formulated the flow of hydraulic circuit and the motion of moving parts, which were numerically simulated and experimentally confirmed. We confirmed that this stabilizing system functioned effectively and stably through the investigation: operation characteristics and stability of the stabilizing system, braking characteristics of a piston-dashpot system and operation characteristics of two hydraulic operating devices. Based on the results, we could perform an engineering development for stabilizing operation time of the hydraulic operating device. / 博士(工学) / Doctor of Philosophy in Engineering / 同志社大学 / Doshisha University
