Title (EN) STATIONARY INDUCTION ELECTRIC DEVICE
(FR) DISPOSITIF ÉLECTRIQUE À INDUCTION STATIONNAIRE
(JA) 静止誘導電器
Abstract:
(EN) Provided is a stationary induction electric device that is capable of improving insulation performance with a small number of additional structures. This stationary induction electric device is provided with: an iron core 1; a low-voltage winding conductor 400 that is wound on the iron core; an insulator 3 that surrounds the low-voltage winding conductor; a high-voltage winding conductor 2 which is wound on the insulator and to which a voltage is applied from the outside; and a first shield conductor 5 wound adjacently to the inner peripheral surface of the insulator and a second shield conductor 4 wound adjacently to the outer peripheral surface of the insulator, wherein ends of the first and second shield conductors are electrically connected to parts of the high-voltage winding conductor.
(FR) L'invention concerne un dispositif électrique à induction stationnaire qui est capable d'améliorer les performances d'isolation avec un petit nombre de structures supplémentaires. Ce dispositif électrique à induction stationnaire comprend : un noyau de fer 1 ; un conducteur d'enroulement basse tension 400 qui est enroulé sur le noyau de fer ; un isolant 3 qui entoure le conducteur d'enroulement basse tension ; un conducteur d'enroulement haute tension 2 qui est enroulé sur l'isolant et auquel une tension est appliquée depuis l'extérieur ; et un premier blindage conducteur 5 enroulé de manière adjacente à la surface périphérique interne de l'isolant et un second blindage conducteur 4 enroulé de manière adjacente à la surface périphérique externe de l'isolant, les extrémités des premier et second blindages conducteurs étant électroconnectées à des parties du conducteur d'enroulement haute tension.
(JA) 少ない付加構造物で絶縁性能を向上可能な静止誘導電器を提供することである。鉄心1と、鉄心に巻回される低圧巻線導体400と、低圧巻線導体を取り囲む絶縁物3と、絶縁物に巻回される、外部から電圧が印加される高圧巻線導体2と、を有する静止誘導電器において、絶縁物の内周面に隣接して巻回された第1シールド導体5及び外周面に隣接して巻回された第2シールド導体4と、第1シールド導体及び第2シールド導体 の一端を高圧巻線導体の何れかの部位と電気的に接続する。
