Abstract
(EN)
In an insulation tube, a longitudinal-section shape of a side wall is arched, allowing its creepage distance to be made longer relative to a simple cylindrical insulation tube member, without increasing its axial length (spatial distance between two conductive members), thereby allowing an insulation withstand voltage characteristic against shunt current etc. to be improved. Furthermore, heat absorption on an arched surface of an inner periphery of the side wall, and heat dissipation on an arched surface of an outer periphery of the side wall are respectively promoted since surface areas of the arched surfaces are increased.
(FR)
Dans un tube d'isolation, une forme à section longitudinale d'une paroi latérale est arquée, permettant à sa ligne de fuite d'être rendue plus longue par rapport à un élément de tube d'isolation cylindrique simple, sans augmenter sa longueur axiale (distance spatiale entre deux éléments conducteurs), permettant ainsi à une caractéristique de tension de tenue à l'isolation vis-à-vis un courant de dérivation, etc., d'être améliorée. De plus, une absorption de chaleur sur une surface arquée d'une périphérie interne de la paroi latérale, et une dissipation de chaleur sur une surface arquée d'une périphérie externe de la paroi latérale sont respectivement favorisées étant donné que des zones de surface des surfaces arquées sont augmentées.
(JA)
 絶縁筒において、側壁の縦断面形状をアーチ状にしたことにより、単なる筒状の絶縁性部材と比較して、軸方向の長さ(両導電性部材間の空間距離)を長くすることなく、沿面距離を長くすることができ、分流電流等に対する絶縁耐電圧特性が高められる。また、前記のアーチ面において表面積が大きくなり、側壁内周面側のアーチ面では吸熱し易くなり、側壁外周面側のアーチ面では放熱し易くなる。
