摘要： It is presented an insulation system (1-1) for a winding structure (11), the insulation system (1-1) comprising an insulating structure (2) providing flow paths (3-1, 5-1, 7-1) for a dielectric fluid (F), the insulation structure (2) being arranged to allow the dielectric fluid (F) to flow axially in a first main direction at a first end portion (11a) of the winding structure (11) and in a second main direction at a second end portion (11b) of the winding structure (11), the insulating structure (2) being further arranged such that the dielectric fluid (F) is able to flow locally in the insulating structure (2) essentially in level with the first end portion and the second end portion in directions having axial components (C3, C4) that are opposite to the first main direction and the second main direction, respectively. It is also presented an inductive device in which the insulation system (1-1) is arranged.
摘要翻译：提供一种用于绕组结构（11）的绝缘系统（1-1），所述绝缘系统（1-1）包括提供流路（3-1,5-1,7-1）的绝缘结构（2）对于介质流体（F），绝缘结构（2）被布置成允许电介质流体（F）在绕组结构（11）的第一端部（11a）处沿第一主方向轴向流动，并且第二主方向在绕组结构（11）的第二端部（11b）处，绝缘结构（2）进一步布置成使得介电流体（F）能够在绝缘结构（2）中局部流动，在与第一主方向和第二主方向相反的轴向分量（C3，C4）的方向上分别具有第一端部和第二端部。还提供了其中布置有绝缘系统（1-1）的感应装置。

摘要： The invention is related to an oil transformer (10), comprising a transformer vessel (12), a transformer core mounted (14) therein, at least one upright hollow cylindrical transformer coil (16, 18) with at least one axial cooling channel (34, 36) arranged around a limb (28) of the transformer core (14) and an oil chamber (20, 22, 60, 80, 90) arranged at an axial front side of the transformer coil (16, 18). At least one first opening (86, 87, 88) leading from the inner chamber (100) to the belonging front side of the transformer coil (16, 18) is foreseen and at least one second opening (70) is foreseen within the surrounding boundaries (64, 66, 94, 96) of the oil chamber (20, 22, 60, 80, 90). The oil chamber (20, 22, 60, 80, 90) is an under-pressure chamber, wherein the at least one first opening (86, 87, 88) is an inlet port and the at least one second opening (70) is an outlet (78) port.
摘要翻译：本发明涉及一种油变压器（10），其包括变压器容器（12），安装在其中的变压器芯（14），至少一个直立的空心圆柱形变压器线圈（16,18），其具有至少一个轴向冷却通道（14）的臂（28）周围布置的变压器线圈（16,18,34,36）和布置在变压器线圈（16,18）的轴向前侧处的油室（20,22,60,80,90）。至少一个从内室（100）通向变压器线圈（16,18）的相应前侧的第一开口（86,87,88）被预见并且至少一个第二开口（70）被预见在周围油室（20,22,60,80,90）的边界（64,66,94,96）。所述油室（20,22,60,80,90）是负压室，其中所述至少一个第一开口（86,87,88）是入口端口并且所述至少一个第二开口（70）是一个出口（78）端口。
