Abstract:
1. An arrangement of oil transformer insulation modules, the arrangement including a first oil transformation module comprising: at least a first flat layer and a second layer adjacent and substantially parallel to the first layer, wherein the first and second layers include planar first insulation material; a third layer arranged between the first and second layers, wherein the third layer includes planar second insulation material, has lateral edges, and is corrugated such that all cavities formed by the corrugated form can be flooded with a liquid via the lateral edges, wherein at least one lateral edge of the corrugated third layer is offset inwardly relative to the adjoining layers, such that a first groove with a first groove cavity is formed, the first groove in the corrugated third layer corresponding to a second groove having a second groove cavity formed in at least one other second oil transformer insulation module for joining to the second oil transformer module at the first and second groove cavities, wherein the first and second layers of insulation material are connected to and spaced apart from the third layer, wherein the corrugated third layer is homogenous and has a size corresponding to a respective size of the adjacent first and second layers, and wherein the first groove of the oil transformer module and the second groove of the second oil transformer module are arranged alongside one another on a groove side, a common groove cavity is formed by the first and second grooves adjoining one another, and the first and second oil transformer insulation modules are connected to one another by a third oil transformer insulation module, which is adapted in its form to the common groove cavity and is arranged in the common groove cavity.
