Embodiment Construction

[0024] exist figure 1 A first embodiment of a planar electrode arrangement according to the invention is shown in , which consists of a helically wound flat strip 1 which, with its rounded ends 2, forms the central region 3 of the electrode arrangement And then it is shaped in such a way that it forms mutually abutting helical turns 4 by which edge regions are delimited. The turns of the strip rest against each other via molded spacers 5 .

[0025] The strip 1 consists of a dielectric material and constitutes the dielectric of the electrode arrangement. exist figure 1 The side visible in is the placement side 6 on which the strip 1 is provided with a plurality of elevations 7 which, in the exemplary embodiment shown, are designed as round knobs. All elevations 7 have the same height and define with their upper sides a placement area for a (not shown) counter electrode which can be formed by the area to be treated if it is grounded, for example. The elevations 7 occupy only...

Abstract

The invention relates to a flexible flat electrode arrangement for a dielectrically limited gas discharge, comprising a central region (3), an edge region, and a flat electrode (14) which conducts a high-voltage potential and which is embedded in a flat dielectric that forms an upper face (10) and a contact face (6). The invention allows the active surface of the electrode arrangement to be matched to the size of a surface to be treated in that the flat dielectric is in the form of a flat strip (1) wound into a spiral at least in the edge region, and the electrode (14) is formed by at least one electric conductor which runs in the longitudinal direction of the wound strip (1) and which leads into an end surface (13) of the strip (1).

Description

technical field [0001] The invention relates to a flexible planar electrode arrangement for dielectric barrier gas discharges, which has a central region and edge regions and has planar electrodes conducting a high-voltage potential, which are embedded in a planar dielectric forming the upper side and the placement side . Background technique [0002] Dielectric barrier plasma discharges are used in a variety of applications. It is known from DE 195 32 105 C2 to treat, for example activate or clean, the surface of a three-dimensional workpiece. The oil layer can be reduced down to a minimum oil film by so-called barrier discharges. However, it is important here that a homogeneous treatment of the surface takes place. A homogeneous formation of the plasma is required for this, the idea being that the plasma discharge takes place in thin lines spaced apart from one another. This is problematic for irregularly three-dimensionally shaped surfaces. It is therefore proposed i...
