Embodiment Construction

[0015] exist figure 1 The structure or formation of the interruption unit 2 with the vacuum interrupter 4 and the insulating housing 6 is shown in . In the leftmost illustration according to a, a vacuum interrupter 4 is shown which has a structural material 22 which surrounds a vacuum chamber 28 . Two switching contacts 26 are shown schematically in the vacuum chamber 28 , at least one of which is movable in translation along the switching axis 20 . Here, the outer configuration of the vacuum interrupter 4 is to be understood purely schematically, the structural material 22 usually consisting of an insulating ceramic material or comprising this insulating ceramic material generally only representing a part of the housing of the vacuum interrupter 4 . In particular in the region of the movement of the switching contact 26 along the switching axis 20 , the vacuum interrupter 4 is delimited on the outside by a metallic outer material.

Abstract

The invention relates to an interruption unit comprising a vacuum switching tube (4) and an insulating housing (6), the insulating housing (6) having an inner surface (8) and the vacuum switching tube (4) being at least partially bounded by an electrically insulating structural material (22), the structural material having an outer surface (10) and the insulating housing (6) at least partially surrounding the vacuum switching tube (4), the inner surface (10) of the insulating housing (6) and the outer surface (10) of the vacuum switching tube (4) are separated by an adhesive layer (12) in the ready-to-operate state of the interrupting unit (2), characterized in that both the inner surface (8) and the outer surface (10) are at least partially provided with an electrically conductive layer (14, 16), the vacuum switching tube (4) and the insulating housing (6) are arranged in such a way that in a boundary region (18) between the vacuum switching tube (4) and the insulating housing (6), the following layers are aligned radially outward from the switching axis (20): a structural material (22) of the vacuum switching tube, an outer surface (10) of the structural material (22), an electrically conductive layer (16) on the outer surface (10) of the structural material (22), an adhesive layer (12), an electrically conductive layer (14) on the insulating housing (6), and an inner surface (8) of the insulating housing, and a volumetric material (24) of the insulating housing (6).

Description

technical field [0001] The invention relates to an interruption unit according to the preamble of claim 1 . Background technique [0002] In order to avoid the climate-damaging sulfur hexafluoride, modern interrupting units are firstly filled with an alternative insulating gas, or a combination of a vacuum interrupter and an air insulation surrounding the vacuum interrupter functions. In the second described case, the usual design is such that the vacuum interrupter is in turn arranged in a further closed space in which clean air or another air-like gas mixture is present. In order to also increase the insulating capacity of this arrangement, it is expedient if the vacuum interrupter, which is at least partially formed in the outer circumference by an insulating material, for example insulating ceramic, is surrounded by a further insulating housing, which in particular consists of a plastic substrate , Such as epoxy resin formation. The insulating housing is therefore arra...
