Embodiment Construction

[0016] figure 1 Shown is a sheet metal 1 for the production of a container part of a sealed switchgear, which is rolled into a cylindrical tube 2 in a first method step, which is welded at butt edges 3 . At the first end 4 a flange 5 is then formed by deflection. For this, the cylindrical tube 2 is fixed in a rotating device and rotated about its central axis. Two rollers, which likewise rotate about their axes, are arranged on the cylindrical tube 2 in such a way that one of the two rollers rests against the outside and the other against the inside of the cylindrical tube 2 . The two rollers are arranged so as to be pivotable about a common point of rotation and are then pivoted outwards by 90°, so that a bead 5 is formed on the first end 4 of the cylindrical tube 2 . The thickness and the contour of the flange 5 can be varied here by repeated repetitions or by correspondingly changing the contours of the two rollers, so that a material-reinforced flange can also be formed ...

Abstract

The invention relates to a method for manufacturing a container component of a sealing type switch device, and a switch device. According to the invention, a method for manufacturing container components (6,20,21) of a sealing typoe switch device is provided. The method requires low cost. Pressure-bearing capability of teh container components are remainded; the method comprises structuring a cylindrical pipe (2,12) via welding between a rolling sheet (1,7) and abutted-sides (3,13) of the rolling sheet (1,7), and bending a flange (5,16,17) on at least one pipe end part (4) of the cylindrical pipe (2,12).

Description

technical field [0001] The invention relates to a method for producing a container part for a sealed switchgear. Background technique [0002] In methods known from the prior art for manufacturing vessel parts of sealed switchgear, such as gas-insulated medium-voltage switchgear filled with SF6 as Sealed switchgear for power distribution in the high and high voltage field consists of such cast containers. Typically, aluminum is used as a material for this. Such a hermetic switchgear consisting of such an aluminum container is not only material-intensive but also expensive. Contents of the invention [0003] The technical problem addressed by the invention is to provide a cost-effective method for producing a container part of a sealed switchgear with an approximately constant pressure resistance. [0004] According to the invention, the above-mentioned technical problem is solved by a method for manufacturing a container part of a sealed switchgear comprising the follow...
