Problems solved by technology

In order to ensure sufficient bursting strength, the size of the sheet flange used is larger
On the one hand, more material needs to be used due to the larger dimensions of the segment flange, and on the other hand, the circumference of the closed housing is increased due to the radially surrounding segment flange
Especially when relatively slender closure housings are used, these should be arranged directly adjacent to each other, which results in an increased occupied area

Embodiment Construction

[0038] FIG. 1 shows a sectional view of a gas-tight enclosing housing 1 of an electrical switching device 2 . The switching device 2 has a circuit breaker unit comprising first and second disconnection bays 3 , 4 which are connected in series with each other. Each disconnecting space 3 , 4 is designed, for example, as a breaking space acting according to the automatic gas pressurization principle. Examples of this are the patent documents US6177643B1 and US6271494B1, which describe the design of the disconnecting gap with relatively movable arc contacts and rated current contacts and also describe insulating material nozzles. The content of the aforementioned patent documents is a part of the present application.

[0039] The closed casing 1 is filled with an electronegative gas inside it, such as sulfur hexafluoride, nitrogen or a mixture of gases. The gas is subjected to a pressure greater than atmospheric pressure in order to increase its compressive strength. During swi...

Abstract

A capsule housing has at least three housing sections, extends along an axis, and has a substantially tubular-shaped frame. The housing sections are connected together on the front side thereof and they surround a receiving chamber on the inside. The inside has an electric circuit device. The receiving chamber has a smaller transversal cross-section than the respective cross-section in the region of the second and the third housing section in the region of the first housing section which connects the second and the third housing sections.

Description

technical field [0001] The invention relates to a gas-tight closed housing having at least three housing parts extending substantially tubularly along an axis, a first housing part of which is flanged between a second and a third housing part , wherein each housing part defines a pressure-resistant accommodating cavity for the electrical switching device. Background technique [0002] A closure housing of this type is known, for example, from patent application DE 43 20 906 A1. In the disclosed closure housing, the three housing parts are each flanged to one another at the end faces. The three housing parts are constructed similarly. This reduces the number of required basic shapes. The housing parts each have a radially outwardly shaped flat flange on the end side. The segment flanges are pressed against each other via corresponding connecting pieces in order to form an essentially tubular extending gas-tight closure housing. [0003] The structural volume of a switchi...
