Embodiment Construction

[0037] First, for example for figure 1 , figure 2 and image 3 Explain the construction and mode of operation of compressed gas circuit breakers. here, in figure 1 , figure 2 and image 3 The same reference numerals are used in each of the same type of construction parts, and only for details that differ from each other, alternative reference numerals are used.

[0038] Common to all three figures is that the axis of symmetry 2 divides the figure into a first half and a second half. The drawings each show the switched state of the compressed gas circuit breaker in the first half of the figure and the switched state of the compressed gas circuit breaker in the second half of the figure.

[0039] figure 1 A cross-section of a compressed gas circuit breaker is shown in the cross-sectional view. The compressed gas circuit breaker has an encapsulation housing 1 . The encapsulation housing 1 is here substantially tubular and oriented coaxially to the axis of symmetry 2 . ...

Abstract

A circuit breaker includes a first contact and a second contact. An electric arc zone is disposed between the contacts. A feed channel opens into the electric arc zone, connecting the electric arc zone to a hot gas reservoir volume. The hot gas reservoir volume, in turn, is connected to a compression volume. An outflow opening is disposed in a wall of the compression volume. The outflow opening is permanently open, at least in a contacting state of the contacts.

Description

technical field [0001] The invention relates to a compressed gas circuit breaker, said switch having an arc zone arranged between a first contact and a second contact, said arc zone being connected via a supply channel to a hot gas storage volume, and the hot gas storage volume in turn connected to the variable-volume compression volume via an overflow channel; and having a wall delimiting the compression volume with at least one outflow opening. Background technique [0002] Such a compressed gas circuit breaker is described, for example, in the utility model DE20015563U1. Such a compressed gas circuit breaker has a first contact and a second contact, between which the arc zone extends. Guidance of the arc is provided within the arc zone. The arc zone is in turn connected via a supply channel to the hot gas storage volume, wherein a variable-volume compression volume is connected to the hot gas storage volume. The hot gas storage volume and the compression volume are con...
