Abstract

A pressure release device includes a movable pressure release wall that can be moved relative to a pressure release opening. The pressure release wall, by virtue of its position relative to the pressure release opening, controls the passability of the opening. A detent stop is arranged in a path of movement of the pressure release wall.

First claim

The invention claimed is:

1. A pressure release device, comprising:
a pressure release wall configured to control a passability of a pressure release opening, said pressure release wall being mounted for movement relative to said pressure release opening and said pressure release wall being deformable about a pivot point; and
a detent disposed in a motion path of said pressure release wall.

2. The pressure release device according to claim 1 , wherein said pressure release wall has a first pivot point, and wherein a second pivot point is disposed in said pressure release wall.

3. The pressure release device according to claim 1 , comprising at least one guide element for said pressure release wall disposed to support said detent.

4. The pressure release device according to claim 1 , wherein said detent at least partially straddles said pressure release opening.

5. The pressure release device according to claim 1 , wherein said detent has a substantially linear detent edge.

6. The pressure release device according to claim 1 , wherein said pressure release wall has a flap with a linear motion axis.

7. The pressure release device according to claim 6 , wherein said linear motion axis is a pivot axis of said flap.

8. The pressure release device according to claim 6 , wherein an electrical switchgear cabinet has an operator panel and said flap is mounted, for opening the pressure release device, to move in a direction of the operator panel.

9. An electrical cabinet, comprising the pressure release device according to claim 1 .

10. A method of operating a pressure release device, the method comprising:
providing a movable pressure release wall to control a passability of a pressure release opening with the pressure release wall;
wherein the pressure release wall is moved when an overload pressure arises;
wherein the pressure release wall impacts a detent; and
with the pressure release wall bearing against the detent, moving the pressure release wall onward at least in portions; and
with the pressure release wall abutting the detent, plastically deforming the pressure release wall.

11. The method according to claim 10 , which comprises plastically deforming the pressure release wall to secure the pressure release wall in a form-fitting manner on the detent.
