Abstract

A device for compensating for vibration and/or material stress of a component of a high-voltage system filled with a viscous medium includes a piston and a housing. A first end piece of the piston may be coupled to the component of the system. A second end piece of the piston may be at least partly within the housing and enclosed thereby, enabling movement of the piston and the housing in opposite directions along an axis. The second end piece may be coupled to an inner wall of the housing by at least one spring. The piston and the housing are surrounded by the medium filling the system. A method and computer program product for computer-aided design of a device for compensating for vibration and/or material stress of a component of the system filled with a viscous medium are also provided.

First claim

The invention claimed is:

1. A high-voltage system comprising a device, the device including:
a piston and a housing for compensating for at least one of a vibration or a material stress of a component of the high-voltage system filled with a viscous medium;
said piston and said housing being movable in opposite directions along an axis;
said piston having a first end piece to be coupled to the component, and said piston having and a second end piece disposed at least partly within and enclosed by said housing;
said housing having an inner wall;
a spring coupling said second end piece of said piston to said inner wall of said housing; and
said piston and said housing configured to be disposed in the high-voltage system and surrounded by the medium filling the high-voltage system.

2. The high-voltage system according to claim 1 , wherein said housing has an outer wall to be coupled to a supporting structure of the high-voltage system.

3. The high-voltage system according to claim 1 , wherein at least one of said piston or said housing are configured in dependent on at least one of:
a property of the component of the high-voltage system, or
a property of the high-voltage system, or
surroundings of the high-voltage system, or
conditions of transport or mounting of the high-voltage system.

4. The high-voltage system according to claim 1 , wherein the viscous medium is an insulating liquid.

5. The high-voltage system according to claim 1 , wherein said housing has a plurality of inner walls, and said second end piece of said piston is spaced apart from at least one of said inner walls of said housing by a gap defining a specified minimum gap distance.

6. The high-voltage system according to claim 5 , wherein said minimum gap distance is defined in dependence on specified production tolerances of at least one of the component of the high-voltage system or the high-voltage system.

7. The high-voltage system according to claim 1 , wherein said housing has walls including said inner wall, and at least one of said walls of said housing has at least one passage for a flow of the medium into the housing or out of the housing.

8. The high-voltage system according to claim 1 , wherein said second end piece of said piston has at least one clearance.

9. The high-voltage system according to claim 1 , wherein said housing has a plurality of inner walls, and at least one of said inner walls of said housing has at least one clearance.

10. The high-voltage system according to claim 1 , wherein:
said housing has walls including said inner wall and said inner wall is one of a plurality of inner walls;
at least one of said walls of said housing has at least one passage for a flow of the medium into the housing or out of the housing;
said second end piece of said piston has at least one clearance;
at least one of said inner walls of said housing has at least one clearance; and
at least one of a number or a configuration or a position of said at least one clearance or said at least one passage is formed in dependence on a specified property of at least one of:
the high-voltage system, or
surroundings of the high-voltage system, or
conditions of transport or mounting of the high-voltage system.

11. The high-voltage system according to claim 1 , wherein said spring is at least one spring having a spring constant defined for compensating for at least one of a vibration or a material stress of the component in dependence on at least one of:
a property of the component of the high-voltage system, or
a property of the high-voltage system, or
surroundings of the high-voltage system, or
conditions of transport or mounting of the high-voltage system.

12. The high-voltage system according to claim 1 , wherein said spring is at least one spring, and said at least one spring includes at least one of a helical spring, a cup spring, a buffer spring or an annular spring.

13. The high-voltage system according to claim 1 , wherein said spring is at least one spring formed at least partly of glass-fiber reinforced plastic.
