Abstract

Exemplary embodiments are directed to a test arrangement for testing surge voltage in electrical high voltage components with a surge voltage generator and a voltage distributor. The surge voltage generator and voltage distributor have a tower-like structure with a first and a second structure end. A rectangular container is connected to the first and second structure and includes a first and a second container end. At least one of the surge voltage generator and the voltage distributor are movable between a first substantially horizontal position inside the container and a substantially vertical position relative to the container. Each movement between the two positions involves a pivot motion about a rotational axis perpendicular to the longitudinal direction of the surge voltage generator.

Claims

1. A test arrangement for impulse voltage testing of electrical high-voltage components, comprising:

a cuboid container having first and second container ends;

an impulse voltage generator arranged in the container; and

a voltage divider arranged in the container,

wherein a structure of at least one of the impulse voltage generator and the voltage divider includes a tower having a first and a second structure end;

wherein at least one of the impulse voltage generator and the voltage divider can be moved between a first position, which is substantially horizontal, within the cuboid container, and a second position, which is substantially vertical, relative to the container, and

wherein movement between the vertical and horizontal positions includes a pivoting movement about a respective rotation axis transversely with respect to the longitudinal direction of the impulse voltage generator.

2. The test arrangement as claimed in claim 1, wherein the container is connected to a transport apparatus, which has wheels for support.

3. The test arrangement as claimed in claim 1, wherein the container has an internal area at its first end, that includes measurement apparatuses and/or evaluation apparatuses.

4. The test arrangement as claimed in claim 1, wherein the container is a transportable freight container that is bounded at least in places by walls or wall segments on each of its six sides.

5. The test arrangement as claimed in claim 4, wherein the freight container is a 40-foot freight container.

6. The test arrangement as claimed in claim 4, wherein the freight container is licensed in accordance with CSC.

7. The test arrangement as claimed in claim 1, wherein the impulse voltage generator and the container are connected through respective second ends by means of a rotating connection.

8. The test arrangement as claimed in claim 1, wherein a drive is provided for carrying out the pivoting movement.

9. The test arrangement as claimed in claim 1, wherein at least one step of the test, can be initiated by means of remote control.

10. The test arrangement as claimed in claim 1, wherein the container can be closed on an upper face by at least one movable cover.

11. The test arrangement as claimed in claim 10, wherein the impulse voltage generator and the voltage divider can be pivoted through an opening on the upper face of the container, wherein the opening results from movement of the cover to a limit position.

12. The test arrangement as claimed in claim 1, wherein the container is in each case bounded by at least one wall or wall segment at its second end on two side surfaces, wherein the at least one wall or wall segment can be moved between an open position and a closed position.

13. The test arrangement as claimed in claim 12, wherein the container is secured against tilting when in an open position by the at least one wall or wall segment.

14. The test arrangement as claimed in claim 1, wherein the impulse voltage generator is connected with at least one of a force fit and/or an interlock to an end wall of the second end of the container, and can be pivoted together with the end wall about the rotation axis.

15. The test arrangement as claimed in claim 1, wherein the voltage divider and the impulse voltage generator are connected through a movement apparatus that can be moved longitudinally and acts transversely with respect to respective parallel longitudinal axes of the voltage divider and the impulse voltage generator.

16. The test arrangement as claimed in claim 1, wherein the voltage divider is integrated within a supporting column of the impulse voltage generator, wherein the supporting column is formed from a plurality of insulating tubes which are arranged one behind the other along the structure.
