Abstract

The embodiments relate to a test configuration for an impulse voltage test of electric high-voltage components with a lightning generator. The lightning generator can be moved between a first horizontal position within a cuboid container, and a vertical position relative to the container. A movement between the two positions includes a pivoting movement about a rotational axis. The proofing movement is transverse to the longitudinal direction of the lightning generator. The container can be closed at the top by at least one moveable cover.

Claims

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

a cuboid container having a first and a second container end and at least one movable cover on an upper face; and

an impulse voltage generator that is a tower-like structure,

wherein the impulse voltage generator is movable between a substantially horizontal position within the cuboid container, and a substantially vertical position relative to the container,

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

wherein the container is closable on its upper face by the at least one movable cover.

2. The test arrangement as claimed in claim 1, comprising:

at least one surge arrestor,

wherein the at least one surge arrester can be pivoted together with the high-voltage generator between a substantially horizontal position within the container and a substantially vertical position.

3. The test arrangement as claimed in claim 2, wherein the surge arrester has at least one spark gap.

4. The test arrangement as claimed in claim 2, wherein the surge arrester has at least one semiconductor element.

5. The test arrangement as claimed in claim 2, wherein the surge arrester is arranged in the interior of the structure of the impulse voltage generator.

6. The test arrangement as claimed in claim 2, wherein the surge arrester is integrated in the tower-like structure of the impulse voltage generator.

7. The test arrangement as claimed in claim 2, wherein the surge arrester is arranged outside the tower-like structure, of the impulse voltage generator and is aligned parallel to it.

8. The test arrangement as claimed in claim 7, wherein the surge arrester and the impulse voltage generator are connected through a variable-length movement apparatus which acts transversely with respect to their parallel longitudinal axes.

9. The test arrangement as claimed in claim 1, wherein a voltage divider is pivotable together with the impulse voltage generator between a substantially horizontal position within the container and a substantially vertical position.

10. The test arrangement as claimed in claim 9, wherein the voltage divider and the impulse voltage generator are connected through a variable-length movement apparatus which acts transversely with respect to respective parallel longitudinal axes of the voltage divider and the impulse generator.

11. The test arrangement as claimed in claim 1, wherein the container is a standard freight container.
