Abstract

A device support assembly for an electrical device, in particular a transformer or a power transformer, includes: a plurality of retaining units arranged on the device itself; and a support arrangement which has a plurality of load stabilizers. The electrical device is set down on the load stabilizers by the retaining units in an end position and/or rests and is arranged between the load stabilizers, at least in portions, after being set down.

First claim

The invention claimed is:

1. A device support assembly, comprising:
an electrical device;
a plurality of retaining units, each retaining unit comprising:
a vertical plate coupled to the electrical device; and
a horizontal plate coupled to the vertical plate, arranged perpendicular to the vertical plate, and height adjustable with respect to the electrical device; and

a support arrangement comprising a plurality of load stabilizers,
the plurality of retaining units configured to support the electrical device on the plurality of load stabilizers such that the electrical device is configured to at least partially rest on and be arranged between the plurality of load stabilizers, and
the horizontal plates of the retaining units configured to rest on the load stabilizers.

2. The device support assembly according to claim 1 , wherein the plurality of load stabilizers are arranged on a foundation, which bears a load of the electrical device.

3. The device support assembly according to claim 2 , further comprising at least one of an attenuating element, a vibration damper, an anti-vibration underlay arranged between at least one of the plurality of load stabilizers and the foundation, or between at least one of the plurality of load stabilizers and at least one of the plurality of retaining units.

4. The device support assembly according to claim 2 , wherein the foundation comprises a concrete foundation.

5. The device support assembly according to claim 1 , wherein the plurality of retaining units comprises at least four retaining units which are arranged on the electrical device.

6. The device support assembly according to claim 5 , wherein the at least four retaining units removably fastened to the electrical device.

7. The device support assembly according to claim 1 , wherein the vertical plate of each retaining unit comprises two parallel, vertical steel plates, and wherein the horizontal plate of each retaining unit comprises a horizontally aligned steel plate.

8. The device support assembly according to claim 1 , wherein the plurality of load stabilizers comprises four columnar support feet.

9. The device support assembly according to claim 1 , wherein the electrical device comprises a transformer or a power transformer.

10. The device support assembly according to claim 1 , wherein the vertical plates of the plurality of retaining units are parallel to each other.

11. The device support assembly according to claim 1 , wherein each retaining unit is vertically adjustable with respect to the electrical device.

12. A method for installing an electrical device using a device support assembly and a trailer, the method comprising:
bringing the electrical device to an installation location using the trailer, the load bed being raised on the trailer such that a plurality of retaining units are freely movable over a plurality of load stabilizers of a device support assembly at an installation location, each retaining unit comprising a vertical plate coupled to the electrical device and a horizontal plate coupled to the vertical plate and arranged perpendicular to the vertical plate;
moving the electrical device to the installation location to position and align the plurality retaining units over the plurality of load stabilizers;
adjusting a height of at least one retaining unit of the plurality of retaining units with respect to the electrical device;
lowering the load bed such that horizontal plates of the plurality of retaining units and the electrical device rest on the plurality of load stabilizers in the end position of the plurality of retaining units; and
further lowering the load bed until the load bed is horizontally movable with clearance under and away from the electrical device.

13. The method of claim 12 , wherein the electrical device comprises a transformer or a power transformer.

14. The method of claim 12 , wherein each of the plurality load stabilizers comprises a rest pillar.

15. The method of claim 12 , further comprising:
before lowering the load bed, adjusting a height of the horizontal plate of at least one of the plurality or retaining units.
