Abstract

A modular high voltage supply system has a mobile adapter transformer with a high-voltage output side and a low-voltage input side, electrical connecting input-terminals being foreseen at the mobile adapter transformer outer surface, a mobile container with a low voltage supply system, mounted stationarily therein, having a high current busbar and at least one electrical frequency converter connected thereto, electrical connecting output-terminals for the high current busbar being foreseen at an accessible the mobile container edge; and a modular interim busbar system, for temporary electrical connection of input- and output-terminals, having at least one interim busbar with at least one elongated busbar basic module mounted on a frame structure and respective resilient electrical connections on both busbar basic module ends forming an electrical connection to the input- and/or output-terminals and arranged such that a transmission of vibrations from the mobile adapter transformer to the mobile container is suppressed.

First claim

The invention claimed is:

1. A modular high voltage supply system, comprising:
a mobile adapter transformer including a high-voltage output side, a low-voltage input side, and electrical connecting input-terminals, configured for the low-voltage input-side, provided at an outer surface of the mobile adapter transformer;
a mobile container including a low voltage supply system mounted stationary therein, the low voltage supply system including a high current busbar and an electrical frequency converter connected thereto, electrical connecting output-terminals for the high current busbar being provided at an accessible edge of the mobile container;
a modular interim busbar system configured for temporary electrical connection of the input- and output-terminals,
wherein the modular interim busbar system includes an interim busbar including an elongated busbar basic module, mounted on a frame structure, and a respective resilient electrical connection on both ends of the busbar basic module which form an electrical connection to the input- and/or output-terminals and which are arranged such that a transmission of vibrations from the mobile adapter transformer to the mobile container is suppressed,
wherein the resilient electrical connection includes a first and a second resilient elongated plate-like clamping element,
wherein the first and second resilient elongated plate-like clamping elements are arranged opposed to each other in a clamping distance,
wherein the first and second resilient elongated plate-like clamping elements are an electrical active part of an interim busbar,
wherein both ends of the opposed clamping elements include a respective electrical contact section, between which a respective further electrical active section of the interim busbar is clamped.

2. The system of claim 1 , wherein the opposed elongated plate-like clamping elements are connected together using screws or bolts extending through the respective electrical contact sections and through the respective electrical active section of the interim busbar clamped inbetween.

3. The system of claim 1 , wherein the elongated plate-like clamping elements are made at least predominantly from copper or aluminum.

4. The system of claim 1 , wherein two or more neighbored clamping elements are arranged in parallel in the same plane instead of a single clamping element.

5. The system of claim 1 , wherein the modular interim busbar includes an electrical active elongated square-shaped hollow busbar section.

6. The system of claim 5 , wherein the input terminals of the mobile adapter transformer extend into the elongated square-shaped hollow busbar section in a form-locking manner.

7. The system of claim 6 , wherein the resilient electrical connection extends into the elongated square-shaped hollow busbar section in a form-locking manner.

8. The system of claim 6 , wherein the input terminals or the resilient electrical connection extending into the elongated square-shaped hollow busbar section are connected thereto using screws or bolts.

9. The system of claim 7 , wherein the elongated square-shaped hollow busbar section is made at least predominantly from aluminum.

10. The system of claim 1 , wherein the modular interim busbar system includes a first, second, and third interim busbar,
wherein the respective busbar basic modules are arranged within the frame structure in a horizontal and vertical distance each to each other.

11. The system of claim 1 , wherein the mobile container includes a cooling system.

12. The system of claim 1 , wherein the mobile container is a standard container according to CSC (Container Safety Convention) standard.
