Abstract

A high-voltage feed-through contains a securing flange for securing the high-voltage feed-through to a wall. The securing flange contains a retaining part and a moving part, wherein the moving part is mounted relative to the retaining part such that it can rotate in relation to a longitudinal direction of the high-voltage feed-through. An electrical device contains a fluid-tight housing and the high-voltage feed-through. A device connection part is provided for receiving and contacting the high-voltage feed-through.

First claim

The invention claimed is:

1. A high-voltage feed-through, comprising:
an attachment flange for attaching the high-voltage feed-through to a wall, said attachment flange having a holding part and a movable part, wherein said movable part is mounted so as to be able to rotate relative to said holding part about a longitudinal axis of the high-voltage feed-through defined by an inner conductor that extends along said longitudinal axis.

2. The high-voltage feed-through according to claim 1 , further comprising an outer housing, said holding part is fixed with respect to said outer housing of the high-voltage feed-through.

3. The high-voltage feed-through according to claim 1 , wherein said movable part is a rotating ring that is disposed in a concentric manner about said holding part.

4. The high-voltage feed-through according to claim 3 , wherein:
said holding part has an outer guide groove formed therein; and
said rotating ring has an inner face and on said inner face a protrusion is disposed that engages in said outer guide groove of said holding part.

5. The high-voltage feed-through according to claim 4 , wherein said holding part is configured at least in two pieces including a first and a second annular element, wherein said first annular element has a first outer indentation formed therein and said second annular element has a second outer indentation formed therein, wherein after said first and second annular elements have been brought together said first and second outer indentations form said outer guide groove.

6. The high-voltage feed-through according to claim 1 , further comprising:
a high-voltage connection;
a mating section configured so as to plug the high-voltage feed-through into a device connection part of an electrical device, said mating section having an outer coating of a flexible insulating coating material; and
said inner conductor extending in a longitudinal direction between said high-voltage connection and said mating section of said high-voltage feed-through.

7. The high-voltage feed-through according to claim 1 , further comprising an insulating body having field-controlling control inserts that are separated from one another by insulating layers, and wherein said field-controlling control inserts are disposed in a concentric manner around said inner conductor.

8. The high-voltage feed-through according to claim 7 , wherein said insulating body contains a hardened resin.

9. An electrical device, comprising:
a fluid-tight housing;
a high-voltage feed-through having an attachment flange, said attachment flange having a holding part and a movable part, wherein said movable part is mounted so as to be able to rotate relative to said holding part to about a longitudinal axis of said high-voltage feed-through defined by an inner conductor that extends along said longitudinal axis; and
a device connection part receiving and contacting said high-voltage feed-through.

10. The electrical device according to claim 9 , wherein:
said device connection part has an attachment section, said device connection part is attached by means of said attachment section to said fluid-tight housing;
said device connection part has a hollow receiving section extending from an electrically non-conductive insulating material into said fluid-tight housing; and
said device connection part has a metal contact part disposed on a closed tapering end region, said metal contact part extending through said electrically non- conductive insulating material of said hollow receiving section or increasing a length of said hollow receiving section towards the closed tapering end region.

11. The electrical device according to claim 10 , further comprising a current connection line extending within said fluid-tight housing, said metal contact part is connected to a convertor winding via said current connection line.

12. The electrical device according to claim 11 , wherein said current connection line is equipped with a current sensor.

13. A method for producing an electrical device having a fluid-tight housing and a device connection part so as to receive and contact a high-voltage feed-through, the high-voltage feed-through having an attachment flange for attaching the high-voltage feed-through to a wall, the attachment flange having a holding part and a movable part, wherein the movable part is mounted so as to be able to rotate relative to the holding part about a longitudinal axis of the high-voltage feed-through defined by an inner conductor that extends along said longitudinal axis, the method comprises the steps of;
inserting the high-voltage feed-through into the device connection part; and
rotating the movable part of the attachment flange of the high-voltage feed-through about the longitudinal axis of the high-voltage feed-through so as to align attachment elements of the high-voltage feed-through with respect to attachment elements of the device connection part.
