Abstract

A top head housing for a current transformer, mounted on top of an insulating column of the current transformer, and forming a chamber for windings of the current transformer, the top head housing being made of two parts fixed one to the other, and including two openings through each of which a conductor penetrates the chamber, the openings being symmetrically opposed with reference to a main vertical axis of the top head housing, wherein the two parts of the top head housing consist of two half shells including identical bodies.

First claim

What is claimed is:

1. A top head housing for a current transformer, which is to be mounted on top of an insulating column of the current transformer, and forming a chamber for windings of the current transformer, the top head housing comprising:
a top part and a bottom part fixed one to the other, comprising:
two openings through each of which a conductor penetrates the chamber, the two openings being symmetrically opposed with reference to a main vertical axis of the top head housing, wherein the two openings are located on opposite side portions of the top part and the bottom part, and wherein the top part and the bottom part of the top head housing consist of two half shells comprising identical hollow bodies and identical bases extruding outwards from the hollow bodies; and
two holes, a first hole of the two holes located at the base of the top part and a second hole of the two holes located at the base of the bottom part.

2. The top head housing according to claim 1 , wherein the top part and the bottom part each further comprise an end edge, and wherein the end edge of the top part contacts the end edge of the bottom part.

3. The top head housing according to claim 2 , wherein the end edge of the top part is symmetrical to the end edge of the bottom part, and wherein the end edge of the top part and the end edge of the bottom part are adjacent to the opposite side portions of the top head housing.

4. The top head housing according to claim 2 , wherein the end edge of the top part and the end edge of the bottom part are tilted.

5. The top head housing according to claim 2 , wherein the top part and the bottom part each comprise a flange extending radially, with respect to the main vertical axis of the top head housing, from the end edge of the hollow body of the top part and the end edge of the hollow body of the bottom part.

6. The top head housing according to claim 5 , wherein the top part and the bottom part are attached to each other at the flange of the top part and the flange of the bottom part.

7. The top head housing according to claim 5 , wherein each flange comprises an annular groove for receiving a gasket between the flange of the top part and the flange of the bottom part.

8. The top head housing according to claim 5 , comprising an external connector attached to the flange of the top part and the flange of the bottom part.

9. The top head housing according to claim 1 , wherein the hollow body of the top part and the hollow body of the bottom part each comprise at least one wall in which at least part of the two openings is formed.

10. The top head housing according to claim 1 , wherein the top part and the bottom part are each formed by molding.
