Abstract

A bushing for gas-insulated switchgear has an electrical conductor, which has a longitudinal axis and which is embedded in an insulating material, and a coated electrode that is arranged coaxially spaced apart from the conductor and that is formed from a plurality of segments.

Claims (18)

1. A bushing for a switchgear, the bushing comprising:

an electrical conductor, which has a longitudinal axis and which is embedded in an insulating material coating the conductor; and

a coated electrode that is arranged coaxially to and spaced apart from the conductor and that has a first end and a second end, the coated electrode being embedded in the insulating material and being provided with at least one electrical terminal,

wherein the coated electrode has at least two interruptions extending in an axial direction from the first end up to the second end, forming at least two segments, and

the at least two segments are electrically insulated from one another and are provided with at least one terminal, respectively.

2. The bushing in accordance with claim 1 , wherein the switchgear is a medium-voltage switchgear.

3. The bushing in accordance with claim 1 , wherein the at least two segments are formed as half-shells.

4. The bushing in accordance with claim 1 , wherein at least one of the interruptions extends in a straight line.

5. The bushing in accordance with claim 4 , wherein all of the at least two interruptions extend in a straight line.

6. The bushing in accordance with claim 1 , wherein the coated electrode is configured as a flexible circuit board in which the at least two segments are arranged as conductor paths on an insulating carrier material.

7. The bushing in accordance with claim 1 , wherein the at least two segments are formed by a conductive plastic or a semiconductive plastic.

8. The bushing in accordance with claim 1 , wherein at least one of the at least two interruptions extends in a curved manner.

9. The bushing in accordance with claim 8 , wherein the at least one of the at least two interruptions extends in a helical manner.

10. The bushing in accordance with claim 1 , wherein the at least two segments overlap along an interruption.

11. The bushing in accordance with claim 1 , wherein at least two adjacent segments are provided with an outwardly arched beaded-over portion along an interruption.

12. The bushing in accordance with claim 1 , wherein the at least two segments extend in an axial direction over a length that corresponds at least to a diameter of the conductor.

13. The bushing in accordance with claim 1 , wherein sizes of insulating material surfaces of the at least two segments are different.

14. The bushing in accordance with claim 1 , wherein respectively one measurement device that measures a different physical quantity is connected to the at least one terminal.
