Abstract
In a high-voltage power breaker having two rated current contact pieces and two arc contact pieces as well as an insulating nozzle, a filling body is provided, which is mounted on this insulating nozzle, surrounds the insulating nozzle in an annular shape and is composed of an electrically insulating material having a high dielectric constant, in order to influence the electric field in the isolating gap.
Claims8
A high-voltage power breaker, comprising:
- a first and a second rated current contact piece which are coaxially opposite one another;
- and
- a first and a second arc contact piece which are coaxially opposite one another, wherein
- at least the first rated current contact piece and the first arc contact piece associated therewith can be driven, and
- the first arc contact piece is connected to an insulating nozzle to blow out an arc which is struck between the two arc contact pieces, which insulating nozzle projects, at least partially in the disconnected state, into the isolating gap between the first rated current contact piece and the first arc contact piece and between the second rated current contact piece and the second arc contact piece,
- the insulating nozzle has an annular filling body, which is removably attached on its outer circumference and is composed of an insulating material having a dielectric constant.
