| 摘要 |
The invention relates to a high-voltage power circuit breaker comprising two nominal current contact pieces (1, 2), two arc contact pieces (3, 4), and an insulating nozzle (5) on which a filling body (12, 27) is provided. Said filling body encloses the insulating nozzle (5) in an annular manner and is comprised of an electrically insulating material with a high dielectric constant in order to influence the electric field in the isolating distance.
