| Zusammenfassung: | This gas circuit breaker has a sealed container, a first contactor part and a second contactor part, an operation mechanism, an insulating nozzle, a pressure accumulating means, and an electric field shield. The first contactor part and the second contactor part are brought into contact with each other in a closed electrode state and separated from each other in an open electrode state. The insulating nozzle is displaced in conjunction with the first contactor part during the separation process of the first contactor part and the second contactor part. The insulating nozzle surrounds an arc discharge arcing between the first contactor part and the second contactor part. The electric field shield is attached to the insulating nozzle. The electric field shield has a floating potential during at least a portion of the separation process. The electric shield is electrically connected to the second contactor part and has the same potential as the second contactor part in a completely open electrode state in which the first contactor part and the second contactor part are completely separated from each other. |
