Abstract (en)

[origin: EP3640964A1] A direct-current circuit breaker according to an embodiment of the present invention has a mechanical switching part, a semiconductor switching part and a commutation device. The mechanical switching part has at least one mechanical switching unit and an insulating column which supports the at least one mechanical switching unit. The mechanical switching unit has at least one unitary switching part. The unitary switching part has a mechanical contact part, a sealed container, an operation rod and an operation mechanism. The mechanical contact part has a fixed contact and a movable contact. The mechanical contact part is electrically insulated from the ground. The sealed container encloses the mechanical contact part and an insulating gas. The sealed container is electrically insulated from the ground. The operation rod is connected to the movable contact. The operation rod extends from the inside of the sealed container towards the outside thereof. The operation mechanism is connected to the operation rod. The operation mechanism causes the movable contact and the fixed contact to be brought into contact with and separated from each other. The operation mechanism is provided at the same electric potential as that of the movable contact.
