摘要： According to the embodiments, a direct-current interrupting device includes a mechanical breaker (2), a semiconductor breaker (3), and a commutation device (4). The mechanical breaker (2) comprises a mechanical contact (6) made by connecting a high-voltage contact and a current interrupting contact in series, and bushings (8) which are connected to a pressure vessel (5) equipotential to the ground potential and electrically connect the both ends of the mechanical contact (6) and a direct-current transmission system. The commutation device (4) is connected to at least the high-voltage contact of a high-voltage contact and a current interrupting contact in parallel, and is connected to the semiconductor breaker (3) in series. The direct-current interrupting device opens the path of the mechanical contact (6) when an accident occurs in the direct-current transmission system to make a semiconductor stack (31) in a current-carrying state, and make the current flowing through the mechanical breaker (2) temporarily zero by the commutation device (4), thereby transferring the accident current from the mechanical breaker (2) to the semiconductor breaker (3). The direct-current interrupting device sets the semiconductor stack (31) to a blocking state after the transference, thereby blocking the accident current.

摘要： A high-speed input device of an embodiment includes a contact point portion, a drive mechanism portion, and an impact buffer portion. The contact point portion includes a drive electrode and a counter electrode. The drive mechanism portion includes a driving portion and a drive side urging portion. The driving portion applies a driving force in a first direction approaching the counter electrode with respect to the drive electrode during an input operation. The drive side urging portion applies a return force in a second direction separating from the counter electrode with respect to the drive electrode. The impact buffer portion includes a counter side urging portion and a counter side stopper. The counter side urging portion applies a return force in a second direction contacting the drive electrode with respect to the counter electrode. The counter side stopper regulates the displacement of the counter electrode in the second direction while the drive electrode and the counter electrode are separated from each other in a steady state.
