摘要： A direct current circuit breaker (1) includes a first breaking unit (3) and a second breaking unit (4). The first breaking unit (3) includes: a first circuit breaker inserted in a direct current line (2); and a resonance circuit unit (6) that generates a resonance current. The first breaking unit (3) forms a current zero point by superimposing the resonance current on a direct current flowing through the direct current line (2), and breaks the direct current by opening the first circuit breaker. The second breaking unit (4) includes a semiconductor element (15), allows the direct current to flow when energization of the semiconductor element (15) is ON, and breaks the direct current by switching energization of the semiconductor element (15) from ON to OFF.

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： To provide a phase control switchgear that can suppress generation of energizing inrush currents associated with a closing operation of a neutral-ungrounded or neutral-noneffectively-grounded no-load three-phase transformer. A phase having a largest absolute value of a residual magnetic flux is detected and designated as a first switch-on-phase, and an arbitrary phase of remaining phases is designated as a second switch-on-phase, after the first switch-on-phase is switched on, and after the second switch-on-phase is switched on, a remaining phase is designated as a third switch-on-phase. A phase in which a magnetic flux error between a load-side magnetic flux and a power-source-side magnetic flux due to mechanical operating variations of the three-phase switchgear is smaller, among two magnetic-flux matching phases in which a polarity and a size of the load-side magnetic flux match with those of the power-source-side magnetic flux in each switch-on-phase in one cycle, is designated as a target switch-on-phase in each switch-on-phase, for each of the phases, thereby switching on each phase individually in each target switch-on-phase.

摘要： A breaker-phase-control switching system according to one embodiment includes a merging unit (21) for transmitting waveform data of an electric quantity added with time information, a superordinate unit (22) for transmitting a close command or an open command for a circuit-breaker (31), and a circuit-breaker control unit (1) for electrically conducting a close coil (33) or a trip coil (34) of the circuit-breaker. The circuit-breaker control unit (1) includes a waveform-zero-point-calculation processing unit (7) for calculating a current phase, based on absolute time kept by an internal clock and waveform data, and a predicted-breaker-operating-time-calculation processing unit (8) for predicting a predicted operating time. Further, a command-output-timing-determination processing unit (9) is included which determines a timing for electrically conducting a coil from the absolute time, a preset target phase, a current phase, and a predicted operating time.
