摘要： Provided are a DC power transmission system, a method, and a central server for the system capable of promptly, safely, and surely recovering a section where a fault is removed to a system when the fault occurs in a DC power transmission path. When an occurrence of a fault in a DC power transmission path formed by diverging into a multiple paths or converging a multiple paths is detected, first, a switch 6 is opened to disconnect a fault section 23 from the DC power transmission path, second, after the opening, one of the opened switches 6 is closed, third, after the one switch is closed, when the continuation of a fault is detected, the one closed switch 6 is opened again, and fourth, after the closing of the one switch 6, when no continuation of the fault is detected, all switches 6 opened to disconnect the fault section 23 from the DC power transmission path are returned to the ON status, thereby recovering the fault section.

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.

摘要： A gas-insulated switchgear which efficiently removes a remaining thermal gas to improve an insulation performance, and which is capable of easily accomplishing a current breaking duty required for a switchgear for a high voltage is provided. Inside a movable shield 23, with a piston 25a of an operation rod 25 being a partition wall, a compression chamber 30 and a suction chamber 31 are formed at a movable-contact-base-22 side and a movable-contact-21 side, respectively. The compression chamber 30 compresses an insulating gas in the compression chamber 30 by a movement of the piston 25a at the time of circuit opening operation, and sprays the insulating gas to an arc 40 produced between the fixed arcing contact 11 and the movable contact 21 via a communication hole 25c, a hollow portion 25b, and a ventilation hole 21a. The suction chamber 31 reduces the internal pressure by expanding an internal space by a movement of the piston 25a to suction a high-temperature gas due to the arc 40 through a clearance 31a between the movable contact 21 and the movable shield 23.

摘要： According to an embodiment, when a switchgear operating state is shifted from a close state to a cutoff state, a solenoid lever (36) is pushed and rotated by a plunger (38a) of an electromagnetic solenoid for cutoff (38) so that the solenoid lever (36) rotates in a direction opposite from the direction of the urging of a solenoid-lever return spring (37). A trigger roller pin (31a) and the solenoid lever (36) become disengaged from each other, an eccentric pin (32) and a trigger lever (31) are rotated by the urging force from a latch leading end (34c) become disengaged from each other, whereby a latch lever (12) is rotated by the released energy of a cutoff spring.

摘要： A power switch operating mechanism comprises: a series of external permanent magnets (31), a series of internal permanent magnets (32), an internal pipe (38), an external pipe (39), a three-phase coil (33), an output ring (34) and a power supply lead (33a). In the series of external permanent magnets (31), the magnets are juxtaposed in such a way that their magnetic poles are rotated by a maximum of 90° in each case. In the series of internal permanent magnets (32), the magnetic poles have magnetization vector radial components that are in the same direction as that of the series of external permanent magnets (31) and magnetization vector axial components that are in the opposite direction to that of the series of external permanent magnets (31). The series of external permanent magnets (31) and the series of internal permanent magnets (32) are fixed so that their magnetization vector radial components are in the same direction. The three-phase coil (33) is interposed with a fixed clearance between the series of external permanent magnets (31) and the series of internal permanent magnets (33).
