    摘要: A spring operation device for use in a switchgear includes an interlock bar, attached at its one end to a lock plate and includes a switch-on electromagnet that has a plunger provided with a flange portion. The lock plate is pushed by a lock member that is attached to a four-joint link and the position of the lock plate is changed by being rotated. During an opening operation of a switching contact, the other end of the interlock bar is arranged above the flange portion to stop the forward movement of the plunger of the switch-on electromagnet so as to prevent a switch-on trigger from rotating. During a closing operation of the switching contact, the other end of the interlock bar is arranged at a position that does not stop the plunger of the switch-on electromagnet from moving forward so that the switch-on trigger is allowed to rotate.

    摘要: A power switching control device and a closing control method thereof that can suppress generation of a transient voltage or current that is possibly caused by a variation in a load-side voltage after interrupting a current are obtained. A circuit-breaker-gap-voltage estimate value at and after a present time is calculated based on a power-supply-side voltage estimate value and a load-side voltage estimate value at and after the present time, a target closing-time domain from a closing controllable time to a closing control limit time in which a circuit breaker can be closed at a timing when an absolute value of the circuit-breaker-gap-voltage estimate value falls within a preset allowable range is calculated based on this circuit-breaker-gap-voltage estimate value, and the closing controllable time is delayed by a preset delay time in a case of a subsequent closing phase of a second or later closing phase.

    摘要: An inrush current suppressing device includes a residual-magnetic-flux calculating unit configured to retain an interruption characteristic of a breaker and an attenuation characteristic of a magnetic flux that are estimated by measurement, analysis, or the like beforehand, and apply the attenuation characteristic to a magnetic flux value at the time of current interruption obtained based on the interruption characteristic of the breaker to calculate a residual magnetic flux value. The breaker is turned on in a power supply voltage phase in which the calculated residual magnetic flux value and a theoretical value of a steady magnetic flux match.

    摘要: A residual-magnetic-flux calculating unit includes a voltage-change-rate detecting unit that detects a transformer-voltage change rate from a phase voltage between a breaker and a transformer, a residual-magnetic-flux detecting unit that detects a residual magnetic flux remaining on the transformer based on the phase voltage, and a breaker-switching-state identifying unit that detects a switching state of the breaker. The residual-magnetic-flux calculating unit recalculates the residual magnetic flux based on the transformer-voltage change rate and a predetermined threshold while the breaker is in an open state.
