  • Patent number: 8779634
    Abstract: A target closing phase determining circuit determines energization flux errors in respective phases and respective closing phases of a first phase, and determines a target closing phase of the first phase so as to minimize an evaluated value related to determined energization flux errors in the respective phases. Each of the energization flux errors is the maximum value of absolute values of center values of transformer fluxes generated in a static state after energization. The target closing phase determining circuit determines the energization flux errors based on residual flux values for the first to third phases of a three-phase power supply, respectively, a pre-arc characteristic and a closing time variation characteristic of a three-phase circuit breaker, a connection condition of windings of a three-phase transformer, to which the three-phase circuit breaker is connected, and voltage phase differences among the phases of the three-phase power supply.

  • Patent number: 8599899
    Abstract: An agitation device, a melting apparatus, and a melting method for improving melting efficiency of molten metal without contaminating the same. The agitation device is provided with a traveling magnetic field generating unit which is disposed outside a charging tank for storing molten metal and generates, inside the charging tank, a magnetic field that travels downward along the rear sidewall of the charging tank. A flow of the molten metal that rotates longitudinally about an axis approximately parallel to the surface of the molten metal is produced in the molten metal. By charging aluminum cutting chips into the molten metal in which the flow is produced, the aluminum cutting chips move with a downward flow of the molten metal, and are immersed in the molten metal. As a result, melting of the aluminum cutting chips can be accelerated.
