  • Switching apparatus
    Patent number: 6624374
    Abstract: A switching apparatus for multiphase electric power includes switching units corresponding to different phases. Each switching unit includes an operating mechanism having a movable coil disposed between two fixed coils, and a switch portion having a movable contact operatively connected to the movable coil. A separate power supply may be provided for each switching unit to permit individual control of the different phases.
    Type: Grant
    Filed: May 10, 2001
    Date of Patent: September 23, 2003
    Assignee: Mitsubishi Denki Kabushiki Kaisha
    Inventors: Kenichi Koyama, Toyomi Ooshige, Hiroyuki Sasao, Hiroyuki Akita, Yukimori Kishida, Mitsuru Tsukima, Toshie Takeuchi
  • Switching apparatus
    Patent number: 6611413
    Abstract: A switching device includes a pair of fixed coils and a pair of movable coils, with one pair being disposed between the other pair. Two of the coils may be connected back to back on opposite sides of a support plate to increase the stiffness of the coils and reduce damage due to impact between the fixed and movable coils. The coils include two sets of coils, each set including one of the fixed coils and one of the movable coils. The coil sets can be driven simultaneously or at different times to effect contact opening and closing.

  • Switching device
    Patent number: 6580345
    Abstract: A switching device includes a movable coil which is reinforced by a stiffener to increase the resistance of the movable coil to bending moments. The stiffener may include a nonmagnetic case which surrounds the movable coil. Alternatively or in addition, it may include a resin or other material encapsulating the movable coil.
