  • Patent number: 7884505
    Abstract: A dry-type high-voltage load system apparatus has a space-saving structure, which is resistant to chain breaking, arc discharge and vibration, and a method of preventing the chain breaking and the arc discharge for use with the system apparatus. The system apparatus includes a dry-type high-voltage load system circuit including a low-voltage bank formed of lower-capacity configuration banks which include three-phase resistor circuits which are low-voltage resistor circuit. A high-voltage bank includes lower-capacity configuration banks for a high-voltage resistor circuit formed of three-phase resistor circuits. The three-phase resistor circuits are connected to a high-voltage power generator in parallel and arein the form of a Y-connection of three resistor arrays so that an isolated and independent neutral point is unconnected to other neutral points. The three phase resistor circuits may also be in the form of a ?-connection.

  • Patent number: 7712583
    Abstract: Disclosed is a method and apparatus for controlling automatic lifting and lowering type platform that can correct the inclination of a mobile power generator and that can always maintain the level while carrying out automatic lifting and lowering of the generator. The apparatus includes vertical outer cases which are extended or withdrawn in the horizontal directions from or into both sides at both ends of the chassis ?; vertical inner cases which are inserted into the vertical outer cases and extended or withdrawn in the vertical directions; and an allotter which allots output to jacks so that inclination detected by an angle sensor can always be corrected.
