| 20100039212 | Dry-type high-voltage load system apparatus and method of preventing chain breaking and arc discharge for use therewith - 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 are in 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 Δ-connection. | 02-18-2010 |
