| 20110304342 | DEVICE FOR A SYSTEM COMPONENTS OF A HIGH-VOLTAGE IMPULSE TEST SYSTEM - The present invention relates to a device for system components of a high-voltage impulse test system, preferably for quality assurance of power transformers. According to the invention, a common base frame having only one main electrode common to the system components is proposed for the spatial collection of the system components. | 12-15-2011 |
| 20110220829 | PRESSURE RELIEF VALVE - A pressure-relief valve has a housing having an annular flange defining a pressure-vent hole centered on an axis and having an axially directed end face and a radially outwardly directed outer surface. A cap can fit axially over the flange in a closed position and has a skirt radially juxtaposed with the outer surface in the closed position. A spring braced axially between the cap and the housing urges the cap into the closed position. A first annularly continuous seal secured to the end face axially bears on and hermetically engages the cap in the closed position. A second annular seal secured to the outer surface has an outer edge elastically engaging the skirt in the closed position and formed with a notch through which fluid trapped between the first and second seals in the closed position can drain. | 09-15-2011 |
| 20090288934 | Energy Store - The invention relates to an energy store for a load tap changer with a longitudinally movable lifting carriage and an also longitudinally movable snap-action carriage which follows the movement of the lifting carriage after being triggered and whose longitudinal movement is converted into a rotary movement of an output shaft that actuates the load tap changer. In order to do so, two rolls which are guided in an especially geometrically designed guide rail are disposed on the snap-action carriage. Only one of the two rolls is positively guided in the guide rail during the first part of each movement of the snap-action carriage while the other roll can be moved freely. The second roll that could previously be moved freely is then positively guided during the second part of the movement while the roll which was previously guided can be moved freely. The roll which was initially guided is positively guided once again during the third part of the movement. | 11-26-2009 |
| 20090140705 | Device for Regulating Electrical Voltage - The invention relates to a device for regulating the electrical voltage in power mains, comprising a regulating transformer. Optionally interconnecting only three winding taps and a separate reactor winding with a total of four switching elements, enables five different voltage levels to be set. | 06-04-2009 |
