20080217152 | HIGH-VOLTAGE CIRCUIT BREAKER AND SWITCH ARRANGEMENT - The disclosure relates to an electrical switching device, e.g., a high-voltage switch, with a mantle-side electrical connection. According to the disclosure, an encapsulated angle disconnector is fitted between the mantle-side electrical connection and the outdoor bushing or an outgoing cable, by means of which angle disconnector the electrical connection is deflected in the disconnector plane, e.g., toward the vertical in the operating position of the switching device. Exemplary embodiments relate, inter alia, to: a horizontal electrical connection and a, 90° disconnector; an additional tilting angle (β) of the angle disconnector about the disconnector input axis; a plurality of mantle-side horizontal electrical connections with associated angle disconnectors, which are tilted away from one another. | 09-11-2008 |
20120153976 | DEVICE WITH OVERVOLTAGE PROTECTION AND METHOD FOR ITS TESTING - Exemplary embodiments are directed to a device with overvoltage protection that includes a varistor which can be connected by a first connection via a first line to high-voltage potential in a circuit arrangement, while a second connection is connected to ground via a second line. Furthermore, an additional impedance is provided, which can be connected between the second connection and ground or the first connection and the high voltage, or is mounted fixed in this position. The corresponding line can be interrupted by a switching arrangement. In order to test the withstand voltage of the circuit arrangement, at least one of the first and second line is interrupted and an additional impedance is inserted. A test voltage is applied to the circuit arrangement. After the overvoltage test, the interruption in at least one of the first and second lines is removed again. | 06-21-2012 |
20130250487 | SWITCH BAY FOR HIGH-VOLTAGE SWITCHGEAR ASSEMBLY, AND METHOD FOR INSTALLATION THEREOF - A switch bay for a high-voltage switchgear assembly includes three gas-insulated circuit breakers each for corresponding one of first, second and third current phases. The circuit breakers are arranged parallel to one another along an x direction. Three switch disconnectors are provided for a corresponding one of the first, second and third current phases. The switch disconnectors each have a corresponding isolating gap. The isolating gaps are arranged parallel to one another. A first busbar phase conductor section of the first current phase and a second busbar phase conductor section of the second current phase extend parallel to one another along a y direction, which runs transversely with respect to the x direction. A busbar connection is provided for connection of a third busbar phase conductor section of the third current phase. | 09-26-2013 |
