| 20090008367 | SWITCHING CHAMBER FOR A GAS-INSULATED HIGH-VOLTAGE SWITCH - The switching chamber is intended for a gas-insulated high-voltage switch. It contains a housing filled with insulating gas and a contact arrangement held in the housing. The contact arrangement has, in a coaxial arrangement, the following components: two switching pieces, which are capable of being moved relative to one another along an axis, with in each case one arcing contact and in each case one tubular conductor containing a rated current contact, an insulating nozzle, and a compression apparatus with a fixed piston and a cylinder. A moveable tubular conductor of the two tubular conductors forms the wall of the cylinder, is electrically conductively and rigidly connected to one of the two arcing contacts via a base of the cylinder and bears the insulating nozzle. | 01-08-2009 |
| 20090261071 | GAS-BLAST CIRCUIT BREAKER WITH A RADIAL FLOW OPENING - A gas-blast circuit breaker is disclosed which includes a first contact and a second contact which can move relative to one another along a longitudinal axis. A blowout volume is arranged around the first contact. The blowout volume can be connected via a gas channel to an arc zone, in order to blow out an arc which is struck when the first contact is disconnected from the second contact. The blowout volume can be bounded radially on an outside by a separating element which separates the blowout volume from a low-pressure area. A flow opening, which allows a gas exchange, can lead in a radial direction from the low-pressure area into the blowout volume. | 10-22-2009 |
| 20090266795 | TRANSMISSION FOR AN ELECTRICAL CIRCUIT BREAKER - An electrical circuit breaker includes a first contact piece with a first consumable contact; a second contact piece with a second consumable contact; a drive for moving the first contact piece along a switching movement axis; and a transmission for transmitting the movement of the first contact piece to a movement of the second contact piece. The transmission has a first lever, a pivoting element which can pivot about a pivoting shaft, and a transmission mechanism for transmitting a pivoting movement of the pivoting element to a movement of the second contact piece. | 10-29-2009 |

| 20110062116 | SELF-BLOWOUT CIRCUIT BREAKER HAVING A FILLING AND OVERPRESSURE VALVE - A self-blowout circuit breaker is disclosed which includes contacts for connecting or disconnecting a circuit, a heating volume, a compression volume and an exhaust volume. The compression volume can be connected to the heating volume by at least one first valve, which heating volume is in turn connected to an arc zone. Upon the disconnection of the circuit, while a first arcing contact is being disconnected from an associated second arcing contact, an arc is produced between the two arcing contacts in the arc zone. The compression volume is separated from the exhaust volume by a combined filling and overpressure valve which is formed as at least one plate, and has at least one tab which is formed in the plate. | 03-17-2011 |
| 20110120975 | GAS-INSULATED HIGH-VOLTAGE SWITCH - A high-voltage switch contains two contact members, which can be moved relative to one another along an axis, a nozzle for blowing out a switching arc with quenching gas, and a stationary direction-changing transmission, which is connected to the nozzle and to the second contact member. The nozzle has a hollow insulating body, and a metallic annular body which is arranged at a blowing-out end of the nozzle, is connected in a formfitting manner to the insulating body, and supports an input or output drive element of the direction-changing transmission. This switch can be manufactured easily and at low cost, and provides good mechanical and electrical characteristics. The annular body has a concentrically arranged intermediate ring, which causes the form fit with the insulating body, and a ring, which is pushed onto the intermediate ring and is attached to the intermediate ring, for supporting the input-drive or output-drive element. | 05-26-2011 |
| 20110163069 | GAS-INSULATED HIGH-VOLTAGE SWITCH - The high-voltage switch exhibits a compression space of small dimensions, in which, on interruption of a current, insulating gas exhibiting quenching characteristics is compressed mechanically to form quenching gas with the aid of an operating mechanism of the switch. When a small current is interrupted, a sufficient quantity of quenching gas can thus be provided with little mechanical operating force. When a large current is interrupted, quenching gas communicates from the compression space into an expansion volume above a response pressure, keeping the operating force low, of a pressure relief valve. A large quantity of quenching gas is then available for successfully interrupting a large current whilst the operating force is kept low. | 07-07-2011 |
