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 |
