20080314873 | SWITCHING CHAMBER FOR A HIGH-VOLTAGE SWITCH HAVING A HEATING VOLUME FOR HOLDING QUENCHING GAS PRODUCED BY SWITCHING ARCS - A switching chamber is intended for a gas-insulated high-voltage switch and contains a contact arrangement with two arcing contacts, which move relative to one another along an axis, with an insulating nozzle, an insulating auxiliary nozzle, a heating volume and a heating channel. The heating channel is routed partially axially between the insulating nozzle and the insulating auxiliary nozzle and connects an arcing zone to the heating volume. A section of the heating channel which opens into the heating volume is inclined inward with respect to the axis. Hot gas which is formed when a short-circuit current is disconnected in the arcing zone therefore flows with a velocity component directed inward into the heating volume, and can penetrate deeply into the heating volume in areas close to the axis. The quality of a quenching gas which is formed in the heating volume from the hot gas and cold gas which is already present, with this quenching gas being used to blow a switching arc which has been struck in the arcing zone during disconnection, can thus be improved. | 12-25-2008 |
20090078680 | ARC CHAMBER OF A HIGH-VOLTAGE SWITCH WITH A HEATING VOLUME OF VARIABLE SIZE - An arc chamber is disclosed for a gas-insulated high-voltage switch. It contains a heating volume for accommodating compressed quenching gas from an arc zone. A part of the wall of the heating volume is formed by a piston which is displaceable against a restoring force. The piston is arranged as differential piston and has on its side facing away from the heating volume a piston step which forms a first working surface (A | 03-26-2009 |

20100219161 | GAS-INSULATED HIGH-VOLTAGE CIRCUIT BREAKER WITH A RELIEF DUCT WHICH IS CONTROLLED BY AN OVERFLOW VALVE - A high-voltage circuit breaker includes two arcing contacts, which are capable of moving relative to one another along an axis, an insulating nozzle, a heating volume for accommodating quenching gas, a heating channel, and an overpressure valve. The pressure of the quenching gas is based on the energy of a switching arc, which is formed when the breaker opens and generates arcing gas, and the heating channel opens out, with axial alignment, into the heating volume. The heating channel connects an arc zone, and the overpressure valve limits the pressure of the quenching gas by opening a relief duct, which opens out into an expansion space. In high-current switching, the pressure of the arcing gases in the arc zone is limited, and the quality of the quenching gas stored in the heating volume is improved, due to the relief duct having an outflow section extending in the radial direction. | 09-02-2010 |

20120037599 | CIRCUIT BREAKER - An exemplary high voltage circuit breaker includes an interruption chamber that is filled with an extinguishing agent. The interruption chamber having at least two separable arcing contact pieces that are coaxially arranged and an arcing zone in which an electric arc is producible during an interruption process. The interruption chamber includes at least two inlets and at least one outlet located in between the two inlets. The inlets and the at least one outlet are connected with the arcing zone such that the electric arc is extinguishable in at least three arc interruption zones by means of extinguishing flows streaming out of the at least two inlets into the arcing zone upon pressurization and introduction of a portion of the extinguishing agent in the arcing zone, and leading an amount of the extinguishing flows through the outlet out of the arcing zone. | 02-16-2012 |
20130021709 | CONDUCTOR ARRANGEMENT FOR REDUCING IMPACT OF VERY FAST TRANSIENTS - A conductor arrangement is provided for reducing very fast transients in high voltage applications. The conductor arrangement includes a conductor element having a main conducting orientation, and a conductive annular shell element coaxial to the conductor element, thus forming an annular cavity around the conductor element. The annular shell element in the main conducting orientation includes a first end portion and a second end portion. The first end portion is conductively connected to the conductor element. The second end portion includes an annular collar which is substantially coaxial to the conductor element, thus together with the conductor element forming a coaxial capacitor which has a solid material filling. The capacitor includes a surge arrester which may serve as an energy conversion portion. | 01-24-2013 |
20150021297 | Circuit Breaker - A circuit breaker including two contacts, a pressurization chamber, a nozzle arrangement designed to blow an arc in a quenching region, with a narrowest passage of a pressurization chamber outflow channel to be passed by outflowing quenching gas defining a pressurization chamber outflow limiting area, a narrowest passage of a nozzle channel to be passed by outflowing quenching gas defining a nozzle outflow limiting area, the smaller area of which defining an absolute outflow limiting area, with quenching gas having a global warming potential lower than the one of SF | 01-22-2015 |

20100136709 | RECEPTACLE AND METHOD FOR THE DETECTION OF FLUORESCENCE - The invention relates to a liquid receptacle comprising a bottom and sidewalls for holding a liquid. The bottom encompasses a flat sensor surface that is in contact with the liquid when the receptacle is filled, a light-incident area that is located below the sensor surface and is suitable for focusing light onto the sensor surface, a light emergence area, and a cover area that is suitable for reflecting light from the sensor surface such that the light can emerge through the light emergence area. The invention further relates to a method for qualitatively or quantitatively determining an analyte in such a liquid receptacle. In said method, excitation light is focused onto the sensor surface via the light-incident area such that a luminescent marker which characterizes the analyte is excited, and the generated luminescence is then reflected onto the cover surface and is detected after emerging through the light emergence area. The invention also relates to an analysis device comprising a holder for a liquid receptacle, a light source that is disposed such that the light thereof can be focused onto the sensor surface of the liquid receptacle via the light-incident area, and a detector which is arranged in such a way as to be able to detect the light emerging from the light emergence area of the liquid receptacle. | 06-03-2010 |
