摘要： A mid-frame section of a gas turbine engine having a radial clearance adjustability and a method for adjusting a radial clearance to a rotor in a mid-frame section of a gas turbine engine are presented. The mid-frame section includes a radial clearance adjusting assembly arranged at a compressor exit diffusor. The radial clearance adjusting assembly is configured to adjust the radial clearance to the rotor such that the rotor is concentric with respect to components of the mid-frame section, such as the compressor exit diffusor and shaft cover. The radial clearance adjusting assembly provides radial clearance adjustability in the mid-frame section at multiple locations, such as at forward end and aft end of the compressor exit diffusor. The radial clearance adjusting assembly improves efficiency of the gas turbine and reduces service and operating cost of the gas turbine engine.

摘要： A vacuum interrupter for switching voltages, in particular high voltages, includes at least one envelope, at least one fixed contact, at least one movable contact, and control elements in particular having different lengths and/or widths disposed on the at least one vacuum interrupter. An assembly includes the vacuum interrupters electrically connected in series, in particular by control elements disposed on the at least two vacuum interrupters, and/or by control elements of one vacuum interrupter connected in series to control elements of another vacuum interrupter, in particular of all vacuum interrupters. A method for grading or controlling voltage distribution among vacuum interrupters uses control elements, in particular capacitors and/or resistors, disposed on the vacuum interrupters, in particular in a housing along with the vacuum interrupters and/or along with control elements of different vacuum interrupters that are connected in series.

摘要： The invention relates to a method for operating an electrolysis plant for producing hydrogen and oxygen as product gases, wherein the hydrogen product gas, which additionally contains oxygen as a foreign gas, is fed from an electrolyser to a downstream gas separator, wherein when a predefined limit value for the oxygen concentration in the hydrogen product gas is exceeded, hydrogen having a low oxygen concentration is fed to the gas separator such that the oxygen concentration in the hydrogen product gas is lowered. The invention further relates to a corresponding electrolysis plant.

摘要： A method reconfigures an IoT device which is connectable to a cloud backend. The method includes: storing an access code that is input locally in the cloud backend and storing the access code or check information formed on the basis thereof on the IoT device. The method further includes reconfiguring the IoT device, requesting the access code from the cloud backend, inputting the requested access code on a local configuration interface of the IoT device or on an input device connected to the local configuration interface of the IoT device, and comparing the input access code against the access code stored on the IoT device, or the check information formed on the basis thereof. The IoT device is enabled for reconfiguration upon a positive comparison of the input access code against the access code stored, or the check information formed on the basis thereof.

摘要： An ignition apparatus for a spark gap arrangement containing at least a first and a second ignition capacitor for voltage division of a voltage between a first and a second electrode of the spark gap arrangement. A first trigger spark gap is arranged in a first parallel branch with respect to the first ignition capacitor, and a second trigger spark gap is arranged in a second parallel branch with respect to the second ignition capacitor. A first ignition resistor is disposed in the first parallel branch, wherein a first potential point between the first ignition resistor and the first trigger spark gap is connected to an ignition electrode of the second trigger spark gap. Furthermore, a spark gap arrangement containing the ignition apparatus, an arrangement containing a high-voltage device and the spark gap arrangement for protecting the high-voltage device, and a method for igniting the spark gap arrangement are disclosed.

摘要： A method of controlling a combustor of a gas turbine engine, the method comprising the steps
supplying a total fuel quantity to the combustor dependent on a load of the gas turbine engine, the total fuel quantity is split into a pilot fuel quantity and a main fuel quantity via a scheduled pilot fuel split, the pilot fuel split is the percentage of the pilot fuel quantity of the total fuel quantity,
monitoring combustion instability,
applying a steady state active pilot split offset to the scheduled pilot fuel split when a predetermined temperature of the combustor is exceeded and/or a predetermined value of combustion instability is exceeded to create a steady state pilot fuel split,
monitoring a condition of the gas turbine engine that influences an air/fuel ratio in the combustor,
disabling the steady state active pilot split offset when the condition of the gas turbine engine is indicative of a transient condition and when a threshold value of combustion instability is exceeded, and
applying a transient active pilot split offset to the steady state pilot fuel split while maintaining the total fuel quantity being supplied at any point in time, the transient active pilot split offset and the steady state active pilot split offset result in a total split offset,
the total split offset being greater than the steady state active pilot split offset and the rate of change of the transient active pilot split offset is faster than the rate of change of the steady state active pilot split offset.-
