    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.

    摘要: A resonator ring for a combustor basket, in particular for a gas turbine power plant, which has at least one ring, wherein the ring or the rings has or have apertures, wherein insert plates are connected to the ring or the rings within the aperture. A method for producing a resonator ring, in which a ring or rings is or are produced from a first metal, then insert plates made of a, preferably cast, second material are connected to the ring or the rings, and individual resonator boxes are produced.
