摘要： A spark gap assembly includes a sealed chamber, at least two discharge electrodes, and a non-radioactive gas fill within the sealed chamber. The sealed chamber includes first and second end plugs and a vitreous tube having opposite ends, each end being sealed by one of said end plugs. The discharge electrodes extend through the first and second end plugs, respectively, from an exposed portion outside of the sealed chamber to an enclosed portion inside the sealed chamber. The discharge electrodes each have a discharge portion that includes a surface from which electrons of a spark discharge exit or are received, with the discharge surfaces of the discharge portions facing each other to thereby define a spark discharge gap between the discharge surfaces of the two discharge electrodes. The gas fill within the sealed chamber includes one or more non-radioactive isotopes of one or more noble gases.

摘要： Variable rate ignition method and system that take advantage of knowledge and analysis of environmental conditions and/or operational conditions. A variable ignition rate for igniting the engine permits an optimal use of the igniters and thereby prolongs their life as well as its associated maintenance schedule. Operating costs and durability are also enhanced. Furthermore, flexibility is enhanced since any changes to the method of determining the best spark rate can be made through update in the software of the engine controller instead of change in the hardware (e.g., the exciter).

摘要： An igniter that uses the change or fluctuation pressure in a system or process to generate electrical energy by means of a piezoelectric element. This electrical energy is then relayed to an ignition device or devices that ignites combustible liquid or mixture of liquids and gasses or mixtures of gasses. The ignition can take place either in the systems combustion chamber, or, in the case of burn off of excess gasses/fluids, at the systems vent.

摘要： A monitoring arrangement for a gas turbine spark ignition system in which the spark discharge current oscillates at a known frequency includes a sonic sensor accoustically coupled to the spark igniter, a filter for passing only those signals from this sensor which have a frequency corresponding to that of the discharge current and indicating means responsive to the filter output for indicating that the spark igniter is operating. An additional optical sensor may provide a signal response to a spark gap in the ignition system, signals from both sensors being required to energize the indicating means.

摘要： An igniter test unit produces a square wave voltage that is applied across a parallel circuit comprising a first capacitor and a series arrangement of a second capacitor and diodes. An inductance and a thyristor are connected across the first capacitor, in series. When the thyristor is rendered conductive the voltage across the diodes becomes the sum of the voltages across the capacitors, this voltage being applied across the igniter. Switching of the thyristor is controlled such that the voltage is applied to the igniter in increasing steps of 25 volts until the breakdown occurs at the same voltage five times in succession. The voltage across the igniter is determined by applying it across a capacitive divider, one capacitor being discharged in steps, and the number of steps required to reduce the voltage to a reference value is counted.
