Definitions

  • the invention relates to an electronic security system to avoid an overspeed condition in the event of a shaft break by detection of the breaking of the wave and subsequent Interrupting further energy supply, in particular in a gas turbine engine.
  • the invention has for its object a security system to detect a wave break and to interrupt the further supply of energy to the drive side End of the shaft to be specified, which with little assembly, construction and space requirements reliably and with little wear works and ensures short switch-off times.
  • the essence of the invention consists in the fixed assignment of a Fiber to the scope of the wave to be monitored, and indeed in their longitudinal direction and rotating with it, as well the severing of the wave break Optical fiber and the corresponding interruption of the forwarding the one serving as a measuring element in this way Light guide on the input side of light. This interruption is at the other end of the measuring light guide detected by a sensor and via an evaluation and control electronics as a signal for switching off the Drive energy supply used.
  • the security system designed on this basis is required with the possible external arrangement of the necessary ones optical sensors and light sources no cooling devices. It is only a small number of simple ones Components necessary. The assembly, repair and The maintenance effort is accordingly low. Due to the Speed of light and the associated fast Detection of a wave break can result in short switch-off times for the supply of energy.
  • measuring light guides can be provided, also as a loop for Light entry side can be returned.
  • the light source and the sensors can be the measuring light guide immediately upstream or - using additional light guide for feeding and routing of light - be arranged externally.
  • the entry side of the measuring light guide can be axially centric or be offset to the center.
  • the light emission can be done and recorded in the axial or radial direction become.
  • the additional light guide or the light source for feeding of light can be ring-shaped to several measuring light guides arranged in a circular line To supply light from only one light source.
  • the measuring sleeve of an inner tube and an outer tube.
  • the inner tube there are longitudinal grooves for Recording the measuring light guide, so that with one with one Breakage associated breakage of the measuring sleeve also the measuring light guide is cut immediately.
  • the outer tube, the Strength higher than that of the inner tube serves as a support the measuring light guide / s and the inner tube.
  • the measuring sleeve 4 consists of a Inner tube 7 and an outer tube 8, which on both end faces each closed by a base plate 9a, b and 10a, b are.
  • the outer peripheral surface of the inner tube 7 there are two opposite, in the longitudinal direction of the Measuring sleeve 4 holding grooves 11, 12 into which a measuring light guide 13 - flush with the surface of the inner tube 7 finally - is inserted.
  • the outer tube (support tube) 8 supports the measuring light guide 13 against the high centrifugal forces towards the outside and fixes it radially in the holding grooves 11, 12.
  • the measuring light guide 13 is thus in the Circumferential wall of the measuring sleeve 4 embedded.
  • the outer tube 8, that of absorbing the centrifugal forces and centering the Measuring sleeve 4 serves one of the prevailing force effects appropriate strength. That as a break tube acting inner tube 7, however, consists of one less solid, easily breaking material.
  • the measuring light guide 13 runs outgoing from a central inlet bore 14 in the rear Base plate 9a, first between the two rear base plates 9a and 10a, then in the lower holding groove 12, then between the two front base plates 9b and 10b and finally back to the home page in the top Retaining groove 11 to in an exit hole 15 on the outer edge the rear bottom plate 9a to end.
  • the Light source 18 and optical sensor 19 can also be used directly behind the inlet or outlet bore 14, 15 be arranged for the measuring light guide 13, in which If appropriate cooling devices are provided have to.
  • the optical sensor 19 is with evaluation electronics 20 and an electronic control 21 connected, via which is integrated into the fuel supply Fuel shutoff valve 22 based on that of the optical sensor 19 received signals is driven.
  • first additional light guide 16 About the light-emitting end in front of the central arranged input hole 14 lying light supply cable (first additional light guide 16) is constantly light passed through the measuring light guide 13 and due to the rotation the measuring sleeve 4 on the light exit side (exit hole 15) as a constantly repeating light pulse receive. If the low-pressure turbine shaft breaks 1 also breaks the one connected to it at both ends, otherwise arranged with play in the low-pressure turbine shaft 1 Measuring sleeve 4 and preferably their low strength having inner tube 7 (predetermined breaking tube). by virtue of fixing the measuring light guide 13 in the holding groove 11, 12 this is also severed quickly and the light beam interrupted.
  • the registered by the optical sensor 19 Interruption of the light supply serves as a signal for the evaluation electronics 20 and the electronic control 21 to indicate a wave break and to interrupt the Fuel supply to the fuel shutoff valve 22 to the Low-pressure turbine shaft 1 no longer accelerate and the dangerous ones resulting from overspeed Limit or prevent consequences.
