摘要:
A coil (60). The coil (60) comprises a conductor formed in the shape of winding layers (68). The conductor comprises an insulating coating (96) surrounding a conductive core (94). The coil further comprises paper strips (80) disposed proximate one or more of the winding layers (68) to provide strain relief against mechanical forces exerted on the coil (60) and to provide electrical insulation between winding layers (68). In an embodiment where the coil (60) further comprises a core (70) the paper strips (80) are beneficially disposed at corners (70A, 70B, 70C, and 70D) of the core (70) and further between winding layers (68) at the corners (70A, 70B, 70C, 70D).

摘要:
In a telemetry system (100) in a high-temperature environment of a combustion turbine engine (10), a wireless power-receiving coil assembly (116) may be affixed to a movable component (104) of the turbine engine. Power-receiving coil assembly (116) may include a radio-frequency transparent housing (130) having an opening (132). A lid (134) may be provided to close the opening of the housing. Lid (134) may be positioned to provide support against a surface (120) of the movable component. An induction coil (133) is disposed in the housing distally away from the lid and encased between a first layer (136) and a last layer (140) of a potting adhesive. Lid (134) is arranged to provide vibrational buffering between the surface (120) of the movable component (104) and the layers encasing the induction coil.

摘要:
A gas turbine combustor vibration sensing system includes a non-contact reflective optical vibration sensor adapted for reflecting photons off of a component within the combustor with a photon source and receiving reflected photons with a photon detector. Exemplary combustor internal components include the combustor basket or transition. A vibration analyzer is coupled to the vibration sensor, for correlating photons received by the detector with vibration characteristics of the component. Vibration characteristics in turn can be correlated with combustion characteristics, including by way of example flame front position and flameout conditions. Vibration characteristic information may be used as an operational parameter by a turbine monitoring system to modify operation of a gas turbine.
