Abstract
A slip ring has a rotating portion configured to take in signals from rotating electric transmission elements, and communicate those signals into a static portion. The rotating portion has a plurality of resistors which rotate. The resistors have an outer peripheral surface, and a containment ring surrounding the outer peripheral surface of the plurality of resistors. A method of testing a rotating component is also disclosed.
Claims16
A system comprising:
- a slip ring having a rotating portion configured to take in signals from rotating electric transmission elements, and communicate those signals into a static portion;
- the rotating portion having a plurality of resistors which rotate, said resistors having an outer peripheral surface, and a containment ring surrounding said outer peripheral surface of said plurality of resistors;
- and
- gauges are mounted on a component which is rotating, and said gauges being said rotating electric transmission elements, and said resistors connected to wires that each extend from one of said resistors to one of a plurality of turrets, or one of a plurality of strain gauges such that said turrets communicate electrical signals through brushes to a control, and said containment ring containing said resistors during rotation of said rotating portions.

A method of testing a rotating component comprising the steps of:
- (a) rotating a component and including gauges on the rotating component, and transmitting signals from said gauges through a slip ring and to a controller to analyze those signals;
- (b) the slip ring including a plurality of resistors which are rotated, and said resistors having an outer peripheral surface, and a containment ring surrounding said outer peripheral surface of said plurality of resistors, and said resistors connected to wires that each extend from one of said resistors to one of a plurality of turrets, or one of a plurality of strain gauges such that said turrets communicate electrical signals through brushes to a control, and said containment ring containing said resistors during rotation of said rotating portions;
- and
- (c) said component is a turbine.
