Abstract
An electrical current collector system includes a rotatable shaft ( ); an electrically conductive slip ring ( ); and a slip ring support assembly ( ). The slip ring support assembly ( ) comprises plural post insulators ( ) spaced radially about the rotatable shaft for attaching the conductive slip ring to the rotatable shaft. The post insulators facilitate adjusting of the position of the slip ring relative to the rotatable shaft, e.g., to provide concentric positioning. The post insulators comprise an attachment/adjustment assembly ( ) for connecting to the slip ring. In one embodiment, the attachment/adjustment assembly comprises a spring plate ( ) which is adjustably biased to provide a preloading displacement that absorbs differential movement due to temperature changes of the slip ring an the rotatable shaft. In one example deployment, the current collector system is provided as part of a rotary transformer system ( ) which, e.g., transfers electrical power between a first electrical system (e.g., first electrical grid) and a second electrical system (e.g., second electrical grid).
