Abstract
A separator is disclosed which provides an electrically insulating layer between groups of windings in an electrical apparatus, such as a rotating electrical machine. The separator comprises a matrix of interconnected rods. This can allow air gaps to be present between groups of windings, which may improve the cooling efficiency of the apparatus.
Claims29
An electrical apparatus, including a plurality of groups of windings at different electrical potentials, the electrical apparatus comprising a separator which provides an electrically insulating layer between groups of windings at different electrical potentials, the separator comprising a matrix of interconnected rods which defines a plurality of cells in two directions.
A separator which provides and electrically insulating layer between groups of windings in an electrical apparatus, the separator comprising a matrix of interconnected rods, the separator further comprising a tag which holds the separator in position while a group of windings is being formed on the separator.
A method of winding an electrical apparatus, the electrical apparatus including a plurality of groups of windings at different electrical potentials, the method comprising inserting a separator between groups of windings so as to provide an electrically insulating layer between groups of windings at different electrical potentials, the separator comprising a matrix of interconnected rods which defines a plurality of cells in two directions.
