Abstract:
1. A maintenance-free electrical bus assembly comprising: a plurality of electrical bus members; at least one bus joint, each of said at least one bus joint comprising an electrical connection of two or more of said electrical bus members; a fastener assembly fastening said at least one bus joint and maintaining the electrical connection between said electrical bus members of said at least one bus joint, said fastener assembly comprising: at least one first fastening element including a plurality of first threads, at least one second fastening element including a plurality of second threads, said second threads of said at least one second fastening element being structured to threadably engage said first threads of a corresponding one of said at least one first fastening element, wherein said second threads of said at least one second fastening element are farther structured to perpetually secure said first threads and said corresponding one of said at least one first fastening element, in order to resist undesirable loosening of said at least one bus joint once said fastener assembly bas been fastened; wherein said electrical bus members comprise at least one first electrical bus member and at least one second electrical bus member; wherein said at least one first fastening element of said fastener assembly comprises at least one threaded fastener having a plurality of first threads; wherein said at least one second fastening element of said fastener assembly comprises at least one threaded portion of said at least one first electrical bus member; wherein said at least one threaded portion includes a plurality of second threads; wherein said second threads of said at least one threaded portion of said at least one first electrical bus member engage said first threads of a corresponding one of said at least one threaded fastener; and wherein said at least one first electrical bus member is perpetually electrically connected to said at least one second electrical bus member when said corresponding one of said at least one threaded fastener is tightened; wherein said at least one threaded fastener comprises at least one bolt; wherein said at least one second electrical bus member includes at least one aperture; and wherein a corresponding one of said at least one bolt is inserted through said at least one aperture of said at least one second electrical bus member; and wherein said at least one second electrical bus member comprises a single power bus bar; wherein said at least one first electrical bus member comprises a current transformer bushing having an end; wherein said at least one threaded portion comprises a threaded bore in the end of said current transformer bushing; wherein said at least one aperture comprises a single aperture of said single power bus bar; and wherein said at least one bolt comprises a single bolt inserted through said single aperture of said single power bus bar, said single bolt being perpetually secured within said threaded bore of said current transformer bushing when said single bolt is tightened, thereby resisting said current transformer bushing from loosening with respect to said single power bus bar.
