High voltage winding lead and terminal structure

Abstract

High voltage winding lead and terminal structures are disclosed. In the winding of slot wound transformers by means of a plurality of coils of fine wire, wherein each coil is of narrow width and large diameter, a severe problem of corona discharge is present in trying to make a connection to the inner end of each of the winding coils. To solve this problem, relatively wide members are provided on the coil form to form the winding slots. Grooves are provided in these members with a conductor of large cross section being placed in the groove to make an electrical connection with the inner end of each of the winding coils. Preferably, the large conductor is mounted tangent to the inner turn of the coil and the fine wire of the coil is pulled in contact with the conductor of large cross section by automatic winding machinery.
