  • High voltage isolation transformer
    Patent number: 4510476
    Abstract: A high voltage isolation transformer (10) is provided with primary (30) and secondary (32) coils separated by discrete electrostatic shields from the surfaces of insulating spools (12,14) on which the coils are wound. The electrostatic shields are formed by coatings (49,59,50,60) of a compound having a low electrical conductivity which completely encase the coils and adhere to the surfaces of the insulating spools (12,14) adjacent to the coils. Coatings (47,48) of the compound also line axial bores of the spools, thereby forming electrostatic shields separating the spools from legs (18,20) of a ferromagnetic core (16) extending through the bores. The transformer is able to isolate a high constant potential applied to one of its coils, without the occurrence of sparking or corona, by coupling the coatings lining the axial bores to the ferromagnetic core and by coupling one terminal of each coil to the respective coating encasing the coil.
