Condenser-type electrical bushing with central electrode aligning wedging blocks

A condenser bushing for electrical apparatus, comprising:

• a cylindrical mounting flange having a predetermined inside diameter;
• an upper casing connected to the mounting flange;
• a lower casing coaxially positioned with said upper casing;
• a central electrode positioned within said upper and said lower casings, said electrode being supported by said upper casing, said electrode supporting said lower casing;
• a condenser section wound about said central electrode, said condenser section having an outside diameter that is smaller than the inside diameter of said mounting flange;
• and
• means for centering said condenser section within said mounting flange, said means including a plurality of triangular wedging blocks, said means being rigidly attached to said condenser section such that the combination of said outside diameter of said condenser section and said means for centering is larger than said inside diameter of said mounting flange thus preventing said condenser section and said central electrode from falling into the electrical apparatus upon mechanical failure of said said upper casing.
