Abstract
A high voltage bushing comprising an insulator enclosing a conductor and a mounting flange slid over the insulator. The outer surface of the insulator defines a flange seat for contacting one end of the mounting flange. A gasket may be positioned on the flange seat between the insulator and mounting flange to form a gas tight seal to prevent the escape of hydrogen. A layer of epoxy attaches the remaining portion of the mounting flange to the insulator. The insulator of the high voltage bushing is made from a composite material rather than porcelain as is traditionally used, while a high temperature asphalt material is also used.
Claims16
A high voltage bushing, said bushing comprising:
- an insulator adapted to fit over a conductor, said insulator including an outer surface defining a flange seat;
- a mounting flange mounted over the insulator, said mounting flange including an axial portion and a radial portion located at one end of the axial portion, the axial portion positioned on the flange seat of said insulator at an end opposite of the radial portion, the remaining portion of the axial portion joining said insulator by an adhesive layer.
A high voltage bushing, said bushing comprising:
- an insulator adapted to fit over a conductor;
- a mounting flange mounted over the insulator, said mounting flange including an axial portion and a radial portion located at one end of the axial portion;
- a gasket positioned between the insulator and the axial portion of the mounting flange at an end opposite the radial portion;
- and
- an adhesive layer between the insulator and the axial portion of the mounting flange and extending from the gasket to at least the end at which the radial portion is located.
A high voltage bushing, said bushing comprising:
- an insulator adapted to fit over a conductor, said insulator including an outer surface;
- a mounting flange mounted over the insulator, said mounting flange including an axial portion facing the outer surface of the insulator and a radial portion located at one end of the axial portion;
- and
- a gasket positioned between the axial portion of said mounting flange and the outer surface of said insulator.
A method of assembling a high voltage bushing, said method comprising:
- providing an insulator, the insulator having an outer surface and defining a flange seat;
- providing a mounting flange, the mounting flange including an axial portion and a radial portion located at one end of the axial portion;
- positioning a gasket on the flange seat of the insulator;
- sliding the mounting flange onto the insulator until an end of the axial portion opposite the radial portion is positioned in the flange seat of the insulator and over the gasket;
- inserting an adhesive between the mounting flange and insulator to connect the mounting flange to the insulator while using the gasket as a dam to prevent leakage of the adhesive.
