Abstract
A voltage transformer for an insulated high-voltage switching apparatus of the type including a metallic outer tubular casing in which an electrical conductor is disposed, and a tubular sleeve disposed about the conductor within the casing. The sleeve forms both a surface type electrode and in conjunction with the electrical conductor of the apparatus, a high potential capacitor. The improvement of the invention comprises a coupling arrangement, fabricated of electrical insulation material, which is fastened at one end of the tubular sleeve and is coupled to the casing of the apparatus. A support arrangement, also fabricated of electrical insulation material, is fastened at the other end of the tubular sleeve and disposed in engagement with the inner surface of the apparatus casing. The coupling and support arrangements function in conjunction with each other to support the tubular sleeve in the apparatus casing about the electrical conductor.
