Abstract

A direct-type lead exit for ultra high voltage (UHV) transformer was designed, and the electric field of the lead exit was calculated and analyzed by using finite element method. Then, its insulation structure was optimized. The stress distribution and displacement of the lead exit under vibration condition were investigated. The reliability of the lead exit was verified by electrical test and vibration test.
