Abstract

Development of the three phases in one tank type SF6 gas-insulated 110 kV voltage transformer is introduced. The single-phase double-column overlap core was designed

and its 7-step trapezoid section made the utilization factor close to 1. The high-voltage winding adopted the tower structure with a two-layer mode in order to fully utilize interlayer isolation. The three-dimensional electric field distribution was calculated by finite element method for the design of main insulation structure. After optimum design

reasonable selection of materials and fine fabrication

this type of transformers passed all tests and met the relational standard.
