Title: Defects Analysis of 550kV OIP Transformer Bushing
Abstract:The defect of a 550kV transformer OIP bushing was investigated. Finite element model of the bushing is established and the electric field is obtained, the insulation design of bushing is investigated,...The defect of a 550kV transformer OIP bushing was investigated. Finite element model of the bushing is established and the electric field is obtained, the insulation design of bushing is investigated, and the design margin of various key points of bushing is analyzed. The detailed modelling and simulation of wrinkles on foils is carried out. The influence of wrinkle size and position on the local electric field is analyzed. According to the disassembly and simulation results, suggestions for the design and manufacturing technique of bushing are given.Read More
