Simulation Analysis of Power Frequency Electric Field Around T Connection Tower of Transmission Line

论文摘要

As a new type of line connection,T connection tower has been applied in engineering,but it makes the distribution of electric field around the tower more complicated.In order to determine the electric field distribution around the T-tower and the typical working position of the tower.A 110 kV double-circuit AC T-connected tower is taken as the research object.The three-dimensional finite element software COMSOL is used to model the tower,wire and other components.The influence of the arrangement of the wire phase sequence on the electric field distribution is analyzed.The surrounding electric field distribution was simulated.The research results show that the field intensity around the tower and at the typical operation position of the tower are all within the safe range,and the maximum field intensity on the ground is generated on the side of the T-connection line.The calculation results can provide reference for the design of the T-connection scheme of the transmission line.
