Calculation and Analysis on Surface Electric Field Intensity of Bundled Conductors for UHVAC Transmission Lines
摘要
Abstract
According to the actual situation of the UHVAC transmission lines, the surface electric field intensity on the bundled conductors is calculated based on the dipole method. Then, the effects of the factors, such as the average height of lines to ground, layout, bundled distance, distance among phases, number of bundles, cross-section area of a conductor, phase sequence, and shielding lines, on the surface electric field intensity of bundled conductors are analyzed and discussed. The results show that: 1 The surface electric field intensity of the bundled conductors is different; 2 The number of bundles and cross-section area of a conductor impose significant effects on the surface electric field intensity, while other factors, such as the average height of lines to ground, layout, bundled distance, and distance among phases, impose relatively smaller effects on the surface electric field intensity; 3 The phase sequence has significant effect on the surface electric field intensity of the top and bottom phases of transmission lines, and has smaller effect on the middle phase; and 4 The shielding lines can enhance the surface electric field intensity of bundled conductors.关键词
