【 摘 要 】

Weather conditions cause changes in the environment around the arc and wires of transmission lines, which affects the accuracy of transmission line parameters. In order to accurately calculate the line parameters under different meteorological conditions, the influence of temperature, ice cover and wind speed on the arc of transmission lines and the influence of space dielectric constants on temperature, air humidity, ice cover and fog are studied. The analysis and calculation method of the resistance, reactance and capacitance parameters after the change of wire and ground arc vertical position and space dielectric constant are studied.
