Abstract
For the correct evaluation of the safety of the transmission line, taking the transmission line elements (conductor&earth wire, insulator and hardware) as the analysis objects, the reliability analysis model was established, by analyzing the affecting factors of load effect of transmission line elements such as the calculation formula and distribution curve of permanent load and wind load, the statistical parameters of load effect were obtained;Considered the uncertainty of material properties, geometry and computational model, the resistance statistical parameters were obtained. Using a second-order moment method, calculated the reliability index of the transmission line element in maximum wind condition .Results show that the reliability level of the transmission line elements designed by current speciifcation of safety factor was high. The calculation results can provide reference for the establishment of probability limit state design methods of the transmission line.关键词
