- Abstract
Non-uniform factor of wind pressure is used to express distribution unevenness of wind pressure acting on the conductor at same time. USA, Japan and Germany etc developed countries have carried out many field measurement about it. Field measurement research in China is less, it is also found during actual operation that many flashover accidents were caused by windage yaw. In order to improve value accuracy of non-uniform factor of wind pressure, this paper formed a set of synchronous observation and measurement system for incline angle of the suspension string and the wind speed corresponding to the incline angle, which was referenced to field measurement method proposed by USA Electrical Science Research Institute. Based on field measured wind speed, the wind load of the whole span of the conductor was calculated. Based on field measured incline angle of suspension string, the wind load acting on the whole span was measured. By comparison of calculated wind load and measured wind load, the non-uniform factor of wind pressure of transmission line corresponding to field environment.
