Abstract

The full united frameworks (FUF) of transformer substations belong to wind-sensitive towering structures, and wind load is a decisive control load. Wires, lower leads, and busbars hang on united frameworks. Such suspension component will inevitably affect the wind-induced response characteristics of united frameworks, which must be considered in design. In this study, a 500kV full united substation framework was used as the study object. Six busbars was installed in longitudinal direction on the framework. With the help of finite element analysis software ANSYS, based on random vibration theory, the wind-induced vibration response of the united framework was calculated and analyzed in frequency domain. The wind induced vibration displacement response and the spatial distribution rule of the wind vibration coefficient under the wind load in different wind directions were obtained. The calculation results show that, with the existence of longitudinal busbars, the fluctuation displacement response and the wind vibration coefficient of the transformer framework decreased, which reduced the alternating load of the transformer framework, with the location of the maximum displacement of the fluctuating displacement response transferred to the busbars. The existence of the busbars has little effect on the mean displacement response of the transformer framework, which can be ignored in the design phase of the transformer framework.
