Abstract
A design method of aeroelastic model wind tunnel for substation frame lightning rod structure was presented in this paper in order to improve the effectiveness of wind tunnel design of aeroelastic model. The wind-induced vibration of frame lightning rod was studied aiming at the breakage of lightning rod of 220 kV side frame in a 500 kV substation, and the wind tunnel test of three air-elastic models of lightning rod was conducted. The dynamic strain at the bottom of the lightning rod is obtained by the fiber grating strain measurement technique. The wind-induced dynamic response of the structure is studied, the dynamic effect of wind on the structure is analyzed, and the reference is provided for further study on fracture.
