Description
technical field [0001] The invention relates to the technical field of power grids, in particular to a device and method for testing the characteristics of cross-wind noise of transmission line insulators. Transmission line wind noise, especially the characteristics of wind noise generated by insulator strings. Background technique [0002] The audible noise generated by the transmission lines in the power grid system is a common line impact on the environment, and this noise can make people feel restless. The audible noise generated by the transmission line can be roughly divided into two types: one is the corona noise caused by the corona discharge of the wire; the other is caused by the fluid movement of the air, that is, when the wind blows on the wire , insulator strings or wind noise generated when the tower is on. [0003] With the large-scale construction of EHV and UHV transmission lines in my country, the problem of audible noise including wind noise of transmiss...
