Detailed Description

The embodiment of the application provides an equivalent wind speed measuring method and a related device of an overhead transmission line, and solves the technical problem that the current-carrying capacity of the overhead transmission line cannot be accurately calculated due to the fact that the real-time and accurate equivalent wind speed of the overhead transmission line cannot be obtained in the prior art.

In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.
