Lightning arrester phase angle difference prediction method, device, equipment and storage medium

The invention discloses a lightning arrester phase angle difference prediction method and device, equipment and a storage medium. The method comprises the following steps: acquiring leakage current of the lightning arrester in different time periods and at least two kinds of environmental data influencing the leakage current; processing the leakage current to obtain phase angle difference data; training a BP neural network model based on the phase angle difference data and the environment data; and inputting environment data needing to be predicted into the trained BP neural network model to obtain target phase angle difference data. According to the method, a BP neural network model is trained according to phase angle difference data of leakage current and at least two kinds of environmental data, and the phase angle difference data of the lightning arrester in the actual situation is predicted according to the trained BP neural network model, so that the resistive current of the lightning arrester can be de
