Method for evaluating running states of lightning arrester, tower and grounding system of power transmission line

The invention discloses a power transmission line lightning arrester, tower and grounding system operation state evaluation method, which comprises the steps of determining corresponding risk thresholds of corresponding target objects of a power transmission line lightning arrester, a tower and a grounding system, obtaining state evaluation characteristic data of the target objects, generating state evaluation characteristic data of the corresponding target objects, and calculating the state evaluation characteristic data of the corresponding target objects. And constructing a running state evaluation model of the corresponding target object, and generating corresponding prediction result information and/or corresponding safety evaluation parameters. According to the method, the state evaluation characteristic data of the corresponding target object is generated by acquiring the corresponding target object data and performing characteristic processing, so that the corresponding operation state evaluation resu
