Online monitoring method of lightning arrester

The invention relates to an online monitoring method for a lightning arrester, and the method comprises the following steps: collecting total current signals of the lightning arrester in various working states as sample data, carrying out the preprocessing of the sample data, and dividing the sample data into a training set and a test set; constructing a lightning arrester total current analysis model, inputting the training set into the model for training, adjusting each parameter of the model in the training process to obtain the trained lightning arrester total current analysis model, and finally evaluating the recognition rate of the model through the test set; and inputting the lightning arrester total current signal acquired in real time into the trained lightning arrester total current analysis model, and analyzing the working state of the lightning arrester in real time by the model according to the input total current signal. 本发明涉及一种避雷器的在线监测方法，包括以下步骤：采集避雷器各种工作状态下的全电流信号作为样本数据，对样本数据进行预处理后分为训练集以及测试集；构建避
