GIS opening and closing state current detection method and device based on CNN network

The invention discloses a CNN network-based GIS opening and closing state current detection method and device. The method comprises the steps of collecting opening and closing states of a disconnecting link and a grounding knife in each state of GIS equipment and a corresponding coupling capacitance current data set; preprocessing the collected current data, and constructing a training set of the network; constructing a CNN network; optimizing the CNN network parameters by using a particle swarm optimization algorithm to obtain optimal CNN network parameters; acquiring disconnecting link and grounding switch fault current data of the GIS equipment in real time, preprocessing the data, inputting the data into the optimal CNN network, and outputting a GIS opening and closing state judgment result by using the optimal CNN network; the method has the advantages that the execution speed is high, the real-time performance is high, after the model is trained, the output result is accurate, and the reliability is hig
