Intelligent lightning arrester

The invention relates to the field of lightning arresters, in particular to an intelligent lightning arrester. An intelligent lightning arrester comprises an upper conductor used for connecting a circuit to be protected; the lower conductor is grounded; the insulating cylinder is used for connecting the upper conductor and the lower conductor and forming an accommodating space; the piezoresistor is positioned in the accommodating space and is connected in series with the upper conductor and the lower conductor; the monitoring assembly is used for continuously monitoring the current passing through the intelligent lightning arrester and responding when the current is continuously greater than a threshold value; the shunt release is connected in series with the upper conductor, the lower conductor and the piezoresistor and is short-circuited when the monitoring assembly responds; and the lithium battery is used for supplying power to the monitoring assembly and the shunt release. Detection is continuously carri
