The invention discloses a line arrester action reliability evaluation method based on fusion of multiple parameters. The method includes the following steps: effective ground lightning at the front and back towers of a target tower at a certain moment, lightning types and lightning current amplitudes are determined by calculating thunder correlation degrees according to data of a lightning monitoring system and a transmission line distributed fault diagnosis system; counterstrikes and lightning shielding failure shunting coefficients are calculated by using parameters of the tower and earth wires to further determine a current passing through an arrester during each lightning, and the current is compared with an action threshold of a counter of the arrester to determine the number of required action times of the arrester of the tower within the time period, the number of the required action times is compared with an action number of the counter of the arrester within the time period toprovide a reliable reference for the action number of the counter of the arrester, so as to accurately evaluate an operation state and action reliability of the arrester.
