Provided is an intelligent terminal equipment opening-inserting node time-delay test method in an intelligent transformer station, comprising the steps of: analyzing an intelligent transformer station SCD file to obtain an intelligent terminal input virtual terminal list; successively traversing the intelligent terminal input virtual terminal list to obtain the mapping relation between opening-inserting nodes and virtual terminals; selecting intelligent terminal equipment to be detected, connecting the opening-inserting nodes to be tested with test equipment, and setting a test time-delay value; performing time-delay test on the opening-inserting nodes; and displaying the mapping relation between opening-inserting nodes and virtual terminals, and the test result of each virtual terminal associated with the opening-inserting nodes to be tested. The method can obtain the association relation between opening-inserting nodes and virtual terminals according to an Inputs definition, test when the association relation between opening-inserting nodes and virtual terminals is unclear, and verify whether the mapping relation in an intelligent terminal is correct according to test results.
