Intelligent testing method for mutual inductor

An intelligent testing method for a mutual inductor belongs to the technical field of mutual inductors, and comprises the following specific test operation processes: in assembly line work, transferring an assembled finished mutual inductor to a special tray, transferring the finished mutual inductor to the head end of a test line by using an electric vehicle, and sequentially carrying out the following steps: S1, carrying out a voltage withstanding test; s2, partial discharge detection; s3, pressing a forward button to a next station, and carrying out a direct current resistance measurement test; s4, carrying out an insulation resistance measurement test; s5, a forward button is pressed to a next station, and polarity and accuracy inspection tests are carried out; s6, performing excitation characteristic detection test; and after the report card certification is printed, tying the report card certification on a mutual inductor and transferring the report card certification to a package and warehousing by an
