After the drone approaches the test ring on the overhead wire to be tested, the test device drives the first rotating seat, the mounting rod and the tester to rotate through the torque servo to achieve the change of the spatial position of the tester, so that the test contact of the tester is in a suitable position; then, the position of the drone is further adjusted so that the test contact of the tester can contact the test ring on the overhead wire through the rotation of the mounting rod, and then the drone is hovered; then, the torque servo drives the first rotating seat, the mounting rod and the tester to rotate so that the test contact of the tester contacts the test ring on the overhead wire, thereby realizing the contact test of the overhead wire.
