The distribution transformer is an important accessory in a power grid system, the quality of the distribution transformer is directly related to the running safety performance of a power system, a direct-current resistance test and a transformation ratio test of the transformer are important links in transformer quality inspection and are indispensable test items in a factory test, the direct-current resistance test can be used for inspecting the welding quality of a winding joint and whether turn-to-turn short circuit occurs between windings, whether contact of each position of a voltage tap switch is good and whether actual positions of tapping are consistent, whether the lead wire is broken or not and the like are detected, and whether the tapping position of the transformer is in a qualified range is detected in the transformation ratio test.
When a transformer manufacturer carries out a direct current resistance test of a distribution transformer at the present stage, a tester needs to manually switch test clamps in sequence to achieve the results of measurement at different positions, and the direct current resistance test needs to check different phase resistances at each tapping position, so that the tester needs to repeatedly switch the positions of the test clamps during the test, and the tester occupies the test time of the tester greatly. For example, in a normal five-tap transformer, low voltage needs to be manually switched for six times in a test, high voltage needs to be manually switched for fifteen times to complete the test, and after each test is completed, a tester needs to manually record test data and manually calculate the unevenness of the direct current resistance, so that a recording error is easily caused in the test data recording process. In the transformation ratio test, the direct current resistance measuring wire needs to be dismantled and connected again to the transformation ratio measuring wire, the position of the tap changer is adjusted five times, and data after the test still needs to be recorded manually.
