[0020] The working principle of this utility model is as follows: When testing the electrical cabinet, first place the electrical cabinet on the upper end of roller 2, then push the electrical cabinet to the lower end of test housing 4. Then, through the control of PLC controller 5, motor 2 796 will operate. The output shaft of motor 2 796 will drive worm 795 to rotate. Worm 795 will drive double lead screw 793 to rotate through meshing worm wheel 794. The rotation of double lead screw 793 will drive support rod 73 to move in opposite directions. Then motor 3 799 will operate. The output shaft of motor 3 799 will drive gear 798 to rotate. The rotation of gear 798 will drive support rod 74 to slide inside support rod 73 and move inward through meshing rack 797, thereby positioning and clamping the outside of the electrical cabinet. Next, by controlling the PLC controller 5, the motor 791 operates. The output shaft of the motor 791 drives the lead screw 792 to rotate. The rotation of the lead screw 792 will drive the threaded U-shaped slider 76 to move to the right. In turn, the connecting rod 78 and the U-shaped seat 77, which are connected by rotation, will drive the slide plate 71 to slide upward between the left and right inner walls of the protective box 6. In turn, the lower electrical cabinet will be moved upward through the support rod 73, the support rod 74 and the positioning plate 75. Next, the PLC controller 5 is regulated, and the robotic arm 9 operates. The robotic arm 9 will drive the test interface at the lower end of the rectangular box to contact the corresponding input port at the upper end of the electrical cabinet. Then, the multimeter 10, insulation tester 11 and oscilloscope 12 are operated. When a small current passes through the meter head of the multimeter 10, there will be a current indication. However, the meter head cannot carry a large current. Therefore, some resistors must be connected in parallel and series on the meter head to shunt or reduce the voltage, so as to measure the current, voltage and resistance in the electrical cabinet. The insulation tester 11 will test the breakdown effect of the high voltage electric field of the electrical cabinet on the insulation material. By applying high voltage, the withstand voltage of the insulation material is tested. When the oscilloscope 12 applies a DC voltage to a pair of deflection plates, it will cause the light spot to produce a fixed displacement on the fluorescent screen. The magnitude of the displacement is proportional to the applied DC voltage. If two DC voltages are applied to the vertical and horizontal pairs of deflection plates at the same time, the position of the light spot on the fluorescent screen will be determined by the displacement in both directions. In this way, the voltage, current, frequency, phase difference and modulation amplitude of the electrical cabinet will be tested.

[0021] It is worth noting that in the above embodiments, the motor 791, motor 796, motor 799, robotic arm 9, multimeter 10, insulation tester 11, and oscilloscope 12 disclosed are all of the following: motor 791 can be YEJ20.55KW-4P; motors 796 and 799 can be 35BYJ412H; robotic arm 9 can be ECO62; multimeter 10 can be Keysight3458A; insulation tester 11 can be 2500S; and oscilloscope 12 can be dsox3034a.
