[0034] The working principle is as follows: Install the device to be detected on the mounting base 5, and control the clamping plate 8 to clamp and fix it through the fixed electric cylinder 7; Connect the device to be detected with the electrical docking part 15 on the measurement box 6 through a wire for power-on measurement; Specifically, the electrical variable detection results are displayed through the display control board 14, that is, the electrical variables such as voltage, current, power, electric energy, and harmonic analysis of the product to be detected are measured; The device to be detected can be cooled through the cooling air box 4; Further, by the operation of the first motor 2, the first lead screw 3 rotates, causing the moving seat 9 to move, and then the shaking electric cylinder 10 moves to the lower part of the mounting base 5. The shaking electric cylinder 10 controls the movement of the fixing part 11, so that the fixing part 11 cooperates with the first mating seat 501, and the electromagnetic mating shaft 12 mates with the mating hole on the first mating seat 501 to fix the mounting base 5; The shaking electric cylinder 10 controls the mounting base 5 to shake up and down, so that the product to be detected shakes, and then the stability and changes of the electrical variable parameters of the device to be detected under the shaking condition are measured. During shaking, the device to be detected is in a fixed state, moves synchronously with the mounting base 5, and there is no impact between them, and the device to be detected will not be damaged.

[0035] For the protection operation, when not working, the protection adsorption part 17 is docked and cooperated with the electrical docking part 15 to shield and protect the electrical docking part 15 to prevent dust accumulation; Further, when the protection adsorption part 17 is outside the electrical docking part 15, through the operation of the protection adsorption box 16, the protection adsorption part 17 performs an adsorption operation, and the residual impurities inside the electrical docking part 15 can be adsorbed to remove the impurities; Ensure stable subsequent connection.

[0036] Further, the mating bottom column 602 at the bottom of the measurement box 6 is cooperatively installed on the second mounting part 102 and fixed by the electromagnetic mating shaft 12; The moving seat 9 moves to the lower part of the measurement box 6, and the shaking electric cylinder 10 controls the movement of the fixing part 11. The fixing part 11 cooperates with the second mating seat 601, and the electromagnetic mating shaft 12 fixes the measurement box 6. Then the electromagnetic mating shaft 12 releases the fixation of the mating bottom column 602, and the shaking electric cylinder 10 controls the measurement box 6 to shake up and down, which can assist in shaking off the internal dust accumulation and improve the efficiency of dust removal. It should be noted that when the measurement box 6 is shaken, the protection adsorption part 17 is disengaged from the electrical docking part 15.

[0037] When dust removal is carried out inside the measurement box 6, the drive motor 2801 operates to rotate the rotating ring 28. When the toothed disc 35 follows the rotation of the rotating ring 28 and meshes with the fixed toothed ring 30, the toothed disc 35 rotates itself. Under the connection of the eccentric rod 34 and the second connecting rod 33, the first sliding seat 32 reciprocates. And under the connection of the first connecting rod 31, the deflecting adsorption cylinder 29 reciprocates and deflects, thereby performing deflecting adsorption inside the measurement box 6, that is, the dust removal adsorption box 27 operates, and the dust accumulated inside the measurement box 6 is adsorbed and transmitted to the dust removal adsorption box 27 through the deflecting adsorption cylinder 29, the rotating ring 28, and the connecting ring 26 to complete the dust removal operation.
