Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-6 The utility model provides a technical solution: an auxiliary device for a high-voltage motor withstand voltage tester, including a base 1, which is a circular plate structure.

Legs are fixedly connected to the four corners of the bottom of the pressure tester body 5, and the four legs are respectively clamped in the four connecting grooves 10.

[0030] It should be noted that when the utility model is used, the withstand voltage tester body 5 is installed on the support plate 4. During installation, the distance between the two sliders 8 is adjusted according to the distance between the ends of the two supporting feet at the two ends of the bottom of the withstand voltage tester body 5. During adjustment, the knob 11 is turned to rotate the bidirectional screw 7, and the two sliders 8 are moved away from each other through the threaded connection between the two sliders 8 and the two ends of the bidirectional screw 7. Then, the ends of the supporting feet at the two ends of the bottom of the withstand voltage tester body 5 are respectively inserted into the connecting grooves 10 on the two sliders 8, and then the knob 11 is rotated in the opposite direction to slowly move the two sliders 8 closer until the supporting legs at the two ends of the bottom of the withstand voltage tester body 5 are completely inserted into the connecting grooves 10. At this time, the bottom of the withstand voltage tester body 5 contacts the surface of the support plate 4, and then the nut on the fixing plate 20 is adjusted to make the two top plates 23 press against the two sides of the withstand voltage tester body 5 to make the position of the withstand voltage tester body 5 The device is placed firmly, and then pushed to move to the high-voltage motor to be tested.
