[0026] The working principle and use process of the present invention:

[0027] In use:

[0028] Push the trolley 104 and use the moving wheels 102 on the base plate 101 to move the test device to a suitable test position. If the test site is large or the moving distance is long, you can also connect a traction device through the traction ring 105 to move the test device with the help of the traction device;

[0029] When the test device reaches the designated position, tighten the positioning bolts 103 near the four corners of the base plate 101 respectively, so that the bottom ends of the positioning bolts 103 are tightly pressed against the ground, and the test device is stably fixed in the position to prevent the device from moving during the test.

[0030] Start the motor 403 of the lifting structure 4, which drives the winding wheel 404 to rotate, slowly lower the lifting rope 405, and hang the converter high-voltage switch electrical device body 5 on the lifting rope 405. Adjust the direction of the lifting rope 405 by rotating the hanger 402, and place the device body stably on the fixed plate 203, so that the bottom end is pressed against the two pressure plates 301 until the anti-skid pad 305 is tightly against the side of the device body. At this time, the tension spring 308 is in a stretched state, and its tension makes the anti-skid pad 305 fit tightly against the device body. The anti-skid groove 306 increases the friction force, thereby achieving stable fixation of the device body.

[0031] According to the test requirements, loosen the limiting bolts 205 on the fixing plate 203 so that the fixing plate 203 can rotate freely on the mounting base 201 via the rotating disk 202. After the fixing plate 203 is rotated to a suitable angle, tighten the limiting bolts 205 so that the bottom ends of the limiting bolts 205 are inserted into the corresponding limiting holes 204 on the mounting base 201 to limit and fix the fixing plate 203, ensuring that the main body 5 of the converter high-voltage switch electrical device is at the required test angle;

[0032] After completing the above steps, connect the relevant lines and equipment required for the test, perform various test operations on the electrical circuit of the converter high-voltage switch electrical device body 5 according to the test procedures, and record the test data.
