[0038] Working principle: A DC withstand voltage test can be performed by connecting the external cable head to the generator body 511 through the line inlet 4. When the temperature of the generator body 511 is too high during operation, the operation of the liquid pump 209 and the condenser 211 can be turned on, so that the liquid pump 209 can effectively drive the working fluid inside the condenser tube 208 to circulate.

The telescopic rod 502 is rotated by rotating the limit handle 501. The rotation of the telescopic rod 502 drives the bidirectional threaded rod 503 to rotate. The rotation of the bidirectional threaded rod 503 drives the upper clamping plate 504 and the lower clamping plate 507 to approach each other until the upper clamping plate 504 contacts the generator body 511 to fix it. Through the coordinated setting of hydraulic rod 1 505, spring 1 506, hydraulic rod 2 509 and spring 2 510, when the device encounters some external collisions that cause it to fall, the inertia of the contraction and rebound of hydraulic rod 1 505 and spring 2 510 can effectively buffer some of the harsh shaking, so that the upper clamping plate 504 and the lower clamping plate 507 can clamp the generator body 511 more stably. By pulling the pull rod 6 to tilt the protective box 1, and cooperating with the rolling of the moving wheel 7, the device can be moved more conveniently, further making the device more flexible.
