[0002] The substation is a key facility in the power system for transforming voltage, accepting and distributing electric energy, and controlling power flow, and its construction involves the combined installation of multiple types of equipment and systems. The substation is mainly composed of transformers, switchgear, busbars, relay protection devices, measuring instruments, etc., among which the voltage transformer plays an indispensable role in the substation. It can transform high voltage into low voltage in proportion to provide voltage signals for secondary devices such as measuring instruments and relay protection devices, so that these devices can accurately monitor and protect the operation of the power system.

Figure 2 3 Specifically, as shown in the drawings, the lifting assembly 2 comprises support arms 21, a support cylinder 22, a reinforcing plate 23, a mounting plate 24, a hydraulic rod 25, and a lifting cylinder 26. Two support arms 21 are provided, and the bottom ends of the two support arms 21 are both installed with pulleys and adjustable feet. The top ends of the support arms 21 are fixedly installed through the reinforcing plate 23. The support cylinder 22 is fixedly installed on the reinforcing plate 23. The side wall of the reinforcing plate 23 is fixedly connected with the mounting plate 24. The lifting cylinder 26 is slidably installed in the support cylinder 22.

The top end of the hydraulic rod 25 is hingedly installed on the side wall of the lifting cylinder 26. Two ends of the cross beam 3 are fixedly installed with the top surfaces of the lifting cylinders 26.​

[0050] When the height of the cross beam 3 needs to be adjusted, the hydraulic rod 25 starts to work. The tail of the hydraulic rod 25 is hinged to the top surface of the mounting plate 24, and the top end is hinged to the side wall of the lifting cylinder 26. The piston inside the hydraulic rod 25 extends and retracts under the action of hydraulic oil pressure, pushing the lifting cylinder 26 to slide up and down in the supporting cylinder 22, adjusting the height of the cross beam 3 to adapt to the installation requirements of the transformer substation voltage transformer 1 at different heights, and facilitating the construction personnel to install the voltage transformer 1 to the appropriate height.

[0053] After the first driving motor 45 is started, the synchronous wheel 44 connected with it is driven to rotate, and the synchronous belt 43 is driven to rotate when the synchronous wheel 44 rotates. Because the inner side of the first sliding seat 41 is fixedly installed with the synchronous belt 43, and the inner side of the first sliding seat 41 slides on the slide rail 42, the transmission of the synchronous belt 43 will drive the first sliding seat 41 to slide on the slide rail 42 on both sides of the cross beam 3.

[0058] Rotating the hand wheel 61 drives the first threaded rod 62 to rotate. Since the side wall of the first threaded rod 62 is threadedly connected with the side wall of the mounting disc 53, the rotation of the first threaded rod 62 will drive the second sliding base 64 to move axially. The other end of the first threaded rod 62 is rotatably connected with the second sliding base 64 through the bearing seat 63. When the first threaded rod 62 rotates, it drives the second sliding base 64 to slide radially in the first sliding groove 54 and the second sliding groove 55.
