The adjusting component 21 is connected to the fixing mechanism 22, the adjusting component 21 is connected to the equipment main body 1, and the fixing mechanism 22 is connected to the locking component 3.

[0035] When the connection lines on the transformer need to be removed for maintenance, the overall lines are adjusted upward through the adjusting component 21, and the fixing mechanism 22 is locked through the locking component 3, thereby fixing the adjusting component 21, realizing the up-and-down adjustment of the lines, facilitating the maintenance of the transformer, and enabling the replacement of busbars of different sizes.

[0036] Embodiment 2

[0037] As Figures 1-7 shown, as a preferred embodiment of the present utility model, the equipment main body 1 includes a housing 11 and a transformer placement table 12, and the transformer placement table 12 is fixedly installed on the inner bottom wall of the housing 11. Among them, both the adjusting component 21 and the locking component 3 are installed on the housing 11, and the transformer placement table 12 is connected to the adjusting component 21.

[0038] The adjusting assembly 21 includes an installation groove 211, a first slide rail 212, an electric cylinder 213, a busbar mounting block 214, a second slide rail 215, a clamping plate 216, and a spring 217. A plurality of installation grooves 211 are equidistantly formed at the top of the rear side of the housing 11. There are two first slide rails 212 which are respectively located on both sides of the installation groove 211. The two first slide rails 212 are fixedly installed at the top of the rear side inside the housing 11. The electric cylinder 213 is fixedly installed at the top of the rear side of the transformer placement table 12. A busbar is installed on the busbar mounting block 214, and the busbar is connected to an external circuit. Both sides of the busbar mounting block 214 are slidably connected to the two first slide rails 212 respectively. The output end of the electric cylinder 213 is fixedly connected to the bottom of the busbar mounting block 214. There are two second slide rails 215 which are both fixedly installed on the outer wall of the rear side of the housing 11. The two second slide rails 215 are respectively located on both sides of the installation groove 211. There are two clamping plates 216 which are respectively located on the upper and lower sides between the two second slide rails 215. Both sides of each clamping plate 216 are slidably connected to the two second slide rails 215 respectively. Two springs 217 are fixedly connected between the opposite side surfaces of the two clamping plates 216, and the two springs 217 are respectively arranged on the left and right sides of 216. Among them, the clamping plate 216 is connected to the fixing mechanism 22.
