[0002] A high-voltage transformer refers to a transformer that converts low voltage into high voltage through the principle of electromagnetic induction. It is an important component of the power system. The high-voltage transformer is mainly installed on a support frame between two outdoor electric poles through fixed equipment. Its main function is to convert and transmit electric energy, thereby achieving voltage and current stabilization for the power system and ensuring the normal operation of the circuit.
[0003] Based on the above, the inventors found that: when the existing fixing equipment is in use, the transformer and the support frame are fixedly connected mainly by bolts in cooperation with the base, but the connection position is completely exposed to the outside and lacks a protective structure. After a long time, corrosion and rust are prone to occur, affecting the stability of the transformer. Therefore, in view of this, the existing structure is studied and improved, and a fixing device for high-voltage transformers is provided, in order to achieve a more practical purpose.

[0010] Furthermore, the connection between the protective cover and the ball slider passes through the side of the transformer body, and the protective cover and the mounting seat are snap-connected.
[0011] Furthermore, the positioning block is located inside the corresponding protective cover, and the positioning block and the outer handle are both slidably connected to the corresponding protective cover, and the positioning block is adapted to the positioning groove.
[0012] Furthermore, the clamping plate is clamped with the adjacent protective cover, and the two ends of the self-locking spring are fixedly connected with the positioning block and the inner surface of the protective cover respectively.

First, the transformer body 1 is moved to the support frame between the two electric poles, and the transformer body 1 is fixedly connected by passing bolts through the mounting seat 2.
[0023] See also Figure 4 The self-locking mechanism 4 includes an outer handle 11, both ends of the outer handle 11 are fixedly connected with positioning blocks 12, and both ends of the outer handle 11 are sleeved with self-locking springs 14 on the outside, and a pressure surface 13 is provided on one side of the positioning block 12. In order to ensure the connection stability of the two protective covers 3 and reduce the occurrence of looseness problems, the protective covers 3 can effectively protect the fixed position of the transformer, and a self-locking mechanism 4 is provided.
[0024] See also Figure 3 The screw rod 8 is located inside the transformer body 1, and the screw rod 8 is movably connected to the transformer body 1. The limit ring 9 is located outside the transformer body 1. The screw rod 8 is driven to rotate by the hand rod 10, and the two limit rings 9 are used to ensure the rotation stability of the screw rod 8.
[0025] See also Figure 3Two rotating threads of the same length and opposite directions are provided on the outside of the screw rod 8, and the two rotating threads are respectively matched with the two ball sliders 7. The two rotating threads cooperate with each other, so that the rotation of the screw rod 8 drives the two ball sliders 7 to move synchronously in the opposite direction, thereby driving the protective cover 3.
[0026] See also Figure 3 The connection between the protective cover 3 and the ball slider 7 passes through the side of the transformer body 1, and the protective cover 3 and the mounting seat 2 are snap-connected. When the two protective covers 3 are snap-fitted, the connection between the mounting seat 2 and the support frame is sealed, reducing the corrosion and rust problem at the connection of the mounting seat 2.
[0027] See also Figure 4 The positioning block 12 is located inside the corresponding protective cover 3, and the positioning block 12 and the outer handle 11 are both slidably connected to the corresponding protective cover 3. The positioning block 12 is adapted to the positioning groove 6. The clamping plate 5 contacts the pressure surface 13 during movement, thereby squeezing the positioning block 12 and the outer handle 11 to slide outward.

Corrosion and rust problems, at the same time, the movement of the two protective covers 3 makes the clamping plate 5 enter the adjacent protective cover 3, and the clamping plate 5 contacts the pressure surface 13 during the movement, thereby squeezing the positioning block 12 and the outer handle 11 to slide outward, and at the same time, the positioning block 12 squeezes the self-locking spring 14 to contract until the positioning groove 6 on one side of the clamping plate 5 moves to the same position of the positioning block 12, under the action of the self-locking spring 14, the positioning block 12 and the outer handle 11, the positioning block 12 and the positioning groove 6 are clamped, and then the two protective covers 3 are fixed in position by the clamping plate 5.
