[0002] With the rapid development of my country's power industry, the market demand for large and extra-large transformers continues to increase. Among them, the transformer high-voltage outlet device is an important supporting device of the transformer. Its function is to improve the electric field distribution around the transformer high-voltage outlet terminal and reduce the insulation distance. Figure 1 As shown, the transformer high-voltage outlet device is generally L-shaped and has various specifications and lengths. Therefore, for large and extra-large transformers, its transportation has always been a problem. The Chinese invention patent with authorization announcement number CN103057836B discloses a transportation fixing bracket for the transformer outlet device, which includes a horizontal support member and a vertical support member arranged on a frame. The transformer outlet device is placed upright on the bracket, and one end is fixed by the vertical support member. However, the device places the transformer outlet device upright, resulting in a higher center of gravity, relatively poor stability during transportation, and prone to danger. In actual production, the best transportation state of the transformer high-voltage outlet device is still as follows. Figure 1 As shown in the flat state, the transportation center of gravity is lower, and the transportation is more stable and reliable. However, due to the various specifications of the transformer high-voltage outlet device, the lengths, corners, thicknesses, etc. on both sides of the transformer high-voltage outlet devices of different specifications are different.
