TECHNICAL FIELD
[0001] The utility model belongs to ASA transformer transportation field relates to a kind of coil transport positioning device suitable for ASA project. BACKGROUND
[0002] High-voltage, large-capacity transformers are increasingly used in power grids due to their long-distance power transmission and low energy consumption per unit capacity. With the significant increase in the capacity of individual transformers, their weight and volume also increase, making it difficult to transport large-capacity transformers as a whole in many areas with poor traffic conditions or complex terrain, such as mountainous regions. Therefore, developing large-capacity transformers that can meet existing transportation conditions has become one of the bottleneck problems for further technological development.
[0003] To meet the demand for long-distance, large-capacity power transmission, ASA (Advanced Site Assembly) is used to reasonably decompose the main structural parts of the transformer into several transportation units to reduce the weight of each transportation unit. Due to the limitations of transportation size and weight, the ASA project requires the product to be disassembled into sub-components for transportation after the test is completed. The assembled coil is disassembled and packed into the coil transport cylinder by pressing the assembly plate, and the coil and transport cylinder are fixed by the positioning device to prevent the coil from moving in the cylinder during transportation.
[0004] As provided in the existing technology, the announcement number CN201559907U of Chinese utility model patent provides a combined adjustable sleeve coil transport box, which includes a lower section transport box, a transport box adjusting and lifting seat, an upper section transport box, a pull screw, an adjustable support cylinder, an inner support cylinder, a pressing plate, a pressing pad, and a complete set of coils. The lower section transport box, the transport box adjusting and lifting seat, and the upper section transport box are connected from bottom to top, forming a height-adjustable overall transport box. The adjustable support cylinder and the inner support cylinder are matched inside the box. The complete set of coils is placed inside the transport box and outside the adjustable support cylinder. The complete set of coils is provided with a pressing pad and a pressing plate, which are fixed together with the lower section transport box by a pull screw. However, the above structure adopts an integrated design, which lacks sufficient flexibility to adapt to deformation during long-term use. Initially, the screw position is fixed for connecting and supporting the coil. However, as the transport cylinder deforms, the relative position between the screw and the transport cylinder may change. The deformation of the transport cylinder causes the screw to deviate from the originally designed fixed position, affecting the fixation effect of the coil and the stability during transportation. The deviation of the fixed position may cause the coil to loosen during transportation, or even collide with the inner wall of the transport cylinder or other components, causing damage to the coil.
