Power transformer foundation structure
The invention relates to the technical field of power transformers, and discloses a power transformer foundation structure which comprises a main stress component and an oil pool, the main stress component is used for supporting the lower side of a power transformer, the main stress component is arranged in the oil pool, a gap is formed between a pool bottom plate of the oil pool and the outer edge of the main stress component, and the main stress component is arranged in the gap. A caulking filling piece is arranged in the gap, and the caulking filling piece is attached to the edge of the pool bottom plate and the outer edge of the main stress component. The pool bottom plate of the oil pool is separated from the main stress component through the caulking filling piece, the influence of the outward extending size of the pool bottom plate of the oil pool on stress is reduced, the pool bottom plate is not in a cantilever stress type any more, reinforcement according to a cantilever plate is not needed, reinforcement and bending moment are effectively reduced, the stress of the pool bottom plate is equal to that of a uniformly-distributed load raft, and the service life of the pool bottom plate is prolonged. And the risk of crack cracking is reduced, so that the corrosion risk of steel bars in concrete is reduced, and the overall safety and durability of the structure are guaranteed.
本发明涉及电力变压器技术领域，公开了一种电力变压器基础结构，包括主受力构件和油池，所述主受力构件用于支撑于电力变压器的下侧，所述主受力构件设置于所述油池内，所述油池的池底板与所述主受力构件的外边缘之间具有缝隙，所述缝隙内设置有嵌缝填充件，所述嵌缝填充件分别与所述池底板的边缘、所述主受力构件的外边缘贴合。本发明通过嵌缝填充件将油池的池底板与主受力构件分开，减小油池的池底板外展尺寸对受力的影响，池底板不再是悬挑受力型式，无需按照悬挑板配筋，有效降低配筋和弯矩，使得池底板的受力等同于均布受荷载筏板，降低裂缝开裂的风险，从而减低混凝土内钢筋锈蚀风险，保证结构整体的安全性和耐久性。
