Description

Technical Field

[0001] The invention relates to the technical field of power transformer radiator pipeline processing, and in particular to a device and method for integrally assembling a power transformer radiator. Background Art

[0002] When a large oil-immersed power transformer is in operation, it is generally necessary to install an external plate radiator to dissipate the heat from the transformer oil inside the transformer to reduce the operating temperature and ensure safe operation of the transformer.

[0003] The existing plate radiator is installed on the oil collecting pipe leading out from the outside of the transformer oil tank. The traditional assembly and manufacturing process of the collecting pipe is to assemble the lower collecting pipe, the supporting pipe, the upper collecting pipe, etc. from bottom to top with the transformer oil tank interface. This assembly and manufacturing process has the problems of long high-altitude working time, long-term occupation of the overhead crane, and low work efficiency.

[0004] In view of the problems of long aerial work time and long-term occupation of overhead crane and low work efficiency in the existing assembly and production process, the device for overall assembly of power transformer radiator is assembled on the ground, which greatly reduces the risk of aerial work and ensures the safety of workers. At the same time, assembly on the ground platform can more conveniently perform alignment, adjustment of spacing, diagonal size, straightness, verticality and other parameters, and can more efficiently perform welding and lifting operations, simplifying the assembly process of the converging oil pipeline, making the assembly process simpler and more efficient, thereby improving the efficiency of assembly work. Summary of the invention
