Fabricated transformer foundation structure and construction method thereof

Abstract

The invention provides a fabricated transformer foundation structure and a construction method thereof. The fabricated transformer foundation structure comprises an oil pool foundation pit, a base plate is arranged in the oil pool foundation pit, a prefabricated oil pool side wall is installed on the side of the oil pool foundation pit, a #-shaped bottom plate is installed on the base plate, prefabricated inverted-T-shaped main transformer strip bases are installed in the #-shaped bottom plate, a foundation connecting beam is installed at the tops of the prefabricated inverted-T-shaped main transformer strip bases. The prefabricated inverted-T-shaped structure main transformer strip bases are used for reducing concrete consumption, fabricated construction is achieved, the fabricated transformer foundation structure can meet the requirements of different main transformer devices, the number of on-site wet operation is small, the number of construction procedures is small, the attractiveness of an integrally-constructed main transformer foundation is greatly improved, and the construction quality is easy to control.

Description

technical field [0001] The invention relates to the technical field of transformer foundations, in particular to an assembled transformer foundation structure and a construction method thereof. Background technique [0002] In recent years, in line with the purpose of building a "resource-saving and environment-friendly" society, the State Grid Corporation has vigorously implemented intensive management, standardized construction, unified engineering construction standards, reasonable cost control, and transformed power grid development methods. The technical level, layout and cost of the substation are mainly affected by the main electrical primary equipment, mainly including 110~500kV substation transformers, high-voltage shunt reactors, combined electrical appliances (GIS, HGIS), circuit breakers and other 12 types of equipment. General Equipment for Power Transmission and Transformation Projects of State Grid Corporation, this book not only regulates the parameters of el...

AI Technical Summary

Problems solved by technology

[0005] In view of the fact that the current transformer foundation is a whole-slab foundation, the bottom plate and the strip foundation are all made of reinforced concrete, and the whole adopts the cast-in-place wet method. Temperature deformation occurs, cracks are easy to occur, and once the construction is completed, the size of the foundation beam cannot be adjusted, the subsequent expansion of transformer capacity is difficult, and the technical problems of large construction investment, the present invention proposes a prefabricated transformer foundation structure and its construction method
