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

Abstract

The invention provides an assembled transformer foundation structure and a construction method thereof, including 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, and a prefabricated oil pool side wall is installed on the base plate. The well-shaped bottom plate, the prefabricated inverted T-shaped main variable bar base is installed in the well-shaped bottom plate, and the base connecting beam is installed on the top of the prefabricated inverted T-shaped main variable bar base; the present invention utilizes the prefabricated inverted T-shaped main variable bar base to reduce The amount of concrete is used to realize prefabricated construction, which can be applied to the needs of different main transformer equipment. There are fewer wet operations on site, fewer construction procedures, and the aesthetics of the main transformer foundation completed by the overall construction 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...
