Background art:

the objective difference of the product technical schemes of various GIS equipment suppliers in China does not form a unified, detailed and available GIS equipment basic embedded part standard at present, and the application effect of the GIS equipment basic embedded part in general equipment is not ideal, so that the further improvement of the general interchangeability of GIS equipment is restricted. Therefore, the research is accelerated to form a uniform and standard GIS equipment foundation embedded part scheme, which is a necessary condition for continuously promoting the modular construction level of the transformer substation. The defects of the existing GIS equipment embedded part scheme are as follows:

1. at least 5-8 months are needed from the preliminary design scheme to the construction of the foundation and the embedded parts of the GIS equipment by a construction unit, and the construction progress of the foundation embedded parts of the GIS equipment greatly restricts the efficiency of engineering construction.

2. For an indoor transformer substation, basic embedded parts of the distant view equipment are constructed once, so that the equipment with the same model needs to be purchased during the distant view extension. Due to the limitation of models, a conventional bidding form cannot be adopted, and the purchasing cost cannot be effectively controlled.

3. The existing equipment foundation embedded parts are all poured at one time, the positioning requirements on the embedded parts are extremely high, later-stage hoisting of equipment is often influenced by factors such as construction errors, and even potential safety hazards are caused to safe operation of GIS equipment.

4. Along with the development of electrical equipment of a transformer substation, the depth of a cable trench required by electrical specialties is gradually deepened, so that the height of a lightweight concrete surface layer above a GIS room structure layer is raised. In the construction process of the transformer substation at the present stage, the concrete surface layer poured for the second time is generally larger than 300mm, and the thickness of the surface layer is thick, so that the transverse embedded parts are arranged, and reinforcing mesh sheets, cables, pipelines and the like of the lightweight concrete surface layer cannot penetrate through the concrete surface layer, so that inconvenience is brought to site construction. During field construction, the reinforcing mesh is generally cut off at the blocking position of the transverse line embedded part, so that the anti-cracking capacity of the lightweight concrete surface layer is reduced, and the lightweight concrete surface layer can crack under long-term operation of a transformer substation, so that potential safety hazards are brought to operation and maintenance.
