Embodiment 1

[0012] Example 1 The prefabricated basic composition of a combined box-type substation with reactive power compensation function and the role of each component:

[0013] A prefabricated assembly foundation of a combined box-type substation with reactive power compensation function, including prefabricated pillars (1), prefabricated ring beams (2), prefabricated baffles (3), and prefabricated support beams (4). The prefabricated support beam (1) is hinged to the prefabricated ring beam (2), the prefabricated support beam (4) is hinged to the prefabricated support beam (1), and the prefabricated baffle (3) ) It is connected with the prefabricated pillar (1) with a notch. The lower part of the prefabricated baffle (3) is provided with a high-voltage cable hole. The upper part of the side of the prefabricated pillar (1) is provided with ventilation holes, and the lower part is provided with a low-voltage cable hole. The prefabricated support beam (4) is provided with a lead groove...

Embodiment 2

[0014] Embodiment 2 The specific structure and connection method between the prefabricated pillar (1) and the prefabricated ring beam (2) of the prefabricated assembly foundation of a combined box-type substation with reactive power compensation function:

[0015] The prefabricated pillar (1) adopts a hollow box-shaped section form, with notches on three sides of the section, divided into three sections, each section is connected by a core column, and the upper section is left with inserts to facilitate the connection with the prefabricated ring beam (2) connection. The prefabricated ring beam (2) adopts a square cross-section and a hollow round tube is embedded inside. The column end inserts of the precast pillar (1) extend into the hole at the end of the precast ring beam (2), and then the cement mortar is used to fill it.

Abstract

A prefabricated foundation of a combination box transformer substation with a reactive compensation function comprises prefabricated stand columns (1), prefabricated ring beams (2), prefabricated baffles (3) and prefabricated supporting beams (4), and is characterized in that the prefabricated stand columns (1) and the prefabricated ring beams (2) are hinged; the prefabricated supporting beams (4) and the prefabricated stand columns (1) are hinged; the prefabricated baffles (3) and the prefabricated stand columns (1) are connected through notches. The prefabricated foundation of the combination box transformer substation with the reactive compensation function has the advantages that only installation and connection need to be carried out on site, the project building period is shortened, and the maintenance investment is reduced.

Description

technical field [0001] The invention relates to a prefabricated foundation of a combined box-type substation with a reactive power compensation function, and belongs to the technical field of electrical civil engineering. Background technique [0002] The foundation of the traditional box-type substation adopts "wet method" construction, that is, on-site pouring and masonry. This method is greatly affected by factors such as seasonal climate and personnel, and the excavation volume of earthwork is large, and the construction complexity is high. Contents of the invention [0003] The object of the present invention overcomes the deficiencies of the above technologies, and provides a prefabricated assembly foundation. The relevant components are manufactured by the manufacturer in the factory according to the general specifications, and only need to be installed after arriving at the site. The purpose of the above invention is achieved through the following technical soluti...
