Example Embodiment

[0057] like figure 1 and Figure 16 As shown, the present invention provides a single-column seismic substation, including a box-type integrated substation 7, a concrete column 91, an auxiliary support bearing 8 and an aligning bearing A, wherein the lower end of the concrete column is inserted into the foundation to meet the seismic intensity of 8 building requirements. The upper part of the concrete column extends to at least 3 meters above the ground, and a concrete installation platform 92 is formed on the top of the concrete column by pouring, wherein the concrete column is located at the center of the concrete installation platform. As the height of the box-type integrated substation itself increases and the center of gravity moves up, higher requirements for seismic performance are put forward.

[0058] The auxiliary support supports 8 are installed at the four corners of the box-type integrated substation, and are respectively elastically connected to the four corner...

Abstract

The invention discloses a single-column anti-seismic transformer substation used for achieving seismic resistance after the gravity center of the transformer substation rises. The transformer substation comprises a box type integrated transformer substation body, concrete stand columns, auxiliary supports and a center regulating support, wherein the center regulating support is installed in the middle of the lower bottom surface of the box type integrated transformer substation body, and four sets of auxiliary supports are symmetrically installed at four corners of a concrete installation platform with the center regulating support as the center; the center regulating support comprises an upper part, a middle part and a lower part, the middle part comprises a first sliding plate and a second sliding plate which are stacked from top to bottom, and sliding fit is achieved between the first sliding plate and the second sliding plate. The transformer substation has high anti-seismic performance; the center regulating support can absorb part of seismic energy, especially seismic energy in the horizontal direction, through friction when an earthquake occurs; meanwhile, overall elasticity can be improved through cooperation of the center regulating support and the auxiliary supports.

Description

technical field [0001] The invention relates to a box-type substation, especially an overhead box-type substation. Background technique [0002] Box-type substations are widely used power equipment in the construction and transformation of power system urban networks. With the frequent occurrence of natural disasters in recent years, strong earthquakes have occurred in Wenchuan, Yushu and Japan. Due to structural design problems, the existing substations cannot Earthquake resistance, and once the substation equipment is damaged in the earthquake, not only the economic loss is huge, but also the self-rescue and life of the people in the disaster area will be seriously affected. At the same time, the European or American box-type substations currently introduced in my country are all set on the ground , Occupy a large amount of urban road area, hinder traffic, easily cause accidents, and the large size hinders the operation of nearby shops. [0003] In view of this problem, how...
