Transformer substation

Abstract

The invention discloses a transformer substation. The transformer substation is used for solving the anti-seismic problem after the center of gravity of the transformer substation is raised. The transformer substation comprises a box-type integrated transformer substation body, concrete vertical columns, auxiliary supporting supports and a self-aligning support, wherein the self-aligning support is mounted in the center of the lower bottom face of the box-type integrated transformer substation body, and the four sets of auxiliary supporting supports are symmetrically mounted at the four corners of a concrete mounting platform with the position of the self-aligning support as the center; the self-aligning support comprises an upper part, a middle part and a lower part; and the middle part comprises a first sliding plate and a second sliding plate which are overlapped from top to bottom and are in sliding fit. The transformer substation has good anti-seismic performance, wherein the self-aligning support can absorb part of seismic energy, especially the seismic energy in the horizontal direction, through friction when an earthquake occurs, and meanwhile, overall elasticity can be increased by cooperation of the auxiliary supporting 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...
