500kV platform type indoor substation power distribution device building structure

Abstract

The invention provides a 500kV platform type indoor substation power distribution device building structure, comprising a first layer platform, a second layer platform, a third layer platform, a fourth layer platform and a fifth layer of which are set from bottom to top. A 66kV capacitor bank is mounted on the first layer platform. A 66kV GIS and a 500kV main transformer are mounted on the third layer platform. A 220kV GIS is mounted on the fourth layer platform. A 500kV GIS is mounted on the fifth layer platform. A cable interlayer is formed between the second layer platform and the third layer platform. The 500kV main transformer is electrically connected with the 66kV GIS, the 220kV GIS and the 500kV GIS. The 66kV capacitor bank is electrically connected with the 66kV GIS. Compared witha conventional 500kV indoor substation, the structure has the advantages that on the premise of satisfying function requirements of the 500kV indoor substation, construction height of a 500kV indoorsubstation power distribution device building can be limited within a range satisfying regulations and requirements of a city plan, floor space of the 500kV indoor substation is greatly reduced, a land resource utilization rate is improved, and investment cost is reduced.

Description

technical field [0001] The invention relates to the field of power distribution structure design of a 500kV indoor substation, in particular to a 500kV platform type indoor substation power distribution device building structure. Background technique [0002] With the development of the city, the city's power load has grown rapidly, and a large number of high-voltage substations have been built in the urban center. [0003] However, since urban land resources are very precious and land is a non-renewable resource, if the conventional outdoor substation configuration method is adopted, it will not only lead to a large increase in the amount of land used for substations, but will inevitably cause unnecessary waste of urban land resources, and it is easy to use The limit value of substation building height cannot meet the regulations and requirements of urban planning in the area, especially the construction of high-voltage substations in urban areas will inevitably lead to exc...

[0003] However, since urban land resources are very precious and land is a non-renewable resource, if the conventional outdoor substation configuration method is adopted, it will not only lead to a large increase in the amount of land used for substations, but will inevitably cause unnecessary waste of urban land resources, and it is easy to use The limit value of substation building height cannot meet the regulations and requirements of urban planning in the area, especially the construction of high-voltage substations in urban areas will inevitably lead to excessive excavation of earth and stone. The influence and constraints of these unfavorable factors will inevitably lead to The overall investment cost of the substation increases
