The invention relates to square radial GIS (gas insulated switchgear) transformer substation structure arrangement comprising an upper operation platform and a lower operation platform. Each of the upper operation platform and the lower operation platform is of a square hollow structure, and platform support columns are arranged between the upper operation platform and the lower operation platform. A framework is arranged on the upper operation platform, and insulator strings are hung on the framework. Buses are laid on the upper operation platform and the lower operation platform. A reserved gap exit is mounted on each section of bus, and a fracture is formed in each of two ends of each layer of buses. An upper high-voltage combined appliance and a lower low-voltage combined appliance are in staggered and layered arrangement. A GIS transformer substation master control building and a capacitor set chamber are arranged in a hollow position of a square platform. The square radial GIS transformer substation structure arrangement meets basic electric design requirements of equipment transportation, installation, overhauling, testing and the like and related maintenance regulations, occupied area is decreased by half, and the adopted flexible and layered wire inlet and outlet design is more suitable for construction and management of the new generation of intelligent power grids.
Description
technical field [0001] The invention relates to a novel layout design of a GIS substation, in particular to the structural layout of a square radial GIS substation, and belongs to the technical field of electrical layout design. Background technique [0002] At present, large-scale GIS substation equipment at home and abroad all abide by the design principles of traditional substation electrical main wiring. For example, most of the 110kV and 220kV GIS equipment in large-scale hub substations use the wiring method of single busbar segment or double busbar segment. Single-bus section wiring is simple, economical, and convenient, and is suitable for substations with 110kV and 220kV feeders with 4 circuits; double-bus section wiring can take turns to overhaul buses, flexible scheduling, convenient expansion, and convenient for testing, suitable for 110kV, 220kV Substations with more than 6 feeders. [0003] The layout of GIS equipment generally adopts outdoor horizontal arran...
