Under the backdrop of the State Grid Corporation's proposal of a global source Internet, Sun Lin, a power engineer from Panjin Power Supply Company in Liaoning Province, innovated a new "ring-shaped radial GIS substation structure layout" through 3D printing technology. The invented new "Radial GIS substation structure layout" can meet the requirements of distributed energy, flexible access and operation of power supply, and build an "innovative, coordinated, green, open and shared" energy network for the State Grid. (Figure 1) conventional GIS substation distributed energy overhead lines crossing across the structure of the network diagram (Figure 2) to build a ring-shaped radial GIS substation as the center of a hybrid transmission and distribution network In Fig. 2, 1, 2, 3 and 4 are the layout of the large ring network of the conventional substation, 5,6,7 are the layout structure of the distributed energy network, and 8, 9, 10, 11 and 12 are substations of low-voltage user-supplied power. The layout structure of the existing GIS substation covers an area of ​​2/3, eliminating the high-voltage transmission overhead lines crossing staggered structure, effectively saving the power transmission substation peripheral part of the corridor area, beautify the environment while saving a lot The capital investment.
