It is a 220kV hub substation and a substation with a voltage level of 220kV or higher. The design elevation should be higher than the flood level or history with a frequency of 1% (recurring period, the same below) High internal water level; other voltage level substation site area design elevation should be higher than frequency The rate is 2% of the flood level or the historical highest inland water level. 8. Increased retaining wall in expansive soil area and excavated land in expansive soil area The design of the net distance from the external wall of the building (structure) to the foot support structure. 9. The allowable value of slope rate of soil excavation slope and the allowable value of slope rate of rock excavation slope are The current national standard GB 50330 "Technical Specifications for Building Slope Engineering" is coordinated. 10. Increased substations in mountainous and hilly areas, with stonework on the spot At the time, the proportion of earth and stone should be counted. 11. Increased requirements for site leveling in collapsible loess areas. 12. The cable gland cover can be added to use the finished cover. 13. The “Overhead Pipeline” section has been removed. 14. Increased special soil sites such as expansive soil areas and collapsible loess areas Use urban roads inside the station. 15. In accordance with the current national standard GB 50016 "Code for Fire Protection of Building Design" Therefore, this revision will change the net width of the main circular fire lane of the substation from 3.5m to 4m. 16. Increased the width and turning radius of the high-voltage reactors in the station. 17. Revised the coverage protection method for outdoor power distribution equipment. 18. Eliminated the land area and station within the fence of the living area in the main technical and economic indicators. The greening area of the district, the greening land coefficient of the station area and the calculation method of its indicators. This standard replaces DL/T 5056-1996 after implementation.
