7项成都世运会保电重点项目全力冲刺建设 预计迎峰度夏前投运

Core Viewpoint - The completion of key construction work for the 220 kV power transmission and transformation project in Chengdu Airport New City marks significant progress towards ensuring power supply for the 2025 World Games in Chengdu, with the project entering its final phase of construction [1][3]. Group 1: Project Overview - The 220 kV substation project began construction in March 2024 and is currently in the electrical equipment debugging phase, expected to be operational before the summer peak [1][3]. - The project is one of ten major power supply projects for the 2025 World Games, with seven projects managed by State Grid Chengdu Power Supply Company [3]. Group 2: Technological Innovations - Advanced technologies such as sulfur hexafluoride and high-purity nitrogen are used in closed combination electrical equipment to ensure safe power transmission [3]. - The project incorporates sensors and cameras to monitor electricity usage and line operation conditions, allowing for immediate switching to backup lines in case of faults [3]. Group 3: Construction Challenges - The construction faces significant challenges, including multiple crossings over highways, subways, and high-voltage lines, necessitating the use of drones and mechanized crossing frameworks to enhance safety and efficiency [4]. - Comprehensive safety measures and emergency plans have been developed, including infrared temperature measurements and grounding resistance tests for direct power supply lines and substations [4]. Group 4: Impact on Infrastructure - Once operational, the project will significantly enhance the power supply capacity for critical facilities such as airports, high-speed rail, and subways, addressing the growing electricity demand in Chengdu's Eastern New District [4].
