Abstract：Through the comparative analysis of main electrical wiring schemes of a large stadium,substation location and load rate of a transformer in different operating modes,the key points of electrical design were summarized,such as load classification,

power supply and self‑contained power,grid roofing channels on the cable tray system,lightning protection and grounding of a large stadium,and the matters to be highlighted and corresponding measures were put forward in terms of requirements for performance,public welfare and operating modes in the electrical design process of large stadiums.

Key words：load classification;self‑contained power;main electrical wiring;performance requirements;public welfare requirements;operating modes;transformer load rate;lightning protection and grounding

摘　要：通过对比分析大型体育场的电气主接线方案、变电所设置位置、各种运营模式下的变压器负载率等，归纳总结大型体育场负荷分级、供电电源及自备电源、电缆桥架上网架屋面通道、防雷接地等电气设计要点，提出大型体育场电气设计过程中针对演艺需求、公益需求及运营模式需要重点关注的事项及应对措施。
