摘要
介绍广州国际体育演艺中心电气设计的难点:①变压器平时负荷率很低,空载损耗大;②金属卤化物灯熄灭后重启时间长;③比赛大厅火灾探测器的选择。提出解决办法。
Some difficulties found during the electrical design for Guangzhou International Sports Arena are introduced and corresponding solutions are offered in this paper： （1） as the load rate is very low usually, the no-load loss of transformer is high; （2） the metal halide lamp needs a long time to restart after turning off; （3） the choice for fire detector in competition hall.
