　　摘要：对于特级或一级体育场，应急电视转播需要应急电源为场地照明供电。我们通过对四种品牌2000W/380V金属卤化物投光灯的试验、测量、数据分析，得出场地照明用应急电源装置(EPF)必须具备的主要特性：第一，EPF的切换时间长短不能保证在电源转换时金属卤化物灯不熄灭，除非切换时间为零;第二，金属卤化物灯具有不大于2倍额定电流，启动时间长于2分钟的启动特性，EPF应能承受此冲击;第三，灯端电压变化对金属卤化物灯光输出有很大的影响;第四，EPF供电时间大于10分钟即可。据此，本文提出了场地照明应急电源装置EPF的参数要求。

　　Abstract[LiBH1] : For a A+ class or A class stadium, the emergency power supply required by emergency TV broadcasting should provide power for emergency lighting. Through our tests, measurement and data analysis of four brands of metal halide lamps with 2000W/380V, we get the main features of emergency power facility for field lighting (EPF) as follows: Firstly, the switching time of EPF cannot ensure the light continuity of metal halide lamp during the power switching, as long as the switching time can not reach zero. Secondly, metal halide lamps should be no more than twice of the rated current value and yet longer than 2 minutes of start time, which EPF should endure. Thirdly, the voltage variation of lamp has great influence on the light output of the metal halide lamp. Over 10 minutes of EPF power supply time should be acceptable. Based on this, we bring forward the working principle and parameter requirements of EPF. Fourthly, because EPF will only be applied during power switching and the switching time of power supply is only a few seconds, in principle, over 10 minutes of EPF power supply time should be acceptable. Based on this, we bring forward the working principle and parameter requirements of EPF.
