摘　　要：随着电子科技的飞速发展,LED电子显示屏在各领域均得到广泛应用。LED显示屏属于非线性用电设备,使用时会产生谐波电流并给供配电网造成谐波污染,严重时会引发火灾。本文通过对大型活动现场LED显示屏系统的测试验证,揭示其引发火灾的机理,并提出针对性的防控措施及应急处置方法。With the rapid development of electronic technology,LED electronic display screen has been widely used in various fields.LED display screen is a non-linear electrical equipment,which will generate harmonic current and cause harmonic pollution to power supply and distribution grid when used,and will cause fire in serious cases.Through the test and verification of LED display screen system in large-scale event site,this paper reveals the mechanism of fire,and puts forward targeted prevention and control measures and emergency disposal methods.
