摘要
分析造成低压配电线缆因长期过载引发短路而造成电气火灾隐患的原因。通过对民用建筑中常见非线性用电设备的电流波形数据计算和其组合特性的分析,提出在民用低压配电线缆截面选择时,应考虑谐波过载因素。
This essay analyzes the causes for electrical fire hazards because of short outs caused by long-term overload of low voltage distribution cables.By calculating the current waveform data of the common nonlinear electric equipments in civil buildings and analyzing the combined features,this essay proposes that the problem of harmonic overload be considered in the choices of the sections of civil low voltage distribution cables.
