电源插座过载火灾危险性分析

利用反复过载实验方法对电源插座分别采用1.5倍、2.0倍、2.5倍、3.0倍额定电流进行过载实验,在过载3次及6次后分别通以额定电流,得出了一系列温度—时间的变化曲线及相关数据,并进行了分析。在实验所得结果的基础上,分析了插座过载引起火灾的原因,并提出了相应的火灾预防对策,这对预防插座过载引起电气火灾,减少火灾损失具有重要意义。

A Fire Risk Analysis of Receptacles in the Case of Overloading

1.5 times,2.0 times,2.5 times,and 3.0 times of the rated current were adopted for this electrical overload experiments time and again.Besides,the rated current was used to flow through the receptacle after the 3rd and 6th experiments respectively,a series of temperature-time curves and the related data were gained,then an analysis was given based on the results.In the end,the fire causes of the receptacle in case of overload were learnt and the preventives measures were brought forward which is very importa...
