目前,我国由电气所引起的火灾居高不下,据有关资料表明,电气火灾数占了火灾总数的30%左右,给国家经济和人民财产造成了巨大损失。电气火灾的成因到底是什么,如何防范电气火灾已是我们电气工作者所面临的共同课题,值得也需要我们更多地思考与探索。1电气火灾成因电气火灾原因较复杂,在我国目前还没有一个统一的分类标准。总的归纳起来,基本包括有如下几个方面:过电流、非正常剩余电流、高次谐波电流、过电压、电弧或电火花、雷击、热传导、余
At present, the fire caused by the electricity in our country remains high. According to relevant information, the number of electrical fires accounts for about 30% of the total number of fires, causing huge losses to the country’s economy and people’s property. What is the cause of electric fire in the end, how to prevent electrical fire has become a common issue facing our electrical workers, it is worth also need our more thinking and exploration. A cause of electrical fire Electric fire causes more complex, in our country still do not have a uniform classification criteria. Generally summed up, basically includes the following aspects: overcurrent, abnormal residual current, higher harmonic current, over-voltage, arc or spark, lightning, heat conduction, more than
