Can electric heat tracing be used during thunderstorm weather
在雷雨天气下,大型油罐通常储存大量易燃易爆油品。在室外环境中,如果被雷击,可能会发生严重的火灾和爆炸事故,对油箱造成损坏。考虑安装电伴热时,油箱受到雷电感应时,会在金属导体上产生感应电动势和电流。如果导体上某一点的接触电阻高或有间隙,就会产生热点或电弧。
当雷暴在地面物体上产生感应电荷时,与地面相对绝缘的物体上的静电在雷暴放电后变成自由电荷。当物体上有较大的局部电阻或较小的间隙通向地面时,在发热部分之后也会产生电弧火焰。因此,油罐的防雷接地极是非常重要的。
很多用户关心的是电加热带在雷雨天气下的安全性?电加热带的结构本身有一个屏蔽层,用镀锡铜线或其他金属线编织而成,用于接地,防止漏电。电加热带的接地电阻较小,可以安全地将雷电引至地面,确保其安全性能。采购电伴热带当然要选择正规电伴热厂家生产的产品才更有保障,如果大家需要电伴热带,管道伴热带,可以联系芜湖市恒鑫电缆有限责任公司。
