电伴热1米多少功率?

信息来源:皖缆集团 浏览次数:2874 发布时间:2017-11-08

    电伴热1米多少功率?是要看产品的规格型号的,通常电伴热体或说明书上会有标示(如下图)。标示的功率是“额定功率”,即10℃时的发热功率。
电伴热1米(每米)耗电量的计算
    公式:P=W/t 表示功率等于单位时间做的功,总功W=Pt=UIT=UP;W:表示“功”,t:表示“时间”,P:表示“功率”,I:表示“电流”,U:表示“电压”,R:表示“电阻”。例如耗电量的计算:W=Pt=每米功率25瓦×24小时=600瓦。
    计算电伴热耗电量要注意“额定功率”是在10℃时的发热功率,耗电量大小会受到使用环境和伴热要求的影响。
