不可不知的安全电源匹配常识

[ 2012-4-16 10:04:00 | By: 杨远锋 ]

现在家庭电器越来越多，有的电器功率还比较大。住户的用电负荷也越来越大，一般家庭用电系统的总负荷最低在1.5―2kv，电流约为8A；最高的总负荷在5kw左右，电流约为25A。如果你的家庭电器比较多，超出了住房设计的功率，就必须向电器工程师咨询后，方可使用。
　　家用电器按照功率的大小，一般可分为三个档次：
　　第一档次的为小功率电器，如电视机、电冰箱、洗衣机、电扇、排风扇、抽油烟机、组合音响、照明灯具等。这类电器的负荷大约为300―700w左右。　　
　　第二档次的中型功率的电器，如电吹风、微波炉、电饭锅、电熨斗、电烤箱、电热毯、吸尘器、电暖器等。这类的电器一般的负荷在700―1200w左右。　　
　　第三档次的为大功率电器，如空调机、电热水器、烧烤微波炉、暖风机、浴霸等，其负荷为1500―2500w左右。　　
　　安装大功率的电器，不得使用普通开关，不得直接安装在可燃的构件上。这类电器的安排要按产品安装使用说明书的规定要求，决不能凑合使用或抱有任何侥幸的心理。
