专家泼冷水学生网购变压插座破解宿舍限电

华中师范大学对学生寝室的额定功率定为800瓦，可以保证寝室成员同时使用电脑、电灯、电扇等较小功率电器，但学生若使用热得快、电吹风等大功率热阻电器，寝室会自动断电几分钟再恢复。华中科技大学去年底也添置了新型智能电表，限制学生使用各类大功率热阻电器，以保证用电安全

华中师范大学对学生寝室的额定功率定为800瓦，可以保证寝室成员同时使用电脑、电灯、电扇等较小功率电器，但学生若使用热得快、电吹风等大功率热阻电器，寝室会自动断电几分钟再恢复。华中科技大学去年底也添置了新型智能电表，限制学生使用各类大功率热阻电器，以保证用电安全。

出于安全目的，在大学宿舍里，热得快、电吹风等热阻电器往往都被禁止使用，一旦有同学使用，往往就会出现开关跳闸断电。近日在淘宝上热销的一款名为“宿舍神器”的变压插座，却宣称使用之后能躲过跳闸，“逃离”电流保护器检测。记者了解到，武汉有部分大学生已买此产品，来逃离学校的限电措施。专家表示，使用此“神器”会带来安全隐患。

华中科技大学紫菘学生公寓一名楼管说，去年12月该公寓有学生忘记拔掉热得快插头险些引发火灾。学校的限电措施和过往的教训并没能阻止一些学生使用大功率热阻电器，近来在淘宝上卖得火热的“宿舍神器”受到部分大学生追捧。

华中科技大学学生刘涛（化名）9月花费40元购置1个“宿舍神器”。她告诉记者，她的电吹风是1200瓦的，用这种“宿舍神器”虽风力小，“但是总比不能用好”。淘宝商家称，只要将这种特殊的插座插在寝室内的插口上，就可以接用电热壶甚至电饭煲等大功率热阻电器。记者昨日了解到，“宿舍神器”种类不同，售价一般在数十元至百元之间，其工作原理就是让电压电流处于一种不正常工作状态，以此“骗倒”检测设备。

华中科技大学电气与电子工程学院副教授林磊介绍，“宿舍神器”让电能得不到有效利用，实际上只使用了一半，另一半消耗在电线上，既浪费电又易引发火灾。
