工矿企业是能耗大户,而其中的电力能耗占大部分,因此,工矿企业的节电,则是电气设计时必须考虑的主要内容,由于电气设备及电气技术上的进步,在进行电气节能设计时应综合运用各种新设备,新技术。节约能源是我国的基本国策,国家制定了节能中长期专项规划,为落实此规划目标,国家发改委最近启了十大重点节能工程,节能工 Industrial and mining enterprises are large energy consumers, of which the majority of electricity consumption, therefore, energy-saving industrial and mining enterprises, it is the electrical design must consider the main elements of the electrical equipment and electrical technology advances in the electrical energy-saving The design should be integrated use of new equipment, new technologies. Energy conservation is China’s basic national policy, the state formulated a long-term energy-saving special plan, in order to implement this planning goal, the NDRC recently opened ten key energy-saving projects, energy-saving workers
