电力变压器是电力输送的关键电气设备,变压器损耗占电网损耗的30%~40%,我国变压器自身损耗占全国发电量的3%以上。我国的《节能减排“十二五”规划》详细稿中要求“十二五”期间降低电力变压器损耗,其中空载损耗降低10%~13%,负载损耗降低17%~19%,目前在网运行的部分高能耗配电变压器已不符合行业发展趋势。国家一直在推动变压器的节能降耗工作。目前我国节能配电变压器市场散乱,加上入行门槛低、 Power transformers are the key electrical equipment for power transmission. Transformer losses account for 30% to 40% of the power grid losses. The losses of transformers in our country account for more than 3% of the national power generation. China’s “energy-saving emission reduction,” “Twelfth Five-Year Plan,” a detailed draft requirements “Twelve Five ” during the reduction of power transformer losses, including no-load loss reduced by 10% to 13%, load loss reduced by 17% to 19 %, At present some of the high-power distribution transformers operating in the network are not in line with industry trends. The country has been promoting the energy-saving transformer work. At present, China’s energy-saving distribution transformer market is fragmented, coupled with low barriers to entry,
