摘要
拖动水泵运转的电动机是泵站能耗的主要设备之一,研发和选用高效电动机对实现泵站节能有重要意义。这种电动机通过采用新技术、新材料、新工艺,包括改变其内部结构实现变极调速等,以降低损耗、提高效率。在阐述了节能高效电动机概念及其本体节能和调速节能的基础上,以无滑环绕线式异步电动机和双速凸极同步电动机在泵站中的应用为例进行了节能分析。结果表明,采用这种电动机与传统的电动机相比,其能耗节约率分别为4.33%和26.2%,推广到全国大型灌溉排水泵站更新改造的部分机组,年节电量可达3.58亿kWh,约占其机组年消耗电量的7.84%,经济效益显著。
As motor is the main equipment of energy consumption,research and selection of them with high efficiency is significant for energy saving of pumping station.These types of motor cut down on wastage and improve efficiency by the way of using new technology and material,including redesigning the inner structure to achieve pole-changing control,etc.The conception of energy-saving motor is mentioned.Then take wound-rotor asynchronous motor without slip rings which and double-speed salient-pole synchronous motor for examples,compared with traditional motors,noumenal improvement and speed control ways can save 4.33% and 26.2% electrical energy with great economic benefit.Popularized in some large-scale pumping station,they will save 0.358 billion kWh yearly,which is 7.84% of the whole power consumption in large-scale pumping station of China.
