摘要
电机是设备动力和传动系统的核心,是风机、水泵、压缩机、机床、传输带等各种设备的驱动装置,广泛应用于石油、化工、冶金、农业、交通、市政等领域,是用电量最大的耗电终端设备.目前我国油田很多电机存在能耗高、效率低、老化严重等现象,已不符合国家现行能效标准,急需节能改造.对高效异步电机的结构和节能原理进行了介绍,给出了较为准确的节能量计算方法.采用高效异步电机进行的节能改造,节能效果显著,不仅给油田带来了可观的经济效益,而且产生了较好的社会效益.
Abstract
The motor is the core of the power and transmission system of the equipment.It is the driv-ing device of various equipment such as fans,water pumps,compressors,machine tools,and trans-mission belts.It is widely used in petroleum,chemical industry,metallurgy,agriculture,transportation,municipal and other fields.It is the most power-consuming terminal equipment with electricity con-sumption.At present,many motors in my country's oil fields have high energy consumption,low effi-ciency,and serious aging.They no longer meet the current national energy efficiency standards and are in urgent need of energy saving renovation.The structure and energy saving principle of high-effi-ciency asynchronous motors are introduced,and a more accurate calculation method of energy saving amount is given.The energy saving renovation using high-efficiency asynchronous motors has remark-able energy saving effects,which not only brings considerable economic benefits to the oil field,but al-so produces good social benefits.
