农用电动机节电运行技术与管理措施

异步电动机在农业生产和农业工程中应用极其广泛。根据初步统计,目前我国农用电动机消耗的电能约占全国农村电能的70%以上。由于选型、使用不当和管理不善等原因,农用电动机普遍存在着“马拉空车”、“大马拉小车”、功率因数偏低等现象,致使农村电网容量不能完全被利用,大量的能量被白白地浪费掉。鉴于此,该文详细论述了农用电动机的各种节能运行、技术改造和技术管理的措施,以及抑制谐波、调节无功的新技术,来提高电动机的效率和农网的功率因数,这些举措有利于提高农村电力拖动的经济效益

Energy-saving Technologies and Operational Management of Agricultural Motors in China

Nowadays some medium and small sized asynchronous motors are widely used in agricultural production and engineering. According to incomplete statistics, 70% of the power of rural electric lines has been drained by rural motors at present. On the one hand,because of incorrect management, choices of types and application of rural motors, problems such as idle running, insufficient usage and low power factor are quite common. Thus the capacity of the rural lines is not in full play. On the other hand, a lot of rural lines lack reactive compensation devices, and harmonic pollution becomes more and more serious in the modern countryside, which leads to low voltage quality and a lot of line loss. In view of these facts, this paper expounds a new project on various energy-saving operations, technological innovations and management, which reduces rural harmonic power losses and increases reactive compensation. This will play an important role in improving the economic benefit of agricultural motors and the rural power network system in China.
