浅谈变频器在空压机节能改造中的运用与讨论摘要：随着电力电子技术的高速进展，变频器在调速领域中的运用越来越广泛。它具有性能稳定、操作方便、节能效果明显等显著优点。而空压机在工厂中能耗大、噪声大、自动化程度不高等缺点.现结合 PLC 与变频器对空压机进行节能改造，具有很明显的节能效果。而今在全球推动低碳经济,节能减排的大趋势下，如何节能、高效地解决空压机的节能减排问题,已经成为社会讨论的热点，而针对降低工厂空压机能耗对我国完成节能减排目标与推动建设为节约型社会具有非常重要的作用。关键词：变频器、可编程控制器(PLC)、工频、开环、闭环On the Inverter in energy saving in the use of air compressor and ResearchAbstract: With the rapid development of power electronics and inverter speed control in the field more and more extensive. It has stable performance ， easy operation, saving the obvious effect, a significant advantage. The air compressor energy consumption in factories, noisy, not high degree of automation shortcomings 。 PLC and inverter are combined with the air compressor for energy saving， energy saving effect is very obvious 。 Now in the global low-carbon economy, energy saving and emission reduction trend ， how energy—saving ， efficient energy saving solution to the problem of air compressors, has become a hot research, and reduce the plant air compressor for the completion of energy consumption in China emission reduction targets and promote the building of the conservation society has a very important role。Keywords ： converter ， programmable logic controller （PLC), Frequency, Open and Closed Loop 空气压缩机是气源装置中的主体，它是将原动机（通常是电动机）的机械能转换成气体压力能的装置，是压缩空气的气压发生装置。它的用途广泛,用于冶金、烟草、矿山、机械制造、石油化工、电力、纺织、造纸、制药等行业。空压机占大型用电设备（水泵、风机、锅炉、空压机）耗电量的 15％，所以选用改造空压机作为节能减排的重点具有很重要的经济...
