自“十二五”规划出台以来,节能减排已经成为各行各业发展中的一项重要任务。在工业领域,节能手段主要包括结构节能、技术节能和管理节能,其中技术节能是指采用新工艺、新设备、新技术和综合利用等方法,提高能源利用率。变频器作为一种自动化程度高的电子调速设备,不仅可以改善工艺、延长设备使用寿命、提高生产效率,更重要的是变频技术的节能作用日益凸显。
工业节能的 “利器”
在新型工业化发展战略的推动下,现在国内钢铁、制造、纺织、电力等工业领域的设备改造和产业升级正全面展开,同时基于市场竞争的不断加剧,节能降耗已经成为降低生产成本、提高产品竞争力的重要手段之一。
业内人士指出,变频器的**初用途是用来速度控制,随着技术发展和社会对能源运用效率要求的日益提高,逐渐被用于节能领域。其节能主要用在需要通过实施交流电机转速变化,改变驱动机械特性从而达到生产工艺要求的场合,较多地应用在风机、水泵上。使用变频器的电机系统节电率普遍达30%左右,某些较高场合可达40%~50%,节能效果非常显著。可以说,变频器已经成为电机节能的发展方向,其市场潜力非常巨大。
不过,业内人士也同时表示,变频器系统是一种高技术含量的高科技产品,涉及多方面的应用技术,对研发生产、工业设计有着极高的要求。比如,绝缘栅双极晶体管(IGBT)是变频器的核心部件,目前国内IGBT市场仍主要由一些拥有**技术优势的外资企业所把控。再有,变频软启动属于中压变频器的高端应用领域,具有很强的特殊性,更是只有具备强大技术实力的厂商才能满足相应需求。
目前,在工业自动化市场建立了广泛品牌**度的变频器厂商中,艾默生网络能源基于深厚的电力电子研发经验和技术实力,在变频器市场成功确立了**优势,其品牌**和产品应用范围日渐扩大。
实现节能目标的**
艾默生网络能源相关人士表示,变频器业务在艾默生网络能源整体业务发展中占有重要地位,这也是公司不断加大变频器技术产品研发投入的因素之一。艾默生网络能源对变频器业务的布局,始终都是围绕帮助客户解决实际问题以及取得**化节能收益的角度出发,这与艾默生网络能源始终注重提升客户价值的发展理念一脉相承。
毋庸置疑,针对市场需求的研发投入,换来的就是丰富的成果。在长期的技术积累和潜心研发下,艾默生网络能源不断完善变频器产品系列,持续推出极具竞争力的高端产品。此外,在为工业客户提供**的高质量产品的同时,艾默生网络能源将提供系统的解决方案视作变频器业务的一个重要战略,并实现了向变频器解决方案供应商的华丽转身。
据艾默生网络能源相关人士介绍,MegaVert中压变频器是艾默生网络能源变频器产品系列中一款具有代表性的产品,是艾默生网络能源在变频器领域取得的一项重大突破。作为一款自主研发生产的IGBT型中压变频器系统,MegaVert中压变频器集中采用了****电力电子技术,具有高功率因数、高可靠、高性能、多功能、易操作、易维护等突出特点。该系列中压变频器采用SPWM控制技术,能够帮助工业客户在生产过程中有效提升设备的控制水平及运行效率,满足工艺控制要求,更重要的是大幅降低电机能耗,促使客户圆满实现节能减排目标。
实际应用是检验产品性能的 “试金石”。可以说,MegaVert中压变频器工程与技术完美结合的设计以及出色的性能深得工业领域客户的一致青睐,并得到了广泛的应用,很好地推动了国内中压变频器市场的发展。例如在龙钢5#高炉鼓风机组27MW电机变频软起动项目中, MegaVert中压变频器以其卓越的品质轻松化解了项目应用中变频器容量大、控制要求高、同步切换技术复杂的挑战,为龙钢在节能减排、提升工艺水平上取得了良好的效果。
从变频器行业前景来看,基于巨大的市场规模,吸引了众多企业加入这一行业,竞争日趋激烈。同时,从实际应用中的重要作用来看,变频器需要能够以出色的性能帮助客户解决实际问题,为客户带来显著的核心价值,这对厂商的技术实力和研发水平提出了很高的要求。不过,以艾默生网络能源为代表的主流厂商,正以**的技术优势和研发实力,有力地引领着这一行业的发展潮流,促使变频器研发技术实现更大提升。
