“低压电器行业水涨船高的日子在未来五年不会有了。与此同时僧多粥少,竞争越来越激烈。国内中低端产品,特别是柳市,低压电器产品没有**只有更低。
未来五年,低压电器特别是中低档的低压电器格局会有很大变化。”德力西电气战略及市场部副总裁张连权表示。
近几年,国内的低压电器需求都处于扩张状态,低压电器行业销售收入呈逐渐增长态势,不过,在低压电器市场良好发展的同时,市场也暴露出各种各样的问题。
企业规模偏小、且数量过多、产品同质化严重、竞争激烈等屡遭诟病。低压电器行业亟待摆脱低端化尴尬。
智能电网为低压电器提供转型契机
我国近年来智能电网与新能源建设工程正在不断推进,低压电器市场也随着产品应用范围的扩大,进入**增长阶段。
“十二五”期间,随着智能电网建设的推进以及低压电器生产技术的不断发展,以智能化、模块化、可通信为主要特征的新一代低压电器将成为市场主流产品。中高端低压电器市场份额将进一步扩大。同时在产业结构调整、降低国内生产总值的能耗、实现低碳经济发展的背景下,新一代节能、节材、高性能的低压电器产品将得到更大的发展,市场需求日趋旺盛,也为低压电器行业的转型、升级提供了难得契机。
新能源的**发展为产业延伸提供了发展机会,低压电器行业的产品向光伏发电逆变器、新能源控制与保护系统、分布式能源、储能设备、直流开关电器设备等领域扩展,并能提供整体解决方案,这一领域是低压电器行业新的重要经济增长点。
事实上,因为我国低压电器在高端领域品牌**不足,智能化程度低,市场占有率一直不高,产品亟需向智能化方向转变。那么,何为低压电器智能化?到目前为止,国内外低压电器标准还没有对低压电器智能化进行定义。但被业界普遍认可的是,智能低压电器必须具有四个功能基本特征,即保护功能非常齐全、测量实时电流参数、故障记录与显示、内部故障自诊断等。
“实际上,我国一些低压电器生产规模较大的企业,已经能做到产品智能化,但多年来,用户方对产品质量和品质的顾虑,导致对低压电器行业信心不足,德力西的低压电器产品应用于航天工业,证明我国企业产品质量是有保证的。企业需要不断努力,通过几十年把真正的中国品牌做上去。
国外的品牌有上百年的历史,而要将柳市的产品做到用户单位足够的信任,还有一定的距离。”浙江省电气行业协会执行副会长黄忠平说。
低压电器需建立行业标准体系
“目前中国的低压电器行业是处于中等偏上的水平,不能说是**水平。但我国低压电器行业从工艺、设计、制造这三个方面还要花很大的力量。我们的性能跟国际不会差太远,甚至有些是超越了,但是可靠性不行。”国网智能电网研究院研究员何江认为。
那么可靠性如何推行,还需要标准体系的建立,为低压电器行业把脉。随着低压电器产品的更新换代,标准也将逐步完善。
若建立相应的标准,就应首先把准低压电器产品未来发展脉络。业内**认为,未来低压电器产品的发展将主要表现为产品智能化,市场需要高性能、智能化的低压电器产品,并要求产品具有保护、监测、试验、自诊断、显示等功能;带有通信接口,能与多种开放式现场总线进行双向通信,实现低压电器可通信、网络化;开展可靠性设计,
产品生产过程进行可靠性控制(大力推进在线检测装置)、可靠性出厂检验等,特别强调电子器件可靠性及电磁兼容要求;强调环保节能要求,逐步发展“绿色”产品,包括产品材料选用、制造过程及使用过程对环境的影响,能源的有效利用。
相对于行业技术发展趋势而言,**指出4种技术标准需迫切研究:一是能够涵盖**产品综合性能,包括技术性能、使用性能、维护性能的技术标准;二是产品通信及产品性能与通信要求有机结合的标准,以使产品具有较好的互操作性;三是制定相关产品的可靠性和试验方法标准,以提高产品可靠性及产品质量,加大同国外产品竞争的能力;四是制定系列环境意识设计标准和低压电器产品的能效标准,指导并规范企业生产制造节能环保的“绿色电器”。
此外,何江认为,我国低压电器整机可靠性标准的制定工作尚处在初级阶段,覆盖面窄,没有形成体系,因此难以确认产品的可靠性水平。所以,目前亟须建立和实施低压电器产品可靠性评价及召回制度,加强可靠性标准体系建设,逐步建立国家标准、行业标准和企业标准体系,形成层次分明、互相衔接、各有侧重的可靠性标准构架,能够对产品可靠性进行全方位的评价。
