我国高压变频器的发展现状
目前,我国约有20家左右的高压大功率变频器生产厂家,如利德华福、东方凯奇(现东方日立)、成都佳灵、中山明阳、广州智光、上海科达、山东风光、合康益盛、九洲电气等。
由于美国罗宾康公司没有在中国申请*保护,因此绝大多数厂家都采用他的技术即单元串联多重化结构。深圳市英威腾电气股份有限公司则采用拥有自主知识产权的技术,开发出CHH系列矢量控制的高压变频器,2009年已试生产了40台,2010年已经批量生产了107台。
随着技术研究的进一步深入,在理论上和功能上国产高压变频器已经可以与进口变频器相比肩,但是受工艺技术的限制,与进口产品的差距还比较大,这些状况主要表现在如下几个方面:
(1)国外各大*的产品正加紧占领*,并加快了本地化的步伐。
(2)具有研发能力和产业化规模的企业逐年增加。
(3)国产高压变频器的功率也越做越大,目前国内大能做到8000KW。
(4)国内高压变频器的技术标准还有待规范
