电机能耗占比高,节能潜力大。通过对电机变频调速可平均节能30%以上,节能效果显著。伴随着节能政策的推广,变频器行业将迎来新一轮发展。据预测,中国潜在的节能市场规模达8000亿元。但国内变频器与国外变频器还存在一定的差距,其主要表现在以下几方面。首先,技术开发难度大,目前国内诸多变频器生产厂家都在高压变频器研发投入大量的人力与物力,力求在变频器技 Motor energy consumption is high, energy saving potential. Through the motor frequency control can save energy by more than 30%, energy-saving effect is remarkable. With the promotion of energy-saving policies, the inverter industry will usher in a new round of development. It is predicted that China’s potential energy-saving market size reached 800 billion yuan. However, there is still a certain gap between domestic inverters and foreign inverters, which are mainly reflected in the following aspects. First of all, technology development is difficult, many domestic inverter manufacturers are in the high-voltage inverter R & D invested a lot of manpower and material resources, and strive to inverter technology
