目 录 3.1 变频调速的基本控制方式与基准电压、基准频率的关系. 11 摘 要
变频器调速技术是集自动控制、微电子、电力电子、通信等技术于一体的高科技技术。随着科学技术的高速发展,变频器以其具有节电、节能、可靠、高效的特性应用到了工业控制的各个领域中,如变频调速在供水、空调设备、过程控制、电梯、机床等方面的应用,保证了调节精度,减轻了工人的劳动强度,提高了经济效益,但随之也带来了一些干扰问题。因此有必要对变频器应用系统中的干扰问题进行探讨,以促进其进一步的推广应用。 关键词:变频器;应用; Abstract
The frequency changer velocity modulation technology is technology and so on collection automatic control, micro electron, electric power electron, correspondence to a body high tech technology. Along with the science and technology high speed development, the frequency changer to it had the electricity saving, the energy conservation, reliably, the highly effective characteristic applies in industry control each domain, like the frequency conversion velocity modulation in aspect the and so on water supply, air conditioning equipment, process control, elevator, engine bed application, had guaranteed the adjustment precision, reduced worker's labor intensity, enhanced the economic efficiency, but has also brought some disturbance questions along with it. Therefore has the necessity to carry on the discussion to in the frequency changer application system disturbance question, promotes it further promotion application. Key word: Frequency changer; Using; |
