基于“一控多”变频装置的节能技术应用

Application of Energy Saving Technology Based on One Invertor Device Controls More Motors

采用变频技术是实现节能的有效手段,而且已被广泛运用于水处理行业。往常采用的"一对一"变频装置设置方式,由于大功率变频器价格昂贵,投资较大,浪费能源。建议变频装置采用"一控多"形式,在不增加投资的前提下可以获得相同的效果。通过工程实例就对变频控制的原理及效果进行了简析。

The frequency conversion technology is an effective measure to realize the energy saving.It has been widely used in the water treatment.The method that one inverter controls one motor usually needs more capital input and consumes more energy.The method of one inverter controls more motros should be adopted,because it can realize the same control effect under no more capital input.Through one engineering project,the principle and effect of frequency conversion control were briefly analyzed.
