摘要
为改善交流接触器的电磁系统所消耗的有功功率及无功功率,我国20世纪70年代涌现出许多节电方案与产品,本文介绍了十余种方案并进行了大量分析研究。后由主管单位组织制定全国统一的交流接触器节电器标准,于1988年公布实施,又在2000年修改并公布。文章介绍了标准的主要内容,最后还提供一些节电应用线路,使用户及制造单位对节电器有较全面的理解。
To improve on consumption on the effective and reactive Power by an electromagnetic system of AC contactors,programs for power saving and relevant products emerged in large numbers in 1970s.This paper presents more than ten progams and makes an intensive analysis and research on them .The competent authorities organized and worked out the unified standard for the power-saving device of Ac contactors the whole country.which was published and performed in 1988,and revised and republished in 2000.This paper presents the main contents of the standard above,with some power-saving application circuits recommended finally,thus making customers and manufacturers
comprehensively understand the power-saving device.
