摘　　要：平衡系数是电梯的重要技术指标,也是法定定量的检验项目。多年来对电流法检测的数据和电流曲线的观察比对,发现很多数据和曲线形态以及检验结果差异很大。本文以典型检验实例和多年检验实践为基础,结合变频拖动电梯的工作原理,对所测电流数据和曲线进行了详细的技术分析,发现了问题根源,为今后相关检验机构和人员编制检验方案和实操检验提供了参考指南。Balance coefficient is an important technical index of elevator and a legal quantitative inspection item.Over the years,the author observed and compared the data detected by current method with the current curve,and found that many data,curve shapes and test results were very different.In this paper,based on typical test examples and many years of test practice,combined with the working principle of variable frequency drive elevator,the measured current data and curves are analyzed in detail,and the root of the problem is found,which provides a reference guide for relevant test institutions and personnel to make test plans and practical test in the future.
