三相异步电动机型式试验分析系统设计

Analysis system design of the three-phase asynchronous motor type test

型式试验是电机出厂前的一个必要的测试环节,但与之相对应的分析系统却相对短缺,针对这一问题,根据国标GB/T1032-2012,以Microsoft Visual Studio为平台,开发了一款三相异步电动机型式试验分析软件。首先介绍了试验项目,给出了试验特性曲线类型,以及试验目的和试验方法;然后详细阐述了多次自适应最小二乘法曲线拟合的分析方法;最后以某电机的现场试验证明,系统能够准确地分析电机各性能指标并达到型式试验要求,具有很好的实用性。

Type testing is necessary before motor leaves the factory,but the analysis system corresponding with the type testing is relatively short. Aimed at the question,according to the national standard GB/T1032-2012,a analysis software is designed of three-phase asynchronous motor type test based on Microsoft Visual Studio. Firstly,this paper introduces the test items and gives out the type test characteristic curve and test purpose. Secondly,the analysis method of least squares of many times is stated detailedly. Finally,a field test of motor proves that the system can analysis accurately the all kinds of performances to achieve the requirements of type testing and indicators of motor and has a good practicability.
