摘要
“三相异步电动机半电压叠频温升试验”主要就是将国家标准中推荐的“降低电压负载法”和“定子叠频法”有机地结合起来,分别进行“空载状态下的温升试验”和“半载状态下的叠频温升试验”,并把试验的结果,利用有关的公式进行计算,来推算满载时绕组的温升。
‘haft-voltage superposing-frequency temperature-rise test of 3-phase asynchronous motor＇ is to fully combine ‘ dropping-voltage load method＇ and ‘stator superposing-frequency method＇ , which are recommended by state standard. It can respectively carry out ‘ temperature-rise test at non-load state＇ and ‘ superposing-frequency temperature-rise test at haft-load state＇. We can calculate the test result and conclude stator temperature-rise at full-load state with relational formula.
