| 摘 要： | 交流接触器在不同的使用类别情况下,应规定不同的额定工作电流。分析了4种使用类别下的使用情况,从实际负载起动电流去探求AC-4的额定工作电流。还分析了其他几个影响额定工作电流的因素。经分析得出,如果电压、功率因数、操作频率、负载因数等其他相关因素比一般情况更加恶劣,应将Ie4与Ie3的比值再适当减小一些。

| Abstract: | Under different use categories,AC contactor should be regulated with different rated working current.Analysis was made to use conditions of 4 kinds of categories, the rated working current of AC-4 should be found out from actual load start current. Analysis was also made to several factors which have impacts on rated working current. After analysis, it is found if voltage, power factor, operating frequency, load factor etc other related factors are much worse than normal conditions, so the ratio of Ie4 and Ie3 should be suitably reduced a little. |
