摘要
分析了饱和电抗器及接头发热的原因,提出了降低电抗器内部发热的方法,分析了接触电阻的影响因素,对改进措施进行仿真校核并进行了温升测试。
The cause of the heat generation of the reactor and it’s joint is analysed.The method for reducing the internal heat generation of the reactor is proposed.The influencing factors of the contact resistance are analyzed,and the improvement measures are verified by simulation and temperature rise test.
