摘要
论述了大电流中压开关设备运行中振动噪声产生的主要原因和产生机理,介绍了计算机仿真分析技术在电磁产生噪声研究方面的应用,通过计算结果与实验测量的对比,验证了数值计算的可靠性和降噪措施的有效性,总结出一些指导大电流产品设计、制造的规律。
The paper analyses the main reasons and mechanisms which caused the vibration noise of the high current switchgear, and introduces the computer- based emulating technique used in the research on the vibration noise caused by the electromag-netic effect. By the comparison between the calculated results and the testing/measurements, the reliability of calculated values and validity of the method on reducing the noise have been proved. The designing laws on high current products have been gained.
