摘要(Abstract):
通过理论计算结合现场试验,介绍了调频式串联谐振技术在大容量发电机交流耐压试验中的应用。调频式串联谐振试验装置改变了用传统工频耐压试验装置进行大容量发电机交流耐压试验时的不足,具有重量轻、所需电源容量较小、电压波形好、适宜现场使用的优点。
This paper describes the application of frequency modulation series resonance technology in AC withstand voltage tests of large-scale generators through theoretical calculation and field tests.The test device of frequency modulation series resonance overcomes the disadvantages of the traditional power frequency withstand voltage test device in AC withstand voltage tests of large-scale generators.It has advantages of light weight,lower power supply capacity required,good voltage waveform and suitability for field tests.
