变频串联谐振耐压试验的原理分析及应用

Analysis and Application of Principle of Variable Frequency Series Resonant Voltage Withstand Test

变频串联谐振可以在试验变压器额定电压小于所需试验电压,但是电流额定值满足试品试验电流的情况下,在一定范围内实现与工频耐压试验基本等效。了解其原理及现场遇到问题时的解决思路对实际工作具有重要的指导意义。

In case of that the rated voltage of test transformer is less than the required voltage and the current rating meets the sample test current,within a certain range variable frequency series resonant can achieve basic equivalent with frequency voltage withstand test. The understanding of its principle and solutions for on-site problems encountered have important guiding significance for practical work.
