摘　　要：针对XLPE电力电缆耐压测成本高、操作复杂等问题,设计了一种变频串联谐振耐压试验装置。利用串联谐振电路的升压原理,构建了硬件电路,通过仿真探讨了谐振点的选取问题。对于普通串联谐振耐压测试装置寻找谐振点慢、精度低的问题提出了一种解决方案。仿真结果表明,该方法能精确地确定谐振点,装置输出波形可靠性好,谐波分量少,具有良好的性能。Designed a kind of serial resonance voltage withstand test device for the problems of high cost and controlling complexity in XLPE power cable withstand tests. Took the advantage of the principle of network, built the hardware circuit, discussed some key problems through simulation. Created a method to improve the accuracy and the efficiency of general test device. Simulation results show that this method is accurate and efficient. The output waveform has a good performance.
