摘　　要：高电压、大容量的阻容性电气设备交流耐压在工程中的应用场景十分丰富,为了优化试验容量,串并联混联谐振这一技术逐渐应用,其思想为通过并联电感先与试品欠补偿,使得混联后的谐振容量得以减小,提高试验能力。面向混联谐振交流耐压这一实际问题,研究了其拓扑组合,在不同组合方式下讨论了谐振特征参数的计算并验证其合理性,给出现场交流耐压试验的指导意见。The AC withstand voltage of high-voltage and high-capacity resistance capacitance electrical equipment has rich application scenarios in engineering.In order to optimize the test capacity,the technology of series parallel hybrid resonance is gradually applied.The idea is to reduce the resonance capacity after hybrid connection through the under compensation of parallel branch and test object.Facing the practical problem of hybrid resonant AC withstand voltage,this paper studies its topology combination,discusses the calculation of resonant characteristic parameters under different combination modes,and verifies its rationality,so as to give guidance for on-site AC withstand voltage test.
