摘要：为了量化高压变压器寄生电容对电晕处理机系统工作频率的影响，通过实验获得了高压变压器单独工作和带电晕处理机负载两种工作条件下的实验波形，测取了这两种工作条件下系统的谐振频率，通过理论分析计算得到了高压变压器寄生电容值和电晕处理机负载的等效电容值。通过对比发现，目前实验装置下高压变压器寄生电容值高达电晕处理机负载等效电容值的1.5倍，此时系统谐振频率约为理想条件下变压器谐振频率的0.6倍，研究分析结果表明寄生电容的存在对电晕处理机系统工作频率具有重要的影响。

Abstract:In order to quantify the impact of highvoltage transformer parasitic capacitor on operating frequency of corona treatment machine, experiments using highvoltage transformer with and without corona treatment load were done, respectively. The resonant frequency was measured, the capacitance of highvoltage transformer parasitic capacitor and the corona treatment load was calculated. The highvoltage transformer parasitic capacitor is up to 1.5 times of the corona treatment load by comparing in the current system, and the resonant frequency is about 0.6 times of which when the transformer is ideal. The results show that the parasitic capacitor has an important impact on the operating frequency of corona treatment machine.
