针对特高压设备的工频耐压试验存在测试系统复杂和对现场电源容量要求大的特点，提出了一种基于新型磁控式谐振变压器的紧凑型升压补偿一体化特高压工频耐压试验系统。该试验系统采用并联谐振补偿方案，结构紧凑。经仿真分析可知，该试验系统电抗调节范围宽，输出电压稳定，且能很好地实现对容性试品的动态并联补偿。当发生并联谐振时，输入功率减小为试品容量的1／27，补偿效果良好。经样机试验，验证了该试验方案的可行性。

英文摘要：

As the power-frequency withstand voltage testing system for ultra high voltage （UHV） equipment is complex and the required power capacity is large, a kind of compact UHV power-frequency withstand voltage testing system inte- grated with compensation and boost function based on a novel magnetic controlled resonant transformer is proposed. The proposed testing system uses the method of parallel resonant compensation, and has a compact structure. The simulation analysis shows that the testing system has the wide-adjustment of the excitation reactance and a stable output voltage. And it can realize the dynamic parallel compensation to capacitance loads. When the parallel resonance occurs, the input pow- er can be reduced to 1/27 of the sample capacity, and the compensation effect of the testing system is very good. The prototype tests validate the feasibility of the testing system proposed by this Daner.
