摘　　要：现场特殊试验对于加强电力设备入网检测水平,提升特高压直流输电工程建设质量与效率具有十分重要的意义。结合±800 kV云广和普侨直流工程建设实际,对比分析串联谐振和并联谐振的特点及应用范围;结合换流变压器长时感应电压带局放测试和交流外施试验等,对特高压直流输电工程建设中谐振试验装置的应用方法和关键技术进行了探究,研究结论对后续特高压直流输电工程设备现场特殊试验具有参考和指导价值。Special field test has very important sense to enhance the grid detection level of power equipment and the quality, efficiency of UHVDC transmission project. Combined with ±800 kV Yunguang and Puqiao DC transmission project, this paper compared and analysed the characteristics and application range of series resonance and parallel resonance. Combined with the long-duration induced AC voltage （ACLD） test and AC applied test of converter transformer, the application method and key technology of resonance test apparatus in UHVDC transmission project construction had been studied, which had reference and guiding significance for the special field tests of subsequent UHVDC transmission project.
