摘　　要：超高压电气设备交流耐压试验一般采用变频谐振法获得高电压,回路的电晕损耗是试验的主要损耗之一,使用铝箔材质的扩径加压导线可显著降低回路的电晕损耗。但铝箔材质的扩径加压导线在大风作用下存在风偏角大、振动剧烈等缺陷,针对上述缺陷提出了一种可用于超高压电气设备交流耐压试验的新型防风抗晕加压导线,并对其力学性能和电气性能进行了研究。最后通过现场试验证明了该导线在防风和降低电晕方面具有良好的特性。As the high voltage is obtained by the way of frequency-regulating resonance method in EUV electrical equipment AC voltage withstand test, the corona loss is the main loss in this circuit, which can be reduced significantly by using extended diameter aluminum foil conductor. The extended diameter aluminum foil conductor has the defects of big wind deviation angle and excessive vibration when applied in the bad weather. Therefore, a new windproof and corona prevented conductor was proposed for the AC voltage withstand test of EHV electrical equipment, whose mechanical and electrical properties were also studied. Finally, field test results prove that the new conductor has better characteristics in windbreak weather and reducing corona.
