摘　　要：采用振荡型冲击电压进行电气设备的现场冲击试验具有电压产生效率高、易于现场实施的特点,利用变压器的感应式原理进行操作冲击电压的产生则可进一步减小试验设备的体积。基于感应式原理,研究了变压器现场振荡型操作冲击电压试验技术。在理论分析的基础上,对1台110 kV变压器进行了现场试验,并利用铭牌参数进行了仿真研究。试验和仿真结果表明,利用本文所研究的方法,可以在现场产生符合标准要求的振荡型操作冲击电压。实现变压器的现场操作冲击电压试验。The oscillation impulse voltage test of power equipment has high efficiency and is easy to implement in field. The volume of generation equipment can be reduced by using inductive principle to generate the operate impulse voltage. The oscillation impulse voltage test technology for power transformer is studied in this paper based on inductive principle. A 110 kV transformer is used to carry out the field test based on theory analysis. The simulation is carried out using transformer parameters. The experiment and simulation results show that the oscillation impulse voltage waveform that meet the requirement of standard can be generated according the method provided by this paper.
