摘　　要：特高压换流变压器的现场局部放电试验电压等级高,现场环境复杂,试验要求高。在对称加压方式下,存在被试品端部电位差大,电抗器补偿调节和电压电流测量不便等问题。为获得合理的电抗器补偿方式,减小对称加压方式下各端部电压差,研究了特高压换流变压器电容网络的等效方法,并根据现场试验的参数进行仿真研究,获得了补偿电抗器参数。On-site partial discharge test of Ultra High Voltage （UHV） converter transformer requires good anti-jamming measurement and response capability due to high test voltage, specific requirement and complex field environment. Under symmetrical voltage applying mode, there is large potential difference at transformer winding terminal. It is also inconvenient to adjust reactor compensation and measure voltage and current. The equivalent method of capacitance network of Ultra High Voltage converter transformer is studied. Based on on-site test results, the simulation is performed and compensation reactor parameters are obtained,
