摘要
为考核 5 0 0kV方正变和方哈线一次设备的质量 ,对其进行了零起升压试验 ,并对零起升压过程中电压迅速上升的原因进行计算分析 。
In order to check the primary equipment for 500 kV Fangzheng Transform Line and Fangha Line for quality, tests were run with these equipment for stepping up from zero, and the causes for rapid voltage rise during stepping up from zero are analysed through calculations, and countermeasures are proposed for abnormalities experienced during tests.
