摘要：
1000 kV Jindongnan-Nanyang-Jingmen ultra-high voltage (UHV) AC Pilot Project is the highest power transmission voltage level in China. It is also the first time to carry out partial discharge test with 1000 kV and 1000 MVA UHV AC power transformer in China. The test is very difficult due to the high voltage and strict demand in partial discharge level. In this paper, the ODFPS-1000000/1000 UHV transformer made by TBEA, which is locating at Jingmen substation, is taken for an example to analyze its pre-delivery partial discharge test. Partial discharge test types for bushing 1000 kV Jindongnan-Nanyang-Jingmen UHV AC Pilot Project Electrical Apparatus Hand-over Test Standard from State Grid Corporation of China and hand-over test. The characteristics of UHV transformer partial discharge are summarized and special requests for UHV transformer test are put forward.
