摘　　要：与超高压变压器相比,特高压变压器在电压等级、容量上均有了明显提升,结构也更加复杂,不仅包含主变压器,还配有调压变和补偿变,从而使得特高压变压器一次注流试验时电流回路尤为复杂。为此对特高压变压器一次注流时各绕组电流值进行分析,并以泰州特高压变电站为例验证其正确性。Compared with EHV transformer,UHV transformer is improved in voltage level and capacity.Its structure is more complex.Besides main transformer,regulating transformer and compensation transformer are also equipped.These characteristics make current circuit complicated when doing primary current injection test.To this end,the current value of each winding during the primary injection of UHV Transformer was analyzed,and Taizhou UHV substation was taken as an example to verify its correctness.
