| 摘 要： | 1000kV变压器是特高压交流输电工程最关键的设备之一。文章对1000kV变压器3个绕组(高压绕组1000kV,中压绕组500kV,低压绕组110kV)之间的过电压和绝缘配置进行了深入探讨,以期进一步完善特高压系统的绝缘配置、改善特高压变压器抵御过电压的能力和运行工况。推荐了1000kV变压器500kV绕组高性能避雷器的参数,可为降低变压器500kV绕组的绝缘水平、改进特高压变压器的结构设计及提升容量等提供参考。

| Abstract: | The 1 000 kV transformer is one of the most important equipments for 1 000 kV AC power transmission project. In order to further advance the insulation configuration of UHV systems and enhance its ability to withstand overvoltage and improve its operation condition,the overvoltages among three windings of 1 000 kV transformer,i.e.,high voltage winding with rated voltage of 1 000 kV,medium voltage winding with rated voltage of 500 kV and low voltage winding with rated voltage of 110 kV,and insulation configu... |
