我国首批750 kV电气主设备的研制与应用

我国750 kV输变电示范工程是海拔最高、污秽最严重的输变电工程,也是目前国内电压等级最高的输变电工程,对电气主设备的制造提出了很高的要求。各设备制造单位充分吸收国外经验,并借鉴国内超高压设备研制的经验,对设备技术性能进行改造,研制出了我国首批750 kV级电气主设备,整个工程的电气主设备国产化率达到90.2%,为后续750 kV和1 000 kV的设备制造提供了借鉴。

Development and Application of 1st Batch 750 kV Electrical Main Equipment in China

The 750 kV demonstrated transmission project in China is the project at the highest elevation above sea level and with most serious dirty.It is also the project with the highest voltage level at present,which requires high level for production of main equipment.Absorbing foreign experiences and referring to domestic experiences on development of EHV equipment all domestic manufactures have make renovation on technical performance and developed the 1~(st) batch of 750 kV main electrical equipment.The localization ratio of the main electrical equipment for the whole project has reached 90.2%,which is a reference for manufacture of following 750 kV and 1 000 kV equipment.
